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

Del Norte County applies the California Residential Code (part of the Title 24 California Building Standards Code) to above-ground pools in the unincorporated areas; no county-specific above-ground pool ordinance was located in the County Code or Community Development materials. Under the statewide code, prefabricated or above-ground pools are treated like other pools once they reach the regulated depth. The California Residential Code generally exempts very shallow, temporary prefabricated pools (those not exceeding 24 inches deep) from a building permit, but a hard-plumbed or hard-wired above-ground pool, or one deeper than that threshold, requires a building permit from the county Building Inspection Division. Whenever a permit is issued for a new above-ground pool or spa at a single-family home, the California Swimming Pool Safety Act (Health and Safety Code section 115922) requires at least two of seven approved drowning-prevention features, the same as for in-ground pools. Many owners use the pool wall itself as part of the barrier, but the access ladder or steps must be removable or secured, and any attached deck or door providing direct access must meet the self-closing/self-latching or alarm requirements of the Act. Electrical bonding and grounding under the California Electrical Code also apply to above-ground pools with pumps and heaters. Because the county defers to state law, the practical takeaway is that an above-ground pool is not automatically exempt: depth, plumbing, and electrical connections determine whether a permit and the state safety features are required. Confirm the depth threshold and submittal items with the Del Norte County Building Inspection Division before installing.
