In unincorporated San Diego County, a prefabricated above-ground pool less than 18 inches deep and under 5,000 gallons is exempt from a building permit. Deeper or larger above-ground pools require a County permit and must meet the CA Pool Safety Act barrier rules.
San Diego County PDS applies the California Residential Code permit exemption: a prefabricated pool accessory to a single-family home that is installed entirely above ground, less than 18 inches deep, and no more than 5,000 gallons does not require a building permit. Any above-ground pool exceeding those thresholds needs a permit and, once permitted, must include at least two of the seven Health & Safety Code 115922 drowning-prevention features. Even permit-exempt pools should be secured against unsupervised child access. Electrical connections for pumps and heaters still require permits and inspection.
Installing a permit-required above-ground pool without approval can lead to stop-work orders and code-enforcement penalties until corrected or permitted.
