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

The Santa Cruz County Swimming Pool Enclosure Ordinance (SPEO) addresses above-ground pools specifically. For an above-ground pool, the top edge of the pool, or the top of any barrier mounted on top of the pool, must be at least 48 inches above ground level on all sides of the pool. In addition, the pool must either have a ladder or steps that can be secured, locked, or removed to prevent access, or be surrounded by a barrier meeting the standard SPEO enclosure features (60-inch height, restricted openings, self-closing/self-latching gates that swing away, and non-climbable design). A self-contained spa or hot tub with a listed safety cover is recognized as one acceptable barrier option. Like in-ground pools, an above-ground pool, spa, or hot tub that holds water over 18 inches deep is treated as a swimming pool under the California Building Code and County Code, so a building permit is required for installation, and the electrical layout must include a weatherproof GFCI receptacle between 10 and 20 feet of the water's edge. The County notes that on coastal-bluff sites, an above-ground pool, spa, or hot tub that fails could send large volumes of water over or into a coastal bluff, so additional site-specific requirements may apply. Above-ground pool installations are reviewed by the County's Community Development & Infrastructure department.
