Summary
Fullerton has locally amended California's Swimming Pool Safety Act through FMC 14.04.150 and 14.04.160, requiring every new or remodeled single-family pool or spa to have a 60-inch isolation enclosure (mandatory) PLUS at least one additional drowning-prevention feature - a stricter standard than the state default, which only requires any two of seven features.
(a) Except as provided in Section 115925, whenever a building permit is issued for the construction of a new swimming pool or spa, or any building permit is issued for remodeling of an existing pool or spa, at a private single-family home, it shall be equipped with at least two of the following seven drowning prevention safety features: (1) An enclosure that meets the requirements of Section 115923 and isolates the swimming pool or spa from the private single-family home. (2) Removable mesh fencing that meets the American Society for Testing and Materials (ASTM) International Specifications F2286 standards in conjunction with a gate that is self-closing and self-latching and can accommodate a key lockable device. (3) An approved safety pool cover, as defined in subdivision (d) of Section 115921. (4) Exit alarms on the private single-family home's doors that provide direct access to the swimming pool or spa. The exit alarm may cause either an alarm noise or a verbal warning, such as a repeating notification that 'the door to the pool is open.' (5) A self-closing, self-latching device with a release mechanism placed no lower than 54 inches above the floor on the private single-family home's doors providing direct access to the swimming pool or spa. (6) An alarm that, when placed in a swimming pool or spa, will sound upon detection of accidental or unauthorized entrance into the water. (7) Other means of protection, if the degree of protection afforded is equal to or greater than that afforded by any of the features set forth above and has been independently verified by an approved testing laboratory.
Full Breakdown
California's Swimming Pool Safety Act (Health and Safety Code sections 115920-115929) sets statewide minimum barrier requirements for residential pools and spas. 150 amends HSC 115922(a) so that, instead of allowing any two of the seven drowning-prevention features, the city requires Item #1 (a code-compliant isolation enclosure) PLUS at least one additional feature from the remaining list (removable mesh fencing meeting ASTM F2286, an ASTM F1346-23 safety cover, exit alarms on the home's doors, self-closing/self-latching door devices with a release at least 54 inches high, a water-detection alarm in the pool, or other equivalent independently-verified protection).
160 further amends HSC 115923 to require, among other things, that any access gate be self-closing with a self-latching device placed no lower than 60 inches above the ground, that no opening allow passage of a 4-inch sphere, and that the barrier maintain a minimum 3-foot-wide walking path between the barrier and the water. Walls of the residence or accessory structures used to complete the isolation enclosure must have door openings protected by an exit alarm or a self-closing/self-latching device, and that door protection cannot also be counted as the second drowning-prevention feature.
The state baseline still applies: minimum 60-inch barrier height, no more than 2 inches of clearance under the bottom, climb-resistant exterior, and a gate that opens away from the pool.
Violations & Fines
Construction or remodel work that does not meet the FMC 14.04.150 enclosure-plus-one-feature standard cannot pass Fullerton Building & Safety final inspection. Code Enforcement (714-738-6553) can cite owners under Title 14, and an unenclosed pool is independently a public nuisance under FMC 6.01.030, subjecting the property to abatement and administrative citations. In a drowning incident, noncompliance creates significant civil liability under California negligence-per-se principles.
