Summary
In unincorporated Iron County, Section 17.36.070 caps fences, walls and hedges at six feet in every zoning district, and Section 17.36.120 separately bars any obstruction over two feet tall inside the sight-triangle formed at street intersections, measured forty feet back from the corner along each street line.
Fences, walls and hedges shall not exceed six feet in height. ... In all zoning districts, no obstruction to view in excess of two feet in height shall be placed on any corner lot within a triangular area formed by the street property lines and a line connecting them at points forty feet from the intersection of the street lines except a reasonable number of trees pruned to permit unobstructed vision to automobile drivers and pumps at gasoline service stations.
Full Breakdown
Section 17.36.070 is a single flat sentence that applies countywide in unincorporated Iron County: fences, walls and hedges shall not exceed six feet in height, without a lower limit for front yards, meaning the six-foot cap applies the same whether the fence sits along a front, side or rear property line. The Table of Site Development Standards at Section 17.16.040 separately requires a solid, non-landscape fence or wall at least six feet tall to screen accessory outside storage where it is adjacent to an agricultural or residential district, so the six-foot figure also functions as a minimum screening height in that specific situation.
Corner lots carry an additional, independent limit under Section 17.36.120: in all zoning districts, no obstruction taller than two feet may sit within the triangular area formed by the street property lines and a line connecting points forty feet from the intersection along each line, except a reasonable number of pruned trees and gas station pumps. Section 17.36.020(G) also allows underground structures like swimming pools or storage tanks in a required yard as long as they sit at least fifteen feet from any property line, and lets walls and fences that otherwise comply project into required yards.
Violations & Fines
A fence, wall or hedge over six feet, or any obstruction over two feet inside the forty-foot corner sight-triangle, is a zoning violation under Section 17.72.070, a Class B misdemeanor punishable by up to a $1,000 fine and six months in jail, with each day the excess fence remains a separate offense; the county may also issue a lower administrative citation and fine under Section 17.72.100 instead of pursuing criminal charges.
