Building Code

The Chicago Building Code establishes minimum standards for the construction, alteration, repair, maintenance, and demolition of buildings and other structures in order to protect public health, safety and welfare.

The Chicago Building Code is adopted and amended by the city council. An electronic copy of the Chicago Building Code can be viewed using the link below. Some portions of the Chicago Building Code incorporate model codes and standards. Where available, links to view or purchase these documents are provided.

The Department of Buildings periodically issues clarifications and interpretations of the Chicago Building Code to provide guidance on frequently-encountered issues. Pursuant to Section 13-8-031 of the Building Code, formal intepretations issued by the Building Commissioner have the force of law.
