Mission Viejo, CA Fence Regulations: Material Restrictions (2026)

Mission Viejo Municipal Code Sec. 015(f) governs the materials allowed in any fence, wall, or hedge built in the city. Subsection (8) prohibits the use of electrified fence or razor wire fence in conjunction with any fence, wall, or hedge, or by itself, within any zone, unless required by a law or regulation of the city, state, or another agency. Subsection (9) prohibits barbed wire outright unless the director of community development approves it. Subsection (10) confines chain link fencing to use with private or commercial tennis courts, or where another law or regulation requires it, meaning a standard residential yard cannot be fenced in chain link under this code.

Beyond material bans, Sec. 015(f)(7) requires that any wood or uncolored cinder block fence or wall visible from a public right-of-way receive a decorative finish compatible with its surroundings: wood must be painted or stained, and uncolored cinder block must be covered with stucco or a similar material. Crib block walls paired with landscaping and a maintenance program may be allowed only with planning commission review under subsection (6). These material rules apply on top of the height standards in the same section, so even an approved material must still meet the applicable 42-inch or six-foot height cap.
