Yolo County, CA Swimming Pools & Spas: Pool Permits (2026)

Sec. 7-1.02(b) of the Yolo County Code adopts "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." 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. 7-1.03). Permit fees are charged "in accordance with the current fee schedule as adopted by the Board of Supervisors" (Section 109.2, added by Sec.

7-1.04(a)(5)), based on the Building Official's valuation of the pool project. A pool permit is void if work is not commenced within 12 months, or is suspended or abandoned for 180 days, under Section 105.5 (Sec. 7-1.04(a)(4)); reactivating an expired permit costs half the original fee. If pool construction starts before a permit is pulled, Section 109.4.1 (Sec. 7-1.04(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.

8-2.1011, 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. A denied or disputed Building Official determination can be appealed to the Planning Commission within 30 days under Section 113.4 (Sec. 7-1.04(a)(10)).
