In order to effectively protect the public health, general welfare, and safety of the citizens of Cook County, the County Board has determined that businesses operating in Unincorporated Cook County will be required to obtain a Cook County General Business License.
This new requirement will allow the County Government to ensure businesses operating in Unincorporated Cook County, are in compliance with public health and public safety standards, as well as with all other County ordinances. This will prevent illegal businesses from negatively influencing legitimate commerce and protect consumers from bad business practices.
Some users may experience difficulty registering using the online system. If you are unable to complete the application for any reason or if you have additional questions, please contact Richard Crusor at (312) 603-3634 or by email Richard.Crusor2@cookcountyil.gov.
