Minnesota Trespass Law: Penalties, Defenses & Record Impact

Under Minnesota’s trespassing laws, most trespass is a misdemeanor punishable by up to 90 days in jail and a fine of up to $1,000. The charge climbs to a gross misdemeanor — up to a year in jail and a $3,000 fine — when the property is a domestic violence or sex trafficking shelter, a critical public service facility such as a utility or pipeline, or a K–12 school entered by a group of three or more people. What you actually face depends on where you were, whether the property was properly posted, and why you were there.

What Counts as Trespassing

Minnesota’s general trespass statute covers several distinct scenarios, and every one of them requires that you acted intentionally. Wandering across an unmarked property line, or genuinely believing you had permission, does not meet the legal threshold.¹

The conduct the statute reaches includes:

Staying on someone’s property after the owner or lawful occupant tells you to leave.
Entering a dwelling, a locked building, or a posted building without the owner’s consent, absent a genuine emergency.
Returning to property within a year of being told to stay away, with the intent to disturb, threaten, or cause distress.
Being on public or private cemetery grounds during posted closed hours.
Entering someone’s land to take or damage fruit trees, vegetables, or growing crops without permission.
Tampering with monuments or markers that designate property lines or political boundaries.

The statute carves out an explicit exception for emergencies. Entering a dwelling or locked building because someone inside needs immediate help, or because you are fleeing danger, is not criminal trespass.¹

When a Sign Legally Means No Trespassing

A “No Trespassing” sign does not count just because someone nailed it to a tree. Minnesota sets minimum standards, and a sign that falls short may not give the legal notice a prosecutor needs.

Buildings and Dwellings

The sign must be at least 8½ by 11 inches, placed conspicuously on the building’s exterior or somewhere visible on the surrounding property, and carry a general warning against trespass. No specific wording is required, but the message must be clear.¹

Construction Sites

Construction sites have stricter rules because workers and subcontractors may have legitimate reasons to be there. Signs must be at least 8½ by 11 inches and placed conspicuously on the building under construction or within the protected area. For sites under three acres, one additional interior sign is required. For three to ten acres, two additional signs. Beyond ten acres, two more signs for every additional full ten acres.¹

Aggregate Mining Sites

Mining operations must post signs with letters at least two inches high, stating that Minnesota law prohibits trespassing, at intervals of 500 feet or less in conspicuous locations around the site.¹

Standard Misdemeanor Penalties

Most trespass charges land in the misdemeanor tier, which carries a maximum of 90 days in jail and a $1,000 fine.² This covers the everyday scenarios: entering posted property, refusing to leave, going into a locked building, or coming back within a year after being ordered away. A court can add probation, community service, or restitution for damage. Even at this level, the conviction shows up on background checks.

When the Charge Becomes a Gross Misdemeanor

A gross misdemeanor is the next tier up: up to a year in jail and a $3,000 fine.² A few specific situations bump trespass into this tier.

Entering a facility that provides emergency shelter for domestic violence victims, or comparable services for sex trafficking victims, without authorization is a gross misdemeanor. The legislature treated these locations differently because residents are at heightened risk and an uninvited entry can compromise the facility’s security.¹

Trespass on school property also becomes a gross misdemeanor when three or more people enter a public or private K–12 school building together and none of them fits an authorized category. A single unauthorized person on school grounds is a misdemeanor; the group scenario carries the heavier penalty.¹

Trespass on Critical Infrastructure

A separate statute covers trespass on critical public service facilities, utilities, and pipelines. This is where the penalties get genuinely serious, and it is the provision most people do not know about until they have already been charged.

Protected facilities include railroad yards and stations, bus stations, airports, oil refineries, hazardous material storage areas, utilities carrying electric, gas, water, and telecommunications service, and pipelines carrying natural gas, crude oil, or hazardous liquids. Nonpublic portions of bridges are included as well.³

Entering property that contains any of these facilities is a gross misdemeanor if you refuse to leave when asked, if you were told to leave within the past six months and returned, or if the property is posted. Entering an underground structure that houses a utility line or pipeline and is not open to the public is also a gross misdemeanor.³

Hunting and Outdoor Recreation

Minnesota has a dedicated trespass law for outdoor recreation that runs alongside the general statute and applies to hunting, fishing, trapping, boating, hiking, and camping.⁴

