Castro Valley FAQ
Do California pool safety rules apply to above-ground pools?
Yes, if water depth exceeds 18 inches. Above-ground pools meeting that threshold must satisfy the same drowning-prevention features required of in-ground pools when newly installed.
Are inflatable kiddie pools regulated?
Generally no. Pools holding water 18 inches deep or less fall outside the statutory definition and are not subject to the Swimming Pool Safety Act's barrier requirements.

Does my Intex pool need a permit?
If its design water depth exceeds 18 inches and it is installed for more than a season with filtration, yes. Small wading pools emptied daily are exempt.
Can I skip the fence if the pool is deep above ground?
Only if the walls meet 60 inches and the ladder is removed or locked. Otherwise a secondary barrier is still required under HSC 115922.
