For certain construction projects, you need oversight from a licensed construction supervisor. Find out more below.

Overview

For 1- and 2-family homes and\or appurtenant structures of any size

  • A licensed construction supervisor or a registered design professional (RDP) must oversee construction.  (See 780 CMR, Chapter 1 for home owner exemption language.)

For most existing 1- to 4-family owner-occupied homes

  • A licensed construction supervisor or a registered design professional (RDP)  must oversee construction.  (See 780 CMR, Chapter 1 for home owner exemption language.)
  • A contractor must also register with the home improvement program.

For buildings less than 35,000 cubic ft. of enclosed space

  • A licensed construction supervisor or registered design professional (RDP) must oversee construction, including for manufactured buildings.

For buildings greater than 35,000 cubic ft. of enclosed space

  • A registered design professional (RDP) - engineer or architect - must control the construction of larger buildings.
  • A construction supervisor license is not required for larger projects since the RDP is considered the licensed person for the project.
  • Always check with the municipal building official in the city\town in which the project is located for additional licensing requirements.                       

Out of state contractors

  • Massachusetts does not recognize out of state contractor licenses.             
  • 780 CMR (The Massachusetts Building Code) applies to all buildings and structures in the Commonwealth.
