Idaho Falls, ID Fence Regulations: Material Restrictions (2026)

A search of the City of Idaho Falls Comprehensive Zoning ordinance (Title 11) found no general prohibition on particular fence materials, no ban on barbed wire, razor wire, or electric fences in residential zones, and no list of approved versus banned fence materials for ordinary properties. Where material does matter, it is tied to visibility and screening rather than aesthetics or safety bans. Section 11-4-8(C) provides that, for the front-yard sight rule, 'a chain-link fence without slats shall not be considered sight obscuring,' meaning chain-link without slats may be treated differently than a solid fence in the 15-foot front-yard area. Conversely, the landscaping and buffering tables require an 'opaque fence' for screening between certain uses and zones and expressly state that 'opaque fence... shall not include chain link fencing with or without slats' (see Section 11-4 screening/buffer requirements). Refuse and recycling areas and open storage must be screened by solid fences or walls at least six feet (6') high. Because the residential code is silent on material bans, materials like wood, vinyl, composite, masonry, and chain-link are generally allowed, but confirm any unusual material (such as barbed or electric fencing) with the Building Division before installing.
