New Information Regarding the 10th Edition of 780 CMR

Earlier this spring, we issued an update regarding the 10th edition of the Massachusetts State Building Code (780 CMR) with an anticipated promulgation to occur by mid-2020, in which the 2018 editions of the I-Codes (IBC, IEBC, IMC, and portions of the IFC) were planned to be adopted. However, as of June 11th, the Board of Building Regulations and Standards (BBRS) voted to redirect efforts and table the current code adoption proceedings regarding the 10th Edition of the 780 CMR, and agreed to the following goals:

  1. The 10th Edition of 780 CMR will adopt the 2021 Editions of the I-Codes.
  2. The 10th Edition of 780 CMR will have an effective date of January 1st, 2021.
  3. Massachusetts will adopt new building codes on a 3-year cycle moving forward.

Another outcome of the 10th Edition re-direction is that the state’s code adoption process will also better align with the ICC’s code development schedule, which now allows the Massachusetts State Building Code to implement the latest versions of the I-Codes. Historically, 780 CMR has incorporated editions that have typically been between 3 – 6 years behind the latest edition of the I-Codes.

An important note is that the change in direction does not affect the promulgation of the 2018 Edition of the International Energy Conservation Code (IECC). This code will still become effective on January 1, 2020, as required by Massachusetts General Law Chapter 143, Section 94 (o).
