“Post no bills” is a legal notice telling the public that no one may attach flyers, posters, stickers, banners, or other materials to the surface without the owner’s permission. The word “bills” is an older term for public notices or advertisements, and the prohibition carries real legal weight: violating it can bring municipal fines, civil liability for cleanup, and in some cases criminal charges for vandalism or criminal mischief.
What the Notice Actually Prohibits
The scope is broader than paper flyers. Stickers, banners, wheat-paste posters, and spray-painted promotions all fall within the reach of most anti-posting laws. Some ordinances go further and cover chalk markings, decals, and any material affixed to a surface without authorization.
“Posting” covers nearly any method of attachment. Gluing, taping, nailing, stapling, and painting all qualify. The point isn’t the technique but the result: something was placed on a surface by someone with no right to put it there. Even temporary methods like tape or magnets can violate the rule if the owner or local law prohibits the activity.
Who Enforces It
Enforcement depends on who owns the surface, and the answer shapes both the process and the penalties.
On Private Property
A private owner has broad authority to prohibit any posting. The “post no bills” sign functions as explicit notice that unauthorized materials are unwelcome, which strengthens the owner’s position in any later trespass or property damage claim. Building managers, construction companies, and business owners can remove unauthorized materials immediately and pursue the person responsible.
On Public Property
On utility poles, bridges, lampposts, and government buildings, the rules come from municipal ordinances and sometimes federal law. Federal law specifically prohibits displaying signs, placards, or advertisements on certain federal property, including the grounds of the Supreme Court Building.1Office of the Law Revision Counsel. 40 USC 6132 – Sale of Articles, Signs, and Solicitation in Supreme Court Building and Grounds Cities and counties maintain their own ordinances covering public infrastructure, and enforcement typically falls to code enforcement officers, sanitation departments, or police.
Fines, Civil Liability, and Criminal Charges
The penalties for ignoring the notice generally fall into three categories. Which one applies depends on where the posting happened, how much damage it caused, and whether the violator has done it before.
Municipal Fines
Most unauthorized posting is treated as a code violation carrying a fine. First-offense fines in many cities start in the range of $75 to $250, and repeat violations within the same year can push the penalty significantly higher. Some jurisdictions impose escalating fines designed to deter serial offenders, and the total can multiply quickly when dozens of flyers are posted in one night. Courts often add the actual cost of removing the materials on top of the base fine.
Civil Liability for Damage and Cleanup
Property owners can pursue civil claims for trespass, property damage, and restitution of cleanup costs. Removing wheat-paste posters, paint, or adhesive residue from stone, brick, or glass is often expensive, and the owner is entitled to recover those costs. When the posting causes lasting damage, the owner may also seek compensation for diminished value or the cost of full restoration.
Criminal Charges
When unauthorized posting causes significant property damage, prosecutors can bring criminal charges. Vandalism and criminal mischief statutes in most states cover defacing or damaging another person’s property, and spray-painting, heavy adhesive posting, or repeated large-scale flyering campaigns can meet that threshold. These charges are typically misdemeanors but can be elevated to felonies when the dollar amount of damage is high enough. Repeat offenders and organized commercial flyering operations have faced jail time in the most serious cases.
The Business Being Advertised Can Be Liable Too
A common misconception is that only the person who physically sticks a poster to a wall faces consequences. In practice, the business being advertised is often the primary enforcement target. Many municipal ordinances reach anyone who directs, authorizes, or benefits from illegal posting, not just the person with the glue bucket.
If a restaurant hires a marketing firm to distribute flyers and that firm plasters them on buildings and utility poles, both the firm and the restaurant can face fines. Some jurisdictions set higher minimum fines for the person who directed the posting than for the person who carried it out. The “I didn’t know they’d post illegally” defense rarely works when the entire point of the contract was street-level advertising.
Where the Rule Doesn’t Reach
“Post no bills” is not an absolute rule. Several categories of expression are protected against government enforcement, and one category is protected against employer enforcement. These exceptions matter because they’re easy to miss.
Signs on Your Own Home
The Supreme Court has held that local governments cannot enforce a blanket ban on signs displayed on residential property. In City of Ladue v. Gilleo, the Court struck down an ordinance that prohibited nearly all residential signs, recognizing that displaying a sign from your own home is a uniquely important form of personal expression. If you own or rent the property, a government-imposed restriction generally cannot stop you from displaying political signs, protest messages, or similar noncommercial speech on your own walls, windows, or yard. Governments also generally cannot require permits or charge fees for signs on private residential property, since those function as prior restraints on speech.2Justia Law. City of Ladue v Gilleo, 512 US 43 (1994)
Ordinances That Pick and Choose by Message
In Reed v. Town of Gilbert, the Supreme Court established that sign ordinances treating different categories of signs differently based on their content are subject to strict scrutiny, the toughest standard in constitutional law.3Justia Law. Reed v Town of Gilbert, 576 US 155 (2015) An ordinance that allows “for sale” signs but prohibits political signs, or imposes stricter size limits on ideological signs than on directional signs, is content-based and almost certainly unconstitutional. Cities cannot pick which messages are acceptable through their sign regulations.
Union Literature in the Workplace
Under Section 7 of the National Labor Relations Act, employees have the right to engage in collective organizing activities, which includes distributing union literature in the workplace.4National Labor Relations Board. National Labor Relations Act An employer can enforce reasonable, non-discriminatory rules about when and where this happens, but cannot impose a blanket ban. Employees may distribute literature during non-work time in non-work areas such as break rooms and parking lots. An employer who tolerates birthday announcements and takeout menus on a break room bulletin board but singles out union materials is engaging in discriminatory enforcement, which violates federal law.5National Labor Relations Board.

Two Boundaries Worth Flagging
These protections apply only against government enforcement, not private property owners. A building owner who posts a “post no bills” notice on their own facade has every right to remove your political poster from it. And homeowners’ associations sit in a gray area: because they are private entities, they can impose sign restrictions that a government could not, including outright bans on yard signs or limits on size and duration. Whether those restrictions are enforceable depends on the HOA’s governing documents and state law, not the First Amendment.
