Oregon Castle Doctrine: When You Can Use Deadly Force Against an Intruder

By Michael G. Romano, Managing Attorney

Whenever someone in Oregon shoots a home invader or burglar, people argue about whether it was justified. Whether using deadly force was “right” or “wrong” belongs in church or a philosophy class. Whether it was lawful is a different question, and Oregon law answers it more clearly than most people expect. You can use deadly force against someone you reasonably believe is burglarizing your home, and you have no duty to retreat first. There are limits, though, and crossing one can turn a homeowner into a defendant.

Does Oregon Have a Castle Doctrine?

Not by name. “Castle doctrine” is the old idea that your home is your castle, and that you may defend it and the people inside it with force, including deadly force. No Oregon statute uses the phrase. In practice, though, Oregon works like a castle doctrine state. The deadly force statute specifically covers burglary of a dwelling, and the Oregon Supreme Court has held that you have no duty to retreat. Together, those two rules give Oregon homeowners much of what castle doctrine laws give people in other states.

When Oregon Law Allows Deadly Force

The starting point is ORS 161.209. You may use physical force to defend yourself or someone else from what you reasonably believe is the use or imminent use of unlawful physical force, and you may use the degree of force you reasonably believe is necessary. Deadly force has an extra limit. Under ORS 161.219, it’s justified only if you reasonably believe the other person is doing one of three things:

• Committing or attempting a felony involving the use or threatened imminent use of physical force against a person.
• Committing or attempting a burglary in a dwelling.
• Using or about to use unlawful deadly physical force against a person.

The key word throughout is “reasonably.” The question isn’t only what you believed, but whether a reasonable person in your position would have believed it. A jury decides that after the fact, knowing everything the investigation turned up.

What Counts as Burglary in a Dwelling

The second category is the heart of Oregon’s castle doctrine, so the definitions matter. Burglary means entering or remaining unlawfully in a building with the intent to commit a crime inside (ORS 164.215). A dwelling is a building that someone regularly or intermittently sleeps in at night, whether or not anyone is home at the time (ORS 164.205). “Building” is broader than a house. It includes a vehicle, boat, or other structure adapted for overnight stays, so a motorhome or camp trailer you sleep in can qualify.

These definitions decide cases. In State v. Duvall (2014), a man fired at relatives who broke a window to get into his house. The Court of Appeals reversed his convictions because the jury was never told what “burglary” legally means, so it couldn’t fairly decide whether his belief was reasonable.

Your yard, driveway, and detached shop are treated differently. Under ORS 161.225, you may use reasonable physical force to stop a trespasser on your property. Deadly force against a trespasser is justified only in defense of a person under ORS 161.219, or when you reasonably believe it’s necessary to prevent arson or a felony by force and violence.

Do You Have a Duty to Retreat in Oregon?

No. In State v. Sandoval, 342 Or 506 (2007), the Oregon Supreme Court held that Oregon law imposes no duty to retreat before using deadly force. As the court put it, “ORS 161.219 contains no specific reference to ‘retreat’, ‘escape,’ or ‘other means of avoiding’ a deadly confrontation.” That holding applies everywhere you have a right to be, not just at home. Our page on Oregon’s stand your ground rules covers it in more detail.

The Court of Appeals reinforced the point in State v. Cranston (2025). The prosecutor repeatedly suggested the defendant should have walked away, and the trial court refused to tell the jury that Oregon has no duty to retreat. The conviction was reversed. If retreat becomes an issue at your trial, you are entitled to that instruction.

When Self-Defense Doesn’t Apply

ORS 161.215 takes the defense away from people who provoke a fight intending to hurt someone, who start the fight as the initial aggressor (unless they clearly withdraw and the other person keeps coming), or who agree to fight. Beyond those rules, the most common problem in home defense cases is timing. Deadly force is judged by what you reasonably believed when you used it. Once an intruder is fleeing, unarmed and outnumbered, or already subdued, it becomes much harder to show that you reasonably believed deadly force was still justified. Shots fired at someone running away draw the closest scrutiny.

Even a justified shooting will be investigated as a homicide or assault. Expect detectives, a search of your home, and in many cases a grand jury. If you use force to defend yourself, call 911, say you were attacked and need police and medical help, and then stop talking until you have a lawyer. Our guides to self-defense in Oregon and when Oregon law allows the use of force explain the rest of the framework.

Is Oregon a “Make My Day” State?

No. Colorado’s 1985 “make my day” law (C.R.S. 18-1-704.5) gives occupants immunity from both criminal prosecution and civil lawsuits for using force against an intruder in their home. Oregon has no equivalent statute. Being justified under the criminal law doesn’t stop the person you shot, or their family, from suing you.

A recent Portland case shows how that plays out. In 2023, a business owner who lived in the back of his shop shot a man who broke in before dawn. He was never charged, and the intruder was convicted of first-degree burglary. The intruder then sued him for $10 million in Multnomah County Circuit Court. In August 2026, more than three years after the shooting, a jury rejected the claim. The owner won, but only after defending a civil trial over a shooting prosecutors never charged.

Frequently Asked Questions

Does Oregon have a castle doctrine law?

Not by name, but Oregon law works much like one. ORS 161.219 allows deadly force against someone you reasonably believe is committing or attempting a burglary in a dwelling, and the Oregon Supreme Court held in State v. Sandoval (2007) that there is no duty to retreat.

Can I shoot someone breaking into my house in Oregon?

Oregon law allows deadly force if you reasonably believe the person is committing or attempting a burglary in your dwelling, or is about to use deadly force or commit a violent felony against someone. The belief must be reasonable, and the shooting will be investigated. Shooting someone who is fleeing or no longer a threat is far harder to justify.

Do I have to retreat before defending myself in Oregon?

No. Oregon has no duty to retreat, at home or anywhere else you have a right to be. If a prosecutor argues you should have walked away, you are entitled to a jury instruction that Oregon law does not require retreat (State v. Cranston, 2025).

Can I use deadly force against a trespasser in my yard?

Generally no. ORS 161.225 allows reasonable physical force to stop a trespasser, but deadly force only in defense of a person or to prevent arson or a felony by force and violence. A trespasser who threatens no one does not justify deadly force.

Can a burglar sue me in Oregon for shooting them?

Yes. Oregon has no law like Colorado’s “make my day” statute that grants civil immunity. An intruder or their family can file a lawsuit even if you were never charged, though a jury can reject the claim, as one did in a Portland case in 2026.
