Chicago FAQ
How are buffers measured in Chicago?
Distances run property line to property line along the shortest pedestrian path, not radius. Planning staff verify measurements during special use intake before the Zoning Board of Appeals hearing.
Does a new school nearby close my dispensary?
Lawfully approved dispensaries predating the school generally continue operating, but any expansion, relocation, or ownership change requires the buffer to be retested under current MCC 17 rules.
Oak Lawn FAQ
How is the 1,500-foot buffer measured?
Cook County Building and Zoning measures from the cannabis premises property line to the nearest property line of the sensitive use along the shortest accessible path, not as a circular radius and not from door to door.
Do Cook County buffers apply inside cities?
No. Ch. 102 buffers only apply in unincorporated Cook County. Each suburb sets its own buffers, and many Cook suburbs adopted larger 1,500 to 2,500-foot setbacks under the CRTA opt-in framework.
