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

), as amended effective January 1, 2018, requires that every new or substantially remodeled residential pool or spa at a single-family home include at least two of seven approved drowning-prevention safety features. Per the City of Napa's pool page, the seven options are: (1) an enclosure isolating the pool from the home meeting H&S 115923; (2) removable mesh fencing meeting ASTM F2286 with a self-closing, self-latching, key-lockable gate; (3) an approved automatic safety cover meeting ASTM F1346 (H&S 115921(d)); (4) exit alarms on doors providing direct access to the pool; (5) self-closing, self-latching devices on those doors with release at least 54 inches above the floor; (6) an alarm in the water meeting ASTM F2208; or (7) any other independently verified equivalent safeguard.

Where an enclosure is one of the chosen features, H&S 115923 requires it to be at least 60 inches high with a maximum 2-inch ground clearance, no openings allowing passage of a 4-inch sphere, no climbable handholds or footholds, and a self-closing self-latching gate that opens away from the pool with the latch at least 60 inches above the ground.
