Maine State Codes encompasses a comprehensive set of laws and regulations governing various aspects of life in the state of Maine. These codes cover areas like transportation, education, environmental protection, and labor practices, shaping the legal landscape and providing guidelines for citizens, businesses, and government agencies. Understanding and adhering to Maine State Codes is essential for individuals and organizations to navigate the legal framework of the state effectively.

Code Adoption and Change Process
Code Change Process
Code adoptions and amendments originate from the Maine Technical Codes and Standards Board (TCSB), which is part of the Department of Public Safety. The TCSB issues draft and final rules through their ordinary rulemaking process, which includes public comment. The rule also must be approved by the Attorney Generals’ office to ensure legal and procedural compliance. The law requires the TCSB to maintain an adoption cycle such that codes do not lapse more than 5 years or one national model code version cycle.
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 for commercial buildings. The 2009 IECC will continue to apply to residential buildings. As of February 2017, the board is waiting for a return of Rules for Rule-Making from the Governor’s Office and will have a Public Hearing as soon as they receive them back.

|Two other bills addressing the MUBEC are considered by the Committee on State and Local Government. LD 1416 would return the power of adopting building codes to municipalities, shrinking the statewide application of the MUBEC. LD 1442 would clarify enforcement of the MUBEC and reaffirm its position as the statewide construction code.
|January 11, 2011
|A bill (HP 36 LD 43) was introduced in the Maine Legislature that would repeal the Maine Uniform Building and Energy Code (MUBEC). A hearing on the bill is scheduled for April 7 before the House Committee on Labor, Commerce, Research and Economic Development. On April 14th, House Committee on Labor, Commerce, Research and Economic Development of the Maine Legislature votes that this bill ought not to pass. Other legislation has also been introduced to delay, modify, or alter the application of the MUBEC.
|June 1, 2010
|After the legislative establishment of the Maine Uniform Building and Energy Code (MUBEC) in April 2008 by LD 2257 (enacted as P.L. 699), the Bureau of Building Codes and Standards (within the Department of Public Safety) issues regulations setting the 2009 IECC and ASHRAE 90.1-2007 as the mandatory energy standards for residential, commercial, and public buildings statewide. The MUBEC becomes effective on this date. There will a six-month transition period during which towns may still enforce their previous codes. Among the new rules:
|The completed Climate Action Plan is submitted to the legislature.
|The Maine State Legislature passes a bill that requires the DEP to develop a climate action plan with the goals of reducing emissions.
|PL 503, “The Energy Building Performance Standards Act,” establishes 10 MRSA, Chapter 214, which directs the Office of Energy Resources (OER) to adopt voluntary energy standards for residential and commercial new construction and substantial renovations. In 1980, the legislature adopts the voluntary standards into law.
|The state legislature adopts what is now Chapter 57 of the Private and Special Laws, which directs the OER to establish the Maine Commission on Energy Efficiency Building Performance Standards (the Commission). The Commission is directed to investigate energy building standards and make recommendations to the next biennial legislature.
