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.

Chino FAQ
Does a 12-inch kiddie pool require a permit?
No. Cal. HSC §115921 caps the definition at over 18 inches of water depth. Shallower wading pools are exempt from the Swimming Pool Safety Act.
Can I place an above-ground pool right at the property line?
No. Chino Municipal Code Title 20 (Zoning) sets rear and side-yard setbacks for accessory structures. Verify the residential zone setback with the Chino Planning Division before installation.
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.
