Concord FAQ
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.
What about a fence taller than 7 feet?
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.
Oakley FAQ
Do I need a permit to replace an existing fence?
Generally no if you replace in-kind at the same height and location, unless the fence exceeds 6 feet. Repairs under 50% of the fence value typically do not trigger permits.
Can I build my own fence without a licensed contractor?
Yes, on your owner-occupied property. Contractor-built fences require a C-13 or appropriate California contractor's license.
Are pool fence inspections required even for existing pools?
At time of pool installation or sale, yes. Property transfers trigger pool safety disclosure and may require upgrades to current standards.
