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.
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.