You cannot enter agricultural land for any outdoor recreation purpose without first getting permission from the owner, occupant, or lessee. The same rule applies to any land that is posted. Once someone tells you personally to leave and not return, you cannot come back for outdoor recreation for one year.⁵

Verbal permission is usually enough. But if you plan to discharge a firearm within 500 feet of a building occupied by people or livestock on someone else’s private land, you need written permission from the owner, occupant, or lessee.⁵

Penalties for recreational trespass can include fines up to $3,000 and revocation of your hunting or recreational license. Losing a license often stings more than the fine.⁴

School Property Rules

School trespass has its own subdivision and works differently from general trespass. It is a misdemeanor to enter or be found in a public or private K–12 school building unless you are an enrolled student, a parent or guardian of an enrolled student, a school employee, invited by school staff, attending an event open to the public or families, or checked in as a visitor in the manner the school requires.¹

Being on a school building’s roof without permission from a school official is also a misdemeanor. If a principal or designee tells you to leave school property and not return, going back within one year is a misdemeanor even when the building is open for events. The charge becomes a gross misdemeanor when three or more people enter together and none of them qualifies.¹

Defenses That Can Apply

Lack of Intent

Every trespass offense in Minnesota requires intentional conduct. If you wandered onto land because the property line was unmarked or you followed an ambiguous trail, you have a real argument that you lacked the intent the statute demands. This defense comes up often in rural areas where fencing is incomplete. A survey done after the fact can support your account, though it will not help if you ignored a clearly posted sign.¹

Consent

If you had the owner’s permission, you did not trespass. Disputed consent is the harder case: the owner denies it, you insist otherwise. Text messages, emails, witnesses, or a history of prior access can help show a reasonable belief you were welcome. Consent can also be implied, as with a landlord in a common area or a neighbor using a shared driveway openly for years.

Consent can be revoked at any time. Once the owner tells you to leave, the earlier permission no longer protects you.

Emergency

The trespass statute expressly exempts entry into a dwelling or locked building during a genuine emergency. Kicking in a neighbor’s door because you see smoke, or entering a locked building to help someone injured, does not count as trespass.¹

The broader common-law doctrine of private necessity can also apply. Entering property to protect yourself from an immediate threat, such as a violent storm or an attacking animal, can justify the trespass. Private necessity does not wipe out liability for actual property damage, though: no criminal punishment, but you can still owe the owner for what you broke.⁶

Defective Posting

If the case rests on you entering “posted” property, the signs must meet Minnesota’s specifications for that type of property. A faded, undersized, or badly placed sign may fall short, and if it does, the prosecution cannot establish that the property was legally posted. This defense is fact-specific and often comes down to photographs and measurements.

Civil Lawsuits on Top of Charges

Criminal charges are not the only exposure. A property owner can also sue you in civil court, and the two proceedings can run at the same time; one does not block the other.

The bar for a civil trespass claim is lower than for a criminal charge. The owner does not need to prove measurable damage. Even a trespass that leaves no physical trace supports nominal damages, a small court-determined amount that recognizes the violation of the owner’s property rights.⁷

When there is actual damage — torn-up landscaping, broken fences, destroyed crops, contaminated soil — the owner can recover compensatory damages covering repair costs or loss of property value. Courts can also order restitution for the loss of use during the trespass.

Minnesota’s statute of limitations for a civil trespass claim on real property is six years from the date of the trespass.⁸ For ongoing trespass, such as an encroaching structure or repeated crossings, each new intrusion can restart the clock.

What a Conviction Does to Your Record

Even a misdemeanor trespass conviction appears on background checks, and employers routinely run them. EEOC guidance directs employers to weigh the nature and seriousness of the offense, how much time has passed, and how the offense relates to the job before rejecting a candidate.⁹ A blanket ban on anyone with a conviction likely violates anti-discrimination laws, but a trespass conviction can still narrow your options, especially for positions involving property access, security clearances, or work with vulnerable populations.

Minnesota allows people to petition to expunge criminal records, including trespass convictions. Expungement is treated as an extraordinary remedy, and the court applies a clear-and-convincing-evidence standard. You must show that sealing the record benefits you in a way that outweighs any disadvantage to public safety. The court considers how long ago the offense occurred and what you have done since. A hearing cannot be held sooner than 60 days after the petition is served.¹⁰
