Chicago Landmark is a designation of the
Mayor of Chicago and the
Chicago City Council for historic buildings and other sites in
Chicago,
Illinois,
United States. Listed sites are selected after meeting a combination of criteria, including
historical,
economic,
architectural,
artistic,
cultural, and
social values. Once a site is designated as a landmark, it is subject to the Chicago Landmarks Ordinance, which requires that any alterations beyond routine
maintenance, up to and including
demolition, must have their
permit reviewed by the
Landmarks Commission. Many Chicago Landmarks are also listed on the
National Register of Historic Places, providing federal tax support for preservation, and some are further designated
National Historic Landmarks, providing additional federal oversight.
