In July 2013 the Board of Building Regulations and Standards (BBRS) approved the International Energy Conservation Code 2012 (IECC 2012) with MA amendments as the new baseline energy code, effective August 16, 2013.  An unofficial version of the MA amendments is found at Building Code/BBRS .   

These new regulations ran concurrently with the IECC 2009 until July 1, 2014.  Since that date the IECC 2012 applies to all buildings except those governed by the Stretch Code, which still uses the IECC 2009.
