Full Breakdown
Sec. 8-332(c)(2) requires permitted pools, ponds, and spas to be enclosed by fencing that can withstand 200 pounds of force from any direction and blocks any gap wider than six inches. A permanent in-ground pool needs a freestanding fence between 48 and 96 inches tall, set at least three feet from the water's edge, with a locking door or gate meeting the same height and structural rules. Above-ground pools can instead use a compliant deck-mounted fence, a 48-inch pool wall with access steps removed when not in use, or an equivalent option. Fencing is waived for pools with a locking solid cover, pools inside a building, and pools that predate April 20, 2004.
Violations & Fines
The Building Inspection Division can withhold or revoke a pool permit for noncompliant fencing, and an unfenced permitted pool is enforceable as a code violation subject to a written correction order.
