What are the fence height limits in the City of San Diego?
Under San Diego Municipal Code §142.0310 (text current to September 2026), a solid fence on the front or street side property line is limited to 3 feet (an open fence there, 6 feet), and fences in required side and rear yards may be up to 9 feet, with anything above 6 feet open. Fences in visibility areas are limited to 3 feet. A fence under 7 feet needs no permit under the fence division; 7 feet or more needs a building permit; a fence above these limits needs a Neighborhood Development Permit.

The City’s one-page guide “When is a Permit Required?” says fences up to seven feet tall do not require a permit, but fences over six feet are prohibited in the front yard setback and fences over three feet in visibility areas (City guide, Feb 2025). Section 142.0305(a) says the fence regulations apply “whether or not a permit or other approval is required.”
A note on the 2026 code update
The code text above is the 9-2026 version. Section 142.0310 shows an amendment by Ordinance O-22109, effective July 15, 2026, and an editor’s note that those amendments “will not apply within the Coastal Overlay Zone until the California Coastal Commission certifies it.” The City says approval inside the Coastal Zone is anticipated in 2028 (City Land Development Code updates). We have not compared the old and new §142.0310 line by line, so if your home is in the Coastal Overlay Zone, ask the City which text applies to you.
What this page does not tell you
It does not cover retaining walls, pool barriers (see pool fence requirements), HOA rules, wildfire Zone 0 limits (see Zone 0 fence and gate rules), or special zones and overlays. Required yards and setbacks depend on your zone and are looked up by address. It gives no prices; see the local price guide. Before building near a neighbor, see the neighbor fence letter. This is not legal advice.
