How long does a homeowner have to cancel a home improvement contract in South Dakota?

In South Dakota, a buyer in a door-to-door sale of goods or services of $25 or more may cancel before midnight of the third business day after the transaction by mailing or delivering a signed and dated cancellation notice or other written notice, or sending an electronic notice, to the seller. The seller must give the buyer, when the buyer signs, a completed form in duplicate captioned "NOTICE OF CANCELLATION," attached to the contract or receipt and easily detachable, stating that the buyer may cancel without any penalty or obligation within three business days, and must also tell the buyer orally of the right to cancel. Within ten business days after receiving a valid notice of cancellation, the seller must refund all payments, return any goods traded in, and cancel and return any negotiable instrument the buyer signed. A door-to-door contract or receipt may not include a waiver of the right to cancel. The law does not cover a sale where the buyer started the contact for a bona fide immediate personal emergency and gave the seller a separate, dated and signed statement in the buyer’s handwriting describing it and waiving the right to cancel within three business days, or a visit the buyer asked for to repair or maintain the buyer’s personal property, except for additional goods or services sold during that visit. The federal cooling-off rule separately gives three business days to cancel many sales made at the buyer’s home. This is SDCL §§ 37-24-5.1, 37-24-5.2, 37-24-5.3, 37-24-5.4, 37-24-5.5, 37-24-5.6.

How Seayora uses this rule

An estimate on Seayora carries its own terms and contract text, and the customer’s approval is recorded with its date, so the day a cancellation period starts is on file for both the contractor and the homeowner.
