Massachusetts building codes

Massachusetts regulates construction through the State Building Code (780 CMR), promulgated by the Board of Building Regulations and Standards. The 8th Edition adopted the 2009 International Codes as its base, with Massachusetts amendments, effective August 2010 until the 9th Edition took effect in October 2017. Massachusetts regulates plumbing and certain trades under separate state codes rather than the ICC IPC/IMC.

Where verbatim source text is shown, it is reproduced from the code as adopted into law by the jurisdiction, sourced from public.resource.org under the government edicts doctrine (see Georgia v. Public.Resource.Org, Inc., 590 U.S. 255 (2020)). This material reflects enacted law and is provided for reference and educational purposes only. It is not legal advice and may not reflect local amendments or the most recently adopted edition. Always verify requirements with the authority having jurisdiction.
