MA Plumbing Code Update

At the most recent Board of State Examiners of Plumbers and Gas Fitters meeting, the Board voted to finalize the proposed amendments for 248 CMR 10.00. The promulgation of such code will likely be as soon as 2023.

Draft amendments were discussed in the Board’s April 2022 open listening meeting. Some of the draft changes include:

  • In places other than residential, restrooms will have a travel distance of 400 feet and in multi-story buildings, access to the restroom is limited to one vertical story.
  • New minimum plumbing fixture factors for places including greenhouses, bed & breakfasts, and public beaches.

These updates are not yet finalized, however may impact designs so designers should be mindful of its approaching promulgation.

Code Red will continue to monitor the adoption process of the next edition of 248 CMR 10.00 and update this post as more information becomes available. For additional information or request for assistance on your project, please contact us at
