I’m replacing the fences around my house. What are the height requirements and do I need a permit?
In general, fences are limited to a maximum height of 4′, with some variations for side and rear fences. For information on fences within the County right-of-way, call the Public Works permit desk at (650) 363-1822 or 363-1821. For fences on private property, call the County Planning Division’s permit desk at (650) 363-4161. They can advise you on requirements for your area and the type of permit you will need. If you’re unsure whether the fence is on County or private property, we can provide you with that information. Call the Road Maintenance office at (650) 363-4103.
