Cook County does not use Los Angeles-style Historic Preservation Overlay Zones. Instead, Cook County Historic Preservation Ordinance Chapter 102 Article VI establishes Historic Districts and Landmarks for unincorporated areas, while suburbs designate their own districts under Illinois home-rule authority.
Cook County Code Chapter 102 Article VI creates the Cook County Historic Preservation Commission, which designates Historic Districts and Landmarks within unincorporated Cook. Designation requires Board approval after Commission hearing. Once designated, exterior alterations, demolitions, and new construction visible from public ways need a Certificate of Appropriateness. Suburbs like Oak Park, Evanston, Riverside, and Pullman maintain their own historic districts under separate municipal codes. Statewide, the Illinois Historic Preservation Division reviews National Register nominations. Cook County rules do not apply within incorporated municipalities, which preempt by home-rule.
Unpermitted alterations within designated districts trigger stop-work orders, fines $100 to $1,000 per day, and required restoration. Demolition without Commission review can void permits and bar redevelopment.
