Minnesota Supreme Court Narrows Contractors' Lien Rights in Construction Defect Disputes: What You Need to Know
Sustainable 9, LLC v. Coleman, decided by the Minnesota Supreme Court on August 5, 2026, changes how mechanic's liens interact with construction defect claims. Every Minnesota contractor who forecloses on a lien should understand how this ruling may impact their dispute before it gets to trial.
North Star Law represented the contractor in this case. The Court of Appeals had ruled for the contractor, and the Supreme Court reversed that decision. We think the outcome carries lessons every contractor client should hear directly, in plain terms, regardless of how the case came out for our client.
The short version
If a homeowner proves that a contractor's negligent work caused damage equal to or greater than the value of the contractor's mechanic's lien, the homeowner's defense of recoupment doesn't just reduce what the contractor can collect. It eliminates the lien entirely. And because Minnesota's mechanic's lien statute only awards attorney fees and costs to a contractor who actually prevails on the lien, a contractor who loses the lien this way also loses the fee award that normally comes with a successful lien enforcement action.
What happened in the case
The contractor built a home in Medina, a Minnesota suburb west of Minneapolis and a payment dispute arose near the end of the project over alleged defects. The contractor filed a mechanic's lien and sued to enforce it. The homeowner counter-sued for breach of contract and negligence.
At trial, a jury:
Awarded the contractor roughly $95,000 on its breach of contract claim (the basis for its lien), and
Awarded the homeowner roughly $279,000 on her negligence claim, for damage caused by the contractor's own defective work.
The district court treated these as two separate awards to be set off against each other, found the contractor still had a valid $95,000 lien, and awarded the contractor about $62,500 in attorney fees and costs for successfully enforcing that lien. The Court of Appeals agreed.
The Supreme Court reversed. It held that offsetting two competing awards is legally different from applying recoupment as a defense, and that the homeowner should have been allowed to assert recoupment to defeat the lien outright, not merely reduce it in a final tally.
Why "recoupment" and "setoff" are not the same thing, and why it matters
This is the technical heart of the decision, and it's the piece most likely to catch contractors and even some practitioners off guard.
Setoff nets two independently valid claims against each other at the end of a case. Both claims survive; the numbers are just netted.
Recoupment is an affirmative defense. If it applies, it can defeat the plaintiff's claim outright, the same way proof of payment would, because it's evaluated as part of whether the claim succeeded in the first place, not as bookkeeping after the fact.
The Court held that the district court's approach (award the lien, then just offset it against the negligence damages) was not the same as applying recoupment, and that recoupment should have been evaluated first, as an affirmative defense to the lien claim itself.
The lien and the defect claim don't need a contract link
The contractor argued that recoupment should only apply when the defect claim ties back to specific priced items in the contract. The Court rejected that. It held that a mechanic's lien and a negligence claim can each exist independently of any contract, and that both claims here arose from the same underlying transaction: the construction project itself. That was enough to make recoupment available, regardless of whether the negligence claim mapped onto specific contract line items.
Practical translation: contractors should not assume that framing a defect claim as negligence, rather than breach of contract, insulates the lien from being challenged.
This point deserves emphasis. Both the contractor and the homeowner asked the Court to focus on the construction contract as the relevant transaction, disagreeing only about whether the negligence claim was tied closely enough to specific contract terms. The Court took neither party's approach. It found that inquiry unnecessary altogether, explaining that because the claims arose from the construction project itself, separate from whether an enforceable contract existed, the project was the relevant transaction. The Court described this as a "more straightforward" approach than tying each claim back to the contract. The practical effect is that a defect-based challenge to a lien does not need to be pled or proven as connected to specific contract terms. It only needs to be connected to the same construction project.
Why this matters for Minnesota contractors going forward
Attorney fee exposure is now asymmetric in defect-heavy cases. Pursuing full lien enforcement fees when a homeowner has a serious, well-documented defect claim is a higher-stakes bet than it used to be. If the defect damages equal or exceed the lien amount, the contractor may lose both the lien and the fee argument.
Documentation of workmanship is now lien-critical, not just liability-critical. Records showing the quality of work performed, responses to homeowner complaints, and any homeowner interference with repair access are relevant not only to defending a negligence claim, but to preserving the lien and the fee-shifting benefit that comes with it.
Early resolution of defect disputes has more value than before. Because a large, credible defect claim can wipe out a lien completely, not just offset it, there's more reason to resolve legitimate defect concerns before a dispute hardens into competing trial claims.
This is not a blanket rule against all liens with defect counterclaims. Recoupment only eliminates the lien when damages are large enough to equal or exceed the lien value. Smaller, partial defect claims still function as an offset, not a complete bar. Every case still turns on the size of the numbers a jury (or arbitrator) actually finds.
A new leading case
Minnesota has allowed recoupment as a defense to mechanic's liens for decades, most notably in Knutson v. Lasher (1945), where landowners facing a contractor's lien were permitted to recoup damages for the contractor's faulty performance. Sustainable 9 doesn't disturb that precedent. It confirms it and extends it squarely into the negligence context. This is now the controlling Minnesota authority on how recoupment operates against a mechanic's lien, and contractors and their counsel should expect it to be the first case cited in any future dispute where a defect claim threatens lien value.
Bottom Line
Minnesota contractors should treat outstanding, unresolved defect allegations as a direct threat to lien value and fee recovery, not a separate track that gets settled later. Before filing or aggressively enforcing a mechanic's lien where defect complaints are on the table, it's worth a conversation with counsel about exposure on both sides of the ledger.
