Simi Valley, CA Fence Regulations: Height Limits (2026)

Under SVMC Section 9-30.050 (Height and Location Requirements for Fences, Walls, and Hedges), property line fences and walls outside of the front setback may not exceed six feet in height as measured from the highest adjacent grade. In the front yard, fences are limited to approximately 42 inches so as not to obstruct visibility, and within any Traffic Safety Sight Area (TSSA) or the public right-of-way, no fence, wall, or hedge over 24 inches high measured from the top of the nearest street curb (street level, if no curb) is allowed without a permit. If a yard is adjacent to a major arterial street and/or a commercial or industrial zone, the property line wall or fence may be allowed to be up to eight feet in height. Garden walls over six feet and any retaining wall may also require a Building Permit in addition to a Zoning Clearance. The City directs residents to review the Residential Fences and Walls Exhibit and SVMC Section 9-30.050 before installing or replacing a fence or wall, and to prepare a plot plan showing the location, type, and height for Planning Division review.
