Why do I need a building permit?

A permit is required before beginning most types of construction, demolition, and repair work in Chicago. Permits issued by the Department of Buildings (“building permits”) help to ensure building construction, rehabilitation, and demolition work complies with the minimum standards established by the Chicago Construction Codes and Chicago Zoning Ordinance to protect and enhance public health, safety, and quality of life.

Before issuing a building permit, the Department of Buildings verifies that the contractors identified in the permit application have the proper qualifications and insurance. Throughout the process of permit application review and inspections, you and everyone working with you on your project have access to input and advice from experienced reviewers and inspectors committed to upholding these public safety standards.
