N1101.2.1 Detached one- and two-family dwellings.
Compliance shall be demonstrated by either:
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; or
2 Meeting the requirements of the International Energy Conservation Code for detached one- and two-family
dwellings~
3. Meetinq the requirements of this chapter for buildinqs with a qlazinq area that is qreater than 15 percent
but not exceedinq 20 percent of the qross area of exterior walls and air conditioninq equipment rated 12 SEER
or hiqher; or
4. Meetinq the requirements of this chapter for buildinqs with a qlazinq area that is qreater than 20 percent
but not exceedinq 25 percent of the qross area of exterior walls and air conditioninq equipment rated 14 SEER
or hiqher.
(Reason: This amendment increases the number of builders who could use this "simplified
prescriptive" approach of the IRC. The trade-off with air-conditioning is an option under the IECC
systems analysis or REScheck 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:
N11 01.3.4 Exterior basement or slab insulation. When susceptibility to termite damaqe is classified as
"very heavy" accordinq to Table R301.2(1), desiqns employinq basement or slab exterior insulation capable of
harborinq 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 the area-weighted
average maximum required fenestration U-factor (other than opaque doors which are governed by Section
N11 02.13) 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 N11 02.1.
Detached one-and-two family dwellings with greater than 4-á-25-percent glazing area; townhouses with greater
than 25-percent glazing area; and any residential building in climates 'Nith heating degree days equ:::¡1 to or
greater th:::¡n 13,000; shall determine compliance using the building envelope requirements of Chapters 4 or 5
of the International Energy Conservation Code.
(Reason This amendment is compatible with the amendment to Section N11 01.2.1, which increases the
allowable glazing area and effectively increases the number of builders who can use the "simplified
prescriptive" approach of the IRC.)
Replace Table N1102.1 with:
TABLE N1102.1

SIMPLIFIED PRESCRIPTIVE BUILDING ENVELOPE THERMAL COMPONENT CRITERIA
MINIMUM REQUIRED THERMAL PERFORMANCE (U-FACTOR AND R-VALUE)
a. Crawl space insulation is only required for structures with uninsulated floors.
Use of this table is limited to projects where the cathedral ceiling area is limited to one third or less of the total
ceiling area.
(Reason: These numbers are from the tables in the code for the climate data of the Dallas/ Ft. Worth
area. 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 N1102.1.6; delete last sentence of exception.
(Reason: Slab edge insulation is not recommended in this region. Deleting the last sentence of the
exception allows the use of the simplified prescriptive method of compliance.)
Section N1102.2; add exceptions 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 locations with 3,500 or fewer heating degree
days shall not exceed 0.40.
Exceptions:
1. Any QlazinQ facinQ within 45 deQrees of true north;
2. Any QlazinQ facinQ within 45 deQrees of true south which is shaded alonQ its full width by a
permanent overhanq with a proiection factor of 0.3 or Qreater.
3. Any fenestration with permanently attached screens where the screens have a rated shadinQ
coefficient of .6 or less.
(Reason: This will allow north facing windows, which do not receive direct solar radiation, to be
exempt from the minimum SHGC requirement; provides a simple way for south facing windows to
effectively achieve summer shade and still receive some solar heat benefit in winter; and specifically
allows use of solar screens to achieve the shading effect.)
Table N1103.5; amend as follows:
Amend footnote "b" to read as follows:
b. For piping lenqths in excess of five (5) feet (1,524 mm) exposed to outdoor air, increase thickness
by 0.5 inch (13 mm).
(Reason: No performance data is available. REM/Rate scoring procedures do not c~ns.ider
refrigerant piping insulation. This amendment will provide a uniform approach and eliminate the
requirement of policies by the various jurisdictions.)
Add Section M1304.2 to read as follows:
M1304.2 Minimum burial depth, Underqround fuel pipinq systems shall be installed a minimum depth of 18
inches (458 mm) below qrade.
(Reason: Appropriate protection consistent with area practice.)

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. Consistent with regional
amendments to IMC 306.3 and IFGC 306.3.)

Sections P3105.2; change to read as follows:
P3105.2 Fixture drains. The total fall in a fixture drain due to pipe slope shall not exceed one pipe diameter,
nor shall the vent pipe connection to a fixture drain, except for water closets, be below the weir of the trap,
except 3S provided in Section P3105.3.
