Often, yes. Under the FTC's Cooling-Off Rule, a customer who signs a contract worth $25 or more at their own home, or anywhere that is not your normal place of business, gets three business days to cancel for any reason and receive a full refund. If you pitched and signed the job at the customer's kitchen table, they can almost certainly back out within three days. If they came to your office or showroom and signed there, the federal rule usually does not apply. And on top of the federal rule, many states give home-improvement customers their own right to cancel, sometimes for longer. Here is how it works and how to handle a cancellation without losing money.
What the federal 3-day rule actually is
The Cooling-Off Rule is a federal Federal Trade Commission rule. It gives a consumer until midnight of the third business day to cancel certain sales and get all their money back, no reason required. As of 2026 it applies to sales of $25 or more made at the buyer's home, workplace, or dormitory, and to sales of $130 or more made at a seller's temporary location, like a hotel room, convention center, or fairground booth. It exists to protect people from high-pressure, in-your-living-room sales.
The point to burn into memory: this is about where the sale happened, not what the work is. A roof, a remodel, new windows, an HVAC swap, all of it can be covered if the deal was closed at the customer's home.
What triggers it, and what does not
Covered, generally:
- A contract signed at the customer's home or workplace for $25 or more. In-home sales are the classic case.
- A contract signed at a temporary sales spot (a home show, a booth, a hotel presentation) for $130 or more.
Usually not covered:
- A contract the customer signs at your permanent office or showroom. If they came to your place of business, the federal rule generally does not apply.
- Sales made entirely by mail, phone, or online with no salesperson meeting the customer in person.
- Certain categories the rule carves out, like real estate, insurance, and sales under the dollar thresholds.
There is also a genuine-emergency path: if a customer asks you in writing to start an urgent repair right away and waives the cancellation right, that waiver can apply. Get it in writing, and do not lean on it as a routine workaround.
What you are required to give the customer
The rule is not just "they can cancel." As the seller, you are supposed to tell the customer about the right and hand them the tools to use it: notice of their cancellation right and, under the federal rule, two copies of a dated cancellation form, with the deadline filled in. If you skip that, you have a problem, because the cancellation clock may not start, or the customer's window to cancel can stretch well past three days. Do it right and the clock runs cleanly.
The state layer, which is often bigger
The federal three-day rule is the floor, not the ceiling. Many states have their own home-improvement or home-solicitation laws that add a right to cancel, sometimes a longer window, sometimes with extra notice language you must print in the contract, and sometimes with stronger protections for older customers. Some states also require specific cancellation wording in every residential home-improvement contract regardless of where it was signed. These vary widely and change, so the exact window, the exact notice language, and who it covers all route to Working in Your State. Never assume the federal three days is the whole story.
What to do when a customer cancels in time
- Stop work and stop ordering. If they cancel within the window, the deal is off and they are owed their money back.
- Refund promptly. Under the federal rule you generally must return the customer's money within 10 days of a valid cancellation.
- Handle materials by the rule. The cancellation rules cover what happens to any goods already delivered; follow them rather than improvising.
- Keep it professional. A customer who cancels cleanly today may hire you later, or refer you, if you did not make it a fight.
How to protect yourself
The whole risk of the three-day rule is spending money on a job that then evaporates. So:
- Do not order custom materials or start irreversible work until the cancellation window has closed, unless you have a proper written emergency waiver.
- Include the required cancellation notice in your contract and give the customer their copies at signing. This both complies with the rule and starts the clock.
- Where you can, sign at your office or showroom, which usually takes the sale out of the federal in-home rule, though your state's own home-improvement rules may still apply.
- Write your deposit and start-date terms with the window in mind, so an early cancellation does not leave you out of pocket for materials you cannot return.
Common questions
Does the 3-day rule apply if the customer signed at my office?
Usually not. The federal Cooling-Off Rule is triggered by sales made at the customer's home, workplace, or a temporary sales location, not at your permanent place of business. So a contract the customer came in and signed at your office or showroom generally is not covered by the federal three-day right. Be careful though: your state may have its own home-improvement cancellation law that applies regardless of where it was signed. Check Working in Your State before you assume the customer has no way out.
Do I have to refund the deposit if a customer cancels in three days?
Yes. A valid cancellation within the window means the customer is owed a full refund, and under the federal rule you generally have to return their money within 10 days. That includes the deposit. This is exactly why you should not spend that deposit on non-returnable materials or start irreversible work until the cancellation window closes. Your state's home-improvement law may also cap deposits or set its own refund timing, so confirm the specifics in Working in Your State.
What if I already started the work when they cancel?
If the cancellation is valid and you started without a proper written emergency waiver, you are exposed, because the customer can still cancel and you may be owed nothing for work done in that window. That is the core reason not to begin irreversible work or order custom materials until the three days pass, unless the customer signed a genuine written waiver for an urgent repair. Handle any materials already delivered under the cancellation rules rather than improvising. For a disputed situation with real money at stake, talk to a construction attorney.
Is the federal 3 days the only cancellation right?
No. The federal three-day rule is the minimum, and many states add their own, sometimes longer, right to cancel a home-improvement contract, plus required notice wording. Some states also protect older customers more strongly or require cancellation language in every residential contract. These vary a lot and change, so treat the federal three days as the floor and get your state's actual window and required notices from Working in Your State before you write your contract.
The honest bit
- The federal figures here (the three-business-day window, the $25 in-home and $130 temporary-location thresholds, the 10-day refund period, and the notice requirements) reflect the FTC Cooling-Off Rule as of 2026. Verify the current rule at ftc.gov before you rely on it.
- State home-improvement cancellation windows, required contract notices, deposit limits, and extra protections vary by state and are often broader than the federal rule. Get yours from Working in Your State.
- This is general guidance, not legal advice. If a cancellation dispute involves real money or you are unsure whether a job is covered, ask a construction attorney.
