Massachusetts Building and Residential Codes

The ninth edition building code of the Massachusetts State Building Code (MSBC – 780 CMR) became effective on October 20, 2017.  The MSBC is based on the 2015 I-Codes published by the International Code Council (ICC), and state-specific amendments adopted by the Board of Building Regulation and Standards (BBRS).  It consists of the Residential volume which regulates all one and two family structures and townhouses that are three stories or less, and the Base volume which regulates all structures that are not covered by the Residential regulations.  The BBRS regularly updates the state building codes as new information and technology becomes available and change is warranted.
