The Department of Building and Zoning allows you to review the current zoning classification of parcels located in unincorporated Cook County (only). In order to learn a property's zoning classification, you must enter the property's fourteen (14) digit permanent real estate index number (PIN).
The Zoning Classification Search is down for planned maintenance and is not available at this time. Please feel free to contact Building & Zoning if you have any questions in the interim.
Map Amendment Application A "map amendment" is a change in zoning classification from the Cook County Comprehensive Land Use Map.
Variation Application A “variance” means a grant of relief from the requirements of the Cook County Zoning Ordinance which permits construction in a manner that would otherwise be prohibited by the Ordinance.
Special Use Application A “special use” of land or buildings, or both, described in the Cook County Zoning Ordinance is a use subject to special provisions because of unique characteristics that do not allow the use to be properly classified as a permitted use.
