Salt Lake County, UT Fence Regulations: Height Limits (2026)

The forty-two inch cap in subsection B is tied to a mapped line on each site: the designated limits of disturbance. Outside that line, a fence may not exceed forty-two inches in height unless the county itself requires taller fencing, and the ordinance gives fenced corrals for horses or other animals as its example of county-required fencing. Two locations carry the cap regardless of where the disturbance boundary falls. Subsection C holds fences in front yards and along roadways to forty-two inches. Subsection D addresses identified wildlife corridors, where fences are strongly discouraged in the first place and in no case may exceed forty-two inches, wording that leaves no room above that height in a corridor.

Height is not the only constraint. All FCOZ fences are subject to the intersecting streets and clear visibility restrictions of the county's zoning title, must conform to the design standards of the section under subsection E, and under the companion site plan standard must appear on an approved site plan before going up. The height rules entered the code through Ordinance 1808, adopted March 14, 2017, and apply within the mapped overlay zone in the county's unincorporated foothill and canyon areas.
