The Building Department Records site allows you to view records related to building permits, inspections, violations and enforcement actions for a specific address. The Building Permit Application Status site lets you check the status of a pending building permit application. The Vacant Building Registration site lets you search for information about vacant buildings registered with or inspected by the Department. The Buildings section of the City’s data portal provides bulk data about all building permits and building violations since 2006. Information about city employees, maintained by the Department of Human Resources, is also available on the data portal.

If you submit a FOIA request for records that are available to the public online, you will be provided with links to these sites.


The Freedom of Information Act (FOIA) is a state law that provides citizens with access to public records.  Each City department is a separate agency responsible for maintaining its own records, so requests should be submitted to the department that maintains the records you want.

All FOIA requests submitted to City of Chicago departments must include the following information:

  1. The name, mailing address and contact information of the requester;
  2. A description of the records that are being requested.

Please note that all FOIA requests are posted online.  FOIA requests are public information, and when you submit a FOIA request, your name and information about the request will be made available on the City's website.

Please be specific about the information you are seeking, and indicate the exact locations and dates.  Please indicate in your request how you would like the information sent to you (via email, mail, or available to pick up at our office).

The first 50 pages of photocopies are free of charge*, with each additional page $.15.
