Summary
The City of Napa requires a building permit for any swimming structure deeper than 24 inches: including in-ground, above-ground, and portable pools, hot tubs, and spas. Because of landslide, fault, and flood hazards, in-ground pools also require a geotechnical (soils) report or a signed Soils Report Waiver. Plan review takes about 21 business days.
When a building permit is issued for the construction of a new swimming pool or spa or the remodeling of an existing swimming pool or spa at a private single-family home, the respective swimming pool or spa shall be equipped with at least two of the following seven drowning prevention safety features ... Before the issuance of a final approval for the completion of permitted construction or remodeling work, the local building code official shall inspect the drowning safety prevention features required by this section and, if no violations are found, shall give final approval.
Full Breakdown
Pool permits in Napa are issued by the Community Development Department under Title 15 of the Municipal Code, which adopts the California Building Code, California Residential Code, and California Plumbing/Electrical/Mechanical codes. A permit is required for any swimming structure containing water deeper than 24 inches, including in-ground pools, above-ground pools, portable pools, hot tubs, and spas. For in-ground pools, the city requires a geotechnical report addressing Napa's landslide, earthquake fault, and flood-zone exposure; alternatively, the applicant may submit a Soils Report Waiver Request signed by a licensed design professional. Initial plan review takes 21 business days; the city does not accept incomplete submittals. Plans must show site setbacks, the chosen H&S 115922 safety features, the proposed enclosure or cover, pool electrical and bonding details, and floodplain status if the property is in the FP Overlay.
Violations & Fines
Installing a pool deeper than 24 inches without a city building permit is a Title 15 violation. The Building Division can issue stop-work orders, require after-the-fact permitting at higher fees, or order pool drain-down until inspection. Front-yard or setback violations may require relocation; floodplain violations can trigger NFIP-level enforcement.
