14: Chicago Building Code

The Chicago Building Code (CBC) outlines minimum fire, building and structural standards, as well as health and safety requirements, that apply to every building in the city. The Code sets guidelines and requirements based on how a space is used and occupied, and addresses questions such as:

• Is the space used for residential, commercial or industrial purposes?
• How many people use the space?
• What is the maximum number of people allowed inside?
• What types of activities will occur in the space?

CBC’s requirements become more stringent when:

• The number of persons using the space, or occupant load, is large, and
• Use of the space is hazardous.

Once a building is occupied, Fire Code regulations further control use. Beyond the scope of this section is a detailed explanation of the Building Code. Because the Code's requirements are specific to each space, and vary as the use and intensity of use of the space changes, we will highlight the major concerns of the Code with a specific focus on:

• Permits
• Lighting and ventilation requirements
• Water access
• Entrance and exit issues
• Attics and basements
• Artist live/work spaces
• Building inspections

If you are considering a major renovation to or new use inside a space, seek the services of a state-licensed architect. An architect will be able to help you incorporate Code requirements into the design or remodeling.

Additional information and an on-line copy of the Chicago Building Code can be found at this Website, which provides access to a searchable database of the majority, but not all, of the Code. When possible, we have linked to relevant sections or listed where detailed information can be found in the Code.

In addition, the city's Website provides information on Life Safety Issues (LSI) involving new electrical, elevator, energy conservation, plumbing, accessibility and mechanical issues. Click here to access the information.

For detailed information on the Chicago Building Code, please visit the Municipal Reference Collection at the Harold Washington Library, other area Chicago Public Library branches, or the City Clerk (excerpts and amendments only). You can purchase a copy from the Index Publishing Corporation.

As mentioned previously, the Municipal Code Corporation (MCC) offers most of the code on-line free of charge in a searchable database. However, the newer electrical, elevator, energy and plumbing codes are missing.
