If an isolation enclosure is selected as one of the two required SB 442 safety features, it must be at least 60 inches high with no more than a 2-inch gap from the ground (Cal. HSC §115923). Gates must be self-closing, self-latching, and open outward away from the pool, with the latch located at least 60 inches above the ground.

Hesperia FAQ
Does Hesperia have its own pool fence ordinance?
No standalone pool fence chapter is published in the Hesperia Municipal Code. The Building & Safety Division enforces Cal. HSC §115923 (60-inch enclosure standard) and the California Building Code under Title 24 CCR through the pool permit process under HMC Title 15.
Can I use chain-link fencing as a pool enclosure?
HSC §115923 requires openings small enough that a 4-inch sphere cannot pass through. Standard chain-link mesh exceeds this; you would need a fine-mesh insert or a different barrier type to comply.
Ontario FAQ
Is a standard 6-foot block wall enough for an Ontario pool?
The wall counts as one of the seven features, but the Act requires at least two. A second feature such as a door alarm or pool cover is also required.
Does my existing Ontario pool need to meet the new rules?
Existing pools are generally grandfathered, but remodel permits trigger full compliance with current H&S 115920 barrier and safety feature requirements.
