Deck Construction Permits in Vacaville

Local Rule

City of Vacaville Community Development Department

The citys own permit FAQ confirms the standard California exemption without modification: a deck not attached to the dwelling, not exceeding 200 square feet, and not exceeding 30 inches above the adjacent ground surface does not need a building permit. Applicants are directed to confirm lot coverage, setback, location and height requirements with the Planning Division before starting any deck, shed or fence work, since the building exemption does not clear a project of separate zoning review. All residential and commercial improvements outside that list otherwise require a permit, though the Building Official can grant a case-by-case exemption for minor commercial repairs.

How This Compares to Solano County

Vacaville's own rule is shown above (Depends on project scope). Here is the separate rule that applies at the county level, for context:

Solano County Resource Management, Building & Safety

Unusually, the County requires a building permit for all decks, decks are absent from the general permit-exempt list and the Patios & Decks page states that all decks require a permit; a patio or deck cover of any size also needs one. A distinctive material rule applies: a deck built within 18 inches of the ground must use redwood or pressure-treated lumber to prevent dry rot. The site plan must locate wells, septic systems, LP tanks and streams.
