A Minnesota mechanic’s lien is a document used by unpaid contractors to file a claim against an owner’s property and demand compensation. General contractors, material suppliers, consultants, architects, and nearly any party who provides services or supplies on a construction project are entitled to lien rights. If the property owner fails to pay the debt, the mechanic’s lien may be enforced, and a foreclosure lawsuit may be filed against the property (this is usually the last resort).

To obtain lien rights, general contractors must provide a General Contractor’s Notice within ten (10) days of the initial contract; subcontractors and suppliers must provide a preliminary notice within forty-five (45) days of the commencement of work.
