Building Permits

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.
