Local Guidelines
Fence Rules & Permits in Diamond Bar, CA

A few things to consider before you install a fence in Diamond Bar. These are general guidelines — always confirm current requirements with the City before you start.

📏
Front Yard Height
Along the front of the property and on the street-facing side of a corner lot, fences, walls, and hedges are limited to 42 inches. Chain link is not permitted on residential property within a required yard adjacent to a street, and masonry walls visible from the street must use decorative materials.
🧱
Side & Rear Yard Height
In the rear yard and interior side yards, fences and walls may go up to 6 feet — the standard privacy height for a backyard enclosure. If the fence sits on a shared property line, the City asks for the adjoining owner's signature on its Fence, Wall and Hedge form.
📋
When You Need a Permit
A standard fence or freestanding wall does not require a building permit, but it does require Planning Division approval through an over-the-counter Zoning Clearance submitted with a site plan. Retaining walls require Planning approval plus a building permit, and taller walls may also need Public Works sign-off.
🚦
Corner Lots & Sight Lines
Near the intersection of streets, alleys, and driveways, a traffic safety sight area keeps drivers' views clear. A solid fence or wall is limited to 30 inches inside that area, though a fence that is at least 75% open — wrought iron or grillwork — may be built to the height otherwise allowed.
Good to Know
If your home is part of an HOA, check your community's CC&Rs before installing — many HOAs add their own material and height rules on top of the City's. Building a pool or spa? California's Pool Safety Act (Health & Safety Code §115922–115923) requires at least two independent, approved drowning-prevention features, such as a 60-inch enclosure. Fence codes can change, so we always recommend confirming current requirements with the Diamond Bar Community Development Department before you start. Have questions about your property? Contact Legacy Fence and we'll help you sort it out.

The Legacy Fence team were responsive, patient, professional, and accommodating. I had them install a boundary fence with my neighbor, and there were specific demands from both homeowners — they were flexible in making sure every concern was met. Definitely recommend Jose and his team!
