Maine Contractor & Trade License Requirements
Maine does not require a statewide license for general contractors or roofing contractors. The state licenses electricians through the Electricians' Examining Board, plumbers through the Plumbers' Examining Board, and HVAC/oil burner technicians through the Maine Fuel Board — all under the Office of Professional and Occupational Regulation (OPOR). Maine participates in the National Electrical Reciprocal Alliance (NERA) for electrician license reciprocity.
