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.
