Del Norte County, CA Swimming Pools & Spas: Hot Tub Rules (2026)

Del Norte County did not appear to enact a hot-tub-specific ordinance, so spas and hot tubs in the unincorporated areas are regulated by the adopted California Building Standards Code (Title 24) and the California Swimming Pool Safety Act. Under California law, a spa or hot tub is treated as a body of water at the regulated depth, and a self-contained, hard-wired or hard-plumbed spa generally requires a building or electrical permit for the electrical connection, bonding, and grounding under the California Electrical Code, even when the unit is a packaged factory product. When a building permit is issued for a new or remodeled spa at a single-family home, Health and Safety Code section 115922 requires at least two of seven drowning-prevention features. For spas, the most common compliance path is an approved safety cover meeting ASTM F1346 combined with a second feature such as exit-door alarms or self-closing, self-latching access doors; the safety cover is expressly listed among the seven features. Portable, plug-in spas that include a listed locking safety cover are often the simplest to permit, but the electrical supply still must comply with the code, and a dedicated GFCI-protected circuit is typically required. Because the county follows state law, applicants should confirm with the Del Norte County Building Inspection Division whether their specific spa requires a permit and which two safety features they intend to use. Public and community spas (apartment, HOA, hotel) are additionally regulated by the county Environmental Health Division under California Code of Regulations Title 22, which sets drain-cover, recirculation, temperature, and signage standards.
