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.

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.
Rancho Cucamonga FAQ
Does my 24 ft Intex pool need a permit?
If it holds water deeper than 18 inches, yes. Both the pool installation and electrical connection for the pump typically require permits under RCMC Title 15.
Can I keep my kiddie pool up all summer?
Small temporary pools under 18 inches are usually fine without permits, but you must drain and store them so they do not become an attractive nuisance for children.
