Minnesota Mechanic Lien Law Overview

Last updated April 2026 · Reviewed by Thomas Emalfarb, Esq.

Minnesota construction mechanic lien rights are governed by Minnesota Statutes Annotated M.S.A. §514.01 et seq. This statutory framework protects the payment rights of general contractors, subcontractors, sub-subcontractors, and material suppliers who furnish labor, services, or materials for the improvement of real property in the State of Minnesota.

A key feature of Minnesota mechanic lien law is the distinction between contractors with written contracts and those without. For written contracts, the contract itself must include a statutory notice prescribed by M.S.A. §514.0011(1). Contractors without a written contract must provide written notice to the owner within 10 days after the work of improvement is agreed upon under M.S.A. §514.0011(2).

Subcontractors, materialmen, and sub-subcontractors must serve a Pre-Lien Notice (Notice to Owner of Potential Claims) within 45 days of first performance under M.S.A. §514.011(2). This notice must include prescribed statutory wording. Note that the pre-lien notice requirement generally applies to residential projects and commercial projects under 5,000 square feet — legal consultation is recommended to determine applicability on larger commercial projects.

Minnesota also provides payment bond claim procedures for public works projects under M.S.A. §574.26 et seq., requiring performance and payment bonds for the full amount of the contract with limited exceptions.
