AV105.2 Outdoor swimming pool. An outdoor swimming
pool, including an in-ground, above-ground, or on-ground pool, hot
tub, or spa, shall be surrounded by a barrier which shall comply with
the following:

|
The top of the barrier shall be at least 48 inches (1,219 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 two 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 above-ground
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

or stone wall, shall not contain indentations or protrusions, except
for normal construction tolerances and tooled masonry joints.
| |

inches (1,143 mm) or more, spacing between vertical members shall
not exceed four inches (102 mm). Where there are decorative cutouts
within vertical members, spacing within the cutouts shall not exceed
1 3/4 inches (44 mm) in width.
