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.
