Vacaville, CA Building Safety: Building Inspections (2026)

1 to add Vacaville-specific inspection procedure. It states that the final inspection of a building permit acts as the certificate of occupancy for new single-family dwellings, but only once every required inspection is documented as passed, including the final inspection, with signatures or initials from the Building Official or a deputy entered on the official building inspection card. Certificates of occupancy generally will not issue without sign-off from all applicable agencies, the city fire department, and other relevant city departments, and occupying a structure without that approval is itself declared a code violation and a safety hazard or public nuisance.

Commercial buildings are treated differently: subsection A exempts commercial development from needing a new certificate of occupancy where there is no change in tenant, use, occupancy classification, originally permitted tenant space square footage, occupant load, or construction type. 6 to delete an exception that previously excused certain lath, gypsum board, and gypsum panel product installations from inspection, meaning Vacaville requires that inspection in situations the base state code would have exempted. 090 further requires the certificate of occupancy itself to be posted conspicuously on the premises once issued, except for Group R-3 occupancies and their accessory structures.
