What Is a Mechanics Lien in Michigan — Complete 2026 Guide
Michigan mechanics lien law under the Construction Lien Act (MCL 570.1101 et seq.) requires subcontractors to serve a Notice of Furnishing within 20 days of first furnishing. The filing deadline is 90 days from last furnishing. Enforcement must begin within 1 year of filing.
Michigan 20-Day Notice of Furnishing
Michigan subcontractors, sub-subcontractors, and material suppliers must serve a Notice of Furnishing on the property owner and the general contractor within 20 days of first furnishing labor or materials on the project. Failure to serve the Notice of Furnishing within 20 days limits lien rights to work furnished within 20 days before the notice was served. Michigan's 20-day window is one of the tightest preliminary notice deadlines in the country.
Michigan 90-Day Filing Deadline
After last furnishing labor or materials, Michigan Construction Lien Act claimants have 90 days to record a construction lien (Michigan's term for a mechanics lien) with the Register of Deeds in the county where the project is located. This 90-day deadline applies to contractors, subcontractors, and material suppliers alike.
Where to File in Michigan
Michigan construction liens are filed with the Register of Deeds in the county where the project property is located. Major filing offices include the Wayne County Register of Deeds (Detroit), Oakland County, Macomb County, and Kent County (Grand Rapids).
Michigan Lien Enforcement — 1 Year
After recording a construction lien in Michigan, the claimant must enforce the lien by filing a lawsuit to foreclose within 1 year of the date the lien was recorded. Michigan's 1-year enforcement deadline gives claimants adequate time to negotiate while maintaining urgency. The Mechanics Lien Management State System calculates all Michigan deadlines.
