Summary
Above-ground and on-ground pools are treated the same as in-ground pools under Riverside County Ordinance 421 - any structure 18 inches or more deep needs a barrier and County permitting. Where the pool wall itself serves as the barrier and access is by a ladder or steps, the ladder must be securable, removable, or surrounded by a compliant 60-inch barrier.
Swimming Pool Safety Act [115920 - 115929] ( Article 2.5 added by Stats. 1996, Ch. 925, Sec. 3.5. ) 115920. This act shall be known and may be cited as the Swimming Pool Safety Act. (Added by Stats. 1996, Ch. 925, Sec. 3.5. Effective January 1, 1997.) 115921. As used in this article, the following terms have the following meanings: (a) “Swimming pool” or “pool” means any structure intended for swimming or recreational bathing that contains water over 18 inches deep. “Swimming pool” includes in-ground and aboveground structures and includes, but is not limited to, hot tubs, spas, portable spas, and nonportable wading pools.
Full Breakdown
Ordinance 421, Section 2 defines 'swimming pool' to include in-ground, aboveground, and on-ground swimming pools (and fixed-in-place wading pools) that are 18 inches or more in depth, regardless of whether water is present; 'above ground or on-ground pool' is cross-referenced to that definition. As a result, an above-ground pool 18 inches or deeper triggers the same barrier requirements as any other pool and is subject to County Building & Safety permitting under the adopted 2025 CRC. 6. When the ladder or steps are secured, locked, or removed, any opening created must still be protected by a compliant barrier.
The barrier handout notes the 2-inch maximum bottom clearance may be increased to 4 inches when the barrier is mounted on top of an above-ground pool structure.
Violations & Fines
An above-ground pool 18 inches or deeper left without a compliant barrier - or with a fixed, unsecured ladder that allows access - violates Ordinance 421, Section 3, which binds every owner, purchaser, lessee, tenant, or licensee in possession of the land. Installing one without the required permit and inspections is also a violation. Penalties follow Ordinance 725.
