Summary
Residential pools and spas in unincorporated Butte County must comply with California Health and Safety Code section 115922 et seq., which requires installation of at least two of seven approved drowning prevention safety features at the time of construction or remodel; the most common option is a 60-inch-tall isolation enclosure with a self-closing, self-latching gate that swings away from the pool.
(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
Butte County does not have a county-specific swimming pool fencing ordinance. Pool barriers in unincorporated Butte County are governed by the California Swimming Pool Safety Act (Health and Safety Code sections 115920-115929) and the California Building Standards Code, which the Butte County Department of Development Services adopts and enforces through the Building Division. Under HSC section 115922, a new or remodeled residential pool or spa must be equipped with at least two of seven drowning prevention features: an isolation enclosure meeting HSC 115923; removable mesh fencing meeting ASTM F2286; a manual or power-operated safety pool cover meeting ASTM F1346-23; exit alarms on the home's doors and windows providing direct access to the pool; a self-closing, self-latching device on doors providing direct access, with a release no lower than 54 inches above the floor; an alarm in the water that sounds upon entry; or other approved means of equal or greater protection.
When an isolation enclosure is used, HSC section 115923 requires a minimum 60-inch height, a maximum 2-inch vertical clearance between the ground and the bottom of the enclosure, no openings that allow passage of a 4-inch sphere, an exterior free of handholds or footholds, a gate that opens away from the pool, and a self-closing gate with a self-latching device placed no lower than 60 inches above the ground. The act applies only to single-family residential pools and spas; apartments, public pools, and hot tubs with locking ASTM F1346-compliant covers are exempt under HSC section 115925.
Violations & Fines
Failure to install the required drowning-prevention features will prevent final inspection sign-off and certificate of occupancy from the Butte County Building Division. Unpermitted pools or pools that fail to comply with HSC 115922/115923 are unsafe building conditions that can trigger Code Enforcement action under the California Building Code and county code enforcement procedures, including stop-work orders, abatement, and civil penalties. In a drowning incident, noncompliance also creates substantial civil liability.
