Chicago permit and inspection research
Separate public building-record research from the account-based tools used to manage applications. Identify the subject address and any associated addresses before interpreting the results.

01
Use the public building-record search
Chicago’s Building Permit and Inspection Records website provides public access after its user agreement. Locate the property and review the available permit and inspection entries. Save the record identifiers so a later request can be specific.
02
Read the status, not just the permit title
For a proposed acquisition or construction draw review, identify what the record actually documents. An application or permit entry does not independently demonstrate that the work was completed, inspected, or accepted. Reconcile the public entry with project records and follow up on unexplained gaps.
03
Keep applicant tools separate
The Inspection, Permitting & Licensing Portal is used to manage a range of permits, inspections, and licenses through an account. Its presence does not mean a third-party researcher will have access to the applicant’s complete file. Obtain missing documents from the responsible party or agency through the appropriate process.
