Monterey Park, CA Fence Regulations: Height Limits (2026)

Section 21.10.120 splits commercial fencing into required screening walls under Subsection (A) and voluntary, or elective, walls under Subsection (B); the height limits in this record govern the elective category, meaning anything an owner installs beyond what the code already mandates. Subsection (A) separately forces a three-foot masonry wall or sight-obscuring hedge, set in a three-foot landscaped strip, wherever front-yard parking faces a commercial street, and a six-foot masonry wall wherever a commercial lot shares a side or rear line with an R-zoned residential lot; concrete block walls in either case must be painted to match or complement the building.

For anything built beyond those required walls, Subsection (B)(1) sets the elective limits: six feet in a front yard, dropping to three feet in the C-B Zone, and up to 10 feet on any required rear or side yard. Once a wall or fence rises above six feet, the City Planner must approve the design, and the portion above six feet cannot obstruct more than 10% of visibility looking through it, a see-through requirement aimed at sight lines rather than solid screening. Subsection (B)(2) also lets a retaining wall within three feet of a property line be topped with a fence, wall or hedge of whatever height would otherwise be allowed at that location as if the retaining wall were not there, illustrated in the code's Figure 21.10(C).
