WHEREAS, the City of Kennedale is a home rule city acting under its charter
adopted by the electorate pursuant to Article XI, Section 5 of the Texas Constitution and
Chapter 9 of the Local Government Code; and
WHEREAS, the 2001 Texas Legislature in Senate Bill 365 amended Chapter 214

Kennedale may be made when deemed appropriate.
NOW, THEREFORE, BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF
KENNEDALE, TEXAS:
SECTION 1.
The 2000 Edition of the International Residential Code is hereby adopted as the
official residential building code of the City of Kennedale, Texas. This residential code is
fully incorporated by reference as though copied into this ordinance in its entirety. The
material contained in the International Residential Code shall not be included in the formal
municipal codification of ordinances but shall be maintained as a public record in the office
of the City Secretary and will be available for public inspection and copying during regular

North Central Texas 4 February 2001
2000 IRC amendments
**Section N1101.2; amend as follows:
N1101.2.1 Residential Buildings, Type A-1. Compliance shall be demonstrated by-eit#er one of the
following:
1. Meeting the requirements of this chapter for buildings with a glazing area that does not exceed 15
percent of the gross area of exterior walls; ex
2. Meeting the requirements of this chapter for buildings with a glazing area that is greater than 15
percent but not exceeding 20 percent of the gross area of exterior walls and air conditioning
equipment rated 12 SEER or higher;
3. Meeting the requirements of this chapter for buildings with a glazing area that is greater than 20
percent but not exceeding 25 percent of the gross area of exterior walls and air conditioning
equipment rated 14 SEER or higher; or
4. Meeting the requirements of the International Energy Conservation Code for residential buildings,
Type A-1.
(Reason: This amendment would increase the number of builders who could use this "simplified
prescriptive" approach of the IRC. It accommodates particularly the move-up and luxury homes with
large glazing areas. The trade-off with air-conditioning is an option under the IECC systems analysis or
MECcheck approach, and is brought into this format for convenience only. Other IECC trade-offs would
also remain available. The intent is to maintain compatibility with the IECC. The intent would include
adjustment of this provision at such future date that the minimum federal equipment standards are raised
to achieve equivalent increases in energy savings.)
**Add Section N1101.3.4 to read as follows:
N1101.3.4 Exterior basement or slab insulation. When susceptibility to termite damage is classified as
"very heavy" according to Table R301.2(1). designs emplovinQ basement or slab exterior insulation
capable of harboring termites shall not be utilized.
(Reason: Usage of exterior insulation provides access for termites. This amendment does not preclude
the use of insulating coatings that do not provide termite access or shelter.)
"*Section N1102.1 amend as follows:
N1102.1 Thermal performance criteria. The minimum required insulation R-value or maximum required
U-factor for each element in the building thermal envelope (fenestration, roof/ceiling, opaque wall, floor,
slab edge, crawl space wall and basement wall) shall be in accordance with the criteria in Table
. N1102.1.
Residential building, Type A-1, with greater than a-5-25-percent glazing area; residential buildings, Type
A-2, with greater than 25-percent glazing area; and any building in climates with HDD equal to or greater
than 13,000; shall determine compliance using the building envelope requirements of the International
Energy Conservation Code.
(Reason: This amendment corrects an error in the section and is compatible with the previous
amendment increasing allowable glazing area, effectively increasing the number of builders who could
use the "simplified prescriptive" approach of the IRC.)
North Central Texas 5 February 2001
2000 IRC amendments
**Replace Table N1102.1 with:
TABLE N1102.1
SIMPLIFIED PRESCRIPTIVE BUILDING ENVELOPE THERMAL COMPONENT CRITERIA
MINIMUM REQUIRED THERMAL PERFORMANCE (U-FACTOR AND R-VALUE)
MINIMUM INSULATION R-VALUE [(haft • F)/Btu]
MAXIMUM Ceilings Ceiling

