Riverside / Inland Empire at a Glance
The State Floor: Two of Seven Features
Underneath every local rule sits California's Swimming Pool Safety Act, Health and Safety Code (HSC) sections 115920 to 115929. For a new or remodeled pool or spa at a single-family home, HSC 115922 requires two of seven features: an isolating enclosure; ASTM International (ASTM) F2286 removable mesh with a lockable, self-closing gate; an ASTM F1346-23 safety cover; exit alarms on doors and windows to the pool; self-closing door hardware released at 54 inches or higher; an ASTM F2208 pool alarm; or a lab-verified equivalent.
On its own, the state rule does not require a fence. The City of Riverside and unincorporated Riverside County both do, as the next sections explain. An enclosure used as a state feature must meet HSC 115923: 60 inches high, 2 inches or less at the ground, and gates that open away from the pool with a latch at 60 inches or more.
City and County Barrier Rules
City of Riverside. The city's R-3 pool barrier handout says a pool must be surrounded by a barrier at least 60 inches high with no more than 2 inches at the ground, under Riverside Municipal Code (RMC) 16.19.020 and California Building Code (CBC) 3109.4.1. Openings cannot pass a 4-inch sphere; closely spaced horizontal rails go on the pool side; chain link needs 1¼-inch mesh (or slats down to 1¾ inches) and 11-gauge wire; pedestrian gates self-close, self-latch and open away from the pool. The two state features apply on top, and the fence and gates are inspected before the pool is filled.
Unincorporated Riverside County. The county's rule is now County Code Chapter 8.28, which carries forward Ordinance 421. The county's barrier agreement letter (revised December 2025), which still cites Ordinance 421, requires two compliant barriers installed, inspected and approved before plaster or fill:
- Primary: a compliant wall or fence at least 5 feet high isolating the pool, with exit door alarms where a house wall forms part of it. Removable mesh cannot be the primary barrier.
- Secondary: an ASTM F1346 cover, an ASTM F2208 pool alarm, ASTM F2286 mesh set at least 3 feet from the water, or a lab-verified equivalent.
- Details: chain link of at least 11 gauge, no larger than 2¼-inch mesh, tensioned top and bottom; wire or critter fencing not accepted; no pet door with direct pool access; door alarms that sound within 7 seconds at 85 dBA for at least 30 seconds, with a bypass at 54 inches or higher.
- Exemption: a self-contained spa or hot tub with a listed ASTM F1346 cover.

Frequently Asked Questions
Riverside Pool Fencing: Find Your Line First
Inside the City of Riverside, plan on a 60-inch barrier plus two state features. In unincorporated county territory, plan on a 5-foot primary enclosure and a secondary feature, with mesh only as the second layer. In the other cities, the state rule is the floor and each city decides what it adds.
Confirm which of those applies to your address before you order fencing, then design the barrier and the second feature together.
