Showing ordinances that apply to Castro Valley, CA
Castro Valley is an unincorporated community (population 66,441) in Alameda County, California. Because Castro Valley is not an incorporated city, it does not have its own municipal code. Instead, Alameda County ordinances apply directly to properties here. The fence requirements rules below are the ones that govern your area.
Alameda County Zoning Ordinance generally limits residential front yard fences to 3-4 feet and side or rear yard fences to 6-7 feet, with clear-vision triangles required at driveways and intersections.
Under Alameda County Zoning Ordinance Title 17, residential fences are restricted by location on the lot. Front yard fences are typically limited to 3 to 4 feet in solid construction, though taller open or lattice sections may be allowed in some zones. Side and rear yard fences may reach 6 to 7 feet. Corner lots must maintain clear-vision triangles at intersections (typically 25 feet by 25 feet) with no fence, hedge, or obstruction taller than 3 feet to preserve sight distance for vehicles and pedestrians. Fences exceeding the zone standard require a variance or design review. In unincorporated areas along scenic corridors or hillside overlays, additional design standards may apply. Agricultural zones in Livermore Valley and Sunol have different, often more permissive, fence standards for livestock and boundary purposes.
