violates any of the provisions of the codes adopted in section 18-31 shall be deemed guilty of a
misdemeanor and, upon conviction of any such violation, shall be punished as provided in
Section 1- 9. In any case of a violation of any of the terms and provisions of the codes adopted
by the ordinance, by any corporation, the officers and agents actively in charge of the business
of such corporation shall be subject to the penalty provided in this section.
Local Amendments.
1. All buildings are required to be protected by an automatic fire sprinkler system. See the
Westlake Fire Code (Chapter 38) and amendments for provisions, and exceptions, relating to
the requirements for the installation of Automatic Fire Sprinkler systems.
Amendments to the 2018 International Building Code.
The following sections, paragraphs, and sentences of the 2018 International Building Code
are hereby amended as follows: Standard type is text from the IBC. Underlined type is text
inserted. Lined through type is deleted text from IBC. A double asterisk (**) at the beginning
of a section identifies an amendment carried over from the 2015 edition of the code and a
triple asterisk (***) identifies a new or revised amendment with the 2018 code.
**Section 101.4; change to read as follows:
Ordinance 888
Page 3 of 84
101.4 Referenced codes. The other codes listed in Sections 101.4.1 through 101.4.8 and
referenced elsewhere in this code, when specifically adopted, shall be considered part of the
requirements of this code to the prescribed extent of each such reference. Whenever
amendments have been adopted to the referenced codes and standards, each reference to said
code and standard shall be considered to reference the amendments as well. Any reference to
NFPA 70 or the Electrical Code shall mean the Electrical Code as adopted.
(Reason: Legal wording to recognize locally adopted codes and amendments adopted with
referenced codes. The former ICC Electrical Code is now Appendix K of this code but no longer
called by that name.)
**Section 101.4.8; add the following:
101.4.8 Electrical. The provisions of the Electrical Code shall apply to the installation of
electrical systems, including alterations, repairs, replacement, equipment, appliances, fixtures,
fittings and appurtenances thereto.
(Reason: This was dropped when ICC quit publishing the ICC Electrical Code, but the
Electrical Code still should be referenced regardless of how it is adopted.)
** Section 103 and 103.1; amend to insert the Department Name
TOWN OF WESTLAKE BUILDING INSPECTION DEPARTMENT
103.1 Creation of enforcement agency. The Town of Westlake Building Inspection
Department is hereby created and the official in charge thereof shall be known as the Building
Official.
(Reason: Reminder to be sure ordinance reads the same as designated by the city.)
***Section [A] 104.2.1 Determination of substantially improved or substantially damaged
existing buildings and structures in flood hazard areas. (Jurisdictions may consider the
option to amend or delete depending on local enforcement and flood hazard ordinances.)
(Reason: Flood hazard ordinances may be administered by other departments within the city.)
**Section 104.10.1; Flood hazard areas. (Jurisdictions may consider the option to amend or
delete depending on local enforcement and flood hazard ordinances.)
(Reason: Flood hazard ordinances may be administered by other departments within the city.)
**Section 105.2 Work exempt from permit; under sub-title entitled “Building” delete items
1, 2, 10 and 11 and re-number as follows:
Building:
Ordinance 888
Page 4 of 84
1. One-story detached accessory structures used as tool and storage sheds, playhouses and
similar uses, provided the floor area does not exceed 120 square feet (11 m2).
2. Fences not over 7 feet (1829 mm) high.
3. 1. (Remainder Unchanged)
4. 2. (Remainder Unchanged)
5. 3. (Remainder Unchanged)
6. 4. (Remainder Unchanged)
7. 5. (Remainder Unchanged)
8. 6. ( Remainder Unchanged)
9. 7. (Remainder Unchanged)
10. Shade cloth structures constructed for nursery or agricultural purposes, not including
service systems.
11. 8. (Remainder Unchanged)
12. 9. (Remainder Unchanged)
13. 10. (Remainder Unchanged)
(Reason: Items deleted are for one- and two-family dwellings regulated by the International
Residential Code. Accessory structures, fences and shade cloth structures would require a
permit for commercial properties to ensure compliance with local ordinance, egress,
accessibility, flame spread of fabric, wind/snow design load, etc.)
**Section 109; add Section 109.7 to read as follows:
109.7 Re-inspection Fee. A fee as established by city council resolution may be charged when:
1. The inspection called for is not ready when the inspector arrives;
2. No building address or permit card is clearly posted;
3. City approved plans are not on the job site available to the inspector;
4. The building is locked or work otherwise not available for inspection when called;
5. The job site is red-tagged twice for the same item;
6. The original red tag has been removed from the job site.
7. Failure to maintain erosion control, trash control or tree protection.
Any re-inspection fees assessed shall be paid before any more inspections are made on that
job site.
(Reason: This fee is not a fine or penalty but is designed to compensate for time and trips when
Ordinance 888
Page 5 of 84
inspections are called for when not ready.)
**Section 109; add Section 109.8, 109.8.1, 109.8.2 and 109.9 to read as follows:
109.8 Work without a permit.
109.8.1 Investigation. Whenever work for which a permit is required by this code has been
commenced without first obtaining a permit, a special investigation shall be made before a
permit may be issued for such work.
109.8.2 Fee. An investigation fee, in addition to the permit fee, shall be collected whether
or not a permit is subsequently issued. The investigation fee shall be equal to the amount of
the permit fee required by this code or the city fee schedule as applicable. The payment of
such investigation fee shall not exempt the applicant from compliance with all other
provisions of either this code or the technical codes nor from penalty prescribed by law.
109.9 Unauthorized cover up fee. Any work concealed without first obtaining the required
inspection in violation of Section 110 shall be assessed a fee as established by the city fee
schedule.
(Reason: This fee is not a fine or penalty but is designed to compensate for time and to remove
incentive to attempt to evade permits and code compliance. Text taken from former Uniform
Administrative Code.)
***Section 110.3.5; Lath, gypsum board and gypsum panel product inspection; Delete
exception
Exception : Gypsum board and gypsum panel products that are not part of a fire resistance
rated assembly or a shear assembly.
(Reason: Lath or gypsum board inspections are not typically performed in this area.)
***Section 202; amend definition of Ambulatory Care Facility as follows:
AMBULATORY CARE FACILITY. Buildings or portions thereof used to provide medical,
surgical, psychiatric, nursing or similar care on a less than 24-hour basis to individuals who are
rendered incapable of self-preservation by the services provided or staff has accepted
responsibility for care recipients already incapable. This group may include but not be limited
to the following:
- Dialysis centers
- Sedation dentistry
- Surgery centers
- Colonic centers
- Psychiatric centers
Ordinance 888
Page 6 of 84
(Reason: To clarify the range of uses included in the definition. [Explanatory note related to
Ambulatory Care Facilities: This group of uses includes medical or dental offices where
persons are put under for dental surgery or other services. Section 903.2.2 will now require
such uses to be sprinklered if on other than the floor of exit discharge or if four or more persons
are put under on the level of exit discharge. Recommend (1.) jurisdictions document any pre-
existing non-conforming conditions prior to issuing a new C of O for a change of tenant and,
(2.) On any medical or dental office specify on C of O the maximum number of persons
permitted to be put under general anesthesia. It is recommended that before a Certificate of
Occupancy is issued, a letter of intended use from the business owner shall be included and a
C of O documenting the maximum number of care recipients incapable of self preservation
allowed.)
**Section 202; add definition of Assisting Living Facilities to read as follows.
ASSISTED LIVING FACILITIES. A building or part thereof housing persons, on a 24-hour
basis, who because of age, mental disability or other reasons, live in a supervised residential
environment which provides personal care services. The occupants are capable of responding
to an emergency situation without physical assistance from staff.
(Reason: The code references Assisted Living facilities and definition was deleted.)
**Section 202; change definition of “Atrium” as follows:
ATRIUM. An opening connecting two three or more stories… {Balance remains unchanged}
(Reason: Accepted practice in the region based on legacy codes. Section 1019 permits
unenclosed two story stairways under certain circumstances.)
***Section 202; add amend definition of “Repair Garage” as follows:
REPAIR GARAGE. A building, structure or portion thereof used for servicing or repairing
motor vehicles. This occupancy shall also include garages involved in minor repair,
modification and servicing of motor vehicles for items such as lube changes, inspections,
windshield repair or replacement, shocks, minor part replacement and other such minor repairs.
(Reason: The code references aligns with fire code.)
**Section 202; amend definition of SPECIAL INSPECTOR to read as follows:
SPECIAL INSPECTOR. A qualified person employed or retained by an approved agency
who shall prove to the satisfaction of the registered design professional in responsible charge
and approved by the Building Official as having the competence necessary to inspect a
particular type of construction requiring special inspection.
(Reason: The registered design professional in responsible charge should be included.)
Ordinance 888
Page 7 of 84
Option B
**Section 202; amend definition to read as follows:
HIGH-RISE BUILDING. A building with an occupied floor located more than 75 55 feet
(22 860 mm) (16 764 mm) above the lowest level of fire department vehicle access.
(Reason: To define high-rise, as it influences sprinkler requirement thresholds based on the fire
fighting capabilities of a jurisdiction.)
***Section 303.1.3; add a sentence to read as follows:
303.1.3 Associated with Group E occupancies. A room or space used for assembly purposes
that is associated with a Group E occupancy is not considered a separate occupancy, Except
when applying the assembly requirements of Chapters 10 and 11.
(Reason: To clarify that egress and accessibility requirements are applicable for assembly
areas, i.e. cafeteria, auditoriums, etc.)
**Section 304.1; add the following to the list of occupancies:
Fire stations
Police stations with detention facilities for 5 or less
(Reason: Consistent with regional practice dating back to the legacy codes.)
**Section 307.1.1; add the following sentence to Exception 4:
4. Cleaning establishments… {Text unchanged} …with Section 707 or 1-hour horizontal
assemblies constructed in accordance with Section 711 or both. See also IFC Chapter 21, Dry
Cleaning Plant provisions.
(Reason: To call attention to detailed requirements in the Fire Code.)
**Section 403.1, Exception 3; change to read as follows:
3. The open air portion of a building [remainder unchanged]
(Reason: To clarify enclosed portions are not exempt.)
**Section 403.3, Exception; delete item 2.
(Reason: To provide adequate fire protection to enclosed areas.)
Ordinance 888
Page 8 of 84
**Section 403.3.2; change to read as follows:
[F] 403.3.2 Water supply to required fire pumps. In buildings that are more than 420 120
feet (36.5 m) in building height, required fire pumps shall be supplied by connections to no
fewer than two water mains located in different streets. Separate supply piping shall be provided
between each connection to the water main and the pumps. Each connection and the supply
piping between the connection and the pumps shall be sized to supply the flow and pressure
required for the pumps to operate.
Exception: {No change to exception.}
(Reason: The 2009 edition of the IFC added this requirement based on a need for redundancy
of the water supply similar to the redundancy of the power supply to the fire pumps required
for such tall buildings, partially due to the fact that these buildings are rarely fully evacuated
in a fire event. More commonly, the alarm activates on the floor of the event, the floor above
and the floor below. Back-up power to the fire pump becomes critical for this reason.
Certainly, the power is pointless if the water supply is impaired for any reason, so a similar
requirement is provided here for redundant water supplies. The 2015 edition changed the
requirement to only apply to very tall buildings over 420 ft. This amendment modifies/lowers
the requirement to 120 ft., based on this same height requirement for fire service access
elevators. Again, the language from the 2009 and 2012 editions of the code applied to any
high-rise building. This compromise at 120 ft. is based on the above technical justification of
defend-in-place scenarios in fire incidents in such tall structures.)
**Section 404.5; delete Exception.
(Reason: Consistent with amended atrium definition.)
**Section 406.3.3.1 Carport separation; add sentence to read as follows:
A fire separation is not required between a Group R-2 and U carport provided that the
carport is entirely open on all sides and that the distance between the two is at least 10
feet (3048 mm).
(Reason: Simplifies the fire separation distance and eliminates the need to obtain opening
information on existing buildings when adding carports in existing apartment complexes.
Consistent with legacy codes in effect in region for years and no record of problems with car
fires spreading to apartments as a result.)
***Table 506.2; delete sentence from table
I. The maximum allowable area for a single-story non sprinklered Group U greenhouse is
permitted to be 9000 square feet or the allowable area shall be permitted to comply with Table
C102.1 of Appendix C.
Ordinance 888
Page 9 of 84
(Reason: To eliminate the need for Appendix C adoption and remain consistent with 6000 sq.
ft. sprinklering provision.)
**Section 506.3.1; add sentence to read as follows:
506.3.1 Minimum percentage of perimeter. [Existing Text remains]
In order to be considered as accessible, if not in direct contact with a street or fire lane, a
minimum 10-foot wide pathway meeting fire department access from the street or approved fire
lane shall be provided.
(Reason: To define what is considered accessible. Consistent with regional amendment to IFC
504.1.)
***Section 602.1.1; add sentence to read as follows:
602.1.1 Minimum Requirements. [Existing Text to remain]
Where a building contains more than one distinct type of construction, the building shall comply
with the most restrictive area, height, and stories, for the lesser type of construction or be
separated by fire walls.
(Reason: To create definite language that requires separation between dissimilar building
types.)
***Section 708.4.2; change sentence to read as follows:
708.4.2 Fireblocks and draftstops in combustible construction. [Body of text unchanged]
Exceptions:
1. Buildings equipped with an automatic sprinkler system installed throughout in
accordance with Section 903.3.1.1, or in accordance with Section 903.3.1.2
provided that sprinkler protection is provided in the space between the top of the
fire partition and the underside of the floor or roof sheathing, deck or slab above as
required for systems complying with Section 903.3.1.1. Portions of buildings
containing concealed spaces filled with noncombustible insulation as permitted for
sprinkler omission shall not apply to this exception for draftstopping.
[Remainder unchanged]
Reason: (The most common exception used to eliminate the need for sprinklers in concealed
spaces of combustible construction is to fill the space with noncombustible insulation. This
exception was changed in 2010 to permit a 2-inch air gap at the top of the filled space. A space
compliant with the permitted omission above would allow hot gas and smoke to spread
unimpeded throughout a building not provided with draftstopping. For this reason, omission of
sprinklers permitted in accordance with NFPA 13 referenced standard should not be permitted
with IBC exception requiring draftstopping in combustible construction.)
Ordinance 888
Page 10 of 84
***Section 718.3; change sentence to read as follows:
718.3 Draftstopping in floors. [Body of text unchanged]
Exceptions: Buildings equipped throughout with an automatic sprinkler system in
accordance with Section 903.3.1.1. and provided that in combustible construction,
sprinkler protection is provided in the floor space.
(Reason: To remain consistent with changes in 708.4.2 code.)
***Section 718.4; change sentence to read as follows:
718.4 Draftstopping in attics. [Body of text unchanged]
Exceptions: Buildings equipped throughout with an automatic sprinkler system in
accordance with Section 903.3.1.1 and provided that in combustible construction,
sprinkler protection is provided in the attic space.
(Reason: To remain consistent with changes in 708.4.2 code.)
**Section 901.6.1; add Section 901.6.1.1 to read as follows:
901.6.1.1 Standpipe Testing. Building owners/managers must maintain and test standpipe
systems as per NFPA 25 requirements. The following additional requirements shall be applied
to the testing that is required every 5 years:
1. The piping between the Fire Department Connection (FDC) and the standpipe shall be
backflushed or inspected by approved camera when foreign material is present or when
caps are missing, and also hydrostatically tested for all FDC’s on any type of standpipe
system. Hydrostatic testing shall also be conducted in accordance with NFPA 25
requirements for the different types of standpipe systems.
2. For any manual (dry or wet) standpipe system not having an automatic water supply
capable of flowing water through the standpipe, the tester shall connect hose from a fire
hydrant or portable pumping system (as approved by the fire code official) to each FDC,
and flow water through the standpipe system to the roof outlet to verify that each inlet
connection functions properly. Confirm that there are no open hose valves prior to
introducing water into a dry standpipe. There is no required pressure criteria at the outlet.
Verify that check valves function properly and that there are no closed control valves on
the system.
3. Any pressure relief, reducing, or control valves shall be tested in accordance with the
requirements of NFPA 25. All hose valves shall be exercised.
4. If the FDC is not already provided with approved caps, the contractor shall install such
caps for all FDC’s as required by the fire code official.
Ordinance 888
Page 11 of 84
5. Upon successful completion of standpipe test, place a blue tag (as per Texas
Administrative Code, Fire Sprinkler Rules for Inspection, Test and Maintenance Service
(ITM) Tag) at the bottom of each standpipe riser in the building. The tag shall be check-
marked as “Fifth Year” for Type of ITM, and the note on the back of the tag shall read “5
Year Standpipe Test” at a minimum.
6. The procedures required by Texas Administrative Code Fire Sprinkler Rules with regard
to Yellow Tags and Red Tags or any deficiencies noted during the testing, including the
required notification of the local Authority Having Jurisdiction (fire code official) shall
be followed.
7. Additionally, records of the testing shall be maintained by the owner and contractor, if
applicable, as required by the State Rules mentioned above and NFPA 25.
8. Standpipe system tests where water will be flowed external to the building shall not be
conducted during freezing conditions or during the day prior to expected night time
freezing conditions.
9. Contact the fire code official for requests to remove existing fire hose from Class II and
III standpipe systems where employees are not trained in the utilization of this firefighting
equipment. All standpipe hose valves must remain in place and be provided with an
approved cap and chain when approval is given to remove hose by the fire code official.
(Reason: Increases the reliability of the fire protection system and re-emphasizes the
requirements of NFPA 25 relative to standpipe systems, as well as ensuring that FDC
connections are similarly tested/maintained to ensure operation in an emergency incident.)
**Section 903.1.1; change to read as follows:
903.1.1 Alternative Protection. Alternative automatic fire-extinguishing systems complying
with Section 904 shall be permitted instead of in addition to automatic sprinkler protection
where recognized by the applicable standard and, or as approved by the fire code official.
(Reason: Such alternative systems do not provide the reliability of automatic sprinkler
protection. Most gaseous type systems are highly susceptible to open doors, ceiling or floor
tile removal, etc. However, an applicant could pursue an Alternate Method request to help
mitigate the reliability issues with these alternative systems with the fire code official if so
desired, or there may be circumstances in which the fire code official is acceptable to allowing
an alternate system in lieu of sprinklers, such as kitchen hoods or paint booths.)
**Section 903.2; add paragraph to read as follows and delete the exception:
Automatic Sprinklers shall not be installed in elevator machine rooms, elevator machine spaces,
and elevator hoistways, other than pits where such sprinklers would not necessitate shunt trip
requirements under any circumstances. Storage shall not be allowed within the elevator
Ordinance 888
Page 12 of 84
machine room. Signage shall be provided at the entry doors to the elevator machine room
indicating “ELEVATOR MACHINERY – NO STORAGE ALLOWED.”
(Reason: Firefighter and public safety. This amendment eliminates the shunt trip requirement
of the International Building Code Section 3005.5 for the purpose of elevator passenger and
firefighter safety. This amendment is contingent on the Building Code amendment eliminating
the Exceptions to Section 3005.4, such that passive fire barriers for these areas are maintained.
The exception deletion is due to the fact that such telecom areas pose an undue fire risk to the
structural integrity of the building.)
**Section 903.2.9; add Section 903.2.9.3 to read as follows:
903.2.9.3 Self-Service Storage Facility. An automatic sprinkler system shall be installed
throughout all self-service storage facilities.
(Reason: Fire departments are unable to inspect these commercial occupancies and are
unaware of the contents being stored. Previous allowance to separate units by fire barriers is
difficult to enforce maintenance after opening.)
**Option B
Section 903.2.11; change 903.2.11.3 and add 903.2.11.7, 903.2.11.8, and 903.2.11.9 as
follows:
903.2.11.3 Buildings 55 35 feet or more in height. An automatic sprinkler system shall
be installed throughout buildings that have one or more stories with an occupant load of 30
or more, other than penthouses in compliance with Section 1510 of the International
Building Code, located 55 35 feet (16 764 10 668 mm) or more above the lowest level of
fire department vehicle access, measured to the finished floor.
Exceptions:
1. Open parking structures in compliance with Section 406.5 of the International
Building Code, having no other occupancies above the subject garage.
2. Occupancies in Group F-2.
903.2.11.7 High-Piled Combustible Storage. For any building with a clear height
exceeding 12 feet (4572 mm), see Chapter 32 to determine if those provisions apply.
903.2.11.8 Spray Booths and Rooms. New and existing spray booths and spraying rooms
shall be protected by an approved automatic fire-extinguishing system.
903.2.11.9 Buildings Over 6,000 sq. ft. An automatic sprinkler system shall be installed
throughout all buildings with a building area 6,000 sq. ft. or greater and in all existing
buildings that are enlarged to be 6,000 sq. ft. or greater. For the purpose of this provision,
fire walls shall not define separate buildings.
Exception: Open parking garages in compliance with Section 406.5 of the International
Building Code.
Ordinance 888
Page 13 of 84
(Reason: Provides jurisdictions options as to their desired level of sprinkler protection based
on multiple factors including firefighting philosophies/capabilities.)
**Section 903.3.1.1.1; change to read as follows:
903.3.1.1.1 Exempt Locations. When approved by the fire code official, automatic sprinklers
shall not be required in the following rooms or areas where such ...{text unchanged}… because
it is damp, of fire-resistance-rated construction or contains electrical equipment.
1. Any room where the application of water, or flame and water, constitutes a serious life
or fire hazard.
2. Any room or space where sprinklers are considered undesirable because of the nature
of the contents, when approved by the fire code official.
3. Generator and transformer rooms, under the direct control of a public utility, separated
from the remainder of the building by walls and floor/ceiling or roof/ceiling assemblies
having a fire-resistance rating of not less than 2 hours.
4. In rooms or areas that are of noncombustible construction with wholly noncombustible
contents.
5. Fire service access Elevator machine rooms, and machinery spaces, and hoistways,
other than pits where such sprinklers would not necessitate shunt trip requirements
under any circumstances.
6. {Delete.}
(Reason: Gives clarification. Exception 4 deleted to provide protection where fire risks are
poorly addressed. Amendment 903.2 addresses Exception 5 above relative to the elimination
of sprinkler protection in these areas to avoid the shunt trip requirement.)
***Section 903.3.1.2.3; delete sections and replace as follows:
[F] Section 903.3.1.2.3 Attached Garages and Attics. Sprinkler protection is required in
attached garages, and in the following attic spaces:
1. [Remainder Unchanged]
2. [Remainder Unchanged]
3. Attic spaces of buildings that are two or more stories in height above grade plane or
above the lowest level of fire department vehicle access.
4. Group R-4, Condition 2 occupancy attics not required by Item 1 or 3 to have
sprinklers shall comply with one of the following:
[Remainder Unchanged]
(Reason: Attic protection is required due to issues with fire exposure via soffit vents, as well as
firefighter safety. Several jurisdictions indicated experience with un-protected attic fires
resulting in displacement of all building occupants. NFPA 13 provides for applicable attic
Ordinance 888
Page 14 of 84
sprinkler protection requirements, as well as exemptions to such, based on noncombustible
construction, etc. Attached garages already require sprinklers via NFPA 13R – this amendment
just re-emphasizes the requirement.)
**Section 903.3.1.3; change to read as follows:
903.3.1.3 NFPA 13D Sprinkler Systems. Automatic sprinkler systems installed in one- and
two-family dwellings; Group R-3; Group R-4, Condition 1; and townhouses shall be permitted
to be installed throughout in accordance with NFPA 13D or in accordance with state law.
(Reason: To allow the use of the Plumbing section of the International Residential Code (IRC)
and recognize current state stipulations in this regard.)
**Section 903.3.1.4; add to read as follows:
[F] 903.3.1.4 Freeze protection. Freeze protection systems for automatic fire sprinkler systems
shall be in accordance with the requirements of the applicable referenced NFPA standard and
this section.
903.3.1.4.1 Attics. Only dry-pipe, preaction, or listed antifreeze automatic fire sprinkler
systems shall be allowed to protect attic spaces.
Exception: Wet-pipe fire sprinkler systems shall be allowed to protect non-
ventilated attic spaces where:
1. The attic sprinklers are supplied by a separate floor control valve
assembly to allow ease of draining the attic system without impairing
sprinklers throughout the rest of the building, and
2. Adequate heat shall be provided for freeze protection as per the
applicable referenced NFPA standard, and
3. The attic space is a part of the building’s thermal, or heat, envelope, such