Section P3105.3 and Figure P3105.3; delete
(Reason: S traps may siphon dry allowing sewer gas into building.)
Section P3111.1; change to read as follows:
P3111.1 Type of fixture. A combination waste and vent system shall not serve fixtures other than floor drains,
standpipes, sffik&-and lavatories indirect waste receptors. Combination drain and vent systems shall not
receive the discharqe of a food waste qrinder.
(Reason To prevent trap siphoning of sinks and lavatories.)
Section P3111.2; change to read as follows:
P3111.2 Installation. The only vertical pipe of a combination drain and vent system shall be the connection
between the fixture drain of a sink, 13v:Jtory or standpipe, and the horizontal combination waste and vent pipe.
The maximum vertical distance shall be 8 feet (2438 mm).
(Reason To prevent trap siphoning of sinks and lavatories.)
Sections P3112.2 and3112.3 ;delete and replace with new Section 3112.2 as follows:
P3112.2 Installation. Traps for island sinks and similar equipment shall be rouqhed in above the floor and
may be vented by extendinq the vent as hiqh as possible, but not less than the drainboard heiqht and then
returninq it downward and connectinq it to the horizontal sink drain immediately downstream from the vertical
fixture drain. The return vent shall be connected to the horizontal drain throuqh a wye-branch fittinq and shall,
in addition, be provided with a foot vent taken off the vertical fixture vent by means of a wye-branch
Immediately below the floor and extendinq to the nearest partition and then throuqh the roof to the open air or
may be connected to other vents at a point not less than six (6) inches (152 mm) above the flood level rim of
the fixtures served. Drainaqe fittinqs shall be used on all parts of the vent below the floor level and a minimum
slope of one-quarter (1/4) inch per foot (20.9 mm/m) back to the drain shall be maintained. The return bend
used under the drainboard shall be a one (1) piece fittinq or an assembly of a forty-five (45) deqree (0.79
radius), a ninety (90) deqree (1.6 radius) and a forty-five (45) deqree (0.79 radius) elbow in the order named.
Pipe sizinq shall be as elsewhere required in this Code. The island sink drain, upstream of the return vent,
shall serve no other fixtures. An accessible cleanout shall be installed in the vertical portion of the foot vent.
(Reason: To clarify the installation of island venting and to provide a standard installation method for
the region. An air admittance valves installed according to section 3114 is an alternate venting
method to this section.)
Part VIII- Electrical, Chapters 33 through 42; Delete and add note as follows:
Note: Chapters 33 throuqh 42 are based on the 1999 National Electrical Code and are included here for
reference only. The National Electrical Code as adopted by separate ordinance takes precedence over these
sections
Section E3301. 1; add a sentence to read as follows:
All references to NFPA 70 shall mean the Electrical Code as adopted.
Appendix G; Change section AG105 as follows:
AG105.2 Outdoor swimming pool. An outdoor swimming pool, including an
In-ground, aboveground or on-ground pool, hot tub or spa shall be provided
with a barrier which shall comply with the following:
1. The top of the barrier shall be at least 48 inches (1219 mm) above grade measured on the
side of the barrier which faces away from the swimming pool. The maximum vertical clearance
between grade and the bottom of the barrier shall be 2 inches (51 mm) measured on the side of
the barrier which faces away from the swimming pool. Where the top of the pool structure is above
grade, such as an aboveground pool, the barrier may be at ground level, such as the pool
structure, or mounted on top of the pool structure. Where the barrier is mounted on top of the pool
structure, the maximum vertical clearance between the top of the pool structure and the bottom of
the barrier shall be 4 inches (102 mm).
Pre-existina fences. The installation of a swimminq pool creates the requirement for the barrier
fence. A previously existinq fence would not have any status under this section because the
addition of the pool creates the hazard on which the code section is based. The one exception to
this qeneral rule is when the fence on one side of the new pool is already a pool enclosure for the
adjacent property. That fence seqment which is common to another yard with a pool is a leqal
nonconforminq pool enclosure and need not be upqraded. Any other existinq fence that is just now
becominq a pool enclosure shall comply with this section.
