Maine Building Code, Permit and Licensing Information

Updated: May 24, 2024

What is the Current Adopted Maine Building Code?

Maine Uniform Building and Energy Code (MUBEC) applies to all towns within the State of Maine (Maine Uniform Building Code or Maine Uniform Energy Code, see Chapter 1 below).

MUBEC is made up of the following codes and standards:

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 – 2013 (Ventilation for Acceptable Indoor Air Quality)
  • 62.2 – 2013 (Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings)
  • 90.1 – 2013 (Energy Standard for Buildings except Low-Rise Residential Buildings) editions without addenda.
  • E-1465-2008, Standard Practice for Radon Control Options for the Design and Construction of New Low-Rise Residential Buildings.

Maine has adopted these national model codes and standards with amendments.  The amendments are listed in Rule Chapters 1-6 below.

    • Chapter 1 – Administration (Word DOC)
    • Chapter 2 -Third Party Inspectors (Word DOC)
    • Chapter 3 – IBC International Building Code (Word DOC)
    • Chapter 4 – IEBC International Existing Building Code (Word DOC)
    • Chapter 5 – IRC International Residential Building Code  (Word DOC)
    • Chapter 6 – IECC International Energy Conservation Code (Word DOC)

Applicability (statewide, local, limited): LIMITED

Maine adopts the Maine Uniform Building and Energy Code (MUBEC). Enforcement of the code is required for all communities with a population greater than 4,000. The Technical Building Codes and Standards Board which is appointed by the Governor, resolves conflicts between state building and fire codes.  Maine released updated amendments on November 6, 2017, which then became mandatory throughout the state. Maine is another state on a three-year Code cycle, so they will likely adopt the NEC-2020 sometime in 2021.
