Do I need a permit to replace an existing 6-foot wood fence?
No. Replacement of a wood fence at the same 6-foot height is within the Ordinance 72-6.202 exemption (fences not over 7 feet high). However, if the fence serves as a swimming pool barrier, it must be replaced promptly because pool barrier requirements remain in force.

Anything over 7 feet requires a building permit from the Contra Costa County Building Inspection Division. Apply at the Application and Permit Center at 30 Muir Road, Martinez, or call (925) 655-2700.
