Alameda, CA Swimming Pools & Spas: Pool Permits (2026)

Pool and spa construction in Alameda is permitted and inspected by the city's Planning, Building and Transportation Department (Permit Center, 2263 Santa Clara Avenue, Room 190). Under the California Building Standards Code adopted by the city, any person who constructs, enlarges, alters, repairs, moves or installs electrical, gas, mechanical or plumbing systems must first obtain a permit; the city's 'When Is A Permit Needed?' guidance exempts only prefabricated swimming pools accessory to a one- or two-family dwelling that are less than 24 inches deep, do not exceed 5,000 gallons, and are installed entirely above ground. Because the California Building Code (§3109.2) and California Residential Code define a 'swimming pool' as any structure holding water more than 18 inches deep — expressly including hot tubs, spas and portable spas — virtually all in-ground pools, and any pool with permanent electrical or plumbing connections, require a permit regardless of depth. The city itself does not write the technical pool rules; it administers the statewide California Building Standards Code (Title 24) plus the Swimming Pool Safety Act. The Alameda zoning code separately governs where a pool may sit on the lot (see fencing/setback section). Contact the Permit Center to confirm the current code cycle, fees and submittal requirements.
