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

The Town of Apple Valley is an incorporated municipality in San Bernardino County, so its own Title 9 Development Code, not San Bernardino County zoning, governs fences here. The Town's published guidance limits front-yard fences to approximately 3 1/2 feet in height, while fences in rear and interior side yards may reach up to roughly 8 feet. On corner lots, fences and walls within the intersection sight triangle must stay low enough to preserve traffic visibility. A Building Permit is required for any wall or fence exceeding 6 feet, and the Town separately notes that fences taller than 7 feet trigger permit review. A specific Wall/Fence Height Permit applies under Development Code Section 9.37.070(B): with Planning Division approval, a wall or fence may rise above 6 feet up to a maximum of 8 feet where it separates a commercial or industrial use from an existing residential use or residentially zoned property, measured from the lowest grade adjacent to either side of the wall. Equestrian (R-EQ) and large-lot rural parcels follow the same height framework but also coordinate with animal-keeping setback buffers. Heights are measured from adjacent grade. Because exact figures and exceptions vary by zone and by recorded-map conditions, confirm with the Community Development Department before building.
