Zoning Applications

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.
