Alhambra, CA Swimming Pools & Spas: Above-Ground Pools (2026)

Alhambra's zoning code does not create a separate, looser category for above-ground pools - Section 23.12.150 applies to swimming pools, spas and pool equipment generally, and the threshold for the safety and barrier requirements is a water depth of more than 18 inches that is not completely enclosed within a building. Most above-ground pools exceed that depth, so they are treated like in-ground pools for placement and safety. Pools, spas and pool equipment (including pumps) may not be located in a required front yard. In an interior side yard or rear yard they must sit at least three feet from any property line, and in a street side yard at least five feet from any property line, with all setbacks measured from the water line. A pool deeper than 18 inches must also comply with Municipal Code Chapter 9.52 and the city's Swimming Pool and Spa Code (Chapter 20.15), and a new pool at a single-family home must include the state-mandated drowning-prevention features under HSC 115922. Whether a building permit is required for a particular above-ground pool depends on its size and depth under the adopted construction code; the city's Building Division determines that and reviews the installation. Temporary, very shallow inflatable or wading pools at or under 18 inches deep generally fall outside the Section 23.12.150 safety thresholds, but owners remain responsible for child safety.
