Iron County, UT Fence Regulations: Neighbor Fence Rules (2026)

Chapter 6.04, Animals Generally, grew out of Iron County's rural fencing law rather than a residential nuisance ordinance, but it is the county's only code section addressing who pays for a boundary fence between adjoining owners. Section 6.04.010 sets the backdrop: no court can award livestock trespass damages against a landowner whose fields, subdivision or grazing land was not enclosed by a legal fence properly maintained at the time of the trespass, unless the damaged owner first offered to share the cost of a fence and the other owner refused.

Section 6.04.020 defines that legal fence precisely: not less than five horizontal wire, board, pole or similar barriers common in the neighborhood, posts no more than twenty feet apart, the lowest barrier no more than ten inches off the ground, no more than twelve inches between any two barriers, and the top barrier at least forty-eight inches high, with each post able to withstand two hundred fifty pounds of horizontal strain four feet up. Section 6.04.030 then answers the cost question directly: construction cost between adjoining landowners or users is divided equally, and so is maintenance cost afterward, unless one owner's neglect or intentional act damages or destroys the fence, in which case that owner alone pays for repairs.

The ordinance predates modern residential subdivision disputes (Ord. 44, 1970) and speaks in terms of farms and grazing land, but its equal-cost-sharing rule is the operative county text for any adjoining-owner fence dispute in the unincorporated area.
