Installing a new fence can improve privacy and property value. However, most counties require a permit if the fence exceeds 6 feet in height or is located in the front yard.
Set by local rules
Do you need a permit for Fence Installation in Los Angeles County?
In California, there is no single statewide rule for a Fence Installation; whether you need a permit is decided locally in Los Angeles County.
In unincorporated Los Angeles County, a fence under 6 feet does not need a building permit, though its placement may need Department of Regional Planning approval and fire-hazard zones require non-combustible materials; over 6 feet needs a permit. The City of Los Angeles and other cities set their own limits (commonly 6 feet rear, 42 inches front). California's Good Neighbor Fence Law governs shared costs. Because California leaves this to local jurisdictions, the reliable answer comes from Los Angeles County Department of Public Works Building and Safety. Zoning setbacks apply either way.
