Massachusetts Construction Code and Edition Adopted:

Massachusetts Construction code is based on the 2015 IBC, IRC, IEBC, IMC, and ISPSC, as well as the 2018 IECC. There are references to the 2015 IFC.  Massachusetts is home to NFPA, which produces the NEC, so it is usually the first state to adopt the National Electrical Code at the beginning of each code cycle. This adoption is across all local jurisdictions as required by regulations and statute.

  • 2015 International Building Code (IBC)
  • 2015 International Residential Code (IRC)
  • 2018 International Energy Conservation Code (IECC)
  • 2020 National Electric Code (NEC)
  • 2015 International Existing Building Code (IEBC)
  • 2015 International Mechanical Code (IMC)
  • 2015 International Fire Code (Portions, not fully adopted)
  • 2015 International Swimming pool and Spa Code

Applicability (statewide, local, limited): STATEWIDE

Massachusetts Building Code is approved and administered by the Board of Building Regulations and Standards (BBRS), consisting of eleven members and is staffed by the Department of Public Safety. The Board of Fire Prevention Regulations (BFPR) is a fourteen member board responsible for promulgating a comprehensive fire safety code (527 CMR) for the Commonwealth of Massachusetts. The BBRS is responsible for reviewing and recommending which building codes are adopted in Massachusetts. Additionally, the members of the BBRS comprise the Building Code Appeals Board for purposes of deciding appeals of interpretations of the Building Code made by building officials and other similar officials. Amendments may be made by jurisdictions with State approval.
