Santa Clara County, CA Swimming Pools & Spas: Above-Ground Pools (2026)

The County treats above-ground pools as swimming pools when they hold water deep enough to require a permit, so they are reviewed by the Department of Planning and Development under the same building code and zoning standards as in-ground pools. Zoning Ordinance Section 4.20.J requires the pool to sit at least five feet from any property line or right-of-way, measured to the interior wall, and the pool's filters and pumps must also be five feet from property lines. The drowning-prevention rules of the California Swimming Pool Safety Act (Health and Safety Code Sections 115922 and 115923) apply equally to above-ground pools. An above-ground pool's own rigid wall can serve as part of the required barrier if it is at least 60 inches high; where the wall is lower, or where a ladder or steps provide access, a compliant fence or a removable, lockable ladder/access control is needed so the overall barrier still blocks a 4-inch sphere and keeps children out. Because the Section 4.20.J note warns that fence-enclosure requirements may further limit placement where fence height is restricted to less than five feet, owners should confirm both setback and barrier compliance before installing. Temporary or inflatable wading pools below the permit threshold are generally not regulated as swimming pools, but standing water is still a drowning hazard.
