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.
Rialto FAQ
Can my house wall count as one side of the pool fence?
Yes, if doors leading to the pool have one of the SB 442 safety features (door alarm, self-closing/self-latching, or power safety cover).
Does a spa with a locking cover need a fence?
An ASTM F1346 listed safety cover can satisfy barrier requirements for a spa under CBC §3109, but a permit and inspection are still required.
