The tenth edition building code of the Massachusetts State Building Code is now in effect. The Building Code is found in the Code of Massachusetts Regulations at 780 CMR 1.00 to 115.00. The primary structure of the 10th Edition Building Code is based upon adoption of the 35 chapters and appendices of the 2021 International Building Code (IBC). Select chapters of the IBC have been replaced with Massachusetts specific amendments as well as other I-Codes.
A new chapter 51 has been added, this chapter is entitled the Massachusetts Residential Code and adopts the 2021 International Residential Code with Massachusetts specific amendments.
Massachusetts amends the I-Codes fairly significantly to accommodate for unique issues in the Commonwealth.
