Full Breakdown
Chicago's Zoning Ordinance designates specific downtown streets, State, Wabash, Michigan, LaSalle, Randolph, and others, as "pedestrian streets" subject to mandatory design standards under Chicago Zoning Ordinance Ch. 17-4. Any building facade facing one of these streets must abut the sidewalk or sit within 5 feet of it, at least 60% of the facade between 4 and 10 feet high must be clear, non-reflective display windows, and a primary entrance must face the street. Drive-throughs, gas stations, car washes, vehicle sales lots, and strip centers are barred outright on these frontages, off-street parking must be hidden from the street, and vehicle access can only come from an alley, no curb cuts off the pedestrian street itself.
Violations & Fines
Zoning noncompliance blocks issuance of a building permit or certificate of occupancy for the affected project; the Department of Planning and Development enforces compliance at plan review, and correction of the design is required before the permit issues.
