Norwalk, CA Swimming Pools & Spas: Fencing & Safety Requirements (2026)

Norwalk pool enclosures answer to two grounded sources. Health and Safety Code Section 115923 sets the technical specifications for any enclosure used to satisfy the state's Swimming Pool Safety Act: access gates must open away from the pool and be self-closing with a self-latching device mounted no lower than 60 inches above the ground, the enclosure itself must stand at least 60 inches tall, the gap between the ground and the bottom of the enclosure cannot exceed 2 inches, no gap or void in the barrier can pass a 4-inch sphere, and the outside surface must be free of protrusions, cavities or other features a child under five could use to climb over.

175 splits the rule by pool type. Public swimming pools must be completely enclosed by a fence at least 5 feet high or a screen enclosure, with no opening large enough to pass a 4-inch sphere, and the fence or screen must have self-closing, self-latching gates; Building Code Chapter 31B adds further public-pool requirements. Private pools and spas at single-family homes, new or remodeled, must instead have an enclosure that complies with the amended California Residential Code, Appendix CI, which is where the state's enclosure specifications from Section 115923 are carried into the building permit process. 120 will not sign off on a pool, or allow it to be filled with water, until the fencing has passed.
