Michigan home improvement contract requirements
Michigan has no single home improvement contract act, but four laws shape the contract a residential builder hands a homeowner: the licensing article of the Occupational Code, section 114 of the Construction Lien Act, the Home Solicitation Sales Act and, when the homeowner pays over time, the Home Improvement Finance Act. Get the first two wrong and you can lose the right to sue or to file a lien.

Licensing comes first
Article 24 of the Occupational Code licenses two kinds of contractor. A residential builder builds, replaces, repairs, alters, adds to, improves or demolishes a residential structure for pay. A residential maintenance and alteration contractor does repair, alteration, addition, improvement or demolition work, builds garages or lays concrete on residential property. A residential structure is a one- or two-family home or a townhouse up to three stories, with its appurtenant facilities. Electricians, plumbing contractors and mechanical contractors are licensed separately under the Skilled Trades Regulation Act.
- No license, no lawsuit. A residential builder or maintenance and alteration contractor can't sue to collect for work that needs a license without alleging and proving they were licensed throughout the work (MCL 339.2412).
- Hand over the whole deal. It's a violation to fail to deliver to the purchaser the entire agreement, including any finance or other charges (MCL 339.2411(2)(h)).
- Other violations include abandoning a job without legal excuse, diverting a project's funds to other uses, departing from plans without the owner's consent, and workmanship that doesn't meet the Michigan Residential Code. Homeowners have 18 months from completion, occupancy or purchase to complain about a maintenance and alteration contract.
The Construction Lien Act statement
Section 114 of the Construction Lien Act is the reason every Michigan residential contract should be in writing. You have no right to a construction lien on an owner's or lessee's interest in a residential structure unless you made the improvement under a written contract with them, and any amendments or additions are in writing too. The contract must also contain a statement, in type no smaller than the body of the contract, saying:
- That a residential builder or residential maintenance and alteration contractor must be licensed under article 24 of the Occupational Code, that an electrician must be licensed under article 7 of the Skilled Trades Regulation Act, a plumbing contractor under article 11, and a mechanical contractor under article 8.
- If you must be licensed to make the improvement, that you are licensed, and your license number.
The statute doesn't fix the wording, so state it plainly near the signatures. Unwritten change orders are the common way contractors lose lien rights on part of a job, so put every change in writing as well.
Home solicitation sales
The Home Solicitation Sales Act covers sales of goods or services over $25 where you solicit in person, by phone or in writing, the solicitation reaches the buyer at home, and they agree there. It excludes sales after negotiations at your fixed business location, sales at that location, and sales made through a printed advertisement in a publication of general circulation. The buyer can cancel until midnight of the third business day, and the agreement must carry this next to their signature:
You, the buyer, may cancel this transaction at any time prior to midnight of the third business day after the date of this transaction. See the attached notice of cancellation form for an explanation of this right. Additionally, the seller is prohibited from having an independent courier service or other third party pick up your payment at your residence before the end of the 3-business-day period in which you can cancel the transaction.
- Bigger type than the contract. The notices must be at least 10-point bold and 2 points larger than the contract text, in the language of your sales presentation.
- The form travels with the buyer's copy: a notice of cancellation in duplicate, attached or printed on the back, with the transaction date and mailing deadline filled in.
- Saturdays don't count. Michigan defines a business day as Monday through Friday, excluding the listed holidays, so the window is longer than the federal rule's.
- Until you comply, the clock doesn't run. The buyer may cancel by any means at any time until you've met these requirements.
- Early work is unpaid work. If you performed services before a cancellation, you're not entitled to compensation for them (MCL 445.115). A buyer's emergency request is a narrow exception.
When the homeowner pays over time
A home improvement installment contract falls under the Home Improvement Finance Act. It must be dated and written, with the printed portion in at least 8-point type, and the words "home improvement installment contract" in 10-point bold at the top or directly above the buyer's signature. It must disclose the cash price, down payment and trade-ins, unpaid balance, insurance charges, official fees, amount financed, finance charge in dollars, the installment schedule and the time sale price. It must also carry this notice in at least 8-point bold:
Notice to buyer: (1) Do not sign this contract before you read it. (2) You are entitled to a completely filled-in copy of this contract. (3) Under the law, you have the right to pay off in advance the full amount due and, under certain conditions, to obtain a partial refund of the finance charge. (4) You may rescind or cancel this contract, not later than 5 p.m. on the business day following the date thereof by giving written notice of rescission to the contractor or his agent at his place of business given in the contract or by mailing the notice or cancellation to the contractor to his place of business given in the contract by depositing a properly addressed certified letter in a United States post office or mail box…
Deliver a completed copy when it's signed: until you do, the buyer isn't obligated to pay (MCL 445.1204).
Signing it electronically
Michigan's Uniform Electronic Transactions Act lets both sides sign electronically (see e-signature law in Michigan), and under it an electronic record satisfies a law that calls for a writing. The home solicitation form is written for paper (attached to the buyer's copy, or on its back), so deliver the PDF with the form pages at once and consider leaving printed copies too. For notices the law requires in writing, get the consumer's consent to electronic records first (15 U.S.C. § 7001(c)).
Setting it up in SignMaster
- 1

- 2
Size the notices before upload

- 3
Sign at the house, collect later
Use Sign in person for the contract. Count three Michigan business days from the date signed before you take payment or start work.
- 4
Write every change down
Send each change as a change order for both signatures, which keeps the amendment in writing as section 114 requires.
General information, not legal advice
This summarizes Michigan Compiled Laws as published by the Legislature in November 2026. Lien rights depend on more than the contract (notices of commencement and furnishing, sworn statements), so ask a Michigan construction attorney about your forms.
Questions? Answers.
Does a Michigan home improvement contract have to be in writing?
To keep construction lien rights on a home, yes: section 114 of the Construction Lien Act requires a written contract, written amendments and the licensing statement. Licensees must also deliver the entire agreement to the purchaser.
Do Saturdays count in Michigan's three-day cancellation period?
No. The Home Solicitation Sales Act defines business days as Monday through Friday, excluding listed holidays such as Memorial Day and Thanksgiving.
Can an unlicensed contractor sue for payment in Michigan?
Not for work that requires a residential builder or maintenance and alteration contractor license. MCL 339.2412 requires the contractor to allege and prove they were licensed during the work.
What changes when the homeowner finances through me?
The Home Improvement Finance Act applies: the contract is titled a home improvement installment contract, carries the notice to buyer, lists the finance disclosures, and can be rescinded until 5 p.m. the next business day.
