Summary
In the City of Placentia, California, a building permit for a new or remodeled swimming pool or spa at a private single-family home requires an enclosure that isolates the pool and spa from the house, plus at least one additional drowning prevention feature. Placentia Municipal Code § 20.08.050 revises CRC Appendix CI, Section CI100, to say so.
(c) CRC Appendix CI, Section CI100 is revised to read as follows: (a) Except as provided in Section CI100, 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 item #1 below AND at least one additional following seven drowning prevention features: #1. An enclosure that meets the requirements of CI100 and isolates the swimming pool and spa from the private single-family home. Any walls of the residential structure or accessory structures used to complete the isolation enclosure must have door openings equipped with protection as required in CI100. Any such door(s) and window(s) protection device provided for this purpose may not be used to comply with the second drowning prevention feature requirement.
Full Breakdown
Section 20.08.030 adopts the 2025 California Residential Code for the City of Placentia, expressly including Appendix CI (Swimming Pool Safety Act). Section 20.08.050(c) then revises Section CI100 by ordinance O-2025-11, dated 11/18/2025.
The trigger is a building permit. When one is issued for the construction of a new swimming pool or spa, or the remodeling of an existing one, at a private single-family home, the pool or spa must carry item #1 and at least one additional drowning prevention feature from a list of seven. Item #1 is an enclosure that meets CI100 and isolates the swimming pool and spa from the home. Where walls of the residential structure or of accessory structures complete that isolation enclosure, their door openings must be equipped with the protection CI100 requires. The door and window protection devices provided for the enclosure cannot also be counted toward the second drowning prevention feature.
The city's printed text names seven additional features but does not list them, and it does not reproduce gate or barrier specifications, so those details are not stated on this page. Where the California Code of Regulations and the State Building Standards Code differ from the Placentia Residential Code, the state regulations prevail except as specifically modified (§ 20.08.030). The city building official or a designee enforces the Residential Code (§ 20.08.060), fees are set by city council resolution under California Government Code § 66016 (§ 20.08.070), and a copy of the 2025 California Residential Code is on file in the building official's office (§ 20.08.080). Pool permits themselves are covered on the separate pool permit page.
Violations & Fines
Work begun without the required permit carries a penalty equal to 100% of the fee for the requisite permit if the permit is issued after the work commences (§ 20.08.070), charged in addition to the permit fees the city council sets by resolution. The building official or a designee enforces the Residential Code (§ 20.08.060), and walls or doors that do not isolate the pool from the home do not meet item #1.
