Is door-to-door soliciting legal in Idaho?
Short answer: yes - courts won't let cities ban knocking outright. But “legal” is doing less work than solicitors would like you to think. Idaho law makes pressure sales cancelable, local rules on permits and hours vary, and once you say “leave,” the law is on your side. Here's the whole picture, with citations.
- Soliciting is legal but regulated - mostly by your city, not the state.
- Anything you signed at your door can usually be canceled within 3 business days (state and/or federal law).
- A solicitor who stays after you say “leave” is trespassing - anywhere in Idaho.
- What a posted sign means varies by city: honored in Boise and Meridian as a matter of city rule - the state trespass statute’s posting spec is written for acreage, not for a porch.
What Idaho state law gives you
Three business days to cancel
Idaho’s Home Solicitation Sales part gives the buyer until midnight of the third business day after signing to cancel. Cancellation happens when you give written notice to the seller at the address stated in the agreement.
The agreement has to state your rights
Section 28-43-403 governs the form of the agreement and the required statement of the buyer’s rights. A doorstep contract with no cancellation language is defective on its face - which is worth noticing before you sign rather than after.
Idaho’s posting rule is built for land
Idaho trespass covers entering posted property without permission - but read what “posted” means: “No Trespassing” signs or at least 100 square inches of fluorescent orange paint, spaced no more than 660 feet apart and readable from outside the property.
That is a ranch-and-timber specification. On a suburban lot it is satisfied easily enough by a sign at the entrance, but the enforceable protection most Idahoans actually rely on is their city ordinance - and, everywhere, the instruction to leave.
Your city sets the door-knocking rules
Idaho's largest cities regulate solicitors in different ways - a good preview of how much this varies town to town. If yours isn't here, search "[your city] solicitor permit."
Boise
Boise requires every door-to-door solicitor to be licensed by the city and to carry and display the official license at all times. The license carries the individual’s photograph and the Boise City logo, so it is checkable at a glance.
Soliciting is confined to 9:00 a.m. to 8:00 p.m., and solicitors may not work a property where a “no soliciting” or “no solicitors” sign is present. Registered 501(c)(3) organizations - scouts, school groups, churches - are exempt from the license.
A photo license with a city logo is the easiest credential in the country to sanity-check at a door.
Coeur d’Alene
Coeur d’Alene devotes a standalone chapter of its municipal code (5.72) to door-to-door solicitation rather than folding it into general business licensing, which means there is a specific local rule to cite when something goes wrong.
Ada County
Outside city limits, Ada County issues its own Solicitor and Peddler License through the County Clerk - so a home in the unincorporated county is not outside the licensing system, just under a different office.
What a “No Soliciting” sign does - and where it falls short
Post one. Where the local code gives it legal force it turns some canvassers away, and everywhere it establishes that a knock wasn't welcome. But the patchwork above exposes the sign's two structural weaknesses: the rules protecting you differ block by block, and a sign creates no record of who ignored it. Enforcement is almost always complaint-driven - and a complaint is only as strong as your ability to say who knocked, and when.
Make the sign checkable - and the ignoring of it a record
A do-not-knock list a company can actually be held to is the stronger model. NoKnock is that idea for any address in the country - you register free, put a QR decal at your door, and canvassing organizations that subscribe get a “Do Not Knock” answer for your home before anyone walks up. If someone knocks anyway, logging it takes seconds, so the fourth violation reads as a pattern, not four bad afternoons.
Honest caveat: the registry is young, and not every canvasser checks it yet. The decal works on day one regardless - and it's the only option on this page that turns an ignored “no” into a timestamped record.
Religious and political canvassers play by different rules
In Watchtower v. Village of Stratton (2002), the U.S. Supreme Court held that a town can't require a permit for religious, political, or other noncommercial door-to-door canvassing. That's why city permit schemes carve those groups out, and why a “permit, please” challenge only works on commercial sellers.
What survives for noncommercial visitors: the trespass baseline (they must leave when asked) and, in some cities, posted-sign rules that apply to everyone. If you want maximum legal coverage from a sign alone, “No Trespassing” generally sweeps broader than “No Soliciting.”
Common questions
Is door-to-door soliciting legal in Idaho?
Yes, and the Treasure Valley cities license it. Boise requires a city license carried and displayed at all times, bearing the solicitor's photo and the city logo, and confines soliciting to 9:00 a.m. to 8:00 p.m. Ada County licenses solicitors in unincorporated areas. State law gives you three business days to cancel.
Is ignoring a No Soliciting sign illegal in Idaho?
In Boise, Meridian and Nampa, solicitors are not allowed to work a property displaying a "no soliciting" or "no solicitors" sign. Statewide, Idaho Code § 18-7008 covers posted property, but its posting specification - fluorescent orange marks at intervals up to 660 feet - is written for open land rather than a suburban entrance.
Can I cancel a contract signed with a door-to-door salesperson in Idaho?
Yes. Idaho Code § 28-43-402 gives you until midnight of the third business day after signing, by written notice to the address in the agreement. Section 28-43-403 separately requires the agreement to carry a statement of your rights, so a contract with no cancellation language is defective.
Do charities and scouts need a permit in Idaho?
Generally no. Boise exempts representatives of registered 501(c)(3) organizations - scouts, school groups, churches and charities - from the city solicitor license. Commercial solicitors still need the license and must display it.