that insulation is provided at the roof deck, rather than at the ceiling level.
903.3.1.4.2 Heat trace/insulation. Heat trace/insulation shall only be allowed where
approved by the fire code official for small sections of large diameter water-filled pipe.
(Reason: In the last few years, severe winters brought to light several issues with current
practices for sprinklering attics, not the least of which was wet-pipe sprinklers in ventilated
attics provided with space heaters, etc. for freeze protection of such piping. This practice is
not acceptable for the protection of water-filled piping in a ventilated attic space as it does not
provide a reliable means of maintaining the minimum 40 degrees required by NFPA, wastes
energy, and presents a potential ignition source to the attic space. Listed antifreeze is
specifically included because NFPA currently allows such even though there is no currently
listed antifreeze at the time of development of these amendments. The intent of this amendment
is to help reduce the large number of freeze breaks that have occurred in the past with water-
filled wet-pipe sprinkler systems in the future, most specifically in attic spaces.)
Ordinance 888
Page 15 of 84
**Section 903.3.5; add a second paragraph to read as follows:
Water supply as required for such systems shall be provided in conformance with the supply
requirements of the respective standards; however, every water-based fire protection system
shall be designed with a 10 psi safety factor. Reference Section 507.4 for additional design
requirements.
(Reason: To define uniform safety factor for the region.)
**Section 903.4; add a second paragraph after the exceptions to read as follows:
Sprinkler and standpipe system water-flow detectors shall be provided for each floor tap to the
sprinkler system and shall cause an alarm upon detection of water flow for more than 45
seconds. All control valves in the sprinkler and standpipe systems except for fire department
hose connection valves shall be electrically supervised to initiate a supervisory signal at the
central station upon tampering.
(Reason: To avoid significant water losses. Consistent with amendment to IFC 905.9.)
**Section 903.4.2; add second paragraph to read as follows:
The alarm device required on the exterior of the building shall be a weatherproof horn/strobe
notification appliance with a minimum 75 candela strobe rating, installed as close as practicable
to the fire department connection.
(Reason: Fire department connections are not always located at the riser; this allows the fire
department faster access.)
**Section 905.2; change to read as follows:
905.2 Installation Standard. Standpipe systems shall be installed in accordance with this
section and NFPA 14. Manual dry standpipe systems shall be supervised with a minimum of
10 psig and a maximum of 40 psig air pressure with a high/low alarm.
(Reason: To define manual dry standpipe supervision requirements. Helps ensure the integrity
of the standpipe system via supervision, such that open hose valves will result in a supervisory
low air alarm.)
***Section 905.3; add Section 905.3.9 and exception to read as follows:
905.3.9 Buildings Exceeding 10,000 sq. ft. In buildings exceeding 10,000 square feet in area
per story and where any portion of the building’s interior area is more than 200 feet (60960
mm) of travel, vertically and horizontally, from the nearest point of fire department vehicle
access, Class I automatic wet or manual wet standpipes shall be provided.
Ordinance 888
Page 16 of 84
Exceptions:
1. Automatic dry, semi-automatic dry, and manual dry standpipes are allowed as
provided for in NFPA 14 where approved by the fire code official.
2. R-2 occupancies of four stories or less in height having no interior corridors.
(Reason: Allows for the rapid deployment of hose lines to the body of the fire. Manual dry
option added this edition.)
**Section 905.4, change Item 1, 3, and 5, and add Item 7 to read as follows:
1. In every required interior exit stairway, a hose connection shall be provided for each
story above and below grade plane. Hose connections shall be located at the main floor
landing between stories, unless otherwise approved by the fire code official.
2. {No change.}
3. In every exit passageway, at the entrance from the exit passageway to other areas of a
building.
Exception: Where floor areas adjacent to an exit passageway are reachable from an interior
exit stairway hose connection by a {No change to rest.}
4. {No change.}
5. Where the roof has a slope less than four units vertical in 12 units horizontal (33.3-
percent slope), each standpipe shall be provided with a two-way a hose connection shall
be located to serve the roof or at the highest landing of an interior exit stairway with stair
access to the roof provided in accordance with Section 1011.12.
6. {No change.}
7. When required by this Chapter, standpipe connections shall be placed adjacent to all
required exits to the structure and at two hundred feet (200’) intervals along major
corridors thereafter, or as otherwise approved by the fire code official.
(Reason: Item 1, 3, and 5 amendments to remove ‘interior’ will help to clarify that such
connections are required for all ‘exit’ stairways, to ensure firefighter capabilities are not
diminished in these tall buildings, simply because the stair is on the exterior of the building.
Item 5 reduces the amount of pressure required to facilitate testing, and provides backup
protection for fire fighter safety. Item 7 allows for the rapid deployment of hose lines to the
body of the fire.)
**Section 905.9; add a second paragraph after the exceptions to read as follows:
Sprinkler and standpipe system water-flow detectors shall be provided for each floor tap to the
sprinkler system and shall cause an alarm upon detection of water flow for more than 45
seconds. All control valves in the sprinkler and standpipe systems except for fire department
Ordinance 888
Page 17 of 84
hose connection valves shall be electrically supervised to initiate a supervisory signal at the
central station upon tampering.
(Reason: To avoid significant water losses. Consistent with amendment to IFC 903.4.)
**Section 907.1; add Section 907.1.4 to read as follows:
907.1.4 Design Standards. Where a new fire alarm system is installed, the devices shall be
addressable. Fire alarm systems utilizing more than 20 smoke detectors shall have analog
initiating devices.
(Reason: Provides for the ability of descriptive identification of alarms, and reduces need for
panel replacement in the future. Updated wording to match the language of the new
requirement at 907.5.2.3. Change of terminology allows for reference back to definitions of
NFPA 72.)
**Section 907.2.1; change to read as follows:
907.2.1 Group A. A manual fire alarm system that activates the occupant notification system
in accordance with Section 907.5 shall be installed in Group A occupancies where the having
an occupant load due to the assembly occupancy is of 300 or more persons, or where the Group
A occupant load is more than 100 persons above or below the lowest level of exit discharge.
Group A occupancies not separated from one another in accordance with Section 707.3.10 of
the International Building Code shall be considered as a single occupancy for the purposes of
applying this section. Portions of Group E occupancies occupied for assembly purposes shall
be provided with a fire alarm system as required for the Group E occupancy.
Exception: {No change.}
Activation of fire alarm notification appliances shall:
1. Cause illumination of the means of egress with light of not less than 1 foot-candle (11
lux) at the walking surface level, and
2. Stop any conflicting or confusing sounds and visual distractions.
(Reason: Increases the requirement to be consistent with Group B requirement. Also addresses
issue found in Group A occupancies of reduced lighting levels and other A/V equipment that
distracts from fire alarm notification devices or reduces ability of fire alarm system to notify
occupants of the emergency condition.)
**Section 907.2.3; change to read as follows:
907.2.3 Group E. A manual fire alarm system that initiates the occupant notification signal
utilizing an emergency voice/alarm communication system meeting the requirements of Section
907.5.2.2 and installed in accordance with Section 907.6 shall be installed in Group E
educational occupancies. When automatic sprinkler systems or smoke detectors are installed,
such systems or detectors shall be connected to the building fire alarm system. An approved
Ordinance 888
Page 18 of 84
smoke detection system shall be installed in Group E day care occupancies. Unless separated
by a minimum of 100' open space, all buildings, whether portable buildings or the main
building, will be considered one building for alarm occupant load consideration and
interconnection of alarm systems.
Exceptions:
1. {No change.}
1.1.Residential In-Home day care with not more than 12 children may use
interconnected single station detectors in all habitable rooms. (For care of more
than five children 2 1/2 or less years of age, see Section 907.2.6.) {No change
to remainder of exceptions.}
(Reason: To distinguish educational from day care occupancy minimum protection
requirements. Further, to define threshold at which portable buildings are considered a
separate building for the purposes of alarm systems. Exceptions provide consistency with State
law concerning such occupancies.)
**Section 907.2.12, Exception 3; change to read as follows:
3. Open air portions of buildings with an occupancy in Group A-5 in accordance with Section
303.1 of the International Building Code; however, this exception does not apply to
accessory uses including but not limited to sky boxes, restaurants, and similarly enclosed
areas.
(Reason: To indicate that enclosed areas within open air seating type occupancies are not
exempted from automatic fire alarm system requirements.)
**Section 907.4.2; add Section 907.4.2.7 to read as follows:
907.4.2.7 Type. Manual alarm initiating devices shall be an approved double action type.
(Reason: Helps to reduce false alarms.)
**Section 907.6.1; add Section 907.6.1.1 to read as follows:
907.6.1.1 Wiring Installation. All fire alarm systems shall be installed in such a manner that
a failure of any single initiating device or single open in an initiating circuit conductor will not
interfere with the normal operation of other such devices. All signaling line circuits (SLC) shall
be installed in such a way that a single open will not interfere with the operation of any
addressable devices (Class A). Outgoing and return SLC conductors shall be installed in
accordance with NFPA 72 requirements for Class A circuits and shall have a minimum of four
feet separation horizontal and one foot vertical between supply and return circuit
conductors. The initiating device circuit (IDC) from a signaling line circuit interface device
may be wired Class B, provided the distance from the interface device to the initiating device
is ten feet or less.
Ordinance 888
Page 19 of 84
(Reason: To provide uniformity in system specifications and guidance to design engineers.
Improves reliability of fire alarm devices and systems.)
**Section 907.6.3; delete all four Exceptions.
(Reason: To assist responding personnel in locating the emergency event for all fire alarm
systems.)
**Section 907.6.6; add sentence at end of paragraph to read as follows:
See 907.6.3 for the required information transmitted to the supervising station.
(Reason: To assist responding personnel in locating the emergency event for all fire alarm
systems.)
(Reason: Deleted Previous code amendment Section 909.22, For removal because it is already
in the code in Sections 909.20.5, 909.20.6, 909.20.6.1, 909.20.6.2, and 909.20.6.3.)
**Section 910.2; change Exception 2 and 3 to read as follows:
2. Only manual smoke and heat removal shall not be required in areas of buildings
equipped with early suppression fast-response (ESFR) sprinklers. Automatic smoke and
heat removal is prohibited.
3. Only manual smoke and heat removal shall not be required in areas of buildings
equipped with control mode special application sprinklers with a response time index
of 50(m*S)1/2 or less that are listed to control a fire in stored commodities with 12 or
fewer sprinklers. Automatic smoke and heat removal is prohibited.
(Reason: Allows the fire department to control the smoke and heat during and after a fire event,
while still prohibiting such systems from being automatically activated, which is a potential
detriment to the particular sprinkler systems indicated.)
**Section 910.2; add subsections 910.2.3 with exceptions to read as follows:
910.2.3 Group H. Buildings and portions thereof used as a Group H occupancy as follows:
1. In occupancies classified as Group H-2 or H-3, any of which are more than 15,000
square feet (1394 m2) in single floor area.
Exception: Buildings of noncombustible construction containing only noncombustible
materials.
2. In areas of buildings in Group H used for storing Class 2, 3, and 4 liquid and solid
oxidizers, Class 1 and unclassified detonable organic peroxides, Class 3 and 4 unstable
(reactive) materials, or Class 2 or 3 water-reactive materials as required for a high-
hazard commodity classification.
Ordinance 888
Page 20 of 84
Exception: Buildings of noncombustible construction containing only noncombustible
materials.
(Reason: Maintains a fire protection device utilized in such occupancies where it is sometimes
necessary to allow chemicals to burn out, rather than extinguish.)
**Section 910.3; add section 910.3.4 to read as follows:
910.3.4 Vent Operation. Smoke and heat vents shall be capable of being operated by approved
automatic and manual means. Automatic operation of smoke and heat vents shall conform to
the provisions of Sections 910.3.2.1 through 910.3.2.3.
910.3.4.1 Sprinklered buildings. Where installed in buildings equipped with an approved
automatic sprinkler system, smoke and heat vents shall be designed to operate automatically.
The automatic operating mechanism of the smoke and heat vents shall operate at a temperature
rating at least 100 degrees F (approximately 38 degrees Celsius) greater than the temperature
rating of the sprinklers installed.
Exception: Manual only systems per Section 910.2.
910.3.4.2 Nonsprinklered Buildings. Where installed in buildings not equipped with an
approved automatic sprinkler system, smoke and heat vents shall operate automatically by
actuation of a heat-responsive device rated at between 100°F (56°C) and 220°F (122°C) above
ambient.
Exception: Listed gravity-operated drop out vents.
(Reason: Amendment continues to keep applicable wording from prior to the 2012 edition of
the IFC. Specifically, automatic activation criteria is no longer specifically required in the
published code. Specifying a temperature range at which smoke and heat vents should activate
in sprinklered buildings helps to ensure that the sprinkler system has an opportunity to activate
and control the fire prior to vent operation.)
**Section 910.4.3.1; change to read as follows:
910.4.3.1 Makeup Air. Makeup air openings shall be provided within 6 feet (1829 mm) of the
floor level. Operation of makeup air openings shall be manual or automatic. The minimum
gross area of makeup air inlets shall be 8 square feet per 1,000 cubic feet per minute (0.74 m2
per 0.4719 m3/s) of smoke exhaust.
(Reason: Makeup air has been required to be automatic for several years now in this region
when mechanical smoke exhaust systems are proposed. This allows such systems to be
activated from the smoke control panel by first responders without having to physically go
around the exterior of the building opening doors manually. Such requires a significant
number of first responders on scene to conduct this operation and significantly delays
Ordinance 888
Page 21 of 84
activation and/or capability of the smoke exhaust system.)
**Section 912.2; add Section 912.2.3 to read as follows:
912.2.3 Hydrant Distance. An approved fire hydrant shall be located within 100 feet of the
fire department connection as the fire hose lays along an unobstructed path.
(Reason: To accommodate limited hose lengths, improve response times where the FDC is
needed to achieve fire control, and improve ease of locating a fire hydrant in those situations
also. Also, consistent with NFPA 14 criteria.)
***Section 913.2.1; add Section 913.2.1.1 and exception to read as follows:
913.2.1.1 Fire Pump Room Access. When located on the ground level at an exterior wall, the
fire pump room shall be provided with an exterior fire department access door that is not less
than 3 ft. in width and 6 ft. – 8 in. in height, regardless of any interior doors that are provided. A
key box shall be provided at this door, as required by IFC Section 506.1.
Exception: When it is necessary to locate the fire pump room on other levels or not at an
exterior wall, the corridor leading to the fire pump room access from the exterior of the
building shall be provided with equivalent fire resistance as that required for the pump
room, or as approved by the fire code official. Access keys shall be provided in the key box
as required by IFC Section 506.1.
(Reason: This requirement allows fire fighters safer access to the fire pump room. The
requirement allows access without being required to enter the building and locate the fire pump
room interior access door during a fire event. The exception recognizes that this will not always
be a feasible design scenario for some buildings, and as such, provides an acceptable
alternative to protect the pathway to the fire pump room.)
**Section 1006.2.2.7; add Section 1006.2.2.7 as follows:
1006.2.2.7 Electrical Rooms. For electrical rooms, special exiting requirements may apply.
Reference the electrical code as adopted.
(Reason: Cross reference necessary for coordination with the NEC which has exiting
requirements as well.)
**Section 1009.8; add the following Exception 7:
1009.8 Two Way Communication. A two-way communication system complying with
Sections 1009.8.1 and 1009.8.2 shall be provided at the landing serving each elevator required
to be accessible on each accessible floor that is one or more stories above or below the level of
exit discharge.
Ordinance 888
Page 22 of 84
Exceptions:
7. Buildings regulated under State Law and built in accordance with State registered plans,
including variances or waivers granted by the State, shall be deemed to be in compliance with
the requirements of Section 1009 and chapter 11.
(Reason: To accommodate buildings regulated under Texas State Law and to be consistent with
amendments in Chapter 11.)
**Section 1010.1.9.5 Bolt Locks; amend exceptions 3 and 4 as follows:
Exceptions:
3. Where a pair of doors serves an occupant load of less than 50 persons in a Group B, F, M or
S occupancy. (remainder unchanged)
4. Where a pair of doors serves a Group A, B, F, M or S occupancy (remainder unchanged)
(Reason: Application to M occupancies reflects regional practice; No. 4 expanded to Group A
due to it being a similar scenario to other uses; No. 4 was regional practice.)
**Section 1020.1 Construction; add exception 6 to read as follows:
6. In group B occupancies, corridor walls and ceilings need not be of fire-resistive construction
within a single tenant space when the space is equipped with approved automatic smoke-
detection within the corridor. The actuation of any detector must activate self-annunciating
alarms audible in all areas within the corridor. Smoke detectors must be connected to an
approved automatic fire alarm system where such system is provided.
(Reason: Regionally accepted alternate method.)
**Section 1029.1.1.1 Spaces under grandstands and bleachers; delete this section.
(Reason: Unenforceable.)
**Section 1101.1 Scope; add exception to Section 1101.1 as follows:
Exception: Components of projects regulated by and registered with Architectural Barriers
Division of Texas Department of Licensing and Regulation shall be deemed to be in compliance
with the requirements of this chapter.
(Reason: To accommodate buildings regulated under state law. Further clarified in 2015 to
mean components that are specifically addressed by TDLR shall be exempt.)
**Section 2901.1; add a sentence to read as follows:
[P] 2901.1 Scope. {existing text to remain} The provisions of this Chapter are meant to work
in coordination with the provisions of Chapter 4 of the International Plumbing Code. Should
Ordinance 888
Page 23 of 84
any conflicts arise between the two chapters, the Building Official shall determine which
provision applies.
(Reason: Gives building official discretion.)
**Section 2902.1; add a second paragraph to read as follows:
In other than E Occupancies, the minimum number of fixtures in Table 2902.1 may be lowered,
if requested in writing, by the applicant stating reasons for a reduced number and approved by
the Building Official.
(Reason: To allow flexibility for designer to consider specific occupancy needs.)
**Table 2902.1; add footnote g to read as follows:
g. Drinking fountains are not required in M Occupancies with an occupant load of 100 or less,
B Occupancies with an occupant load of 25 or less, and for dining and/or drinking
establishments.
(Reason: Adjustment meets the needs of specific occupancy types.)
**Add new Section 2902.1.4 to read as follows:
2902.1.4 Additional fixtures for food preparation facilities. In addition to the fixtures
required in this Chapter, all food service facilities shall be provided with additional fixtures set
out in this section.
2902.1.4.1 Hand washing lavatory. At least one hand washing lavatory shall be provided for
use by employees that is accessible from food preparation, food dispensing and ware washing
areas. Additional hand washing lavatories may be required based on convenience of use by
employees.
2902.1.4.2 Service sink. In new or remodeled food service establishments, at least one service
sink or one floor sink shall be provided so that it is conveniently located for the cleaning of
mops or similar wet floor cleaning tool and for the disposal of mop water and similar liquid
waste. The location of the service sink(s) and/or mop sink(s) shall be approved by the
<Jurisdiction’s> health department.
(Reason: Coordinates Health law requirements with code language for consistent regional
practice.)
***Section 3001.2 Emergency Elevator Communication Systems for the deaf, hard of
hearing and speech impaired; delete this section.
Ordinance 888
Page 24 of 84
(Reason: Per Elevator manufacturers input, they were not consulted prior to code approval
and technology of elevator provisions as submitted are not currently available to provide this
feature.)
***Section 3002.1 Hoistway Enclosure Protection required. Add exceptions to Section
3002.1 as follows:
Exceptions:
4. Elevators completely located within atriums shall not require hoistway enclosure
protection.
5. Elevators in open or enclosed parking garages that serve only the parking garage, shall
not require hoistway enclosure protection.
(Reason: Provides specific Code recognition that elevators within atriums and within parking
garages do not require hoistway enclosure protection. Amendment needed since specific Code
language does not currently exist.)
**Section 3005.4 Machine rooms, control rooms, machinery spaces and control spaces;
delete text as follows:
Elevator machine rooms, control rooms, control spaces and machinery spaces outside of but
attached to a hoistway that have openings into the hoistway shall be enclosed with fire barriers
constructed in accordance with Section 707 or horizontal assemblies constructed in accordance
with Section 711, or both.
Revise text to read:
Elevator machine rooms, control rooms, control spaces and machinery spaces shall be enclosed
with fire barriers constructed in accordance with Section 707 or horizontal assemblies
constructed in accordance with Section 711, or both.
(Remainder unchanged)
(Reason: This amendment eliminates code language to be consistent with the regional goal to
require passive enclosures of these areas unless a hoistway enclosure is not required by other
Code provisions. See companion change to eliminate fire sprinklers thereby eliminating shunt
trip.)
***Section 3005.4 Machine rooms, control rooms, machinery spaces and control spaces;
Delete exceptions and add two new exceptions to Section 3005.4 as follows:
Ordinance 888
Page 25 of 84
Exceptions:
1. Elevator machine rooms, control rooms, machinery spaces and control spaces
completely located within atriums shall not require enclosure protection.
2. Elevator machine rooms, control rooms, machinery spaces and control spaces in open
or enclosed parking garages that serve only the parking garage, shall not require
enclosure protection.
(Reason: This amendment eliminates the Exceptions to Section 3005.4 such that passive
enclosures for these areas are to be provided and maintained. The fire rating of these
enclosures is permitted to be omitted by the above added exceptions where allowed by other
provisions of the code such as in atriums and parking structures. See companion change to
eliminate fire sprinklers to eliminate the need for shunt trip system.)
**Section 3005.7 add a Section 3005.7 as follows:
3005.7 Fire Protection in Machine rooms, control rooms, machinery spaces and control
spaces.
3005.7.1 Automatic sprinkler system. The building shall be equipped throughout with an
automatic sprinkler system in accordance with Section 903.3.1.1, except as otherwise permitted
by Section 903.3.1.1.1 and as prohibited by Section 3005.7.2.1.
3005.7.2.1 Prohibited locations. Automatic sprinklers shall not be installed in machine rooms,
elevator machinery spaces, control rooms, control spaces and elevator hoistways.
3005.7.2.2 Sprinkler system monitoring. The sprinkler system shall have a sprinkler control
valve supervisory switch and water-flow initiating device provided for each floor that is
monitored by the building’s fire alarm system.
3005.7.3 Water protection. An approved method to prevent water from infiltrating into the
hoistway enclosure from the operation of the automatic sprinkler system outside the elevator
lobby shall be provided.
3005.7.4 Shunt trip. Means for elevator shutdown in accordance with Section 3005.5 shall not
be installed.
(Reason: Firefighter and public safety. This amendment eliminates the shunt trip requirement
of the International Building Code Section 3005.5 for the purpose of elevator passenger and
firefighter safety. The new section above is intended to be identical to Sections 3007.2, 3007.3,
and 3007.4 for Fire Service Access Elevators and Sections 3008.2, 3008.3 and 3008.4 for
Occupant Evacuation Elevators.)
**Section 3005.8; add Section 3005.8 as follows:
Ordinance 888
Page 26 of 84
3005.8 Storage. Storage shall not be allowed within the elevator machine room, control room,
machinery spaces and or control spaces. Provide approved signage at each entry to the above
listed locations stating: "No Storage Allowed.
(Reason: Reinforces the need to maintain space clean and free of combustibles. See companion
change to eliminate fire sprinklers therein, to always require an enclosure - with IBC 3005.4
exceptions deleted - resulting in the limited need for a shunt trip system.)
Option B
Section 3006.2, Hoistway opening protection required; Revise text as follows:
5. The building is a high rise and the elevator hoistway is more than 75 feet (22 860 mm) 55
feet (16 764 mm) in height. The height of the hoistway shall be measured from the lowest floor
at or above grade to the highest floors served by the hoistway.”
(Reason: 2018 IBC text does not address hoistways that are greater than 75’-0” in height that
are both below grade and above grade but not located above the high rise classification nor
does the IBC address hoistways wholly located above grade such as those that serve sky
lobbies".)
Amendments to the 2018 International Residential Code.
The following sections, paragraphs, and sentences of the 2018 International Residential Code
are hereby amended as follows: Standard type is text from the IRC. Underlined type is text
inserted. Lined through type is deleted text from IRC. A double asterisk (**) at the beginning
of a section identifies an amendment carried over from the 2015 edition of the code and a triple
asterisk (***) identifies a new or revised amendment with the 2018 code.
The energy provisions in IRC Chapter 11 is deleted in its entirety.

