The Bureau of Building Codes and Standards was created in 2010 under Title 25 §2372 to provide administrative and technical support to the Technical Building Codes and Standards Board. The BBCS also provides non-binding technical interpretation of the codes for professionals and the public.

Maine Uniform Building and Energy Code

Maine Uniform Building and Energy Code (MUBEC) applies to all towns within the State of Maine. Enforcement of MUBEC is based on population or local action for communities under 4,000 residents as outlined in Chapter 1 (see below "MUBEC Rules and Laws.")

MUBEC is made up of the following codes and standards:

  • 2015 International Residential Code (IRC)
  • 2015 International Building Code (IBC)
  • 2015 International Existing Building Code (IEBC)
  • 2015 International Energy Conservation Code (IECC)
  • 2015 International Mechanical Code (IMC)

The following standards are also adopted as part of the MUBEC, and are mandatory.

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standards:

  • 62.1 - 2016 (Ventilation for Acceptable Indoor Air Quality)
  • 62.2 - 2016 (Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings)
