Summary

Unincorporated San Diego County requires a pool enclosure at least 60 inches high measured on the side facing away from the pool, with no more than a 2-inch ground gap (4 inches over a solid deck) and no gaps passing a 1-3/4-inch sphere. Gates must open away from the pool and be self-closing and self-latching.

City-specific rules exist: Vista, Bostonia, Carlsbad, Encinitas, San Marcos, Chula Vista, El Cajon, Escondido, Oceanside, and San Diego have their own fencing & safety requirements rules that differ from San Diego County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

769, Sec. 3. (SB 552) Effective January 1, 2025.) 115922. (a) Except as provided in Section 115925, subject to subdivision (b), and consistent with Section 1596.814, when a building permit is issued for the construction of a new swimming pool or spa or the remodeling of an existing swimming pool or spa at a private single-family home, the respective swimming pool or spa shall be equipped with at least two of the following seven drowning prevention safety features: (1) An enclosure that meets the requirements of Section 115923 and isolates the swimming pool or spa from the private single-family home. (2) Removable mesh fencing that meets the ASTM International F2286 standard in conjunction with a gate that is self-closing and self-latching and can accommodate a key lockable device.

Full Breakdown

The County PDS 379 handout sets the enclosure standard for new pools, spas, and hot tubs in the unincorporated area. Enclosures (fence, wall, or other barrier) must be a minimum height of 60 inches, measured on the side of the enclosure that faces away from the swimming pool. The maximum vertical clearance from the ground to the bottom of the enclosure is 2 inches, which may be increased to 4 inches where the grade is a solid surface such as a concrete deck or where the enclosure is mounted on top of an above-ground pool structure.

Gaps or voids may not allow passage of a sphere 1-3/4 inches or greater in diameter; spacing between vertical members may increase up to 4 inches when the distance between the tops of horizontal members is 45 inches or more. The outside surface must be free of handholds or footholds that could let a child under five climb over. 5 gauge with mesh no larger than 2-1/4-inch square (1-3/4-inch square where separating the pool from the home). Pedestrian gates must open away from the pool and be self-closing with a self-latching device located at least 54 inches from the bottom of the gate. The barrier aligns with California's Pool Safety Act (Health & Safety Code 115922/115923).

Violations & Fines

Non-compliant or missing barriers fail the pre-plaster inspection and must be corrected before the pool can be filled. Inadequate gate latching or excessive gaps are common deficiencies that block approval and can trigger code-enforcement action.
