SOMMERVELL, TARRANT and WISE counties are classified as Warm Humid
(Reason: This amendment is added to satisfy the "not less restrictive" requirement when adopting
subsequent editions of energy codes in accordance with Texas SB 5, 77th Legislature. Also
eliminated data not applicable in North Central Texas. )
***Amend Section N1102.1 Insulation and fenestration criteria, to read as follows:
1102.1 Insulation and fenestration criteria. The building thermal envelope shall meet
the requirements of Table N1102.1 based on the climate zone specified in Table
N 1101.2.
When compliance usina Table 1102.1 is demonstrated with a ceiling R-value of R30 or
less, no more than 33% of the total projected ceiling area may be of cathedral type
construction (ceiling ioist/roof rafter assembly) and the reauired insulation R-value may be
reduced to a minimum of R22 insulation when the remainina ceiling area insulation is
increased to R38.
(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.)

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-existing fences. The installation of a swimming pool creates the
requirement for the barrier fence. A previously existing 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 general
rule is when the fence on one side of the new pool is already a pool enclosure
for the adjacent property. That fence segment which is common to another yard
with a pool is a legal nonconforming pool enclosure and need not be upgraded.
Any other existing fence that is lust now becoming 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
23
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(102 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 height, 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 inches (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 aself-latching device. Gates other than pedestrian access shall "~~~° ~ °°~f
e-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 gates designed or intended to be used on a regular basis may be
automatic closing rather than maintained locked. Automatic pates may be opened
by a key or switch (fixed or remote) but the pate shall automatically close within
one to two minutes without requiring 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:
9.1. 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,
24
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 AG105.2, 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.)
***Appendix P; Amend section AP 101 and add AP101.1 as follows:
AP101 Fire sprinklers. An approved automatic fire sprinkler system shall be installed in
new one- and two-family dwellings and townhouses in accordance with Section 903.3.1 of
the International Building Code.
EXCEPTION: Dwellings containing less than 6000 square feet enclosed space.
For upper level attic type rooms, areas where the ceiling height is less than five
feet (5' 0") shall not be considered. Unfinished space framed to permit future
expansion of floor area shall be considered as part of the area. Joists designed to
support floor loads shall be assumed to be for future area. (living area plus
garages and any other enclosed spaces but not open porches or patios).
AP101.1 Existing dwellings. An approved automatic fire sprinkler system shall be
installed in existing dwellings in accordance with Section 903.3.1 of the International
Building Code when the existing dwelling plus the proposed addition exceeds 6000
square feet enclosed space (living area plus garages and any other enclosed spaces but
not open porches or patios).
Exception: Existing unfinished space under roof (e.q. bonus space in attic) may
be converted to living area unless the existing dwelling is already sprinklered, then
the protection shall be extended to include the new area.
END OF AMENDMENTS.
