Several parties involved in a construction project may file a mechanic’s lien in Maryland. This includes general contractors, subcontractors, and material suppliers. However, architects, engineers, and surveyors may also be eligible if their work contributes directly to improving the property. If you are a contractor or supplier in Maryland, you must file your lien within the statutory deadlines and meet other legal requirements. Failure to do so may result in the forfeiture of your right to file a lien.
