Carson, CA Fence Regulations: Pool Barriers (2026)

Under Cal. Health & Safety Code §115922 (effective Jan 1, 2018 as amended by SB 442), whenever a building permit is issued for construction of a new pool/spa or remodeling of an existing one at a single-family home, the pool/spa must be equipped with at least TWO of seven approved drowning-prevention safety features: (1) an isolation enclosure meeting §115923; (2) removable mesh fencing meeting ASTM F2286 with a self-closing/self-latching key-lockable gate; (3) an ASTM F1346-compliant safety pool cover; (4) exit alarms on doors/windows opening to the pool area; (5) a self-closing, self-latching device on doors to the pool area with release ≥54 inches above floor; (6) an ASTM F2208-compliant water alarm; or (7) other independently certified equivalent protection. Prohibited combinations exist (e.g., exit alarm + door latch cannot be paired). Under HSC §115923, an isolation enclosure must be at least 60 inches high, with maximum 2-inch gap at the bottom, gaps small enough to block a 4-inch sphere, no climbable footholds, and gates that open outward (away from the pool) and are self-closing with self-latching device 60+ inches above ground. Carson Building & Safety reviews these features as part of pool permit plan check; the LA County Department of Public Health pool program enforces public/commercial pool safety. Civil Code §3342.5 imposes strict liability on owners of certain dog breeds at unsecured pools (related but distinct).