2. Openings in the barrier shall not allow passage of a 4-inch-diameter (102 mm) sphere.
3. Solid barriers which do not have openings, such as a masonry or stone wall, shall not contain
Indentations or protrusions except for normal construction tolerances and tooled masonry joints.
4. Where the barrier is composed of horizontal and vertical members and the distance between the
tops of the horizontal members is less than 45 inches (1143 mm), the horizontal members shall be
located on the swimming pool side of the fence. Spacing between vertical members shall not exceed
1.75 inches (44 mm) in width. Where there are decorative cutouts within vertical members, spacing
within the cutouts shall not exceed 1.75 inches (44 mm) in width.
5. Where the barrier is composed of horizontal and vertical members and the distance between the
tops of the horizontal members is 45 inches (1143 mm) or more, spacing between vertical members
shall not exceed 4 inches(1 02 mm). Where there are decorative cutouts within vertical members,
spacing within the cutouts shall not exceed 1.75 inches (44 mm) in width.
EXCEPTION: When horizontal members are part of a fence that is at least 6 feet (1830 mm) in
heiqht, the horizontal members need not be on the pool side of the barrier and the 45 inch distance
between horizontal members does not apply.
6. Maximum mesh size for chain link fences shall be a 2.25-inch (57 mm) square unless the fence is
provided with slats fastened at the top or the bottom which reduce the openings to not more than 1.75
nches (44 mm).
7. Where the barrier is composed of diagonal members, such as a lattice fence, the maximum opening
formed by the diagonal members shall not be more than 1.75 inches(44 mm).
8. Access gates shall comply with the requirements of Section AG105.2, Items 1 through 7, and shall
be equipped to accommodate a locking device. Pedestrian access gates shall open outward away
from the pool and shall be self-closing and have a self-latching device. Gates other than pedestrian
access shall h3'Je ;:¡ self 13tching devico be equipped with lockable hardware or padlocks and shall
remain locked at all times when not in use.
Where the release mechanism of the self-latching device is located less than 54 inches (1372 mm)
from the bottom of the gate, the release mechanism and openings shall comply with the following:
8.1. The release mechanism shall be located on the pool side of the gate at least 3 inches (76
mm) below the top of the gate, and
8.2. The gate and barrier shall have no opening greater than 0.5 inch (12.7 mm) within 18 inches
(457 mm) of the release mechanism.
Vehicle qates desiqned or intended to be used on a reqular basis may be automatic closinq rather
than maintained locked. Automatic qates may be opened by a key or switch (fixed or remote) but the
qate shall automatically close within one to two minutes without requirinq any additional action on the
part of the person who opened it.
9 Where a wall of a dwelling serves as part of the barrier one of the following conditions shall be met:
91. The pool shall be equipped with a powered safety cover in compliance with ASTM F1346; or
9.2. All doors with direct access to the pool through that wall shall be equipped with an alarm
which produces an audible warning when the door and its screen, if present, are opened. The
alarm shall sound continuously for a minimum of 30 seconds immediately after the door is opened
and be capable of being heard throughout the house during normal household activities. The
alarm shall automatically reset under all conditions. The alarm system shall be equipped with a
manual means, such as touchpad or switch, to temporarily deactivate the alarm for a single
opening. Such deactivation shall last for not more than 15 seconds. The deactivation switch(es)
shall be located at least 54 inches (1372 mm) above the threshold of the door; or
9.3. Other means of protection, such as self-closing doors with self-latching devices, which are
approved by the governing body, shall be acceptable so long as the degree of protection afforded
IS not less than the protection afforded by Item 9.1 or 9.2 described above
10. Where an aboveground pool structure is used as a barrier or where the barrier is mounted on top
of the pool structure, and the means of access is a ladder or steps, then:
10.1. The ladder or steps shall be capable of being secured, locked or removed to prevent access,
or
10.2. The ladder or steps shall be surrounded by a barrier which meets the requirements of
Section AG1 05.2, Items 1 through 9. When the ladder or steps are secured, locked or removed,
any opening created shall not allow the passage of a 4-inch-diameter (102 mm) sphere.
(Reason: To allow for special conditions while retaining essentially the same degree of safety.)
