Chino Hills, CA Fence Regulations: Material Restrictions (2026)

120(A) treats fence and wall material as its own standard, separate from the height limits in the same section. Walls and fences generally have to be durable material: masonry, masonry combination, stone, brick, concrete, or wrought iron and tubular steel, plus any other material the Planning Commission or the Community Development Director approves for durability, aesthetics, and sound attenuation. Wood fencing is allowed on developed single-family properties if it complements the architectural style of the home, and the code requires it to be kept maintained at all times, not left to weather and fail.

Two materials are restricted outright rather than merely reviewed. Chain-link or similar wire fencing cannot go in a front yard or a street-facing side or rear yard, though chain-link installed before November 24, 2015, the effective date of Ordinance No. 293, is treated as a legal nonconforming structure that can stay. Barbed wire and razor ribbon are banned as wall or fence material citywide, with only two carve-outs: undeveloped Agriculture Ranch or Open Space areas where it is needed to restrict cattle movement, and utilities or other public facilities that require it for security.

The same subsection separately requires walls and fences visible from a street or a development's common areas to be decorative and to complement the architectural style of the surrounding development, layering a design-review expectation on top of the bare material rules.
