What is a Certificate of Occupancy?

A Certificate of Occupancy, also known as a "CO," is a document issued by a local government agency that certifies that a building or structure is safe and habitable for its intended use. In Chicago, the Department of Buildings is responsible for issuing Certificates of Occupancy.

Why do I need a Certificate of Occupancy in Chicago?

In Chicago, a Certificate of Occupancy is required for any new construction, addition, or alteration to a building or structure. It is also required when a property changes use, such as when a commercial property is converted to a residential property.

A Certificate of Occupancy is an important document because it ensures that a property meets the minimum safety and zoning standards set by the city. It is also a legal requirement for the transfer of ownership of a property and is often required by lenders and insurance companies.

How do I obtain a Certificate of Occupancy in Chicago? The process of obtaining a Certificate of Occupancy in Chicago involves several steps, including obtaining the necessary Chicago Building Permits and completing required inspections. Here is a general overview of the process:

  1. Obtain the necessary Chicago Building Permits: Before starting any construction or renovation work, you must obtain the necessary Chicago Building Permits. This includes a construction permit, which allows you to begin the work, and an occupancy permit, which allows you to occupy the finished space.


  1. Complete the required inspections: As you complete different stages of the construction or renovation work, you will be required to have inspections performed by the Department of Buildings. These inspections ensure that the work meets the minimum safety and zoning standards set by the city.



  1. Submit a Certificate of Occupancy application: Once the construction or renovation work is complete and all required inspections have been performed, you can submit a Certificate of Occupancy application to the Department of Buildings. This application must include all necessary documents, such as building plans and inspection reports.


  1. Wait for the Certificate of Occupancy to be issued: The Department of Buildings will review your application and, if all requirements are met, will issue a Certificate of Occupancy. This process can take several weeks, depending on the complexity of the project.