**Section R102.4; change to read as follows:
R102.4 Referenced codes and standards. The codes, when specifically adopted, and
standards referenced in this code shall be considered part of the requirements of this code to the
prescribed extent of each such reference and as further regulated in Sections R102.4.1 and
R102.4.2. Whenever amendments have been adopted to the referenced codes and standards,
each reference to said code and standard shall be considered to reference the amendments as
well. Any reference made to NFPA 70 or the Electrical Code shall mean the Electrical Code
as adopted.
Ordinance 888
Page 27 of 84
(Reason: Legal wording to recognize locally adopted codes and amendments adopted with
referenced codes.)
** Section R103 and R103.1 amend to insert the Department Name
TOWN OF WESTLAKE BUILDING INSPECTION DEPARTMENT
R103.1 Creation of enforcement agency. The Town of Westlake Building Inspection
Department is hereby created and the official in charge thereof shall be known as the Building
Official.
(Reason: Reminder to be sure ordinance reads the same as designated by the city.)
**Section R104.10.1 Flood Hazard areas; delete this section.
(Reason: Flood hazard ordinances may be administered by other departments within the city.)
**Section R105.3.1.1& R106.1.4; delete these sections.
(Reason: Floodplain provisions are addressed locally.)
**Section R110 (R110.1 through R110.5); delete the section.
(Reason: Issuing CO's for residences is not a common practice in the area.)
**Section R202; change definition of "Townhouse" to read as follows:
TOWNHOUSE. A single-family dwelling unit constructed in a group of three or more
attached units separated by property lines in which each unit extends from foundation to roof
and with a yard or public way on at least two sides.
(Reason: To distinguish Townhouses on separate lots.)

