Evanston FAQ
Can a Cook County municipality approve a billboard IDOT denied?
No. State law preempts local approval of off-premises freeway-facing signs that fail HACA standards. Local governments may impose stricter limits but cannot override IDOT permit denials based on size, spacing, or zoning grounds.
Are on-premises business signs covered by HACA?
No. Signs that advertise the activities or products of the business on the same property where the sign sits are exempt from HACA permitting. They remain subject to Cook County or municipal sign code zoning regulations including height and area.
How do I apply for an IDOT outdoor advertising permit?
Submit IDOT Form OUT 102 with site plan, lease or ownership proof, zoning verification, and the permit fee to the IDOT Bureau of Operations. Annual renewals are required, and signs must be tagged with the issued state permit number.
