Lake Forest, CA Swimming Pools & Spas: Safety Rules (2026)

Lake Forest administers the California Swimming Pool Safety Act (Health and Safety Code Sections 115920-115929) when issuing pool permits; the city's Building Permits page lists a 'Swimming Pool Barrier Fencing' handout that references the Pool Safety Act. Under Section 115922, whenever a building permit is issued to construct a new pool or spa, or to remodel an existing one, at a single-family home, the pool must be equipped with at least two of seven drowning-prevention safety features: (1) an isolation enclosure separating the pool from the home; (2) removable mesh fencing meeting ASTM F2286 with a self-closing, self-latching, key-lockable gate; (3) an approved safety pool cover meeting ASTM F1346; (4) exit alarms on doors and windows with direct pool access; (5) a self-closing, self-latching device with a release no lower than 54 inches on doors giving direct pool access; (6) a pool alarm that detects entry into the water; or (7) another approved device meeting equivalent standards. Beyond construction, the city's Property Maintenance Code (Chapter 6.12) requires pool and spa water to be kept clean and clear, free of algae, insects, and debris, and barriers and gates to be maintained per the California Residential Code. Lake Forest's contribution is permit review, inspection, and maintenance enforcement; the substantive safety requirements are state law.
