Deck Construction Permits in Concord

Local Rule

City of Concord Building Division

Concord sits in Contra Costa County, whose own published exempt-work bulletin (adopted region-wide under the 2022 CRC) confirms the standard deck exemption item unchanged: 200 square feet, 30 inches above grade, not attached to a dwelling, no required exit door. The city's own Planning Division FAQ adds a real local detail for a related structure: a fence up to 3 feet is allowed within the first 20 feet of the front property line, and fences in side or rear setbacks can be increased up to 8 feet only with an approved Minor Exception Permit from Planning. In the standard R-1 zone, typical setbacks run 20 feet front, 5 feet side and 20 feet rear.

How This Compares to Contra Costa County

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

Contra Costa County DCD, Building Inspection Division

Per County Ordinance 72-6.202, a deck is exempt only if it is 200 sq ft or less, no more than 30 inches above grade, not attached to a dwelling and does not serve the required exit door. Beyond that, a larger or elevated deck can trigger a Drainage Plan when it adds 1,000 sq ft or more of impervious surface (Ord. 2007-01) or a geotechnical report when construction of 500 sq ft or more sits on a slope over 10 percent, and CalGreen C&D debris rules apply to most new work.
