Full Breakdown
020, layering city-specific enclosure rules on top of the state Swimming Pool Safety Act. 1 sets the physical dimensions: the top of the barrier must be at least 48 inches above grade on the side facing away from the pool, and the gap between grade and the bottom of the barrier cannot exceed 2 inches, or 4 inches where the barrier sits on top of an above-grade pool structure. 2, and where the barrier uses closely spaced horizontal and vertical members, the vertical spacing is capped at 1 3/4 inches; chain link mesh cannot exceed a 2 1/4-inch square unless slatted down to 1 3/4 inches.
4: any pedestrian access gate must swing outward away from the pool and be self-closing with a self-latching device, and where the release mechanism sits lower than 54 inches from the bottom of the gate, it has to sit on the pool side, at least 3 inches below the top of the gate, with no openings larger than half an inch within 18 inches of the release. 5 requires an alarmed door or an ASTM F1346-compliant power safety cover instead. 10 requires pool safety features and barriers to stay in place and remain fully functional.
Violations & Fines
Failing to install or maintain a compliant pool barrier, gate latch, or door alarm violates Section 3109 as amended, and removing a required safety feature violates the Section 3109.10 maintenance mandate directly. Violations are enforced as a misdemeanor under the citywide penalty at § 1.36.020, up to a $1,000 fine, six months in county jail, or both, and can trigger a stop-work or nuisance abatement action.