U-FACTOR Attic Rafter Walls perimeter space
[Btu/(hr~ftZ~ F)] Space Assembly walls
0.65 R-38 R-22 R-13 R-19 R-0 R-0 R-0
(Reason: This amendment is compatible with the previous amendments increasing the number of
builders who could use the "simplified prescriptive" approach of the IRC and incorporates the Home
Builder Association prescriptive package proposal. The addition of "Ceiling Joist/Roof Rafter Assembly"
requirements protect such assemblies from the damage likely to occur if greater amounts of insulation
were attempted in such assemblies.)
Section N1102.2 amend as follows:
N1102.2 Maximum solar heat gain coefficient for fenestration products. The area-weighted-
average solar heat gain coefficient (SHGC) for glazed fenestration installed in climate zones' °,-~-'~~
~~with less than 3,500 HDD~ shall not exceed 0.40.
(Reason: This amendment corrects a printing error in the IRC and avoids confusion over the intent to
maintain consistency with requirements of the IECC.)
**Add Section M1304.2 to read as follows:
M1304.2 Minimum burial depth. Underground fuel piping systems shall be installed a minimum depth
of 18 inches (458 mm) below grade.
(Reason: To provide increased protection to piping systems.)
**Section M1305.1.3; change to read as follows:
M1305.1.3 Appliances in attics. Attics containing appliances requiring access shall be provided .. .
{bulk of paragraph unchanged} ...sides of the appliance where access is required. The clear access
opening dimensions shall be a minimum of 20 inches by 30 inches (508 mm by 762 mm), or larger where
such dimensions are not large enough to allow removal of the largest appliance. As a minimum, access
to the attic space shall be provided by one of the following:
1. A permanent stair.
2. A pull down stair.
3. An access door from an upper floor level.
Exception: The passageway and level service space are not required where the appliance is
capable of being serviced and removed through the required opening.
(Reason: To provide a safe means of accessibility to appliances in attics.)

accessible by a stairway or permanent ladder fastened to the building.
M1305.1.5.1 Whenever the mezzanine or platform is not adequately lighted or access to a
receptacle outlet is not obtainable from the main level lighting and a receptacle outlet shall be
provided in accordance with Section M1305.1.3.1.
(Reason: To provide safe access to water heaters and to provide lighting and receptacle for maintenance
of equipment.)
**Section M1305.1.3.1; add a sentence to read as follows:
Low voltage wiring of 50 Volts or less shall be installed in a manner to prevent physical damage.
(Reason: To call attention to the need for care while installing lighting wiring in attic.)
**Section M1305.1.4.1; change to read as follows:
M1305.1.4.1 Ground clearance. Appliances supported from the ground shall be level and firmly
supported on a concrete slab or other approved material extending above the adjoining grade a minimum
of 3 inches (76 mm). Appliances suspended from the floor shall have a clearance of not less than 6
inches (152 mm) above the ground.
(Reason: Consistent with current local practice.)
**Section M1305.1.4.3; add a sentence to read as follows:
Low voltage wiring of 50 Volts or less shall be installed in a manner to prevent physical damage.
(Reason: To call attention to the need for care while installing lighting wiring under floors.)
**Section M1307.3.1; delete.
(Reason: This provision does not reflect standard practice in this area.)
**Section M1501.2; change to read as follows:
M1501.2 Exhaust duct size. The minimum diameter of the exhaust duct shall be as recommended by
the manufacturer) ar}d shall be at least the diameter of the appliance outlet and shall be a minimum
nominal size of 4 inches (102 mm) in diameter. The size of duct shall not be reduced along its developed
length nor at the point of termination.
(Reason: To clarify the size requirement.)

When extra bends are installed, the maximum length of the duct shall be reduced 2.5 feet (762 mm) for
each 45-degree (0.79 rad) bend and 5 feet (1524 mm) for each 90-degree (1.6 rad) bend that occur after
the first two bends, measuring in the direction of airflow. The maximum length of the exhaust duct does
not include the transition duct.
{Exception is unchanged}
(Reason: To make more consistent with regional practice. Dryer technology has improved to the point
where they should be capable of handling this.)
""Section M1601.3.4, item #1; change to read as follows:
1. Duct insulation shall conform to the requirements of Table M1601.3.4 and Section N1101.2. Should
there be any conflicts between this section and the energy efficiency provisions, the energy efficiency
provisions shall take precedence.
A vapor retarder in accordance with Table M1601.3.4
r~.Q~-~g%~~~ , or aluminum foil having a minimum thickness of
2 mils (0.051 mm), shall be installed on the exterior of insulation on cooling supply ducts that pass
through nonconditioned spaces conducive to condensation.
Insulations having a permeance of 0.05 perms f2.87 ng/(Pa s m2)1 or less shall not be required to
be covered.

