San Jose FAQ
Does a hot tub need a fence in Santa Clara County?
Not if it has a listed safety cover meeting ASTM F1346, which exempts a spa or hot tub from the Pool Safety Act barrier requirements. Without a compliant cover, the spa must meet the same two-of-seven safety-feature rule that applies to pools (HSC 115922).
Do I need a permit for a spa?
Yes. A spa or hot tub is treated like a pool under Zoning Ordinance Section 4.20.J, needs a five-foot setback, and generally requires a County building and electrical permit from the Department of Planning and Development.
Sunnyvale FAQ
