What a Wisconsin Remodeling Contract Must Include
Many remodeling disputes start the same way: a homeowner signed something vague, work began, and then money, scope, or a missed date turned into an argument with nothing in writing to settle it. Wisconsin's home improvement rule, Chapter ATCP 110, requires many of these terms in writing. A solid contract in 2026 spells out 8 things before you sign.

Remodel project - T&JThis article is general information, not legal advice. If you are unsure about your specific contract, the Wisconsin Consumer Protection Bureau (1-800-422-7128) or a local attorney can review it with you.
The 8 Things Your Wisconsin Remodeling Contract Must Spell Out
Here is the checklist, in the order it should appear in the contract you are about to sign:
Scope of work, with products and materials named
Total price, plus a payment schedule tied to finished work
Start and completion dates
Written change orders, including product substitutions
Permits: which are required, and who pulls them
Insurance and credentials, in writing
Warranty terms, in writing
Lien waivers and final-payment terms
Miss any one of these and you are the one holding the risk. A vague scope lets a low bid look competitive when it is really thinner. No payment schedule means guessing when the next check is due and for what. No change-order clause is how a small add-on turns into an argument over an invoice you never agreed to.
Wisconsin regulates part of this, not just best practice. Under ATCP 110.05, a home improvement contract must be in writing, along with every later change to it, if it requires you to pay anything before the work is finished, or if the seller started the sale through door-to-door, mail or phone solicitation. Since most remodels involve a deposit, that covers nearly every project. A written contract is also not just good hygiene. It has to be signed by all parties, and you must get a copy before work starts or any payment is taken.
Scope, Specs, and Materials: What "Complete" Looks Like
A complete scope of work names the actual work and the actual products. The state rule says the contract has to describe the work to be done and the principal products and materials, including where applicable the name, make, size, capacity and model of principal products or fixtures, and the type, grade, quality, size or quantity of principal building materials. It also has to list the name and address of the seller.
Compare two ways of writing the same line. One says "install cabinets." The other names the cabinet line, the number and size of the boxes, the door style, the hardware, and whether labor is included. Both might land close in price, but only one tells you what you are buying.

John walks your space, measures it, and leaves a written itemized estimate. No cost, no obligation, no sales script.
That gap is a big reason quotes differ more than homeowners expect. A low bid is often not a better price. It is a thinner scope behind a smaller number, and the missing detail comes back later as a change order. If you are comparing bids right now, our guide on why kitchen remodel quotes come out so different shows what to look for line by line.
When you compare bids, ask each contractor the same three questions:
- What brand and model is this line item?
- Is this price labor only, or labor plus material?
- What do the sub-trade costs cover, and whose crew does that work?
If a contractor cannot answer cleanly, that is a gap in the scope, not a gap in your understanding.
Ask for the cabinet, flooring and fixture spec sheets to be attached to the contract, not just referenced by name. A brand name without a model number still leaves room to swap in a cheaper item mid-project.
Put the day-to-day terms in writing too: who handles daily cleanup, how floors and furnishings are protected, and what hours the crew works. The law does not require these, but they are exactly what gets argued about when they are left as a verbal assumption.
Price and Payment Schedule: Tying Money to Milestones
The rule requires the contract to state the total price, including any finance charges. If the job is time and materials, it has to state the hourly labor rate and every other term that affects price.
A payment schedule goes one step beyond the legal minimum, and it is what protects your cash. Tie each payment to a stage of work you can see and verify, such as demolition complete, rough-in passed inspection, cabinets installed, and a finished walkthrough, not to calendar dates. A contract that only says a deposit now and the balance at the end is a guess dressed up as a schedule.
Wisconsin also bars a seller from asking you to sign a completion slip or make final payment before the work is finished under the contract (ATCP 110.02(6)(e)).
How big a deposit should be, and what to do if a contractor takes one and disappears, have their own coverage. See our guide on what deposit a Wisconsin remodeling contractor should ask for and our post on what to do when a contractor took your deposit and never finished. Read both before you sign.
Start and Completion Dates, and Why Blank Ones Are a Red Flag
A written home improvement contract must set out the dates or time period on or within which the seller will begin and finish the work (ATCP 110.05(2)(d)). It is a required term, not boilerplate a contractor can skip.
If a contractor hands you a contract with the start date blank, or a completion date that says "TBD," that is a gap the rule does not allow. For a homeowner, a blank date field can mean the crew has not been scheduled, or that the contractor does not want to commit to a timeline.
If a contractor says they will fill in the dates later, once the job gets going, do not sign yet. Once your signature is on the page, you have agreed to whatever is written there, blanks included.
