Dublin, CA Swimming Pools & Spas: Fencing Requirements (2026)

Dublin's 'Swimming Pools, Spas, Hot Tubs' handout states the fence must be non-climbable and a minimum of five feet high, measured from the outside, with self-closing and self-latching gates; the dwelling may form part of the enclosure but then pool alarms are required on doors. A separate pre-plaster inspection verifies the barrier (fence, gates, door alarms) before the pool is filled with water. These local rules implement the California Swimming Pool Safety Act, which controls statewide. California Health & Safety Code Section 115923 requires an enclosure at least 60 inches high measured on the outside, a maximum 2-inch gap at grade, no openings that pass a 4-inch sphere, and gates that open away from the pool with self-latching hardware mounted at least 60 inches above grade (or otherwise out of a child's reach). For new and remodeled pools, HSC Section 115922(a) requires at least two of seven approved drowning-prevention features. Dublin applies these through the California Residential Code (Appendix AX) and verifies them at the barrier inspection.
