DuPage County, IL Sign Regulations: Political Signs (2026)

Section 37-1104(E), "Temporary Political Signs," is one of the exempt-and-temporary-sign categories that require no sign permit as long as the sign stays within the stated limits, per the lead-in language of Section 37-1104. Political signs may be placed in any zoning district in unincorporated DuPage County, residential, business or industrial, without the district-specific restrictions that apply to permanent signage. The timing window is fixed at both ends: a sign cannot go up more than 60 days before an upcoming election, and it must come down within 7 days after the election.

The size limit is per zoning lot rather than per sign, so a property owner can post several small signs as long as their combined copy area does not exceed 10 square feet, and no individual political sign can exceed 4 feet in height above grade. Because these are exempt signs, they fall outside the general permit requirement in Section 37-1103(A)(17), but they still have to comply with the countywide siting rules in Section 37-1103(A): a political sign cannot be attached to a utility pole, telephone pole or tree, and it cannot be erected within a public right-of-way except as the highway authority responsible for that right-of-way allows.

A political sign that exceeds the 60-day/7-day window, the 10-square-foot total, or the 4-foot height limit loses its exempt status and would need to meet the permanent-sign standards of the district instead.
