Alaska Trespassing Laws: Degrees, Defenses, and Use of Force

Alaska trespassing laws split the offense into two degrees. Second-degree criminal trespass is a Class B misdemeanor with up to 90 days in jail and a $2,000 fine. First-degree criminal trespass, which covers entering a dwelling or entering land with intent to commit a crime, is a Class A misdemeanor carrying up to one year in jail and a $25,000 fine.¹² A distinctive feature of Alaska law is a default privilege to enter unimproved, apparently unused land, which reflects the reality of a state where most acreage has no fences, signs, or visible boundaries.

What Counts as Unlawful Entry

Alaska’s trespass statutes are built around the idea of entering or remaining somewhere “unlawfully.” Three situations qualify. You enter or stay on premises or in a vehicle that isn’t open to the public and you have no privilege or permission to be there. You are in a place open to the public but the person in charge personally tells you to leave and you refuse. Or you enter or stay on premises or in a vehicle in violation of a protective order issued under Alaska’s domestic violence statutes.³

That third category is worth flagging. If a court has issued a protective order barring you from a specific location, entering that property counts as unlawful entry under the trespass statute itself. You do not need a separate charge for violating the protective order.

The Privilege to Enter Unimproved Land

Because so much Alaska land has no fences or signs, the law grants a default privilege to enter unimproved, apparently unused land, provided you have no intent to commit a crime there and the land isn’t fenced or enclosed in a way meant to keep people out.³

The privilege ends in one of two ways. The landowner or an authorized person can revoke it by telling you directly that you are not welcome. Or the owner can post no-trespassing signs in a manner that is reasonably conspicuous under the circumstances. Once notice is given by either method, staying on the land is no longer privileged. What counts as adequate posting depends on the property; a small sign hidden in brush along a remote river is not the same as a sign at the edge of a suburban lot.

Second-Degree Criminal Trespass

The baseline offense is criminal trespass in the second degree. You commit it by entering or remaining unlawfully on any premises or in any propelled vehicle. Premises includes buildings, structures, and land. Propelled vehicle includes cars, boats, planes, and snowmachines.⁴

It’s a Class B misdemeanor, with a maximum of 90 days in jail and a fine up to $2,000.¹² This is the charge that fits the most common scenarios: walking into a closed business after hours, refusing to leave a store when asked, or entering someone’s fenced yard without permission.

First-Degree Criminal Trespass

First-degree criminal trespass applies in two situations: you enter or remain unlawfully on land with intent to commit a crime there, or you enter or remain unlawfully in a dwelling.⁵

A dwelling is a building or structure where someone lives or sleeps. Breaking into a garage or warehouse alone does not trigger first-degree trespass. Entering a home, cabin, or occupied camper does, even without theft or harm. The intrusion into a living space is treated as inherently more serious.

The intent-to-commit-a-crime element applies to any land, not just structures. Crossing onto private property planning to steal equipment, damage a pipeline, or poach game elevates the offense regardless of whether you actually carry out the underlying crime.

First-degree criminal trespass is a Class A misdemeanor, punishable by up to one year in jail and a fine up to $25,000.¹²

Defenses to a Trespass Charge

Emergency Use of Premises

Alaska has a specific statutory defense for emergencies. If you entered, used, or occupied premises because of an immediate and dire need, you have an affirmative defense. There is a condition that trips people up: you must contact the property owner, the owner’s agent, or the nearest police agency as soon as reasonably practical, and report when you entered and any damage caused. Skip that step and the defense is gone.⁶

The defense exists partly because of Alaska’s conditions. Taking shelter in an unlocked cabin during a blizzard, or entering a fish camp to treat hypothermia, are the scenarios the legislature had in mind. Property owners can waive the reporting requirement by posting a notice, which is common at remote structures.

Reasonable Belief in Consent

Because the statutes hinge on entering “unlawfully,” a genuine belief that you had permission can defeat the charge. If a landowner told you months ago that you could cross their property to reach a trailhead, and you didn’t know that permission had been revoked, your reasonable belief in continuing consent undercuts the state’s case. This isn’t a separate statutory defense; it’s a failure to prove the entry was unlawful.

Necessity

Alaska courts also recognize a broader necessity defense. You must show you acted to prevent a significant harm, that no adequate alternative existed, and that the harm caused by trespassing was not disproportionate to the harm avoided.⁷ It is harder to establish than the emergency-use defense because it requires balancing harms rather than simply proving dire need.

When a Property Owner Can Use Force

Alaska law lets a property owner, or anyone in possession or control of premises, use nondeadly force when they reasonably believe it is necessary to stop a criminal trespass of any degree. There is no duty to retreat from your own property before using reasonable force to remove a trespasser.⁸

Deadly force is different. You may only use deadly force on your premises to stop what you reasonably believe is a burglary in an occupied dwelling or building. A trespasser who is simply on your land, even one who refuses to leave, does not create a justification for deadly force. The line between trespassing and burglary is the line between nondeadly and deadly force under Alaska law.⁸

Civil Liability for Trespassing

Criminal charges aren’t the only exposure. A property owner can sue a trespasser in civil court for damages. Even when a trespass causes no measurable harm, courts recognize a legal injury from the violation of the right to exclude others, and may award nominal damages as a symbolic amount acknowledging the intrusion.

When trespass causes actual harm, compensatory damages cover the real cost: damaged crops, tire ruts across a field, a broken gate, contaminated water. If the trespass was intentional and outrageous, punitive damages can be added on top of compensatory or nominal damages. Courts have found that knowingly entering property without consent or privilege can show enough disregard for the owner’s rights to justify punitive damages even when physical damage is minimal.

Owners dealing with repeat trespassers can also seek a court injunction ordering the trespasser to stay off the property. Violating an injunction carries contempt-of-court penalties, which gives the order more weight than a no-trespassing sign.

The statute of limitations for a civil trespass action on real property in Alaska is six years from the date of the trespass.⁹
