Ninth Edition of the State Building Code Update

(780 CMR)

Manufactured Buildings Notice

Ladies and Gentlemen –

As you may be aware, the Ninth Edition of the State Building Code (780 CMR) is complete. The new, ninth edition code is based on modified versions of the following 2015 codes as published by the International Code Council (ICC).

  •          The International Building Code (IBC);
  •          International Residential Code (IRC);
  •          International Existing Building Code (IEBC);
  •          International Mechanical Code (IMC);
  •          International Energy Conservation Code (IECC);
  •          International Swimming Pool and Spa Code (ISPSC);
  •          Portions of the International Fire Code (IFC).

The 2015 International codes may be viewed @ I-Codes.  The Massachusetts amendments for the base code may be viewed @ Base Code Amendments and the residential code amendments may be viewed @ Residential Code Amendments.

What does that mean for manufactured building designs?

Any manufactured building project utilizing eighth edition code provisions will need to have been assigned a BBRS Approval Number on or before December 31, 2017. Any project with a BBRS number issued on or after January 1, 2018 will be expected to comply with the ninth edition of the code.

Due to statutory obligations, the one exception to this message is that the 2015 IECC went into effect on August 12, 2016 as an amendment to the Eighth Edition.

We will continue to provide updated information over the next several weeks as it becomes available. In the interim, it is hoped that this information is helpful.
