2012 International Energy Efficiency Code (IECC) Takes Effect in Massachusetts

Monday, August 25, 2014

When the Board of Building Regulations and Standards (BBRS) voted to promulgate the 2012 IECC in July 2013, it was adopted with a 1-year concurrency period.  This concurrency period has officially ended, meaning that the 2012 IECC is now mandatory.

This update does not affect the Massachusetts Stretch Energy Code, which is still based on the 2009 IECC with Massachusetts amendments.  The BBRS has not yet made any formal decisions as to whether a new Stretch Code will be adopted.  Until such a decision is made, the following code editions will apply:

    In communities that have adopted the Stretch Code, the 2009 IECC with Stretch Code amendments applies to projects within the scope of the current Stretch Code (i.e. most new construction and alterations to existing residential buildings).  The 2012 IECC applies to all other projects (i.e. alterations to existing non-residential buildings and new buildings that are exempt from the Stretch Code).

      In communities that have not adopted the Stretch Code, the 2012 IECC applies to all projects (new construction and alterations).
