Only 6 states out of 50 have made the 2012 IECC Effective, Illinois, Maryland, Massachusetts, Rhode Island, Utah, Washington

According to the International Code Council (ICC), only a handful of states have implemented the 2012 International Energy Conservation Code (IECC) as of October 2013. While the majority of states lag behind in implementation, more populous states with a larger chunk of the construction market tend to adopt new IECC measures first. With the aggressive 2015 IECC looming in the background, anticipate wider implementation of the 2012 IECC to snowball.
