Kane County, IL Fence Regulations: Material Restrictions (2026)

Section 25-7-5-3 of the Kane County Zoning Ordinance, part of Article VII on zoning districts, sets two rules for fences on unincorporated land. First, within 100 feet of the centerline of any intersecting road, street or at-grade railroad crossing, no fence or hedge that cannot be seen through or over from a three-foot height above the roadway may be built, planted or allowed to grow closer to the centerline than the setback distances fixed in section 25-7-5-2, protecting driver sight lines at corners. Second, no fence carrying barbed wire, spikes or any similar device, and no electrically charged fence capable of delivering a shock, may be erected, placed or maintained on or within any lot used for residential purposes.

The prohibition traces to Ordinance 78-79 (June 13, 1978) and was carried forward through amendments in 1982, 1988, 1993 and 2002 (Ord. 02-81). Because the ban is keyed to residential use, it does not reach farmland: section 25-5-4-4 exempts buildings, structures and land used principally for agriculture from the zoning ordinance's requirements other than setbacks, so barbed wire and electric containment fencing remain lawful for livestock operations outside residential lots. The rule sits inside Chapter 25, the county's zoning code, which under Illinois law (55 ILCS 5/5-12001) governs only the unincorporated county; it has no effect inside Aurora, Elgin, Geneva, St.

Charles, Batavia, Carpentersville or South Elgin, each of which zones under its own municipal code. A homeowner planning a fence on an unincorporated lot must choose chain link, wood, vinyl or non-electrified wire mesh rather than barbed wire or an electric charger, regardless of the fence's height or setback compliance.
