943.01(1): Criminal Damage to Property in Wisconsin

Under Wisconsin Statute § 943.01(1), criminal damage to property in Wisconsin is a Class A misdemeanor punishable by up to nine months in jail and a fine of up to $10,000 for intentionally damaging someone else’s physical property without consent.¹² The charge jumps to a Class I felony when the damage exceeds $2,500 or touches certain protected categories of property, and a conviction almost always comes with a court-ordered restitution bill on top of any fine.

What the Prosecution Has to Prove

To convict you, the state has to establish three elements beyond a reasonable doubt: you intentionally caused damage, the property belonged to someone else, and the owner did not consent.¹

“Intentionally” matters. The prosecutor has to show you acted with the specific purpose of causing damage. Bumping a shelf and knocking a vase to the floor is not a crime, even if the vase shatters. Picking the vase up and throwing it at the wall is.

Ownership is broader than people assume. Wisconsin courts have held you can be convicted of damaging property you partly own, as long as someone else also has an ownership interest. Smashing a shared television during an argument still counts.

Consent is the last piece, and it has to be real and specific to what you did. A landlord telling you to “make the place your own” has not authorized you to knock out a load-bearing wall. When the parties disagree about what was permitted, a jury decides whether a reasonable person would have understood the consent to cover what actually happened.

Misdemeanor Penalties and Restitution

A Class A misdemeanor conviction under subsection (1) exposes you to up to nine months in county jail, a fine of up to $10,000, or both.² Judges have wide latitude inside those limits. A minor scratch on a car lands differently than spray-painting a storefront, even though both sit under the same statute.

Restitution is separate from the fine and nearly automatic. Wisconsin law requires the court to order restitution in property damage cases unless the judge identifies a substantial reason not to and puts that reason on the record. Break a $3,000 window, get hit with a $2,000 fine, and you still owe the $3,000. The order can require returning the property if possible, or paying the reasonable cost of repair or replacement when return is not practical.³ For property destroyed outright, the court uses the greater of its value at the time of destruction or at the time of sentencing.

One trap worth knowing: restitution extends to “read-in” crimes, meaning charges dismissed as part of a plea deal that the defendant agreed the court could consider at sentencing.³ Plead guilty to one count with two others read in, and you can be ordered to pay for all three.

When the Charge Becomes a Felony

Section 943.01(2) lists circumstances that elevate the same conduct to a Class I felony, carrying up to three years and six months in prison plus a fine of up to $10,000.⁴ The most common trigger is dollar value, but several others apply:

Damage exceeding $2,500, measured as the cost to repair or replace the property, whichever is less.⁵
Damage to a vehicle, highway, bridge, railroad, navigable waterway, or airport when the damage is likely to cause injury or further property damage.⁵
Damage to public utility or common carrier property that could impair services.⁵
Damage to property of a current or former grand or petit juror because of their role in a verdict or indictment.⁵
Damage to property on state-owned land listed on the state’s historic property registry.
Defacing or destroying archaeological rock art sites on the national or state register of historic places.

A separate provision under subsection (2d) also creates felony liability for intentionally damaging plants, seeds, or harvested materials tied to commercial agriculture or plant research conducted with government agencies or universities.¹

How the $2,500 Threshold Gets Calculated

Most charging fights happen at the dollar-value line. The statute measures damage as the cost to repair or replace the property, whichever is lower.⁵ If someone keys a luxury car and the body shop quotes $4,000 to repaint the panel but a used replacement panel costs $1,800 installed, the damage value is $1,800 and the charge stays a misdemeanor.

Prosecutors build the number from repair estimates, invoices, or testimony by the property owner. Defense attorneys counter with competing appraisals. When several items are damaged in a single incident, the statute uses the combined total, so hitting a few cheap items at once can still push you over the felony line.

Defenses That Actually Work

Consent is the cleanest defense. If the owner authorized what you did, there is no crime. This comes up constantly in landlord-tenant disputes, shared property breakups, and roommate situations where verbal permission later gets denied. Documentation changes outcomes. A text saying “go ahead and tear out the old carpet” can mean the difference between a conviction and a dismissal.

Mistake of fact applies when you genuinely and reasonably believed the property was your own. Because subsection (1) requires damage to “property of another,” demolishing something you honestly thought was yours fails that element. The belief has to be reasonable, though. If your neighbor repeatedly told you the fence was theirs, claiming confusion won’t carry you.

Necessity, under Section 939.47, justifies otherwise criminal conduct when natural physical forces caused you to reasonably believe the act was the only way to prevent imminent public disaster, death, or great bodily harm.⁶ Breaking down a neighbor’s door to pull someone from a fire qualifies. Breaking a car window out of frustration does not. The threat must be immediate, the act must be the only available response, and you cannot have caused the emergency yourself.

Wisconsin’s broader privilege statute also provides a defense for conduct in recognized categories of justification, including coercion, defense of persons or property, carrying out the duties of public office, or making a lawful arrest.⁷ A firefighter who breaks through a wall during an emergency response is privileged under the public-duty provision.

Civil Liability on Top of the Criminal Case

A criminal case does not shield you from a civil lawsuit by the property owner. Civil court uses a lower standard of proof, so winning your criminal case does not guarantee you win the civil one, and the owner can sue regardless of whether you were convicted, acquitted, or never charged.

If the owner wins a civil judgment, Wisconsin law gives them collection tools. The judgment can attach as a lien against your real estate, blocking a sale or refinance until it’s paid.⁸ Wages, bank accounts, and personal property are all reachable through standard post-judgment collection.⁹ Between a criminal fine, court-ordered restitution, and a civil judgment, the total financial exposure often dwarfs the original cost of the damage.

Can You Get a Criminal Damage Conviction Expunged

A Class A misdemeanor stays on your record permanently unless the court orders expungement. Under Section 973.015, the judge can order expungement at sentencing if you were under 25 when you committed the offense, the maximum possible sentence is six years or less, and the court finds you will benefit from expungement without harm to society.¹⁰ A Class A misdemeanor’s nine-month maximum clears the six-year cap easily.

The order has to happen at sentencing. If the judge does not include expungement in the original sentence, you cannot come back later and ask for it. You also have to successfully complete your sentence, meaning no new convictions and, if on probation, no revocations and all conditions satisfied, before the supervising authority issues the certificate of discharge that makes expungement take effect.¹⁰ For anyone 25 or older at the time of the offense, expungement is not available under current law.
