Zoning Classification Search
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).
Map Amendment Application
A “map amendment” is a change in zoning classification from the Cook County Comprehensive Land Use Map.
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.
