Mission Viejo, CA Fence Regulations: Height Limits (2026)

Mission Viejo Municipal Code Sec. 015(f) sets the citywide standard for fences, walls, and hedges. On a corner parcel, no fence, wall, hedge, sign, mound of earth, or other visual obstruction may exceed 42 inches above the nearest street curb elevation within the traffic safety sight area; the code carves out narrow exceptions for public utility poles, trees trimmed clear at least six feet above the intersection grade, open-growth saplings not planted as a hedge, and official warning signs. Everywhere else on a parcel, a fence, wall, or hedge may rise to a maximum of six feet, except that within a required front setback or street-side setback the limit drops back to 42 inches, or whatever lower figure other code sections require.

A separate provision in Sec. 015(k)(3) caps perimeter fences and walls at six feet generally, measured from the finished grade of the parcel at the fence or wall, while architectural walls that are integral to and attached to the structure may exceed six feet with director approval. Only one fence or wall design is permitted per parcel or development, and any addition must match the original design and materials, subject to sign-off by the director of community development. Property owners planning a fence near a street corner or a front yard should confirm the exact sight-triangle dimensions and setback lines with the community development department before building, since exceeding either the 42-inch or six-foot cap without approval creates a code enforcement issue.
