Texas Trespassing Laws: Notice, Penalties, and Defenses

Texas trespassing laws on private property are set out in Penal Code Section 30.05, which makes it a crime to enter or remain on another person’s land without permission once you’ve been given notice that entry is forbidden.¹ Depending on where the trespass happens and what the person is doing, the penalty runs from a $500 fine up to a third-degree felony. Owners also have statutory authority to use force, and in narrow situations deadly force, to end a trespass in progress.

What Makes Entry a Crime

Three things have to line up for criminal trespass: a person entered or stayed on property, they did it without the effective consent of the owner, and they either knew entry was forbidden or were asked to leave and didn’t.¹ The statute reaches residential land, agricultural land, buildings, recreational vehicle parks, residential treatment centers, aircraft, and other vehicles.

“Entry” means the intrusion of the entire body. An arm over the fence line is not enough. Once your whole body crosses the boundary without permission, the offense is complete, whether you meant harm or just wandered onto the wrong parcel.¹

Consent has to come from the owner or someone with apparent authority to speak for the owner. A guest at a house party can’t invite you in. And a visit that began lawfully turns criminal the moment the owner or manager tells you to leave and you stay.

How Owners Give You Notice

Everything turns on notice. Texas recognizes five forms, and an owner only has to use one.¹

Oral or written communication from the owner or an authorized representative telling the person not to enter or to leave.
A fence or other enclosure obviously designed to keep people out or hold livestock in. No signs required.
Posted signs placed where someone approaching the property would reasonably see them.
Purple paint marks on trees or posts meeting the statutory specifications.
Visible crops being grown for human consumption that are under cultivation, being harvested, or ready to harvest.

That last one surprises people. A field of ripe corn or tomatoes is itself notice, with no fence and no sign needed.¹

Purple Paint Specifications

Purple paint carries the same legal weight as a “No Trespassing” sign, and it holds up better in rural country where signs get stolen, weathered, or knocked down. The marks have to be exact. Each mark is a vertical line at least eight inches long and at least one inch wide. The bottom of the mark sits no lower than three feet and no higher than five feet off the ground. Marks have to be placed where they are readily visible to anyone approaching the property, no more than 100 feet apart on forested land and no more than 1,000 feet apart on open land.¹ Faded marks that no longer read as clearly purple can undercut notice even if they were compliant when applied.

Penalties by Classification

Texas sorts trespass into four levels based on where it happened and what the person was doing.

Class C Misdemeanor

Entering agricultural land and staying within 100 feet of the property boundary, or entering residential land within 100 feet of a protected freshwater area, is a Class C misdemeanor.¹ The maximum penalty is a $500 fine with no jail time.² Move deeper than 100 feet onto the ag land and the offense climbs to Class B.

Class B Misdemeanor

Standard trespass is a Class B misdemeanor, the default when no aggravating or mitigating factor applies.¹ It carries up to 180 days in jail, a fine up to $2,000, or both.³ Walking onto fenced land or entering a building without permission typically lands here.

Class A Misdemeanor

The charge rises to a Class A misdemeanor, punishable by up to one year in jail, a fine up to $4,000, or both,⁴ when the trespass occurs:

In a habitation or a shelter center
On a Superfund site
On or inside a critical infrastructure facility (which must be completely enclosed by a fence or barrier obviously designed to keep people out)
On property of a residential treatment center
On higher-education property by someone with a prior trespass conviction at a college or university

Carrying a deadly weapon during any trespass also triggers a Class A charge regardless of where it happened.¹

Third-Degree Felony

Trespass becomes a third-degree felony when it occurs in connection with human smuggling under Penal Code Section 20.05(a)(2),¹ exposing a defendant to two to ten years in prison.

Statutory Defenses

Several categories of people have defenses that can defeat a trespass prosecution outright, even when consent was clearly absent.

Firefighters and emergency medical personnel are protected when they enter in the lawful discharge of official duties under emergency circumstances.¹

Utility workers have a defense too. Employees and agents of electric utilities, telecom providers, cable and video service providers, gas utilities, pipeline operators, electric cooperatives, and municipally owned utilities can enter when performing duties within the scope of their employment.¹ A broader catch-all protects anyone who works for an entity that had effective consent, or that the worker reasonably believed had legal authorization to enter. A contracted surveyor working for a utility with an easement is a common example.

Licensed handgun holders get their own carve-out. If the only reason entry was forbidden was a “no firearms” policy, a person carrying a handgun with a valid Texas license has a defense, provided the handgun is concealed or carried in a holster.¹ A related defense protects condominium owners, tenants, and their guests who carry or store firearms in their units or vehicles despite a building-wide firearms prohibition.

Force a Property Owner Can Use

A person in lawful possession of land can use reasonable, non-deadly force when they reasonably believe it is immediately necessary to prevent or end a trespass. That authority comes from Penal Code Section 9.41.⁵ “Immediately necessary” matters. An owner can physically remove someone who refuses to leave, but can’t track the person down the next day and retaliate.

Deadly Force

Texas is one of the few states that allows deadly force to protect property, and the conditions are narrow. Under Section 9.42, deadly force is justified only when the owner reasonably believes it is immediately necessary to prevent arson, burglary, robbery, aggravated robbery, nighttime theft, or nighttime criminal mischief.⁶ It is also justified to stop someone fleeing immediately after burglary, robbery, aggravated robbery, or nighttime theft if they are escaping with the stolen property.

Two further conditions apply every time. The person must first be justified in using non-deadly force under Section 9.41, and they must reasonably believe either that the property cannot be protected any other way or that using lesser force would expose them or someone else to a substantial risk of death or serious bodily injury.⁶ The nighttime qualifier on theft and criminal mischief is where many people go wrong. Someone stealing property in daylight does not, standing alone, justify deadly force under this statute.

Drones Are Treated Separately

Drone surveillance has its own statute. Under Government Code Section 423.003, using a drone to capture images of a person or privately owned property with the intent to conduct surveillance is a Class C misdemeanor.⁷ Intent is the hinge: a drone that incidentally photographs a backyard while flying over a neighborhood is not automatically criminal. Deliberately hovering to monitor someone’s property is.

A person who captures an image in violation of the section has a defense if they destroy the image as soon as they realize the violation occurred and don’t share it with anyone.⁷ Because drones fly in FAA-regulated airspace, property owners generally cannot shoot one down or physically interfere with it. The remedy is law enforcement.

Civil Lawsuits by Owners

Criminal charges are not the only option. A property owner can sue civilly for trespass. If the trespass caused measurable harm, like damaged crops, broken fencing, or contaminated soil, the owner can recover the actual cost of repair or replacement. Even where no physical damage occurred, the owner is typically entitled to nominal damages for the violation of their property rights. A civil suit may also seek an injunction ordering the trespasser to stay off the property permanently, which is especially useful against repeat offenders and encroaching neighbors.

For civil liability purposes, “agricultural land” means land suitable for producing crops, livestock, or forest products,⁸ and it does not have to be actively farmed at the moment. A fallow field or a wooded parcel zoned for timber production still qualifies.
