Construction Codes

The Chicago Construction Codes establish 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 Construction Codes are adopted and amended by the city council. Electronic versions of the Chicago Construction Codes can be accessed using the link below.
