Tenth Edition CMR 780
The tenth edition building code was filed with the Secretary of State on Tuesday, September 24, 2024 and became effective on October 11, 2024.
The 9th Edition of the Building Code will apply concurrently with the 10th Edition until June 30, 2025. Building permit applications for projects utilizing the 9th Edition need to be filed on or before June 30, 2025. Applications received on or after July 1, 2025, that are based on the 9th Edition will not be accepted and will not be granted a building permit. Breaking ground on a jobsite does not need to begin immediately when obtaining a permit. However, if breaking ground does not commence within 180 days of a permit being issued, the permit may expire unless extended. See 780 CMR 105.5 for more information.

- The International Building Code (IBC);
- International Residential Code (IRC);
- International Existing Building Code (IEBC);
