New building codes take effect in Maine

MAINE PUBLIC • April 7, 2025

New building codes take effect Monday in Maine. The State Fire Marshal's Office and Governor's Energy Office want builders, residents, architects, and municipalities to understand the changes. The new codes are intended to ensure that buildings moving forward meet updated structural integrity, energy efficiency, and indoor air quality standards. Among the changes are the requirement to use more insulation in floors and walls to improve energy efficiency that the U.S. Dept of Energy estimates will save homeowners hundreds of dollars on their utility bills.
