Because upgrades to the City's online permit application system have been delayed until at least 2023, the Department of Buildings has prepared step-by-step instructions to help customers start permit applications for projects subject to the 2019 Chicago Construction Codes: Online Building Permit Application Instructions.

By following these instructions, you will avoid unnecessary data entry on your part and help city staff to review and process your permit application more efficiently. 

Thank you for your patience and cooperation during this transitional period.
