Summary

Yolo County has no separate swimming-pool permit process: a residential pool falls under the 2019 California Residential Code, which the county adopted by reference including Appendix V, the Swimming Pool Safety Act, under Sec. 7-1.02(b). The Chief Building Official issues the permit, and construction must also meet the zoning setback and lot-coverage standards for pools in Sec. 8-2.1011.

These county ordinances apply to unincorporated areas of Yolo County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

The 2019 California Residential Code including Appendix Chapters: H–Patio Covers, Q-Tiny Houses, S-Strawbale Construction, V-Swimming Pool Safety Act, and X-Emergency Housing, as published in Title 24, Part 2.5 of the California Code of Regulations and amended in Section 7-1.05.

Full Breakdown

Sec. " Because Appendix V is adopted, a residential swimming pool is built and permitted the same way as any other structure regulated by the CRC: through a permit issued by the Chief Building Official under the administrative provisions carried over from the California Building Code, Chapter 1, Division I and II (Sec. 03). 2, added by Sec. 04(a)(5)), based on the Building Official's valuation of the pool project. 5 (Sec. 04(a)(4)); reactivating an expired permit costs half the original fee. 1 (Sec. 04(a)(6)) requires an investigation fee equal to the permit fee before the county will issue one.

Beyond the building permit, Yolo's zoning code layers on siting rules for pools in any zone: under Sec. 1011, a private pool must sit on the rear half of the lot or at least 50 feet from the front property line, and pool use for paid instruction or parties requires a Use Permit. 4 (Sec. 04(a)(10)).

Violations & Fines

Building, occupying, or operating a pool without the required permit is a misdemeanor under Yolo County Code Sec. 1-2.01, punishable by a fine of up to $500, up to six months in county jail, or both, with each day of noncompliance a separate offense. Unpermitted pool construction also triggers the Sec. 109.4.1 investigation fee, equal to the full permit fee, before the county will issue a permit retroactively.

Frequently Asked Questions

Do I need a permit to build a swimming pool in unincorporated Yolo County?
Yes. Yolo County adopted the 2019 California Residential Code, including Appendix V, the Swimming Pool Safety Act, under Sec. 7-1.02(b), so a residential pool is permitted the same way as any other structure: through the Chief Building Official, with fees set by the Board of Supervisors' current fee schedule.
Where can a private pool be located on my lot?
Sec. 8-2.1011 requires a private pool to sit on the rear half of the lot or at least 50 feet from the front property line, no closer than 5 feet to any lot line, and covering no more than 40 percent of the required rear yard.
What happens if I build a pool before getting a permit?
Section 109.4.1, added to the building code by Sec. 7-1.04(a)(6), requires the county to charge an investigation fee equal to the full permit fee before issuing one, on top of any misdemeanor penalty under Sec. 1-2.01.
Can I run a pool for lessons or parties for a fee?
No, not without a Use Permit. Sec. 8-2.1011(a) limits a private pool to the enjoyment of the occupants of the premises and their guests, and it requires a Use Permit before the pool can be used for paid instruction or parties held for a fee.
