Summary
In the City of Placentia, California, the only swimming pool exempt from the building permit is a prefabricated pool accessory to a Group R-3 occupancy that is less than 18 inches deep, does not exceed 5,000 gallons and is installed entirely above ground. Any other pool falls under the Placentia Building Code permit requirement, enforced by the city building official.
105.2 Work Exempt from Permit. Exceptions 2, 9 and 14 shall read as follows: ... 9. Prefabricated swimming pools accessory to a Group R-3 occupancy that are less than 18 inches deep, do not exceed 5,000 gallons and are installed entirely above ground.
Full Breakdown
Chapter 20.04 of the Placentia Municipal Code adopts the 2025 California Building Code as the "Placentia Building Code" for the City of Placentia in Orange County (§§ 20.04.010 and 20.04.030). Section 20.04.050 then rewrites item 105.2, the list of work exempt from permit. Exception 9 is the only pool exemption, and every part of it has to be true: the pool is prefabricated and accessory to a Group R-3 occupancy, it is less than 18 inches deep, it does not exceed 5,000 gallons, and it is installed entirely above ground. An in-ground pool fails the "entirely above ground" condition, so it is outside the exemption.
The building official or a designee enforces the code (§ 20.04.060), and section 103.1 as amended in § 20.04.050 creates the Building and Safety Services Department with the building official in charge. Permit fees are set by city council resolution under California Government Code § 66016 (§ 20.04.070). A pool at a private single-family home carries a second layer of rules: § 20.08.050 revises CRC Appendix CI, Section CI100, so a building permit issued for a new or remodeled pool or spa brings drowning-prevention requirements, covered on the separate pool fencing page.
The building permit is also the single entry point for the excavation. Under § 20.40.090, a grading permit is not required for construction of swimming pools authorized by a valid building permit issued by the chief building official. Other grading on the lot still follows Chapter 20.40, where the city engineer issues grading permits (§ 20.40.080). Where the California Code of Regulations and the State Building Standards Code differ from the Placentia Building Code, the state regulations prevail except as the chapter specifically modifies them (§ 20.04.030).
Violations & Fines
Starting pool work without the permit the code requires triggers a penalty equal to 100% of the fee for the requisite permit if the permit is issued after the work commences (§ 20.04.070). That penalty is charged in addition to any other fee, and it reaches any person, firm, partnership or corporation initiating or engaging in the work. The city building official enforces Chapter 20.04.
