Summary
In unincorporated Santa Clara County, a building permit from the Department of Planning and Development is required to construct a residential pool or spa. The County Code includes a dedicated swimming pool division (Division B18), and pools are also regulated as accessory uses under the Zoning Ordinance.
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
Residential swimming pools and spas in unincorporated Santa Clara County are built under permits issued by the County's Department of Planning and Development (Building Division). The County Ordinance Code contains a dedicated Division B18, Swimming Pools, within the Building Regulations title, and the County enforces the California Building Code (CBC) and California Residential Code that govern pool construction statewide. Because a pool is a structure and an accessory use, it must also satisfy the Zoning Ordinance. 20 (Supplemental Development Standards), subsection J, requires swimming pools and spa pools to be located at least five feet from any property line or right-of-way, measured to the interior wall of the pool; pool filters, pumps, and other appurtenant machinery must also sit at least five feet from any property line or right-of-way.
State law (Health and Safety Code Section 115922, the Swimming Pool Safety Act) attaches drowning-prevention requirements at the time a building permit is issued for a new or remodeled pool or spa at a single-family home, and the local building official inspects those features before final approval. Public pools and spas are separately permitted and inspected by the County Department of Environmental Health. Applicants should confirm current building-permit fees and submittal requirements with Planning and Development before applying.
Violations & Fines
Building a pool or spa without the required building permit or inspections can result in stop-work orders, code-enforcement action, and required corrections (including added safety features) before the work can be finalized.
