What Michigan law actually gives you
Michigan doesn't rely on a single consumer protection statute for contractor disputes. It gives homeowners three overlapping legal frameworks, and a well-drafted demand letter uses all of them.
The Residential Builder Act (Mich. Comp. Laws § 570.1101 et seq.) is the foundation. It requires anyone engaged in residential building work to hold a license issued by the Michigan Department of Licensing and Regulatory Affairs. It also requires a written contract, disclosure of the contractor's license number, and a one-year warranty on workmanship and materials. Under Mich. Comp. Laws § 570.1131, a homeowner who prevails in a civil action against a builder for Act violations can recover actual damages, statutory damages up to $5,000, and reasonable attorney's fees.
The Michigan Consumer Protection Act (Mich. Comp. Laws § 445.903) operates alongside the Residential Builder Act. Home improvement work is a consumer transaction, which means contractors who use unfair, unconscionable, or deceptive methods are exposed to MCPA liability. Mich. Comp. Laws § 445.911 allows recovery of actual damages, costs, and attorney's fees, and authorizes the court to award up to three times actual damages when the violation was knowing or willful.
The Home Improvement Finance Act (Mich. Comp. Laws § 570.351) adds a third layer for projects involving financing. It requires pre-contract disclosures, a written contract with all terms, price, payment schedule, and timeline. Failure to comply is itself grounds for civil action.
These statutes don't cancel each other out. Michigan courts allow homeowners to pursue claims under all three simultaneously, which multiplies both the exposure the contractor faces and the credibility of your demand letter.
The unlicensed contractor: your strongest leverage
If your contractor was not licensed when the work was performed, Michigan law hands you a significant advantage. Mich. Comp. Laws § 570.1101(3) provides that an unlicensed contractor cannot enforce a contract for payment for residential building services. That means if you haven't paid in full, you may owe nothing. If you already paid, the contractor's inability to enforce the contract cuts strongly in favor of your recovery claim.
This is not a minor procedural defense. Michigan courts have applied it to dismiss contractor payment claims outright. For a homeowner pursuing a demand letter, citing § 570.1101 and documenting that the contractor does not appear in the LARA license database changes the entire tone of the negotiation. You aren't just disputing quality. You are pointing out that the contractor had no legal right to collect payment at all.
Verify license status before you draft the letter. The Michigan Department of Licensing and Regulatory Affairs maintains a searchable database at michigan.gov/lara. Screenshot the search result with the contractor's name and company. If they aren't in the database, attach that screenshot to your demand letter. Courts and contractors both take unlicensed-operation findings seriously.
Even if the contractor is licensed, the Act still requires a written contract and the one-year workmanship warranty under Mich. Comp. Laws § 570.1105. A contractor who started a job without a written contract, or who refuses to honor warranty obligations, is in violation regardless of license status.
How long you have to act
The clock starts the day the cause of action arises, which is generally the date the breach became apparent, not the date the contract was signed or the work began. In most contractor disputes, that is either the date the contractor abandoned the job, the date defective work was discovered, or the date a promised repair was refused.
For written contracts, Mich. Comp. Laws § 600.2506 sets a six-year statute of limitations. Most home improvement agreements are written (or should be), so six years is the standard window for breach of contract claims.
For oral contracts and implied warranty claims under Mich. Comp. Laws § 600.2507, the period drops to four years. If your contractor was hired with a handshake and no written agreement, four years from the breach date is your deadline.
Six years sounds long. Four years moves faster than people expect, especially when disputes involve seasonal work, delayed discovery of defects, or extended back-and-forth negotiations. Don't treat the window as an invitation to wait. A demand letter sent within weeks of the problem carries more weight, practically and legally, than one sent years later when memories and records have faded.
What you can recover
Your recoverable damages fall into several categories, and the total can be meaningfully larger than whatever you paid the contractor.
Actual damages. The cost to have another licensed contractor complete or repair the work. This is your baseline. Get a written estimate from a licensed Michigan contractor before you draft the letter. That estimate is your anchor number.
Statutory damages. Under Mich. Comp. Laws § 570.1131, you can claim up to $5,000 in statutory damages without proving a specific dollar loss beyond actual damages. This is especially useful when the defect is real but hard to price precisely, such as incomplete framing, improperly installed plumbing, or substandard materials substituted for what was specified.
Treble damages. If the contractor's conduct was knowing or willful under the MCPA (Mich. Comp. Laws § 445.911), the court can award up to three times your actual damages. Patterns that support a willful finding include taking a large deposit and disappearing, substituting inferior materials while billing for premium ones, performing work without permits when permits were required, or repeatedly misrepresenting the status of the job.
Attorney's fees. Both the Residential Builder Act and the MCPA authorize recovery of reasonable attorney's fees from a losing contractor. This matters even in a demand letter context because it signals that if this escalates to litigation, the contractor faces their own attorney's fees plus yours.
Refund of deposit or overpayment. Any amount paid above the value of work actually and properly performed.
