Enclosures. Private swimming pools, hot tubs and spas,
containing water more than 24 inches (610 mm) in depth, shall be completely
surrounded by a fence or barrier at least 48 inches (1219 mm) in height
above the finished ground level measured on the side of the barrier
away from the pool. Gates and doors in such barriers shall be self-closing
and self-latching. Where the self-latching device is less than 54
inches (1372 mm) above the bottom of the gate, the release mechanism
shall be located on the pool side of the gate. Self-closing and self-latching
gates shall be maintained such that the gate will positively close
and latch when released from an open position of six inches (152 mm)
from the gatepost. No existing pool enclosure shall be removed, replaced
or changed in a manner that reduces its effectiveness as a safety
barrier.
