The City of Chicago does require building permits for most construction projects to ensure that our buildings are safe and comply with the Chicago Construction Code.

​

The Department of Buildings has a robust website that can help a variety of users navigate the process of when to apply for a permit, how to apply for a permit, and estimate the costs of a permit. 

 

The Department of Buildings also has a concise Guide to Permits, which provides an overview of the permit processes for small and mid-size projects.
