A mechanic's lien is a legal document used by contractors, subcontractors, and suppliers to secure payment for work completed on a construction project. Filing a mechanic's lien essentially states that:
- You're owed money for services provided
- You're expecting payment by a specific date
- You'll proceed with litigation if you don't receive payment by that date
While a lien is in place, it restricts the owner from selling, refinancing, or transferring the property without paying you. That pressure makes liens one of the most powerful payment tools available—especially for subcontractors and suppliers.
Mechanic's lien laws vary significantly by state, with different rules governing who can file a lien, what notices are required, and timelines for filing and enforcement. This guide covers the essentials of Minnesota's mechanic's lien laws to help you protect your right to payment.

Governed by Minnesota Statutes §§ 514.01 through 514.17, Minnesota mechanic's lien rights apply only to private construction projects. (Public projects cannot be liened in Minnesota. If you are unpaid on a public job, your remedy is through a payment bond claim under Minnesota's public bonding statutes, not a mechanic's lien.)
Minnesota has a notice-driven lien system. Most parties must send an early preliminary notice to the property owner to preserve lien rights, and missing that step can completely bar a lien. Additionally, lien rights are limited to how much the owner still owes under the prime contract at the time the notice is received.
With those guardrails in mind, let's break down who has lien rights and how the process works.
In Minnesota, mechanic’s lien rights extend to parties who contribute to the improvement of real private property, including:
- General (original) contractors
- Subcontractors and lower-tier subcontractors
- Material suppliers and vendors
- Laborers and tradespeople
- Engineers or land surveyors
- Equipment and machinery providers
- Miners and parties working on qualifying utility or line projects
To be eligible for a mechanic's lien in Minnesota, your work must fit into the approved lienable work category for updates to real estate. Here are some examples of work that fall into that category and others that don’t.
Lienable Work in Minnesota
- Construction, alteration, repair, or removal of buildings or structures
- Engineering and land surveying services
- Excavation, grading, filling, and site preparation
- Landscaping, sod, soil, trees, shrubs, and planting labor
- Installation or repair of utilities, pipes, conduits, sewers, and drainage
- Sidewalks, curbs, paving, gutters, and related work
- Railways, pipelines, telecommunication, and utility lines
- Labor, materials, or machinery furnished for a qualifying improvement
Non-Lienable Work in Minnesota
- Work on public projects
- Purely administrative or overhead services
- Machinery repair unrelated to improving the property
- Waste removal or cleanup services not tied to construction
Before filing a lien in Minnesota, make sure you’ve met any preliminary notice requirements that apply to your role (see table above).
Deadline to File
All claimants must file a Statement of Lien Claim within 120 days after the last furnishing of labor, materials, skill, or machinery.
Filing Requirements
- Filing location: County recorder where the property is located; registrar of titles in the county where the property is located for registered land; Secretary of State for railway and line construction.
- Form requirements: The Statement of Lien Claim form must include:
- Notice of intent to claim and hold a lien
- Lien amount claimed
- Description of labor, materials, or services provided
- Name of the person or entity the claimant contracted with
- First and last dates of furnishing
- Legal or reasonably identifiable property description
- Name of the owner (to the best of the claimant’s knowledge)
- Claimant’s name and mailing address
- Statement confirming the required preliminary notice was given, if applicable
- Verification: The lien statement must be signed under oath by someone with knowledge of the facts, as well as notarized.
- Filing fee: Varies by county recorder.
Service Requirements
A copy of the recorded lien statement must be personally served or sent by certified mail to the property owner, the owner’s authorized agent, or the party who contracted with the claimant within 120 days after the last furnishing of labor or materials (Minn. Stat. § 514.08, subd. 1).
Recording a lien preserves your rights—but enforcement is how you get paid. Here’s what you must do to ensure you enforce your lien in Minnesota.
Enforcement Procedures
- Enforcement deadline: A foreclosure action must be filed within one year after the last furnishing of labor or materials listed in the lien statement.
- Additional filing: A notice of lis pendens must be recorded at the start of the enforcement action to preserve priority against later buyers or lenders.
- Filing location: Minnesota District Court in the county where the property is located.
- Lien priority: Lien priority generally relates back to the first visible improvement on the project. When multiple liens exist, valid lienholders share the sale of the proceeds proportionally rather than by filing order.
Lien Release Requirements
Once the lien is paid, bonded off, or otherwise satisfied, the lien claimant should record a written satisfaction or release in the same office where the lien was recorded to clear title to the property.
- Unified workflow: Manage lien rights within your billing and collections workflow to keep payment context in one place.
- Automated compliance: Automatically track critical deadlines and milestones based on each state's lien laws.
- Meaningful visibility: View the lien protection status for each project to identify and mitigate risk.
- Document creation: Generate state-specific lien notices instantly using existing project data
- Integrated delivery: Send notices via certified mail directly from Siteline to streamline delivery.
Minnesota lien statutes do not expressly condition lien rights on licensing. However, performing work without a required license can create serious enforcement problems and defenses in court. Therefore, license compliance is strongly recommended.
Yes. Subcontractors, suppliers, and laborers can file mechanic’s liens in Minnesota, provided the required notices were sent and the statutory deadlines are met.
No. Minnesota’s lien deadlines are set by statute and cannot be shortened by contract or owner filings.
No. Minnesota does not require a notice of intent to lien before recording a mechanic’s lien.
In most cases, yes.
- General contractors must include a statutory notice in their written contract with the owner or deliver it separately within 10 days after the work is agreed upon.
- Subcontractors, suppliers, and laborers must deliver a written notice to the owner within 45 days after first furnishing labor or materials.
Failing to send these required notices can eliminate lien rights entirely (Minn. Stat. § 514.011).
This preliminary notice requirement doesn’t apply to specific cases of commercial projects or residential spaces with more than four units.
There are no specific lien waiver forms to fill out in Minnesota. Clearly state the amount being waived and the applicable property for work performed. For more information, review our Minnesota lien waiver guide here.
Lien amounts depend on your role and notice compliance. Direct contractors may lien for the unpaid contract price. Others may be limited by the unpaid balance owed by the owner at the time notice is received.
Liens may include labor, materials, and qualifying machinery or equipment furnished for the improvement, but generally exclude attorney’s fees—though these, along with interest, can be awarded by the court to the prevailing party.
No. Minnesota law explicitly states that lien rights can arise from written, oral, or implied contracts. That said, written contracts make it far easier to prove scope, timing, and amounts owed if a lien is challenged.