Recommended Amendments to the
1999 National Electrical Code
REGIO\.V..aI~IEND~II~:N~TS*
**Section 230-2(a) add a sixth Special Condition.
230-2. Number of Services. A building or other structure served shall be supplied by only one
service unless permitted in (a) through (d). For the purpose... {text unchanged} ...shall be considered
to be supplying one service.
(a). Special Conditions. Additional services shall be permitted to supply
(1) Fire Pumps
(6) In supplying electrical service to multifamily dwellings, two or more laterals or overhead
service drops shall be permitted to a building when both of the following conditions are met:
a. The building has six or more individual gang meters and all meters are grouped at the same
location.
b. Each lateral or overhead service drop originates from the same point of service.
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 requirements.
It allows more than six disconnects grouped at one location, without having to divide the structure
into multiple buildings by using area separation walls. This also allows designers more flexibility in
the placement of electrical meters and main service disconnects.
**Section 230-71(a) add an Exception.
230-71. Maximum Number of Disconnects.
(a) General. The service disconnecting means for each service permitted by Section 230-2, or for
each set of service-entrance conductors permitted by Section 230-40, Exception Nos. 1 or 3, shall
consist of not more than six switches or six circuit breakers mounted in a single enclosure, in a
group of separate enclosures, or in or on a switchboard. There shall be no more than six
disconnects per service grouped in any one location. For the purpose... {text unchanged} ...shall not
be considered a service disconnecting means.
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: The same reasoning as for multi-family dwellings in Section 230-2
here being applied to multi-occupant buildings.
*NOTE: Underlining indicates new words and phrases to be added to the 1999 National
Electrical Code. ~tril~€sxts indicate existing words and phrases to be deleted.
99 NEC 1 of 3 7/16/99
**Section 250-50 add a fifth paragraph.
250-50. Grounding Electrode System. If available on the premises at each building or structure
served, each item (a) through (d), and any made electrodes...{text unchanged}...interconnect
electrodes that are part of the grounding electrode system.
Exception: In industrial ... {text unchanged} ...conductor is exposed.
Where a metal underground water pipe, as described in item (a), is not present, a method of
grounding as specified in (b) through (d) below shall be used.
(FPN): See Sections... {text unchanged} ... agriculture buildings.
REASON FOR CHANGE: Sometimes metal underground water pipe is not available for use as a
grounding electrode system. Therefore, to provide a more positive approach for grounding
electrical premise systems for safety, a method as specified in (b), (c), or (d) shall be used. This
will eliminate the need to depend solely on a driven rod or pipe as specified in Section 250-52.
.. . .. .,,,.,, .,,,,, .~:ns~t.. a~t~~•,~n;.~catis-ss.~~~i..t~., ;,~ s~~' ,a.a:
**Section 250-104(b) change to read as follows:
250-104. Bonding of Piping Systems and Exposed Structural Steel.
*(b) Metal Gas Piping. Each interior abeeund portion of a metal gas piping system upstream
from the equipment shutoff valve shall be electrically continuous and bonded to the grounding
electrode system. The bonding jumper shall be sized in accordance with Table 250-122 using the
rating of the circuit that may energize the gas piping.
REASON FOR CHANGE: The revisions further clarify what portions of the gas piping system
must be bonded. Without a revision to this section (depending on bond sizing chosen), it was
possible to violate Section 250-52(a), which prohibits using a metal underground gas piping
system as a grounding electrode. The sentence added gives guidance to proper sizing to ensure
the gas system will be brought to the same potential as a grounding electrode system when an
inspector perceives a reasonable possibility that the gas system may become energized.
**Section 310-15(b)(6) change to read as follows:
310-15. Ampacities for Conductors Rated 0 to 2000 Volts.
(b) Tables.
(6) 120/240-Volt, 3-Wire, Single-Phase Dwelling Services and Feeders. For dwelling
units, conductors, as listed in Table 310-15(b)(6), shall be...{text unchanged}...conductors. The
grounded conductor shall be permitted to be smaller than the ungrounded conductors, provided the
requirements of Sections 215-2, 220-22, and 230-42 are met. This Section shall not be used in
conjunction with Section 220-30.
REASON FOR CHANGE: To provide a more reasonable margin of safety for dwelling service
and feeder conductor allowable ampacities.
99 NEC 2 of 3 7/16/99
**Section 336-5(a)(1) add an Exception; Section 336-5(a) add a tenth restriction.
336-5. Uses Not Permitted.
(a) Types NM, NMC, and NMS. Types NM, NMC, and NMS cables shall not be used in the
following:
(1) In any multifamily dwelling or other structure exceeding three floors above grade
For the purpose of this article, the first floor of a...{text unchanged}...vehicle parking, storage,
or similar use shall be permitted.
Exception: An additional level shall be permitted in multifamily dwellings where the entire
structure is protected throughout by an approved automatic sprinkler system.
(2) As service-entrance cable.
10) In non-residential metal frame structures.
REASON FOR CHANGE: To allow a reasonable expansion for NM cable use in dwelling
occupancies, while somewhat limiting the use of NM cable in occupancies where it is more
vulnerable to physical damage and where use is somewhat limited by the NEC and building
codes. This allows nonmetallic sheathed cable as a wiring method in four story single or
multifamily dwellings provided they are fully sprinkled throughout the entire building. It allows
designers to be more cost effective in their designs of wiring methods.
