Summary
Unincorporated Riverside County requires an enclosure barrier at least 60 inches high around outdoor pools and spas under Ordinance 421. The bottom gap may not exceed 2 inches (4 inches over a solid deck). Gates must be self-closing and self-latching, swing away from the pool, and meet latch-height rules. Chain link must be 11 gauge.
(a) Except as provided in Section 115925, subject to subdivision (b), and consistent with Section 1596.814, when a building permit is issued for the construction of a new swimming pool or spa or the remodeling of an existing swimming pool or spa at a private single-family home, the respective swimming pool or spa 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 ASTM International F2286 standard in conjunction with a gate that is self-closing and self-latching and can accommodate a key lockable device. (3) A manually operated or power-operated safety pool cover that is accompanied by a label verifying that the cover meets the specifications of the ASTM International F1346-23 standard. (4) Exit alarms on the private single-family home's doors and windows that provide direct access to the swimming pool or spa without any intervening enclosure. Whenever any door or window is opened or left ajar, exit alarms shall make either an audible, continuous alarm sound or a repeating verbal warning, such as a 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 in good repair and operable as designed that, when placed in a swimming pool or spa, will sound upon detection of accidental or unauthorized entrance into the water. The alarm shall meet and be independently certified to the ASTM International F2208 standard that includes surface motion, pressure, sonar, laser, and infrared type alarms. [...] (c) Before the issuance of a final approval for the completion of permitted construction or remodeling work, the local building code official shall inspect the drowning safety prevention features required by this section and, if no violations are found, shall give final approval.
Full Breakdown
1 (restated in Building & Safety form 284-004), an outdoor pool barrier must have its top at least 60 inches above grade measured on the side facing away from the pool, with no climbable structure within 3 feet horizontally that lowers effective height below 60 inches. Maximum bottom clearance is 2 inches, or 4 inches over a solid surface such as a concrete deck or atop an above-ground pool. Where horizontal members are spaced less than 45 inches apart, they must be on the pool side, and the outward face must be free of protrusions, indentations, or cutouts that make it climbable.
Openings may not pass a 1-3/4-inch sphere (increasable to a 4-inch sphere where vertical spacing is 45 inches or more). Chain link must be no less than 11 gauge, with a maximum 2-1/4-inch (per the 2025 handout) / 1-1/4-inch (Ord. 4) mesh per the more stringent standard. Pedestrian access gates must be self-closing, self-latching, and swing away from the pool. Where the latch release is below 54 inches, it must be on the pool side at least 3 inches below the gate top, with no opening over 1/2 inch within 18 inches of the release. Wire or 'critter' fencing must meet chain-link standards; mesh fencing is not allowed as a primary barrier.
Violations & Fines
An out-of-compliance barrier (too short, excessive gap, non-self-latching gate, climbable design) fails inspection and bars approval to fill the pool. For existing pools, possessing land with a non-compliant barrier violates Ordinance 421, Section 3, which applies to every owner, purchaser, lessee, tenant, or licensee. Enforcement and penalties follow Ordinance 725.
