Swimming pool permit rules in Solano County, CA — also covering above-ground pools, in-ground pools, and spa installations — set fencing, barrier, alarm, and inspection requirements.
In unincorporated Solano County, a building permit is required to build an in-ground pool, in-ground spa, or most above-ground pools. Permits are issued by the Department of Resource Management, Building & Safety Services Division, which enforces the 2022 California Residential and Building Codes through County Code Chapter 6.3.
Solano County's Department of Resource Management, Building & Safety Services Division, reviews and issues building permits for residential swimming pools and spas in the unincorporated county. The division enforces the California Building Standards Code (Title 24) - including the 2022 California Residential Code, California Building Code, and California Electrical Code - as adopted locally through County Code Chapter 6.3 (Building Standards and Codes). Under California Building Code Section 105.2, a permit is not required only for a prefabricated above-ground pool accessory to a single-family (Group R-3) home that is less than 24 inches deep, holds no more than 5,000 gallons, and sits entirely above ground; anything larger needs a building permit. Applications, plan-check fees, and final permit fees are handled through the county's online permitting portal. A separate electrical permit is required for the pump, lights, and equipotential bonding under California Electrical Code Article 680. The county publishes a 'New Swimming Pools/Spas' submittal checklist. Contact Building & Safety at 707-784-6765 or building@solanocounty.gov.
Building without a required permit triggers a stop-work order and corrective-permit fees under the adopted California Building Code (Section 109/110 as adopted by County Code Ch. 6.3). Work cannot pass final inspection or be legally used until the pool barrier and equipment are inspected and approved. Unpermitted construction can be pursued as a code-compliance case by Resource Management, and the suction-outlet and barrier safety requirements of the California Health & Safety Code (Pool Safety Act) must be satisfied before sign-off.
