No Soliciting Sign Law in Idaho: City Rules, Penalties, and Trespass

The no soliciting sign law in Idaho isn’t one law at all. The state has no statute governing door-to-door solicitation, so whether your posted sign carries legal weight depends on the city or county you live in. What is consistent statewide is your underlying property right: once you tell someone to leave, Idaho’s criminal trespass statute applies whether your city has a solicitation ordinance or not. The U.S. Supreme Court has recognized no solicitation signs as a legitimate tool for protecting residential privacy, calling the protection they provide “ample.”¹

Why Your City’s Rules Are the Ones That Matter

Idaho Code Section 18-2001 uses the word “solicitation,” but it’s about encouraging someone to commit a crime, not knocking on doors to sell things.² Because the legislature hasn’t enacted a statewide door-to-door statute, regulation falls to municipalities. Each city writes its own rules on what counts as solicitation, whether solicitors must register, what hours they can work, and what happens when they ignore a posted sign.

The practical result: your protections are only as strong as your city’s ordinance. In an unincorporated area with no county-level rule, your main legal tool is Idaho’s criminal trespass statute, which activates once you tell a solicitor to leave and they refuse.

How a Posted Sign Works in an Idaho City

Coeur d’Alene is a clear example of how municipal enforcement works. Under Ordinance 3505, no person may solicit at any home or business that has clearly posted a sign indicating solicitation or peddling is prohibited.³ That rule applies to every solicitor, registered or not. The ordinance also limits solicitation hours to 9:00 a.m. through 8:00 p.m. and prohibits solicitors from misrepresenting their purpose, their affiliation, or claiming the city endorses their pitch.⁴

Boise regulates door-to-door sales through a licensing chapter for vendors, solicitors, and temporary merchants, and other Idaho cities use similar frameworks. The details vary from city to city, so if you’re on the enforcement side of this question, check your own municipal code for the exact language.

Where a city requires registration, as Coeur d’Alene does, applicants go through a background check and provide information about themselves and what they’re selling.⁵ Providing false information on that application is a separate violation.⁴ Registration also gives you a check at the door: you can ask to see a city-issued permit before continuing any conversation.

What “Clearly Posted” Means

Coeur d’Alene’s ordinance requires that a no soliciting sign be “clearly posted” at the location.³ Idaho municipalities don’t publish exact specifications for size or placement, so the working standard is whether a reasonable person approaching the door would notice the sign. A small sticker on the doorbell can be enough; a weathered sign hidden behind a shrub probably isn’t. Place the sign at your front door or the entrance to your property, keep it legible, and don’t let it get obscured by plants or decorations.

Penalties for Ignoring the Sign

Coeur d’Alene’s three-tier penalty structure shows how the consequences escalate in an Idaho city with an ordinance on the books:

First violation: an infraction with a $100 fine.
Second and third violations: still infractions, but the fine rises to $300.
Fourth and subsequent violations: reclassified as a misdemeanor, punishable by a fine of up to $1,000, up to 180 days in jail, or both.³

The jump from infraction to misdemeanor is the meaningful one. An infraction is a civil penalty. A misdemeanor goes on a criminal record, and for a solicitor working on commission it often costs the job. Enforcement usually starts with a resident’s complaint to police or code enforcement. First-time offenders often receive a warning rather than an immediate citation, but that documented contact is what supports harsher penalties on the next visit.

When Solicitation Becomes Criminal Trespass

This is the part most people miss. Ignoring a posted sign violates a municipal ordinance in cities that have one, but refusing to leave after the property owner tells you to go triggers Idaho Code Section 18-7008, the state’s criminal trespass statute.⁶ Trespass carries heavier consequences than an ordinance violation and applies regardless of whether your city regulates solicitation at all.

The escalation runs like this: a solicitor approaches your door despite a posted sign (an ordinance violation where one applies); you open the door and tell them to leave; if they refuse or come back later, trespass law is in play. For anyone in an unincorporated part of Idaho, that second step is the whole ballgame. Your verbal instruction to leave is what creates the legal violation.

Who Isn’t Bound by Your Sign

Not everyone who knocks is covered by a no soliciting sign. The First Amendment protects political canvassing and religious outreach, and courts have consistently held that municipalities cannot treat these activities the same as commercial solicitation.

The controlling case is Watchtower Bible & Tract Society of New York, Inc. v. Village of Stratton (2002), where the U.S. Supreme Court struck down an ordinance making it a misdemeanor to canvass door-to-door for any advocacy purpose without first registering with the mayor and receiving a permit. The Court found the ordinance violated the right to anonymous speech, burdened people whose religious or political beliefs prevented them from applying for a government license to speak, and effectively banned spontaneous speech on weekends or holidays when permits couldn’t be obtained.¹

An earlier case, Martin v. City of Struthers (1943), struck down a blanket ban on door-to-door handbill distribution, but the Court noted the right approach is “leaving to each householder the full right to decide whether he will receive strangers as visitors.”⁷ That language supports the use of individual no soliciting signs even as it limits what cities can prohibit outright.

The practical point: a Jehovah’s Witness or a campaign volunteer may lawfully approach your door despite your sign, but they are not exempt from a direct request to leave. Once you personally tell them to go, trespass law applies to them like anyone else. The First Amendment protects the right to knock, not the right to stay.

Government workers on official business, such as census takers and building inspectors, aren’t covered by your sign either. Neither are utility workers with easement rights to reach meters or equipment, since their access comes from a legal right attached to the property rather than from your invitation. Some Idaho cities also carve out exemptions for nonprofit or educational canvassing, and those exemptions vary enough between municipalities that a charity welcome in one city may need a permit in the next.

If You Bought Something at the Door

If a solicitor got past your sign and talked you into a purchase, federal law gives you a second chance. The FTC’s Cooling-Off Rule lets you cancel any door-to-door sale of $25 or more within three business days, counting every calendar day except Sunday and federal holidays.⁸

The seller must give you a completed receipt or contract at the time of sale in the language used during the pitch, two copies of a cancellation notice form, and a verbal explanation of your right to cancel. You don’t have to give a reason, and the seller has to refund your money within 10 business days of receiving your cancellation.⁸ If a solicitor pressured you into buying and didn’t hand over these documents, they violated federal law regardless of what happened with your sign.

What to Do When a Solicitor Ignores Your Sign

Handle it in sequence. First, note the person’s name, company, and any permit or badge number they display. That information is what a complaint runs on later. Second, tell them clearly that you have a no soliciting sign posted and ask them to leave. Be direct and calm. You are creating the record that they were put on notice.

If they leave, report the visit to your local police non-emergency line or code enforcement office and pass along what you collected. That documented history is what supports the escalating fines the next time the same solicitor or company appears. If they refuse to leave after you’ve asked, call police and report an active trespass. The situation has moved past a solicitation ordinance into state criminal law.

For repeated problems with a particular company, you can also file a complaint with the Idaho Attorney General’s Consumer Protection Division. The office doesn’t enforce local solicitation ordinances directly, but it investigates patterns of deceptive or aggressive sales practices that cross into consumer fraud.
