Reminder – Concurrency Period for 9th Edition ends June 30, 2025!

Code (Red) Alert! For those continuing to design buildings in accordance with the 9th Edition of 780 CMR, the Massachusetts State Building Code, time is running out to file your permit applications. Starting July 1, 2025, all projects filing for building permits in the State of Massachusetts must comply with the 10th Edition of the Massachusetts State Building Code (780 CMR), which is based on the 2021 International Building Code. Code Red Consultants will post informative blog posts in the coming weeks to assist you with this transition. These posts will provide a summary of some of the key impactful code changes in the 10th Edition, including Laboratory Suites, adoption of NFPA 4 Integrated Testing of Fire Protection Systems, occupant load factor changes in business occupancies impacting egress calculations, fire alarm low-frequency devices, mass notification systems, and more.

Have questions on how these code changes impact your projects? Please reach out to discuss!
