Signs visible to Chicago's federal-aid expressways trigger Illinois Highway Advertising Control Act review by IDOT plus a Chicago sign permit. Off-premise advertising is restricted to zoned commercial and industrial areas with strict spacing, height, and lighting rules.
Under 225 ILCS 440, IDOT regulates outdoor advertising visible from primary and interstate highways including I-90, I-94, I-290, I-55, and I-57 within Chicago. Off-premise signs must be in C or M zoning, spaced 500 feet apart on interstates, capped at 1,200 square feet face area, and not exceeding 100 feet in total height. Local Chicago Sign Ordinance MCC 17-12 and Building Code 13-20 add further setback and structural rules. The Aviation Department reviews any sign within five miles of O'Hare or Midway. Lakefront Protection District blocks freeway-facing signs along South Lake Shore Drive. Permits require state and city co-approval; renewals are tightly tracked.
Erecting an expressway-visible sign without IDOT registration plus a Chicago sign permit triggers IDOT removal orders, a $500 per day Chicago code fine, and potential criminal penalties for unpermitted billboards.