Page 29 of 84
**Section R313.2 One and Two Family Dwellings; Delete this section and subsection in their
entirety.
(Reason: In 2009, the State Legislature enacted SB 1410, amending section 1301.551
subsection I of the occupation code, prohibiting cities from enacting fire sprinkler mandates
one or two family dwellings only. However, jurisdictions with ordinances that required
sprinklers for one or two family dwellings prior to and enforced before January 1, 2009, may
remain in place.)
***Section R315.2.2 Alterations, repairs and additions; amend to read as follows:
Exception:
1. [existing text remains]
2. Installation, alteration or repairs of all electrically powered mechanical systems or
plumbing appliances.
(Reason: Revised exception for clarity. Code intent is to protect against the products of
combustion.)
**Section R322 Flood Resistant Construction; deleted section.
(Reason: Floodplain hazard ordinances may be administered by other departments within the
city.)
**Section R401.2; amended by adding a new paragraph following the existing paragraph
to read as follows.
Section R401.2. Requirements. {existing text unchanged} …
Every foundation and/or footing, or any size addition to an existing post-tension foundation,
regulated by this code shall be designed and sealed by a Texas-registered engineer.
(Amendment to 2015 IRC carried forward to 2018 IRC.)

**Figure R602.6.1; delete the figure and insert the following figure:
(Amendment to 2015 IRC carried forward to 2018 IRC also provides additional assurance of
maintaining the integrity of the framing by spreading the nailing pattern.)
***Add section R703.8.4.1.2 Veneer Ties for Wall Studs; to read as follows:
R703.8.4.1.2 Veneer Ties for Wall Studs. In stud framed exterior walls, all ties may be
anchored to studs as follows:
1. When studs are 16 in (407 mm) o.c., stud ties shall be spaced no further apart than 24
in (737 mm) vertically starting approximately 12 in (381 mm) from the foundation; or
2. When studs are 24 in (610 mm) o.c., stud ties shall be spaced no further apart than 16
in (483 mm) vertically starting approximately 8 in (254 mm) from the foundation.
(This amendment had been a carry over amendment for years to provide clear instruction for
placement of brick ties. It is now retained with changes to reflect its correct placement and use
for clarity when attachment to framing lumber (studs). It should remain for those purposes. It
is in addition to the new new Table in 2018 which provides for brick ties directly to sheathing.)
**Section R902.1; amend and add exception #5 to read as follows:
R902.1 Roofing covering materials. Roofs shall be covered with materials as set forth in

