Building Stretch Code Update

Stretch Code and Specialized Opt-In Code Published

After a year working on the code development process,  on December 23rd, DOER’s updated Stretch Code and new Specialized Opt in Code (collectively, 225 CMR 22 and 23) were officially published the Secretary of State register. As a reminder, An Act Creating a Roadmap to Net Zero by 2050 required DOER promulgate a new Specialized Opt-in Code to be available for municipalities to adopt. Today, the new Specialized Opt-in Code is available for adoption. DOER has released guidance and model language for cities and towns seeking to adopt this new code. The specialized opt-in code builds on the energy efficiency requirements of Stretch Energy Code and requires any building using fossil fuel to be electrification-ready and install on-site renewables where feasible.

The new stretch code, which will apply in the 300 cities and towns across the state who have adopted the Stretch Code as part of the Green Communities Program is also finalized. Medway has been designated a Green Community since 2010, and stands proudly as one of the initial groups of communities to adopt the program. At this time, Medway is not pursuing the Special Opt-In Code.  

You can find detailed code language at the DOER website. Official published copies of this language is also available from the Secretary of State bookstore. 

The requirements of the new stretch code phase in over time beginning in January 2023. More detail on the requirements and effective dates of the updated Stretch Code are also available in DOER’s November 2nd informational webinar slides and a recording available for review.

Thank you for your engagement during 2022 on the code development process and we look forward to continuing to work with you all in 2023.
