Information Request: Freedom of Information Act (FOIA)

Press Enter to show all options, press Tab go to next option

The information you are seeking may likely already be accessible on this website and may not require you to submit a Freedom of Information Act (FOIA) request.

Please navigate this website using the tools on the homepage or Online Services page. If the property for which the records are sought is located in a municipality, please contact the municipality directly for obtaining the records. A list of municipalities and other agencies can be found here.

If you would like to submit a FOIA request, please carefully read the information below. Illinois law requires public bodies to comply with or deny a FOIA request within five business days, unless the time for response is extended for an additional five business days, as allowed under the law. A request for records to be used for a commercial purpose requires a public body to respond within 21 business days.


Please complete the Online FOIA Request Form or you can download the form [PDF] and mail, fax, email, or hand-deliver directly to the department for which the records are being sought.

Please be specific in the nature of your request in order for FOIA Officers to process your request more efficiently. (Illinois law does not require you to submit on the FOIA Request Form, but the request should be in writing). *Electronic records can be requested and will be provided, as allowed under the law.