**Section G2417.4; change to read as follows:
G2417.4 (406.4) Test pressure measurement. Test pressure shall be measured with a
monometer or with a pressure-measuring device designed and calibrated to read, record, or
indicate a pressure loss caused by leakage during the pressure test period. The source of
pressure shall be isolated before the pressure tests are made. Mechanical gauges used to
measure test pressures shall have a range such that the highest end of the scale is not greater
than five times the test pressure.
(Reason: To require the use of more accurate diaphragm gauges. Spring gauges do not
provide accurate measurement below approximately 17 psig.)
**Section G2417.4.1; change to read as follows:
G2417.4.1 (406.4.1) Test pressure. The test pressure to be used shall be no less than 3 psig
(20 kPa gauge), or at the discretion of the Code Official, the piping and valves may be tested at
a pressure of at least six (6) inches (152 mm) of mercury, measured with a manometer or slope
gauge, irrespective of design pressure. Where the test pressure exceeds 125 psig (862 kPa
gauge), the test pressure shall not exceed a value that produces a hoop stress in the piping greater
than 50 percent of the specified minimum yield strength of the pipe. For tests requiring a
pressure of 3 psig, diaphragm gauges shall utilize a dial with a minimum diameter of three and
one half inches (3 ½”), a set hand, 1/10 pound incrementation and pressure range not to exceed
6 psi for tests requiring a pressure of 3 psig. For tests requiring a pressure of 10 psig, diaphragm
gauges shall utilize a dial with a minimum diameter of three and one-half inches (3 ½”), a set
hand, a minimum of 2/10 pound incrementation and a pressure range not to exceed 20 psi. For
welded piping, and for piping carrying gas at pressures in excess of fourteen (14) inches water
column pressure (3.48 kPa) (1/2 psi) and less than 200 inches of water column pressure (52.2
kPa) (7.5 psi), the test pressure shall not be less than ten (10) pounds per square inch (69.6 kPa).
For piping carrying gas at a pressure that exceeds 200 inches of water column (52.2 kPa) (7.5
psi), the test pressure shall be not less than one and one-half times the proposed maximum
working pressure.
Diaphragm gauges used for testing must display a current calibration and be in good working
condition. The appropriate test must be applied to the diaphragm gauge used for testing
(Reason: To provide for lesser pressures to coordinate with the use of more accurate diaphragm
gauges.)

the test pressure shall be not less than one and one-half times the proposed maximum working
pressure.
Diaphragm gauges used for testing must display a current calibration and be in good working
condition. The appropriate test must be applied to the diaphragm gauge used for testing.
(Reason: To provide for lesser pressures to coordinate with the use of more accurate
diaphragm gauges.)
**Section 409.1; add Section 409.1.4 to read as follows:
409.1.4 Valves in CSST installations. Shutoff valves installed with corrugated stainless steel
(CSST) piping systems shall be supported with an approved termination fitting, or equivalent
support, suitable for the size of the valves, of adequate strength and quality, and located at
intervals so as to prevent or damp out excessive vibration but in no case greater than 12-inches
from the center of the valve. Supports shall be installed so as not to interfere with the free
expansion and contraction of the system's piping, fittings, and valves between anchors. All
valves and supports shall be designed and installed so they will not be disengaged by movement
of the supporting piping.
(Reason: To provide proper security to CSST valves. These standards were established in this
region in 1999 when CSST was an emerging technology.)
**Section 410.1; add a second paragraph and exception to read as follows:
Access to regulators shall comply with the requirements for access to appliances as specified
in Section 306.
Exception: A passageway or level service space is not required when the regulator is
capable of being serviced and removed through the required attic opening.
(Reason: To require adequate access to regulators.)
**Section 621.2; add exception as follows:
621.2 Prohibited use. One or more unvented room heaters shall not be used as the sole source
of comfort heating in a dwelling unit.
Ordinance 888
Page 55 of 84
Exception: Existing approved unvented heaters may continue to be used in dwelling units,
in accordance with the code provisions in effect when installed, when approved by the Code
Official unless an unsafe condition is determined to exist as described in Section 108.7.
(Reason: Gives code official discretion.)
Amendments to the 2018 International Energy Conservation
Code.
The following sections, paragraphs, and sentences of the 2018 International Energy
Conservation Code (IECC) are hereby amended as follows: Standard type is text from the
IECC. Underlined type is text inserted. Lined through type is deleted text from IECC. A double
(**) asterisk at the beginning of a section identifies an amendment carried over from the 2015
edition of the code and a triple (***) asterisk identifies a new or revised amendment with the
2018 code. Section numbers in parenthesis represent the corresponding numbers of the energy
provisions of the 2018 International Residential Code for parallel amendments.
2018 IECC (Energy Provisions of the 2018 IRC)
**Section C102/R102 General; add Section C102.1.2 and R102.1.2 (N1101.4.1) to read as
follows:
C102.1.2 Alternative compliance. A building certified by a national, state, or local accredited
energy efficiency program and determined by the Energy Systems Laboratory to be in
compliance with the energy efficiency requirements of this section may, at the option of the
Code Official, be considered in compliance. The United States Environmental Protection
Agency's Energy Star Program certification of energy code equivalency shall be considered in
compliance.
R102.1.2 (N1101.4.1) Alternative compliance. A building certified by a national, state, or
local accredited energy efficiency program and determined by the Energy Systems Laboratory
to be in compliance with the energy efficiency requirements of this section may, at the option
of the Code Official, be considered in compliance. The United States Environmental Protection
Agency's Energy Star Program certification of energy code equivalency shall be considered in
compliance. Regardless of the program or the path to compliance, each 1- and 2-family
dwelling shall be tested for air and duct leakage as prescribed in Section R402.4.1.2
(N1102.4.1.2) and R403.3.3 (N1103.3.3) respectively.
(Reason: This amendment is added to allow alternative compliance in accordance with Texas
HB 1365, 78th Legislature. Codified in Chapter 388 Texas Building Energy Performance
Standards: §388.003(i).
The last sentence to Section R102.1.2 (N1101.4.1) was added to insure that every house is tested
in accordance with the mandatory provisions of the code.)
Ordinance 888
Page 56 of 84
Section R202 (N1101.6) Definitions; add the following definition:
**PROJECTION FACTOR. The ratio of the horizontal depth of the overhang, eave or
permanently attached shading device, divided by the distance measured vertically from the
bottom of the fenestration glazing to the underside of the overhang, eave or permanently
attached shading device.
(Reason: The amendment to Section 402.3.2 (N1102.3.2) Glazed fenestration SHGC was
proposed by the TAB. ESL determined the proposal to be not less restrictive than the 2015
IECC. This added definition is necessary as part of that amendment. The amendment will
provide additional options for SHGC selection.)
Section R202 (N1101.6) Definitions; add the following definition:
**DYNAMIC GLAZING. Any fenestration product that has the fully reversible ability to
change it performance properties, including U-factor, solar heat gain coefficient (SHGC), or
visible transmittance (VT).
(Reason: This term is referenced in Section R402.3.2. This definition of DYMANIC GLAZING
is also found in the Commercial provisions of the code.)
***Table 402.1.2 (N1102.1.2) INSULATION AND FENESTRATION REQUIREMENTS

