Mission Viejo Municipal Code Section 9.20.015 (General Standards) sets the citywide fence and wall height rules. A fence, wall, or hedge up to six feet may be located anywhere on a parcel except in a traffic safety sight area, a required front setback, or a street-side setback - where the maximum is 42 inches. When ground levels differ between adjoining parcels, the height of a property-line fence is measured from the finished grade of the highest contiguous parcel. Both sides of perimeter walls or fences must be architecturally treated. California Civil Code Section 841 governs cost-sharing of shared boundary fences with adjoining owners.

Mission Viejo FAQ
How tall can I build a fence in my Mission Viejo back yard?
Up to six feet. Mission Viejo Municipal Code Section 9.20.015 allows fences, walls, and hedges up to six feet anywhere on a parcel except in a required front setback, a street-side setback on a corner lot, or a traffic safety sight area, where the maximum drops to 42 inches. If your neighborhood is governed by an HOA, the CC&Rs may impose stricter material, color, or view-related standards on top of the city rule.
What is the front yard fence height limit in Mission Viejo?
42 inches. Within a required front setback, a street-side setback on a corner lot, or any traffic safety sight area, fences, walls, and hedges are capped at 42 inches by Section 9.20.015. This protects driver visibility at intersections and driveway approaches. Fences over 42 inches in those areas are a code violation, and the city can require their removal or reduction.