The combined exposure, actual damages plus $5,000 in statutory damages plus potential treble damages, is why a demand letter that cites all of Michigan's applicable statutes is taken seriously. The contractor's attorney, if they have one, can do that math.
Evidence you'll need before you send the letter
A demand letter is only as strong as the paper behind it. Gather the following before you draft:
The contract. Every page of the written agreement, signed by both parties. If there is no written contract, document the oral terms in a contemporaneous memo and note the date you're writing it.
Proof of payment. Bank statements, canceled checks, credit card records, wire transfer confirmations. If you paid in cash, a written receipt the contractor provided, or the bank withdrawal records correlated to work start dates.
License verification screenshot. A dated screenshot from the LARA contractor database showing whether or not your contractor appears. If they don't appear, note the exact search terms used.
Photographs. Date-stamped photos of every defect, every unfinished area, and every location where work was performed. Shoot wide angles to establish context, then close-up on each specific problem. Take these before any remediation attempts.
Written repair estimates. At least one written estimate from a licensed Michigan contractor to complete or repair the work. Two estimates are better. These establish your actual damages number.
Permit documentation. If permits were required and not pulled, contact your local building department and request confirmation in writing. An unpermitted project is a code violation, a disclosure problem for the homeowner on future sale, and additional evidence of contractor misconduct.
Correspondence. Every text, email, voicemail transcript, and written communication with the contractor. If the contractor promised to return and didn't, a text thread showing those promises and the subsequent silence is valuable evidence.
Any warranty documents. If the contractor provided a written warranty (required for licensed builders under Mich. Comp. Laws § 570.1105), and is now refusing to honor it, bring the document itself.
Writing the Michigan contractor demand letter
Michigan contractor demand letters are more statute-dense than most other demand letters. That's a feature. When a contractor sees Mich. Comp. Laws § 570.1131, § 445.911, and § 570.351 cited in the first two paragraphs, they understand you've done the homework. That alone shifts the conversation.
Here is what the letter must include:
Opening statement of facts. The contractor's name and license number (or a note that LARA shows no license for them). The property address. A summary of the contract terms: what was agreed, what was paid, and the start and completion dates specified.
Statement of breach. What the contractor failed to do. Be specific. "Failed to complete the kitchen remodel specified in the contract dated [date], having abandoned the project after completing approximately 40% of the scope" is better than "did not finish the job." One fact per sentence.
Statute citations. Cite all applicable statutes in the body. At minimum: Mich. Comp. Laws § 570.1105 (if a written contract or warranty was required but absent), § 570.1131 (statutory damages), § 445.903 (MCPA unfair or deceptive practice), § 445.911 (treble damages for willful violations). If unlicensed operation applies, lead with § 570.1101.
The demand. A specific dollar amount and a deadline of 10 to 14 calendar days from receipt. State that the amount represents actual damages to complete or repair the work, plus the applicable statutory amounts.
The consequence. A clear, factual statement that if payment is not received by the deadline, you will file a civil action in Michigan District Court or Circuit Court (depending on the amount), seeking actual damages, statutory damages, treble damages where applicable, and attorney's fees under both the Residential Builder Act and the MCPA.
Keep it to one page. A two-page demand letter does not carry more legal weight. It signals disorganization. Short, statute-specific, and direct.
If the demand letter doesn't resolve it
When the deadline passes and the contractor still hasn't responded, file a Michigan small claims case against a contractor as your next step. Michigan District Court's small claims division handles claims up to $7,000, which covers most deposit-and-abandonment disputes and many completion disputes.
For claims above $7,000 (which your actual damages plus statutory penalties may well reach once treble damages are in play), filing in Circuit Court is the appropriate route. The demand letter you already sent is evidence in either filing, and judges give credit to plaintiffs who put the contractor on proper written notice before going to court.
What happens after the letter goes out
The letter is mailed via USPS Certified Mail and tracking begins immediately. Most responses arrive within the first week. Here is how the timeline typically plays out:
Days 1 to 3. The contractor receives the letter. Many call or text before it even arrives, having recognized the certified mail notice from the post office. This is not unusual; contractors in active disputes often know a formal letter is coming.
Days 4 to 10. If the contractor intends to respond at all, you'll usually hear within this window. Responses fall into three categories: a settlement offer (often 60 to 80 cents on the dollar), a denial, or silence.
Day 10 to 14 (your deadline). If no payment and no credible settlement discussion, you move to the next step. Do not extend the deadline voluntarily unless you have a specific written counter-offer in hand and a signed payment agreement being prepared.
After the deadline. File the small claims or Circuit Court action. Attach the demand letter and the USPS Certified Mail delivery confirmation as exhibit one. Courts across Michigan treat a documented demand letter as a good-faith prerequisite to litigation, and its presence in the file strengthens your credibility from the moment the case is called.
Roughly 85% of demand letters in residential contractor disputes produce a response or payment before a court filing. The combination of Michigan's statutory damage exposure, the attorney's fees risk, and the unlicensed-operation defense (where applicable) makes most contractors calculate that paying is cheaper than fighting.
