DuPage County, IL Fence Regulations: Fence Permit Requirements (2026)

DuPage County Zoning Ordinance Sec. 1(C) states plainly that all fences and walls shall require the issuance of a permit prior to their erection or construction. The permit duty sits inside the General Requirements subsection that opens the county's fence, wall and shrubbery article (Sec. 5 even come into play. Applicants file with the DuPage County Department of Economic Development and Planning, Zoning Division, the same office that reviews special events, home occupations and other zoning matters under this chapter. Because the permit requirement is untethered from height or material, it captures everything from a four-foot open front-yard fence to an eight-foot-six-inch industrial security fence with barbed wire under Sec.

1(G). The permitting step also lets the county confirm compliance with the vision clearance triangle rule in Sec. 3, which bars any obstruction over three feet within twenty-five feet of a street or service-drive intersection, and with the stormwater rule in Sec. 1(B), which bars a fence, wall or shrubbery that would impede the natural flow of stormwater across the lot. Skipping the permit and building anyway exposes the fence to a removal or correction order once inspectors observe it, since an unpermitted fence is treated the same as any other unpermitted zoning structure under the county's general enforcement provisions.
