Stringency: The Maine Uniform Building and Energy Code (MUBEC) was established legislatively in April 2008 through P.L. 699. On June 1, 2010, the 2009 IECC and ASHRAE 90.1-2007 became mandatory for residential, commercial, and public buildings statewide, though enforcement varies by population. In 2011, P.L. 408 changed mandatory compliance requirements for the Maine Uniform Building and Energy Code (MUBEC) to municipalities with populations over 4,000. Therefore, towns with a population less than 4,000 are not required to enforce the code. Towns with a population of 4,000 that had a building code as of August 1, 2008 were required to begin enforcing the new codes December 1, 2010. Towns with a population of 4,000 but did not have a building code as of August 1, 2008, will be required to begin enforcing the new codes December 1, 2012. This change means that only 89 of Maine’s 533 municipalities (based on 2010 census data) are required to comply with energy efficiency codes, which means the requirement applies to approximately 60% of the state’s population. Smaller municipalities may adopt the uniform code, but are not required to. In 2013, LD 977, which would return to the 2,000 population threshold, was introduced and is making its way through the legislative process.
Compliance (2013 Survey Responses):
- Gap Analysis/Strategic Compliance Plan: NA
- Baseline & Updated Compliance Studies: NA
- Utility Involvement: NA
- Stakeholder Advisory Group: NA
- Training/Outreach: A training and certification program was launched simultaneously with the building energy code changes in 2010. All code officers are required to be certified and training is provided free of charge. Builders, architects and others are not required to be certified, but are encouraged to attend the training on a fee basis.
