Bannock County, ID Fence Regulations: Height Limits (2026)

Article VI of Chapter 17.52, governing fences in Bannock County's nonagricultural zoning districts, ties fence height directly to setback lines. Section 17.52.280(B) bars any solid fence taller than three feet from standing within the required front setback of a lot, so a taller privacy fence has to sit behind the setback line, not out toward the street. Corner lots carry an added restriction under subsection C: measured from the intersection of the legal right-of-way lines, in each direction for a distance equal to the required setback, no solid fence or walled enclosure over three feet tall may be built, and no structure, hedge, shrub, tree or other growth over three feet may stand within that triangular area either, so landscaping is regulated the same as a fence for sight-distance purposes.

Where a corner lot's rear line abuts the side property line of a lot whose house faces the side road, the stricter side-yard building setback controls, and any solid fence there taller than four feet has to respect it. Bannock County adopted diagrams in Section 17.52.300 illustrating exactly how these triangles are measured on back-to-back corner lots and on corner lots bordering a home that faces the side street, doubling the local-road thirty-foot dimension to fifty feet where an arterial or collector road is involved.

Property owners who need a taller fence closer to the street than these standards allow can ask the planning and development council for an exception under Section 17.52.290, but the council will only approve it on a showing that the fence will not create a traffic problem for the public or a neighboring owner and will not be incompatible with the neighborhood.
