Fence Installation Permits in California
In California, fences are governed by local zoning (commonly 6 ft in back and side yards, lower in front). State law covers shared boundary fences (the 'good neighbor' cost-sharing rule) and treats fences over 10 ft as possible 'spite fences.' A fence used as a pool barrier always needs a permit.
The Building Code in California
California Residential Code (2022 CRC) + Title 24
California builds on the California Building Standards Code (Title 24), adopted by the California Building Standards Commission and enforced locally. Fences over 6 feet generally require a permit; in mapped fire-hazard zones, additional non-combustible requirements apply to fence sections attached to the home.
Who Sets the Rules
What's Different in California
California generally requires a permit for fences over 6 feet (about 3.5 ft in front yards). It has a "Good Neighbor Fence Law" (Civil Code 841) presuming shared cost between adjoining owners. Pool barriers must be at least 60 inches. In CAL FIRE zones, the fence where it meets the house must be non-combustible.
