Newport Beach, CA Swimming Pools & Spas: Hot Tub Rules (2026)

Permanent hot tub and spa installations in Newport Beach require a building permit and electrical permit from the Building Division. The California Building Code requires pool barriers for spas, but ASTM F1346-compliant safety covers that can support a minimum of 485 pounds serve as an acceptable barrier alternative when kept locked when not in use. Spas must be set back from property lines according to the applicable zoning district, typically a minimum of 3 feet. Electrical installations require GFCI protection on all circuits, proper equipment bonding per NEC Article 680, and a disconnect switch within sight of the spa. Gas-fired spa heaters require plumbing permits and must comply with the California Mechanical Code. Noise from spa pumps, jets, and heaters must comply with NBMC noise standards, which limit residential equipment noise to 55 dBA at the property line during daytime and 50 dBA at night. Spas within the Coastal Zone may require additional review. Water discharge from spa draining must go to the sanitary sewer, not storm drains. The Building Division at (949) 644-3200 processes spa permit applications.
