Maryland Contractor & Trade License Requirements

Maryland requires statewide licensing across all major trades. The Maryland Home Improvement Commission (MHIC) licenses all contractors performing residential improvement work. Electricians are licensed by the State Board of Master Electricians, plumbers by the State Board of Plumbing, and HVAC contractors by the Board of HVACR Contractors. Roofing contractors performing residential work must hold an MHIC license. All boards operate under the Maryland Department of Labor, Division of Occupational and Professional Licensing.
