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 includes all provisions of the Municipal Code of Chicago related to construction, plumbing, heating, electrical, fire prevention, sanitation, zoning or other health and safety standards relating to buildings and structures, except provisions enforced exclusively by a city department other than the Department of Buildings.
An electronic copy of the entire Municipal Code of Chicago, including the Chicago Building Code, is available from American Legal Publishing.
