Above-ground pools holding water more than 18 inches deep are 'swimming pools' under Cal. HSC §115921(a) and are treated the same as in-ground pools by the Hesperia Building & Safety Division. A building permit is required under HMC Title 15, the pool must comply with the California Building Code/California Residential Code, and at least two of the seven SB 442 drowning prevention features must be installed. The pool wall itself (if 60+ inches high) may satisfy the enclosure requirement, provided ladders are removable or secured.

Fontana FAQ
Do inflatable kiddie pools need permits in Fontana?
No, small inflatable pools under the depth threshold are exempt. Permanent pools and larger structures require permits.
Can I put the pool next to my property line?
Setbacks typically match rear or side yard requirements; check with Planning for your zoning district.
Hesperia FAQ
Is a small inflatable pool exempt?
If it holds water 18 inches deep or less it falls outside HSC §115921(a). Anything deeper meets the statutory pool definition and triggers SB 442 safety requirements.
Can the pool wall serve as the fence?
Yes, if the wall is ≥60 inches and otherwise compliant with HSC §115923, the wall can satisfy the isolation enclosure feature. A second SB 442 feature is still required, and ladder access must be removable or secured behind a self-latching gate.
