The contractor's guide to the FTC 3-day right to cancel

July 2026 · 8 min read · Plain-language guidance, not legal advice.

Here’s a fact that surprises most trade contractors: when you sell work in a customer’s home, federal law very often gives that customer three business days to cancel — and requires you to tell them so, in writing, with a cancellation form they can send back. Most contractors have never once done this. The obligation exists anyway.

This guide explains the rule in plain language: when it applies, what you must hand over, what happens if you don’t, and how emergencies are handled.

This is education, not legal advice. State rules layer on top of the federal floor and vary a lot — when in doubt, ask a lawyer licensed in your state.

What the rule is

The FTC’s Cooling-Off Rule (16 CFR Part 429) covers what the regulation calls “door-to-door sales” — a misleading name. It isn’t about uninvited salesmen. It covers sales made anywhere other than your permanent place of business, and the customer’s kitchen table is the textbook example. If the sale happens at the buyer’s home and the purchase is $25 or more, the rule presumptively applies.

Read that again with contractor eyes: a water heater replacement quoted and approved in the hallway, a repipe sold in the living room, a panel upgrade agreed to in the garage — these are in scope. It does not matter that the customer called you and invited you over. An invitation to quote is not an exemption from the rule.

What you’re required to do

When a covered sale happens, you must:

Tell the buyer orally about their right to cancel at the time of sale.
Give them a dated receipt or contract that shows your business name and address and includes a conspicuous notice of the right to cancel, in the same language the sale was conducted in.
Give them two copies of a “Notice of Cancellation” form — one to keep, one they can mail back — stating the date, the deadline (midnight of the third business day), and where to send it.

If the customer cancels in time, you must refund their money within 10 business days and arrange to deal with any goods delivered.

The part that should get your attention

If you never gave the required notice, the three-day clock never starts. The customer’s right to cancel doesn’t quietly expire — it can hang over the transaction indefinitely. A customer (or their lawyer, or a state attorney general) can raise it long after the job is done. The FTC can also seek civil penalties, and home improvement is explicitly on the FTC’s radar under its penalty-offense program.

States pile on from there. Many states have their own home-solicitation and home-improvement contract statutes that are stricter than the federal floor — California’s contractor-specific rules (Business & Professions Code 7159), for example, were amended for 2026 to require the contractor’s email address on the cancellation notice and to give buyers 65 and older a five-day window. If you work in home improvement, your state almost certainly has opinions about your paperwork.

What about emergencies?

This is the exemption contractors actually need to know. The rule provides a path for bona fide immediate personal emergencies: if the customer initiated the contact and genuinely needs the work done now — the burst pipe, the dead furnace in January — they can waive the right to cancel. But the waiver has rules of its own: it must be a personal, handwritten and signed statement from the buyer describing the emergency and expressly waiving the right. A pre-printed checkbox on your standard contract is exactly what that requirement exists to prevent.

Get the waiver right and you can lawfully start emergency work immediately. Fake it routinely and you’ve built a paper trail of violations.

How to comply without slowing down the job

The rule sounds heavy. In practice, compliance is a workflow problem:

Detect which sales are covered (in-home sale, $25+, not a true buyer-initiated emergency).
Deliver the notice and the cancellation form with the signed estimate — same moment, same channel.
Track the window, so nobody starts $9,000 of demolition on day two of a cancelable sale.
Handle cancellations cleanly — refund, unwind, keep the record.
Do emergencies properly — a real waiver, only on real emergencies.

Paper can do this. A three-ring binder of cancellation forms in every truck, and the discipline to use them on every covered sale, forever. Some shops manage it. Most don’t — not from bad intent, but because nothing in their tooling reminds them.

How FieldLane handles it

FieldLane is, as far as we can tell, the first field service platform that treats this rule as a product feature rather than the customer’s problem. When an estimate is approved in a covered situation, the system detects it, sends the right-to-cancel notice automatically — by text and email, with the cancellation form as a PDF — tracks the window on the job, and (if you enable enforce mode) blocks work from starting inside it. Emergencies get a proper customer-signed waiver flow, allowed only on genuine emergency work. Cancellations, if they happen, revoke the approval on the record and everything reconciles.

You didn’t get into the trades to run a compliance program. That’s the point of making it automatic. See how the compliance layer works →