(Reason: Carries forward the value in the 2015 IECC/IRC.)
**Section R402.3.2 (N1102.3.2) Glazed fenestration SHGC; amend by adding a paragraph
and table following the exception to read as follows:
Where vertical fenestration is shaded by an overhang, eave, or permanently attached shading
device, the SHGC required in Table R402.1.2 shall be reduced by using the multipliers in Table
R402.3.2 SHGC Multipliers for Permanent Projections.

a North oriented means within 45 degrees of true north.
(Reason: The amendment to Section 402.3.2 Glazed fenestration SHGC was proposed by the
TAB and ESL determined the proposal to be not less restrictive than the 2015 IECC. This added
definition is necessary as part of that amendment. The amendment will provide additional
options for SHGC selection.)
**R402.4.1.2 (N1102.4.1.2) Testing; add a last paragraph to read as follows:
Mandatory testing shall only be performed by individuals that are certified to perform air
infiltration testing certified by national or state organizations as approved by the building
official. The certified individuals must be an independent third-party entity, and may not be
employed; or have any financial interest in the company that constructs the structure.
(Reason: The 2018 International Residential Code (IRC) and International Energy
Conservation Code (IECC) includes enhanced emphasis on envelope infiltration and duct
leakage. Significant changes in the residential energy requirements include more frequent
requirement of performance testing for leakage. Residential Duct systems must be tested unless
all ducts and equipment are located within the conditioned space. Envelope testing is required
to demonstrate compliance with maximum allowable leakage rate. This language puts the
regulatory authority on notice that the testing requires specialized credentials and establishes
a conflict of interest baseline.)
***Section R402.4 (N1102.4) Air leakage (Mandatory); add a new section and table to read
as follows:
R402.4.1.3 (N1102.4.1.3) Testing option – ACH tradeoff. As an option to the air leakage rate
set out in Section R402.4.1.2 (N1102.4.1.2), 1- and 2-family homes meeting all of the listed
criteria below and the thermal envelope requirements in Table R402.4.1.3 (N1102.4.1.3) will
be considered compliant when tested and verified as having an air leakage rate to not less than
or equal to four air changes per hour when tested and reported in accordance with the testing
standards and reporting criteria listed in Section R402.4.1.2 (N1102.4.1.2).
Ordinance 888
Page 58 of 84
The compliance equivalency is limited as follows:
1. Limited to a conditioned floor area between 1,000 and 6,000 square feet,
2. Limited to between 2 to 6 bedrooms,
3. Assumes all ductwork and mechanical equipment is located in the unconditioned attic,
4. Assumes typical wood framing in the walls and roof, and
5. Assumes one of the following heating/cooling systems:
a. All electric system with a heat pump for heating, or
b. A system with electric cooling and natural gas heating.
Dwellings using electric resistance strip heating do not qualify for this tradeoff.
TABLE R402.4.1.3 (N1102.4.1.3)a

applicable.
b The first value listed is the R-value of cavity insulation, the second value is the R-value of
the continuous insulation or insulated siding.
(Reason: This provides a viable option to the single-family residential builder. The Energy
Systems Laboratory determined that this tradeoff option to be not less stringent than the
residential provisions of the 2015 IECC and the energy provisions of the 2015 IRC.)
*** Section R402.4 Air leakage (Mandatory); add a new section to read as follows:
R402.4.1.4 Testing options for R2 multifamily dwelling units. As an option to the air leakage
rate set out in Section R402.4.1.2, multifamily dwelling units will be considered compliant
when tested and verified as having an air leakage rate to the air leakage rate set out in either
Section R402.4.1.4.1 or Section R402.4.1.4.2 when tested and reported in accordance with the
testing standards and reporting criteria listed in Section R402.4.1.2
R402.4.1.4.1 Total air leakage rate for interior multifamily dwelling units. Interior
multifamily dwelling units with a measured, “unguarded” total air leakage result of 5.3
ACH50 or less shall be considered compliant.
Ordinance 888
Page 59 of 84
R402.4.1.4.2 Total air leakage rate for corner multifamily dwelling units. Corner
multifamily units with a measured, “unguarded” total leakage result of less than 5.0
ACH50 shall be considered compliant.
(Reason: The Mandatory Section R402.4 Air Leakage of the 2015 IECC requires that the
building thermal envelope be tested and verified in accordance with R402.4.1.2. Measuring
air leakage for multifamily buildings or dwelling units using an air leakage to outside test (i.e.
guarded) can be costly and time prohibitive. This is because in order to isolate leakage only
through the building thermal envelope, all leakage to adjacent units through adiabatic surfaces
must be pressure neutralized. The methodology below therefore allows for the use of total air
leakage testing for multifamily dwelling units that includes air leakage to the exterior and to
adjacent units (i.e. unguarded) to show compliance with R402.4.1.2. This increases the
flexibility of the code without affecting stringency. This methodology has been approved for
use by ESL, and the methodology applies only to jurisdictions in the NCTCOG area.)
*** Section R402.4 Air leakage (Mandatory); add a new section to read as follows:
R402.4.1.5 Sampling options for R2 multifamily dwelling units. For buildings having three
or more dwelling units, a minimum of 15% of the dwelling units in each building must be
tested as required by Section R402.4.1.2. Prior to beginning sampling for testing, “Initial
Testing” is required for each multifamily property. “Initial Testing” shall consist of the 3rd
party testing contractor performing the required tests on at least three consecutive dwelling
units. Test results from the “Initial Testing” must satisfy minimum code requirements before
sampling is permitted. Dwelling units selected for the “Initial Testing” must be within the
same building. Dwelling units selected for “Initial Testing” shall not be included in a “sample
group” or counted toward the minimum 15% of dwelling units tested. The building official
shall randomly select the three dwelling units for “Initial Testing.” The building official may
delegate the random selection to the designated 3rd party testing contractor.
R402.4.1.5.1 Sample group Identification and Sampling. The builder shall identify
a "sample group" which may be a building, floor, fire area or portion thereof. All of
the dwelling units within the “sample group” must be at the same stage of construction
and must be ready for testing. The building official shall randomly select at least 15%
of dwelling units from each “sample group” for testing. The building official may
delegate the random selection to the designated 3rd party testing contractor.
If each tested dwelling unit within a “sample group” meets the minimum code
requirements, then all dwelling units in the “sample group” are considered to meet the
minimum code requirements.
Before a building may be deemed compliant with the testing as required, each “sample
group” must be deemed compliant with the minimum code requirements. The sum
total of all of the tested dwelling units across all “sample groups” shall not be less than
a minimum of 15% of the dwelling units in a building.
R402.4.1.5.2 Failure to Meet Code Requirement(s). If any dwelling units within the
identified “sample group” fail to meet a code requirement as determined by testing,
the builder will be directed to correct the cause(s) of failure, and 30% of the remaining
Ordinance 888
Page 60 of 84
dwelling units in the “sample group” will be randomly selected for testing by the
building official, or third-party testing contractor, regarding the specific cause(s) of
failure.
If any failures occur in the additional dwelling units, all remaining dwelling units
in the sample group must be individually tested for code compliance.
A multifamily property with three failures within a 90-day period is no longer
eligible to use the sampling protocol in that community or project until successfully
repeating "Initial Testing." Sampling may be reinstated after at least three
consecutive dwelling units are individually verified to meet all code requirements.
A Certificate of Occupancy may not may be issued for any building until testing has
been performed and deemed to satisfy the minimum code requirements on the
dwelling unit(s) identified for testing.
(Reason: For many multifamily (R2 classifications) projects, it is very costly and time
consuming to test each dwelling unit for projects where there may be dozens of dwelling units
in each building. Considering that the same tradesman generally constructs a building, it is
reasonable to deem that construction practices are consistent and that if a reasonable
sampling of units tested pass then all units would pass. These amendments are very similar to
other ordinances/policies from Austin and San Antonio.)
** R403.3.3 (N1103.3.3) Duct Testing (Mandatory); add a last paragraph to read as follows:
Mandatory testing shall only be performed by individuals that are certified to perform duct
testing leakage testing certified by national or state organizations as approved by the building
official. The certified individuals must be an independent third-party entity, and may not be
employed; or have any financial interest in the company that constructs the structure.
(Reason: The 2015 International Residential Code (IRC) and International Energy
Conservation Code (IECC) includes enhanced emphasis on envelope infiltration and duct
leakage. Significant changes in the residential energy requirements include more frequent
requirement of performance testing for leakage. Residential Duct systems must be tested unless
all ducts and equipment are located within the conditioned space. Envelope testing is required

or more dwelling units, a minimum of 15% of the dwelling units in each building must be
tested as required by Section R403.3.3. Prior to beginning sampling for testing, “Initial
Testing” is required for each multifamily property. “Initial Testing” shall consist of the 3rd

units. Test results from the “Initial Testing” must satisfy minimum code requirements before
sampling is permitted. Dwelling units selected for the “Initial Testing” must be within the
same building. Dwelling units selected for “Initial Testing” shall not be included in a “sample
group” or counted toward the minimum 15% of dwelling units tested. The building official
shall randomly select the three dwelling units for “Initial Testing.” The building official may
delegate the random selection to the designated 3rd party testing contractor.
R403.3.4.1.1 Sample group Identification and Sampling. The builder shall identify
a "sample group" which may be a building, floor, fire area or portion thereof. All of
the dwelling units within the “sample group” must be at the same stage of construction

