Use Permits

A Use Permit is required for changing the use of a property and/or structure. A Site Development Permit may also be required depending on the site conditions. Applicability will be determined by staff at the time of permit application. A special inspection is required (sometimes prior to application) to determine if the proposed use will meet all the applicable codes. Please call the Building and Code Enforcement office at 847-377-2600 to schedule a special inspection.

Some of the examples of change of use are:
  • Conversion a retail store to office space
  • Conversion of office space to a restaurant
  • Changing a residential use to a commercial use
