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

Above-ground pools in the unincorporated county are governed by the same provisions as in-ground pools. Under Non-Coastal Zoning Ordinance Sec. 8106-5.13, swimming pools, spas, hot tubs, and similar structures may be constructed to within 3 feet of rear and interior side lot lines, provided they do not intrude into a required front or street-side setback. Importantly, pools designed to hold less than 18 inches of water are exempt from these setback requirements, which covers many small or temporary above-ground and kiddie pools. Whether a building permit is required depends on the pool's construction and water depth: permanent or larger above-ground pools meeting the California Residential Code permit threshold require a Building and Safety permit, while small temporary pools below the depth threshold generally do not. Once a pool is deep enough to require a permit, it also falls under California's Swimming Pool Safety Act, meaning it must include at least two of the seven drowning-prevention features in Health and Safety Code Sec. 115922 (for above-ground pools, a removable ladder is not itself a listed substitute, so fencing, a power safety cover, or alarms are typically used). Electrical bonding and grounding for pumps and heaters is also reviewed under the adopted electrical code. Confirm depth, permit need, and required safety features with the Building and Safety Division before installation.