**Section C402.2/R402.2 (N1102.2) Specific insulation requirements (Prescriptive); add
Section C402.2.8 and R402.2.14 (N1102.2.14) to read as follows:
Section C402.2.8/R402.2.14 (N1102.2.14) Insulation installed in walls. Insulation installed
in walls shall be totally enclosed on all sides consisting of framing lumber, gypsum, sheathing,
wood structural panel sheathing or other equivalent material approved by the building official.
(Reason: This will increase the performance of the insulation.)
***Section C403.7.4 Energy recovery ventilation systems (Mandatory); add exception #12 to
read as follows:
12. Individual ventilation systems that serve an individual dwelling unit or sleeping unit.
(Reason: This will clarify the intent of the section without requiring the user or the code official
to analyze the numbers in the table. So a ventilation system that serves only an individual
dwelling unit or sleeping unit does not require an energy recovery system.)
***Section C403.11.1 Duct and Plenum Insulation and Sealing (Mandatory); is amended by
adding a second paragraph to read as follows:
Environmental ducts and plenums installed in vertical chases, both supply and exhaust, where
the ducts or plenums will not be accessible after construction completion, shall be leak tested
in accordance with the SMACNA HVAC Air Leakage Test Manual to the installed ductwork
class and pressure requirements.
Documentation shall be furnished demonstrating that representative sections totaling not less
than 25 percent of the duct area have been tested and that all tested sections comply with the
requirements of this section.
(Reason: Ductwork installed in chases is not accessible after construction completion.
Leakage in these ducts will increase the energy use of the buildings and systems for the life of
the building and reduce the system performance. Since the leakage in the chase enclosed
ductwork would be difficult if not impossible to locate and correct, testing at the time of
installation would assure that the ducts are properly installed and efficient.)
***Section R404.1 (N1104.1); revised in its entirety to read as follows:
Section R404.1 (N1104.1) Lighting equipment (Mandatory). Not less than 75 percent of the
lamps in permanently installed lighting fixtures or not less than 75 percent of the permanently
installed lighting fixtures shall contain only high-efficacy lamps.
(Reason: This retains the 2015 language will allows for more flexibility.)
Ordinance 888
Page 63 of 84
**Section 405.2 (N1105.2); add the exception to read as follows:
Section 405.2 (N1105.2) Mandatory requirements. Compliance with the section requires that
the mandatory provisions identified in Section 401.2 be met. Supply and return ducts not
completely inside the building thermal envelope shall be insulated to an R-value of not less than
R-6.
Exceptions:
1. For one and two family dwellings the maximum envelope leakage of 4 ACH50 is
permitted provided the envelope leakage in the Standard Reference Design is 3
ACH50 and all other requirements of Section R405 are met, including all other
mandatory measures. The annual energy cost or source energy usage of the Proposed
Design must be equal to or less than that of the Standard Reference Design.
2. For multifamily or townhomes and buildings classified as Group R2 and Group R4
of three stories or less the maximum envelope leakage of less than 5 ACH50 is
permitted provided the envelope leakage in the Standard Reference Design is 3
ACH50 and all other requirements of Section R405 are met, including all other
mandatory measures. The annual energy cost or source energy usage of the Proposed
Design must be equal to or less than that of the Standard Reference Design.
(Reason: This ACH tradeoff is approved by ESL and will require additional energy efficiencies
to be implemented. This tradeoff is incorporated in ESL’s IC3 Code Compliance Calculator as
the 2015 NCTCOG path in the code drop down menu. Builders using IC3 will receive a code
compliant notification if their designs meet the requirements of this tradeoff and all other
energy code requirements.
Other compliance software products have not incorporated this tradeoff into their compliance
reports. Building Officials receiving Section R405 submittals from software other than IC3 may
approve a R405 compliance report that designates the building as not in compliance due to
noncompliance with the 3 ACH50 envelope leakage mandatory measure, provided the report
also states that the envelope leakage is no greater than 4 ACH50 for single family homes.
REScheck™ does not have the flexibility to accommodate this tradeoff.)
**Section R405.6.2 (N1105.6.2); add the following sentence to the end of paragraph:
Acceptable performance software simulation tools may include, but are not limited to, REM
RateTM; Energy Gauge®; ICF International Beacon Residential; Ekotrope, HERS Module;
Right-Energy HERS and IC3. Other performance software programs as listed by RESNET®
and having the ability to provide a report as outlined in R405.4.2 may also be deemed
acceptable performance simulation programs and may be considered by the building official.
(Reason: These performance software tools are listed by RESNET at the time of
recommendation.)

***Section C408.3.1 Functional Testing; amend to read as follows:
C408.3.1 Functional Testing. Prior to passing final inspection, the registered design
professional or approved agency shall provide evidence that the lighting control systems have
been tested to ensure that control hardware and software are calibrated, adjusted, programmed,
and in proper working condition in accordance with the construction documents and
manufacturer’s instructions. Functional testing shall be in accordance with Sections C408.3.1.1
through C408.3.1.3 for the applicable control type.
(Reason: The addition of ‘or approved agency’ will make the lighting systems requirements
match the mechanical system requirements in C 408.2.1. This will facilitate and add flexibility
to the enforcement of the commissioning requirements.)

(Reason: To prevent potential abuses in new construction and shell buildings.)
**Section 305.1; adds an exception to read as follows:
Exception: Components of projects regulated by and registered with Architectural Barriers
Division of Texas Department of Licensing and Regulation shall be deemed to be
incompliance with the requirements of this chapter.
(Reason: To coordinate with the IEBC and State Law.)
**Section 305.4.2; add Number 7 to the list of requirements as follows:
7. At least one accessible family or assisted use toilet room shall be provided in accordance
with Chapter 11 of the International Building Code.
Ordinance 888
Page 73 of 84
(Reason: Accessible toilet rooms should be available for disabled occupants.)
***Section 401.3 Flood Hazard Areas; delete this section:
(Reason: Flood hazard ordinances may be administered by other departments within the city.)
***Section 405.2.5 Flood Hazard Areas; delete this section:
(Reason: Flood hazard ordinances may be administered by other departments within the city.)
**Section 406.1; add a code reference to read as follows:
406.1 Material. Existing electrical wiring and equipment undergoing repair shall be allowed
to be repaired or replaced with like material, in accordance with the requirements of NFPA
70.
(Reason: To ensure compliance with the NEC relative to any electrical repairs/replacement.)
***Section 502.3 Flood Hazard Areas; delete this section:
(Reason: Flood hazard ordinances may be administered by other departments within the city)
**Section 504.1.2; change to read as follows:
504.1.2 Existing fire escapes. Existing fire escapes shall continue to be accepted as a
component in the means of egress in existing buildings only. Existing fire escapes shall be
permitted to be repaired or replaced.
(Reason: To add clarity and help reduce confusion associated with the amendment preventing
new fire escapes.)
**Section 504.1.3; delete entire section:
504.1.3 New fire escapes. New fire escapes for existing buildings shall be permitted only
where exterior stairways cannot be utilized due to lot lines limiting stairway size or due to the
sidewalks, alleys or roads at grade level. New fire escapes shall not incorporate ladders or
access by windows.
(Reason: To generally require a higher level of egress protection.)
***Section 507.3 Flood Hazard Areas; delete this section:
(Reason: Flood hazard ordinances may be administered by other departments within the city.)
***Section 701.3 Flood Hazard Areas; delete this section:
Ordinance 888

(Reason: Flood hazard ordinances may be administered by other departments within the city.)
**Section 702.6; add a code reference to read as follows:
702.6 Materials and methods. All new work shall comply with the materials and methods
requirements in the International Building Code, International Energy Conservation Code,
International Mechanical Code, National Electrical Code, and International Plumbing Code,
as applicable, that specify material standards, detail of installation and connection, joints,
penetrations, and continuity of any element, component, or system in the building.
(Reason: To provide a more complete list of potentially adopted codes.)
***Section 802.5.1; change to read as follows:
802.5.1 Minimum requirement. Every portion of a floor, such as a balcony or a loading
dock, open-sided walking surfaces, including mezzanines, equipment platforms, aisles, stairs,
ramps and landings that is more than 30 inches (762 mm) above the floor or grade below and
is not provided with guards, or those in which the existing guards are judged to be in danger
of collapsing, shall be provided with guards.
(Reason: To be consistent with Building Code requirements for guards and unsafe
conditions.)
**Section 803.1; add sentence to read as follows:
For the purpose of fire sprinkler protection and fire alarm requirements included in this
section, the work area shall be extended to include at least the entire tenant space or spaces
bounded by walls capable of resisting the passage of smoke containing the subject work area,
and if the work area includes a corridor, hallway, or other exit access, then such corridor,
hallway, or other exit access shall be protected in its entirety on that particular floor level.
(Reason: The intent is to avoid work area protection that would result in partial sprinkler or
fire alarm protection. Partial sprinkler protection not delineated by walls would be a clear
violation of NFPA 13 and would not allow the sprinkler to perform or function as intended.
Also, partial fire alarm coverage is a clear violation of the Fire Code, NFPA 72, and ADA.)
**Section 803.2.4; change exception to read as follows:
Exception: Supervision is not required where the Fire Code does not require such for new
construction
for the following:

5. Automatic sprinkler systems installed in accordance with NFPA 13R where a
common supply main is used to supply both domestic and automatic sprinkler
systems and a separate shutoff valve for the automatic sprinkler system is not
provided.
(Reason: The published exceptions are over-reaching and will result in inconsistencies among
supervised protection systems and cause confusion for first responders as well.)
**Section 803.3; change section to read as follows:
803.3 Standpipes. Refer to Section 1103.6 of the Fire Code for retroactive standpipe
requirements.
{Delete rest of Section 804.3.}
(Reason: The Fire Code already requires standpipes in these buildings (greater than 50 ft.)
retroactively in Section 1103.6. This new section would negate/lessen those retroactive
provisions already contained in the Fire Code.)
**Section 805.2; remove Exception #1
Exception 1. W here the work area and the means of egress serving it complies with
NFPA101.
(Reason: NFPA 101 is not a commonly adopted code in the region and enforcement could be
problematic.)
**Section 805.3.1.2; change to read as follows:
805.3.1.2 Fire Escapes required. For other than Group I-2, where more than one exit is
required an existing or newly constructed fire escape complying with section 805.3.1.2.1 shall
be accepted as providing one of the required means of egress.
(Reason: Higher level of safety by not allowing new fire escapes.)
**Section 805.3.1.2.1; change to read as follows:
805.3.1.2.1 Fire Escape access and details - …
1. [Remain unchanged]

and defined term in IBC.)
Ordinance 888
Page 76 of 84
***Section 805.5.2 Transoms; add language to read as follows:
805.5.2 Transoms. In all buildings of Group B, E, [Remainder unchanged]
(Reason: Transom windows were historically a common practice in school buildings and
each jurisdiction should evaluate the impact on their stakeholders and their community with
regards to section.)
**Section 904.1; add sentence to read as follows:
For the purpose of fire sprinkler protection and fire alarm requirements included in this
section, the work area shall be extended to include at least the entire tenant space or spaces
bounded by walls containing the subject work area, and if the work area includes a corridor,
hallway, or other exit access, then such corridor, hallway, or other exit access shall be
protected in its entirety on that particular floor level.
(Reason: The intent is to avoid work area protection that would result in partial sprinkler or
fire alarm protection. Partial sprinkler protection not delineated by walls would be a clear
violation of NFPA 13 and the Fire Code and would not allow the sprinkler system to perform
or function as intended. Also, partial fire alarm coverage is a clear violation of the Fire
Code, NFPA 72, and ADA.)
**Section 904.1.1; change sentence to read as follows:
904.1.1 High-rise buildings. An automatic sprinkler system shall be provided in work areas
of where the high-rise buildings. has a sufficient municipal water supply for the design and
installation of an automatic sprinkler system at the site.
(Reason: Level 3 alterations are affecting more than 50% of the existing high-rise building,
and as such, sprinkler protection is more than justifiable, even when fire pumps, etc., are
necessary. It is noted that the work area method is one of three different methods available to
the designer/owner in the IEBC.)
***Section 1103.3 Flood Hazard Areas; delete this section:
(Reason: Flood hazard ordinances may be administered by other departments within the city.)
***Section 1201.4 Flood Hazard Areas; delete this section:
(Reason: Flood hazard ordinances may be administered by other departments within the city.)
***Section 1301.3.2; change to read as follows:
1301.3.2 Compliance with other codes. Buildings that are evaluated in accordance with this
section
Ordinance 888
Page 77 of 84
shall comply with the International Fire Code. and International Property Maintenance Code.
(Reason: NCTCOG does not currently review the IPMC for recommended amendments at this
time.)
***Section 1301.3.3 Compliance with Flood Hazard Provisions; delete this section:
(Reason: Flood hazard ordinances may be administered by other departments within the city.)
***Section 1402.6 Flood Hazard Areas; delete this section:

