Permits

Plumbing permits in Napa County: who issues them.

Plumbing permit fees, forms and process

Whether a job needs a plumbing permit is the call of the building department of the city or county with jurisdiction, and a city or county that requires one has each applicant give their CSLB license number or say why they are exempt. One exemption is the owner-builder: an owner improving their own property who does all the work personally, or through their own employees paid wages only, with none of it intended or offered for sale (B&P Code § 7044).

Permit guides here are written per city, because that is who issues them.
