Beginning July 1, 2010, builders must use the amended 7th Edition code.

In accordance with the statutory requirements of the Green Communities Act of 2008, the Board of Building Regulations and Standards (BBRS) has amended the 7^th Edition State Building Code (780 CMR). As of January 1, builders must use the 2009 IECC with MA amendments. BBRS is allowing a 6-month concurrency period, through June 30, 2010, during which either the previous code (the 2006 IECC with the 2007 IECC Supplement and MA amendments) or the new code may be used. Commencing July 1, 2010, the baseline energy conservation requirements of the State Building Code will default to IECC 2009 and MA amendments. The MA changes to the IECC can be found by referring to Chapters 13, 34, 61 and 93 amendments posted on the BBRS website.
