Tuolumne County, CA Fence Regulations: Height Limits (2026)

Unlike many California jurisdictions, Tuolumne County's Title 17 Zoning Ordinance does not establish a specific maximum fence height for residential parcels. Chapter 17.22.030.C lists walls and fences among the structures that may be erected or projected into any required yard, meaning a fence can be placed within the front, side, or rear setback areas. Because the zoning code is silent on height, the operative limit comes from the adopted 2022 California Building Code. Under CBC Section 105.2, a building permit is not required for 'Fences not over 7 feet (2134 mm) high.' Fences taller than 7 feet therefore require a building permit and engineering review. Note that masonry or block walls and combinations of fence-on-wall can trigger the permit threshold sooner, and fences near driveways or intersections must not block vehicular sight lines. Within the front setback, only a screening role is contemplated; the standards used for commercial/multifamily screening (refuse and loading areas) call for a six-foot wall, fence, or evergreen. Always confirm placement against the 35-foot setback from street centerline in Chapter 17.22.030.B.1.
