Deck Construction Permits in Vallejo

Local Rule

City of Vallejo Building Division

The city's own Permit Related Questions FAQ confirms the standard statewide exemption item for decks not exceeding 200 square feet, following the same numbered CBC 105.2 list used across the Bay Area. Vallejo's own Deck Construction Guide adds a genuinely distinctive local rule: a licensed design professional's stamp is required once a deck's standing surface reaches 12 feet or more above the ground at any point, or whenever the deck will support a large concentrated load such as a hot tub, well beyond the point where most cities simply require engineered plans. Footings must sit at least 12 inches below undisturbed ground, sized for a default soil bearing capacity of 1,500 pounds per square foot unless a soil report says otherwise.

How This Compares to Solano County

Vallejo'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.
