In California, fence permit requirements are set at the county or municipal level. The general threshold across most California jurisdictions is: Most CA cities: over 6 ft requires permit; coastal/flood zones add requirements. However, local rules vary — always verify with your specific county or city building department before beginning construction.

How to Find Your California County's Rules
Search for "[your county name] California fence permit" to find your county building department's website. Look for the building, planning, or development services department. Most county websites publish their permit fee schedules and threshold rules online. If you can't find it, call your county's building department directly and ask: "Does a [height]-foot fence in my backyard require a permit?"
Setback Rules in California
Setback requirements for fences in California vary by county zoning district. Most residential zones allow fences to be placed at or near rear and side property lines. Front yard fences must stay behind the right-of-way boundary (which is not the same as the curb or sidewalk edge). See our setback rules guide for how to measure correctly.
