The Board of Building Regulations and Standards (BBRS) has completed a review of the public comments and will likely vote to promulgate the 10th Edition of 780 CMR, the Massachusetts State Building Code at their next meeting on May 14, 2024. If that occurs, the effective date of the new building code will likely be in June 2024. The BBRS also voted to allow a concurrency ending on December 31, 2024 (regardless of when the 10th Edition formally goes into effect). During this concurrency period, projects can elect to file permits under either the 9th or 10th Editions. Projects filing for permits on or after January 1, 2025, will be subject to compliance with the 10th Edition. The table below shows a comparison of key model codes that are adopted and amended by each Edition.
