Ninth Edition Building Code 

Amendments to the Energy Portions Effective Date. 

The Board of Building Regulations and Standards (BBRS) has voted to amend the building code 9th by adopting the 2018 International Energy Conservation Code (IECC) with Massachusetts amendments. The Secretary of State has assigned February 7, 2020, as the effective date. A version of the amendments is available on the Office of Public Safety and Inspections webpage:   


The amendments can be viewed

Ninth Edition Base Code – Chapter 13

Stretch Energy Code  - Appendix AA

Ninth Edition Residential Code – Chapter 11


In updating the 9th edition energy code, the BBRS actions included granting time to adjust to the updated code. For this reason, the BBRS voted that building permit applicants can elect to utilize the energy code provision in the 2015 IECC along with the Massachusetts amendments until August 7, 2020, at which time this option will conclude.