Amendments to the 2017 National Electrical Code.
The following articles, paragraphs, and sentences of the 2017 National Electrical Code (NEC)
are hereby amended as follows: Standard type is text from the NEC. Underlined type is text
inserted. Lined through type is deleted text from NEC. A double asterisk (**) at the beginning
of an article identifies an amendment carried over from the 2014 edition of the code and a triple
asterisk (***) identifies a new or revised amendment with the 2017 code.
**Article 100; add the following to definitions:
Engineering Supervision. Supervision by a Qualified State of Texas Licensed Professional
Engineer engaged primarily in the design or maintenance of electrical installations.
(REASON FOR CHANGE: To better define the qualifications for engineering supervision.
This term is used twenty four times in the 2017 National Electrical Code.)
***Article 100; remove the amendment to the following definition:
Intersystem Bonding Termination. A device that provides a means for connecting intersystem
bonding conductors for communication systems and other systems such as metallic gas piping
systems to the grounding electrode system. Bonding conductors for other systems shall not be
larger than 6 AWG.
(REASON FOR CHANGE: Remove the above amendment. Updates to the 2017 National
Electrical Code Article 250.94(A) only accommodate connecting communication systems to
an intersystem bonding termination device, but Article 250.94(B) provides an alternative or
other means. To allow for a termination point for other bonding conductors in addition to
communication systems that are required by the various model codes. 6 AWG was chosen to
coincide with the minimum size of bonding conductor required to the intersystem bonding
jumper.)
Ordinance 888
Page 78 of 84
**Article 110.2; change the following to read as follows:
110.2 Approval. The conductors and equipment required or permitted by this Code shall be
acceptable only if approved. Approval of equipment may be evident by listing and labeling of
equipment by a Nationally Recognized Testing Lab (NRTL) with a certification mark of that
laboratory or a qualified third party inspection agency approved by the AHJ.
Exception: Unlisted equipment that is relocated to another location within a jurisdiction or is
field modified is subject to the approval by the AHJ. This approval may be by a field
evaluation by a NRTL or qualified third party inspection agency approved by the AHJ.
Manufacturer’s self-certification of any equipment shall not be used as a basis for approval by
the AHJ.
Informational Note No. 1: See 90.7, Examination of Equipment for Safety, and 110.3,
Examination, Identification, Installation, and Use of Equipment. See definitions of Approved,
Identified, Labeled, and Listed.
Informational Note No. 2: Manufacturer’s self-certification of equipment may not necessarily
comply with U.S. product safety standards as certified by an NRTL.
Informational Note No. 3: National Fire Protection Association (NFPA) 790 and 791 provide
an example of an approved method for qualifying a third party inspection agency.
(REASON FOR CHANGE: To add clarity and provide more positive options for enforcement
and approval of unlisted equipment.)
***Article 210.52(G) (1) Garages: remove the amendment that deleted the following:
(1) Garages. In each attached garage and in each detached garage with electric power. The
branch circuit supplying this receptacle(s) shall not supply outlets outside of the garage. At
least one receptacle outlet shall be installed for each car space.
(REASON FOR CHANGE: Installations in compliance with this Code are not necessarily
efficient, convenient, or adequate for good service or future expansion of electrical use.)
(REASON FOR CHANGE: Updates to this section in the 2017 National Electrical Code
provided relief by removing “shall not supply outlets outside of the garage.”)
***Article 230.71(A); remove the amendment that added the following exception:
Exception: Multi-occupant buildings. Individual service disconnecting means is limited to six
for each occupant. The number of individual disconnects at one location may exceed six.
(REASON FOR CHANGE: This is currently the accepted installation practice of the region.
No noteworthy complaints have surfaced. It is more reasonable than the current NEC
Ordinance 888
Page 79 of 84
requirements. It allows more than six disconnects grouped at one location. This also allows
designers more flexibility in the placement of electrical meters and main service disconnects.)
(REASON FOR CHANGE: This is below the minimum standard of the 2017 National
Electrical Code adopted by the State of Texas.)
***Article 300.11; remove the amendment that added the following exception:
Exception: Ceiling grid support wires may be used for structural supports when the associated
wiring is located in that area, not more than two raceways or cables supported per wire, with a
maximum nominal metric designation 16 (trade size 1/2”).
(REASON FOR CHANGE: To provide limited support of raceways and cables by ceiling grid
support wire.)
(REASON FOR CHANGE: This is below the minimum standard of the 2017 National
Electrical Code adopted by the State of Texas.)
***Article 310.15(B) (7); remove the amendment that changed the following to read as
follows:
(7) This Article shall not be used in conjunction with 220.82.
(REASON FOR CHANGE: 310.15(B) (7) has been revised and the table has been deleted.)
(REASON FOR CHANGE: Upon review of the 2014 and 2017 code-making panel 6 and in
conjunction with the wire manufacturing industry, based on the diversification of loads in
modern construction, this amendment becomes irrelevant.)
**Article 500.8 (A) (3); change to read as follows:
500.8 Equipment.
Articles 500 through 504 require equipment construction and installation that ensure safe
performance under conditions of proper use and maintenance.
Informational Note No. 1: It is important that inspection authorities and users exercise more
than ordinary care with regard to installation and maintenance.
Informational Note No. 2: Since there is no consistent relationship between explosion
properties and ignition temperature, the two are independent requirements.
Informational Note No. 3: Low ambient conditions require special consideration. Explosion
proof or dust-ignition proof equipment may not be suitable for use at temperatures lower than
-25°C
(-13°F) unless they are identified for low-temperature service. However, at low ambient
temperatures, flammable concentrations of vapors may not exist in a location classified as
Class I, Division 1 at normal ambient temperature.
Ordinance 888
Page 80 of 84
(A) Suitability. Suitability of identified equipment shall be determined by one of the
following:
(1) Equipment listing or labeling;
(2) Evidence of equipment evaluation from a qualified testing laboratory or inspection
agency concerned with product evaluation; or,
(3) Evidence acceptable to the authority having jurisdiction such as a manufacturer's self-
evaluation or an owner's engineering judgment. an engineering judgment signed and
sealed by a qualified Registered licensed Professional Engineer in the State of Texas.
Informational Note: Additional documentation for equipment may include certificates
demonstrating compliance with applicable equipment standards, indicating special conditions
of use, and other pertinent information.
(REASON FOR CHANGE: Carry over from previous amendment with change to better define
the qualifications for an engineering judgment.)
**Article 505.7 (A) changed to read as follows:
505.7 Special Precaution.
Article 505 requires equipment construction and installation that ensures safe performance
under conditions of proper use and maintenance.
Informational Note No. 1: It is important that inspection authorities and users exercise more
than ordinary care with regard to the installation and maintenance of electrical equipment in
hazardous (classified) locations.
Informational Note No. 2: Low ambient conditions require special consideration. Electrical
equipment depending on the protection techniques described by 505.8(A) may not be suitable
for use at temperatures lower than -20°C (-4°F) unless they are identified for use at lower
temperatures. However, at low ambient temperatures, flammable concentrations of vapors
may not exist in a location classified Class I, Zones 0, 1, or 2 at normal ambient temperature.
(A) Implementation of Zone Classification System. Classification of areas, engineering
and design, selection of equipment and wiring methods, installation, and inspection
shall be performed by a qualified persons Registered licensed Professional Engineer in
the State of Texas.
(REASON FOR CHANGE: Carry over from previous amendment with change to better define
the qualifications for an engineering judgment.)
***Article 517.30 Essential Electrical Systems for Hospitals; remove the amendment
that created a new (H) and added the following language:
Ordinance 888
Page 81 of 84
(G) Coordination. Overcurrent protective devices serving the equipment branch of the
essential electrical system shall be coordinated for the period of time that a fault’s duration
extends beyond 0.1 second.
Exception No. 1: Between transformer primary and secondary overcurrent protective devices,
where only one overcurrent protective device or set of overcurrent protective
devices exists on the transformer secondary.
Exception No. 2: Between overcurrent protective devices of the same size (ampere rating) in
series.
Informational Note: The terms coordination and coordinated as used in this section do not
cover the full range of overcurrent conditions.
(H) Selective Coordination. Overcurrent protective devices serving the life safety, and
critical branches of the essential electrical system shall be selectively coordinated with all
supply-side overcurrent protective devices.
Exception No. 1: Between transformer primary and secondary overcurrent protective devices,
where only one overcurrent protective device or set of overcurrent protective
devices exists on the transformer secondary.
Exception No. 2: Between overcurrent protective devices of the same size (ampere rating) in
series.
Informational Note: The terms coordination and coordinated as used in this section do not
cover the full range of overcurrent conditions.
(REASON FOR CHANGE: Changes made by deleting the definition of emergency systems in
Article 517 Health Care Facilities and removing emergency systems as “Essential Electrical
Systems for Hospitals in 517.30(B) (2), plus the new addition of section 517.30(G) for
“Coordination” instead of using selective coordination, has diminished the reliability of the
“Life Safety and Critical Branches of the Essential Electrical System” to deliver power to
vital loads. By providing only “coordination,” the instantaneous portion of the time-current
curve has been eliminated from the overcurrent device settings.)
(REASON FOR CHANGE: Due to no action by the 2017 code-making panel 15 and NFPA
99, this amendment is not applicable.)
***Article 600.6(A) (1) At Point of Entry to a Sign; Exception 1 changed to read as
follows:
Exception No.1: A disconnect shall not be required for branch circuits(s) or feeder
conductor(s) passing through the sign where enclosed in a Chapter 3 listed raceway or metal-
jacketed cable identified for the location. The conductor(s) shall not serve the sign body or
sign enclosure where passing through.
Ordinance 888
Page 82 of 84
***Article 600.6(A) (1) At Point of Entry to a Sign; create a new Exception No. 2 to add
the following language:
Exception No. 2. A disconnect shall not be required at the point of entry to a sign body, sign
enclosure, or pole for branch circuit conductor(s). The conductors shall be enclosed in a
Chapter 3 listed raceway or metal-jacketed cable identified for the location. The conductor(s)
shall be routed to a device box which contains the disconnect. A field-applied permanent
warning label that is visible during servicing shall be applied to the raceway at or near the
point of entry into the sign enclosure or sign body. The warning label shall comply with
110.21(B) and state the following: “Danger. This raceway contains energized conductors.”
The marking shall include the location of the disconnecting means for the energized
conductor(s). The disconnecting means shall be capable of being locked in the open position
in accordance with 110.25.
***Article 600.6(A) (1) At Point of Entry to a Sign; move the original Exception 2 to
create a new Exception No. 3 and add the following language:
Exception No. 3: A disconnect shall not be required at the point of entry to a sign enclosure or
sign body for branch circuit(s) or feeder conductor(s) that supply an internal panelboard(s) in
a sign enclosure or sign body. The conductors shall be enclosed in a Chapter 3 listed raceway
or metal-jacketed cable identified for the location. A field-applied permanent warning label
that is visible during servicing shall be applied to the raceway at or near the point of entry into
the sign enclosure or sign body. The warning label shall comply with 110.21(B) and state the
following: “Danger. This raceway contains energized conductors.” The marking shall include
the location of the disconnecting means for the energized conductor(s). The disconnecting
means shall be capable of being locked in the open position in accordance with 110.25.
(2017 Code) Informational Note: The location of the disconnect is intended to allow service
or maintenance personnel complete and local control of the disconnecting means.
(REASON FOR CHANGE: This is a modification of the nationwide sign manufacturing
practice that was standard before the 2014 Code revision. It is more reasonable but not less
than the current Code requirements. It provides local control of the disconnect by service
personnel as the informational note suggests, while requiring a sign disconnect to be at or
within sight of the sign. This also allows sign designers more flexibility in the placement of
the disconnecting means in relation to the location of the sign.)
***Article 680.25(A) remove the amendment that added the following language and
exception:
680.25 Feeders.
These provisions shall apply to any feeder on the supply side of panelboards supplying branch
circuits for pool equipment covered in Part II of this article and on the load side of the service
equipment or the source of a separately derived system.
Ordinance 888
Page 83 of 84
(A) Wiring Methods.
(1) Feeders. Feeders shall be installed in rigid metal conduit, intermediate metal conduit. The
following wiring methods shall be permitted if not subject to physical damage:
(1) Liquid-tight flexible nonmetallic conduit
(2) Rigid polyvinyl chloride conduit
(3) Reinforced thermosetting resin conduit
(4) Electrical metallic tubing where installed on or in a building
(5) Electrical nonmetallic tubing where installed within a building
(6) Type MC Cable where installed within a building and if not subject to corrosive
environment
(7) Nonmetallic-sheathed cable
(8) Type SE cable
Exception: A feeder within a one-family dwelling or two-family dwelling unit between
remote panelboard and service equipment shall be permitted to run in flexible metal conduit
or an approved cable assembly that includes an insulated equipment grounding conductor
within its outer sheath. The equipment grounding conductor shall comply with 250.24(A) (5).
(REASON FOR CHANGE: Carry over from previous amendments. Text changed to reflect
2014 National Electrical Code. Exception deleted per Errata No.70-14-2)
(REASON FOR CHANGE: Updates to this section in the 2017 National Electrical Code
provided relief by recognizing these wiring methods.)
