On June 18, 2025, the City Council of Chicago approved an ordinance to amend Title 17 of the Municipal Code of Chicago, the Chicago Zoning Ordinance. The amendment involves changing the current DC-16, Downtown Core District symbols and indications on Map No. 2-F within the area bounded by West Madison Street, South Clark Street, a line 50.65 feet south of and parallel to West Madison Street, and the public alley next west of and parallel to South Clark Street. The reclassification designates this specific area, located at 101-115 West Madison Street and 2-4 South Clark Street, to officially retain its DC-16, Downtown Core District designation. This ordinance became effective upon its passage and due publication.