Delays are covered too. If the work will run past a deadline in your contract, the seller has to give you timely notice with the reasons and new proposed dates, and a new deadline only takes effect if you agree to it in writing (ATCP 110.027). The exceptions are delays you caused, acts of nature such as a tornado, flood or fire, and civil disorder. A contractor who is organized enough to run a real schedule can give you a start window and a finish window up front, even if both carry some flexibility for weather or material lead times.
Change Orders: How Scope Changes Get Priced and Approved
A change order is a written document that describes a change to the original scope, states the price impact, and is signed by you before the new work starts. Under ATCP 110.05, changes to the terms of a written contract must themselves be in writing, and a verbal okay during a walkthrough is where most mid-project price disputes begin.
Substitutions are covered separately. A seller cannot swap in different products or materials than the ones in your contract without your consent, and when the contract is written, that consent has to be in writing (ATCP 110.023). The rule allows a verbal go-ahead only for a change that adds no cost to you and lowers no value, and then only if the seller documents when and how you approved it and reports it to you before taking final payment.
Remodel - T&JThink about what often comes up once a wall is open in an older home: corroded supply lines, rot, outdated wiring. A good change order describes what changed, states the added cost, and gets signed before the trade touches it. No signature, no new charge. That is also the cleanest answer to a question many homeowners eventually ask: why did the price balloon mid-project? Usually it traces back to verbal adjustments that added up. For the bigger picture, see our post on why remodels go over budget in Wisconsin.
Wisconsin Statute 100.20(5) lets a person who suffers a monetary loss because of a violation of ATCP 110 sue the seller directly. The statute allows recovery of twice the loss, plus costs and reasonable attorney fees.
Permits: Which Ones Are Required, and Who Pulls Them
Your contract should say in writing which permits the project needs and who is responsible for pulling them. The rule backs this up. Before you sign, the seller has to inform you of all building or construction permits required for the job, and the seller cannot start work until the required state and local permits have been issued (ATCP 110.03). Where inspections are required, copies of the inspection certificates must be given to you when the work is finished and before final payment is due.
Permit requirements depend on the project and on your local building department. Wisconsin's Uniform Dwelling Code sets the statewide baseline for one- and two-family homes, but local rules and enforcement vary, so ask your building department. If the contract is silent on who pulls permits, you can find out the hard way, after an inspection fails or a home sale stalls over work that was never permitted. Our post on what happens if work is done without a permit covers that scenario, and our guide to what a homeowner can do without a permit in Wisconsin covers the other side.
Insurance and Credentials: Proof You Should See Before You Sign
If a contractor tells you they are licensed, bonded or insured, the rule requires a written statement describing exactly what type of license, bond or insurance they hold (ATCP 110.02(4)(d)). When a contractor promises insurance protection, the contract has to state its terms, and you are entitled to a copy of the policy declarations page or other proof of coverage before final payment is due.
In practice, ask for a certificate of liability insurance that names your project or address, not just a policy number. Ask which Wisconsin credential the contractor holds, too. The Department of Safety and Professional Services (DSPS) issues the Dwelling Contractor Qualifier credential, which is held by an individual, so you can confirm what a credential means before you sign. A contractor who produces proof without hesitation is telling you something. One who cannot is telling you something too.
Warranty Terms in Writing
A warranty is only as good as what is written down. Under ATCP 110.04, a seller has to give you a copy of every written warranty, and has to put any oral warranty in writing. Any warranty has to be clear and specific about its conditions and exclusions, any limits on scope or duration, and how quickly the seller will act on a valid claim. The contract itself has to include a statement of any warranty on products, materials, labor or services.
A verbal assurance that someone will come back if anything goes wrong means little once the final payment clears. For a real-world example of the standard to hold paperwork to, T&J provides a written 2-year warranty on its remodeling work. Whatever length a contractor offers, ask to see it in writing before you sign.
Remodel - T&JWisconsin's home improvement rule lists the contract terms that must be set out clearly and legibly, including the work, the price, the dates, and any warranty. See ATCP 110.05(2).
Lien Waivers and Final Payment: Closing Out the Job Cleanly
A lien waiver is a signed document in which a contractor, subcontractor or supplier confirms they have been paid and gives up the right to file a lien against your property for that work. You can pay your general contractor in full, in good faith, and still face a claim from a subcontractor or supplier who was never paid downstream. A waiver protects you from that.
Wisconsin builds this protection into the rule. Before you sign, the seller must give you a separate written notice, in the exact wording the rule sets out, that you may request lien waivers. If you ask, the seller must provide written lien waivers from all contractors, subcontractors and material suppliers for the value of the work and materials furnished as of each payment. Unless you say your request covers only the final payment, that means with each partial payment as well (ATCP 110.025).
