Electrical Contractor Licensing in Maryland

  • SumoMe

Electrical Contractors working in the State of Maryland are required to obtain a license.  Licenses are issued by the Maryland State Board of Master Electricians, which is part of the Division of Occupational and Professional Licensing, within the Department of Labor Licensing and Regulation (DLLR).

As part of the licensing process, contractors are required to prove that they meet the Board’s requirements for work experience and pass a qualifying examination.

Various counties and jurisdictions within the state also require local-licensing in order to perform electrical work.  Therefore, it is important that all contractors also check with their local jurisdiction to determine the local licensing requirements.

License Classifications for Electrical Contractors in Maryland

The Board offers only one license classification to Electrical Contractors in the State of Maryland:
