Passed 4/24/2008, effective 6/1/2010

As of September 2011, municipalities with 4,000 or more residents must enforce the MUBEC if that municipality had a building code in place before August 2008. If smaller municipalities choose to enforce a building code, they have several options for doing so. See the Codes Adoption History section of this page for more information.

Code Adoption and Change Process

Code Change Process

Code adoptions and amendments originate from the Maine Public Utilities Commission (PUC). The PUC issues a final provisional rule and the order approving the rule through the PUC’s rulemaking process. This also means that the Legislature must approve its final version. The next step is the drafting of a bill that adopts the provisional rule. The rule must be approved by the Attorney Generals’ office before it goes to the Utilities and Energy Committee, which will then hold a public hearing on the bill. Comments can be submitted in writing or in person. The Committee and ultimately the full Legislature revises the rule, accepts it as-is or rejects it completely.

Code Change Cycle

For its commercial energy code, Maine considers the most recent version of 90.1 with positive DOE determination.

Next Code Update

The Technical Codes and Standards Board is currently working on the adoption of the 2015 IECC and ASHRAE 90.1-2013. The board hopes to have these adopted and in place by July 2016.
