Carson FAQ
Do I need a permit for a 12-inch-deep inflatable pool?
No. California HSC § 115921 only regulates pools over 18 inches deep. Small inflatable kiddie pools below 18 inches do not require a permit, but you should still drain them when unattended.
My above-ground pool is 52 inches tall — does it meet the barrier requirement?
No. HSC § 115923 requires a 60-inch minimum enclosure. A 52-inch above-ground wall would need a supplemental fence or other approved SB 442 feature (such as a locking safety cover) to comply with HSC § 115922's two-feature minimum.
Can I put an above-ground pool in my front yard?
No. Carson's zoning chapter (CMC Article IX Ch. 1) treats pools as accessory structures, and accessory structures are prohibited in required front-yard setbacks in residential zones.
