Martinez FAQ
Is barbed wire allowed on a residential fence in unincorporated Contra Costa County?
There is no county-wide ordinance prohibiting barbed wire in unincorporated residential areas, but specific zoning districts and HOA rules may restrict it. Some cities in the county (e.g., Pittsburg) ban it outright in their residential zones; the county itself does not.
Do I need a permit for a stucco or brick wall instead of a wood fence?
Yes. Ordinance 72-6.202 expressly states concrete and masonry walls are not 'fences' and require a building permit, even if they are under 7 feet tall.
Richmond FAQ
Can I install an electric fence to keep my dog in?
Underground invisible dog fences (shock collars) are generally permitted. Above-ground electrified fences are prohibited in residential zones.
Is chain link allowed in my front yard?
In most Richmond residential zones yes, though vinyl-coated versions are preferred. Check with Planning if you're in a design review district.
