Hot tubs and spas in South Gate require a building permit regardless of depth under California Residential Code §R105.1 (adopted via South Gate Municipal Code Chapter 9.02). California Health and Safety Code §115921(b) exempts a hot tub or spa from the SB 442 two-feature rule ONLY if it is equipped with a 'safety cover' meeting ASTM F1346 - a locking, manually or power-operated cover designed to prevent unintended entry. Without that locking cover, the spa is subject to the same two-feature drowning-prevention requirements as a pool. Pool/spa-equipment noise must comply with South Gate Municipal Code Chapter 7.44 (Noise) and Chapter 11.34 (Noise Control Program).
