As of January 2015 Chicago will be the only community left in the metropolitan area, as well as the only major US city, that does not use a current model building code for fire and life safety.
On November 19, 2014 the Cook County Board of Commissioners officially approved the ordinance that will update their building codes for unincorporated areas by adopting the 2009 International Residential Code (IRC) for one and two-family dwellings, the 2009 International Building Code (IBC) for multiple dwellings and commercial, and the 2012 International Mechanical Code (IMC). The new Cook County Electrical Code is a combination of three electrical codes: the 1997 Cook County Building and Environmental Ordinance (which was taken from the 1970 Chicago Electrical Code), the current Chicago Electrical Code (from 1999), and the 2011 National Electrical Code (NFPA 70). All should be available on the Municode.com website soon and will be made effective on January 5, 2015. The 2014 Illinois Plumbing Code and the 2012 (Illinois) International Energy Conservation Code (IECC) have and will continue to govern work in the County.