So put it in your contract, and ask each contractor on your list how they handle lien waivers at each payment and at project close. A contractor with a clean, consistent answer has done this before. One who seems unsure has not thought about what happens after the final check clears.
Cancellation Rights When the Sale Starts at Your Door
If a contractor approached you by face-to-face solicitation away from their regular place of business, or by mail or phone solicitation aimed at you, and you signed away from their office, Wisconsin's consumer approval transaction rules may give you a right to cancel. The home improvement rule points to Chapter 423 of the Wisconsin Statutes for those transactions. Whether and how it applies depends on where and how your contract was signed, so confirm the details for your situation with the Consumer Protection Bureau before relying on it.
Separately, if you paid in advance and the seller misses a deadline in the contract or fails to give required notice of a delay, you can cancel and demand your unspent payments back, plus an accounting of what was spent. You make that demand by written notice, delivered in person or by mail, and the seller has 15 calendar days to return the payments (ATCP 110.07). If a contractor pressures you to start immediately, before you have had time to read any of this, treat it as a red flag.
Refuse to Sign If: The Red-Flag Checklist
Walk away from a contract, or send it back for revision, if you see any of these:
- Blank spaces anywhere: price, dates, or scope left open to be filled in later
- Verbal-only promises that never made it onto the page
- Pressure to pay most of the price upfront, before meaningful work has started
- No written scope of work, just a one-line job description
- No mention of a change-order process anywhere in the document
- No written statement of the license, bond or insurance the contractor claims
- No mention of which permits the job needs and who pulls them
- A warranty promised out loud but not written down
Remodel - T&JWisconsin law gives you real leverage here. A person who suffers a monetary loss because of a violation of ATCP 110 can sue the seller and recover twice the amount of the loss, plus costs and reasonable attorney fees, under Statute 100.20(5). This is not legal advice, and your situation may call for a conversation with the Consumer Protection Bureau or an attorney before you act. But it is worth knowing the leverage exists before you sign something with blanks in it.

Frequently asked questions
Is a verbal agreement enough for a remodeling project in Wisconsin?
For most remodels, no. Wisconsin's home improvement rule requires a written contract, and written changes to it, when the contract calls for any payment before the work is finished, or when the seller started the sale through door-to-door, mail or phone solicitation ATCP 110.05. Even where a verbal deal exists, you would have little to point to if your memory of what was agreed differs from the contractor's, and that mismatch is behind many scope disputes.
What happens if my contractor wants to change the price mid-project?
It should happen only through a written change order that you sign before the new work starts. The change order should describe what is changing, what it costs, and why. Because changes to a written contract have to be in writing, a contractor charging more without that paperwork has skipped a step the rule expects.
Can I get my money back if a contractor does not put things in writing or misses the deadline?
Possibly. If you paid in advance and the seller misses a contract deadline, or fails to give notice of a delay, ATCP 110.07 lets you cancel, demand return of payments not yet spent, and request an accounting, by written notice. More broadly, Statute 100.20(5) allows recovery of twice a monetary loss caused by a violation of ATCP 110, plus costs and reasonable attorney fees. These are serious remedies, so talk to the Consumer Protection Bureau or an attorney about your situation instead of treating any outcome as guaranteed.
Who is responsible for pulling permits, me or the contractor?
The contract should name who, in writing. The rule requires the seller to tell you before you sign about all permits the job needs, and bars the seller from starting work until the required permits are issued ATCP 110.03. Permit rules differ by local building department, so do not assume. For the permitting basics, see our guide to what a homeowner can do without a permit in Wisconsin.
What is the difference between a deposit and a payment schedule?
A deposit is money paid before work starts. A payment schedule ties the remaining payments to finished milestones, like rough-in complete or cabinets installed. The two work together: a reasonable deposit to secure your spot, then payments that follow visible progress. For how much is typical in Wisconsin, see our guide to remodeling contractor deposits.
Do I need a lawyer to review my remodeling contract?
For a smaller single-room project, a careful read against a checklist like this one may be enough. For a larger whole-home project, or anything with an unusual payment structure, a short attorney review is inexpensive protection against a much bigger headache later. This article is general information, not a substitute for legal advice on your specific contract.
What proof of insurance should a contractor give me before I sign?
Ask for a certificate of liability insurance that names your project or address, and ask which Wisconsin credentials the contractor holds. If a contractor says they are licensed, bonded or insured, the rule requires a written statement describing exactly what type ATCP 110.02(4)(d). A contractor who hesitates or cannot produce this on request is a signal to keep comparing bids.
