If someone is unlawfully entering, or has unlawfully entered, the home or vehicle you occupy, Ohio law presumes you acted in self-defense when you use force intended or likely to cause death or great bodily harm against that person. A prosecutor can rebut that presumption by a preponderance of the evidence. You have no duty to retreat inside your residence before using defensive force.
The presumption protects a person who uses defensive force in the residence or vehicle that person occupies, under R.C. 2901.05(B)(2). It applies to force used in self-defense and to force used in defense of another person. You must be lawfully in the residence or vehicle for the presumption to help you. The person you use force against must not have a right to be there.
The presumption is written for any person who meets these conditions. Its text does not ask whether you carry openly, carry concealed, or carry at all.
Ohio's castle presumption applies only to one level of force. It covers defensive force that is intended or likely to cause death or great bodily harm to another. Force below that level is judged without the presumption.
The presumption protects these places:
The presumption starts when the other person is in either of these situations:
Inside a residence you occupy, the presumption for deadly-level force against an unlawful entrant is rebuttable. It is also subject to limits on who may claim it and against whom.
Retreat is not required either. Under R.C. 2901.09(B), a person has no duty to retreat before using force in self-defense, defense of another, or defense of that person's residence. That rule applies wherever the person lawfully has a right to be, including the person's residence.
The presumption does not apply if either of the following is true:
Even when neither exception applies, the presumption is not final. Under R.C. 2901.05(B)(4), the presumption may be rebutted by a preponderance of the evidence. The prosecution's burden of proof still remains proof beyond a reasonable doubt.
| Rule | Citation | Fact |
|---|---|---|
| Presumed to have acted in self-defense when using deadly-level force against an unlawful entrant into the residence or vehicle you occupy | R.C. 2901.05(B)(2) | |
| Presumption covers only force intended or likely to cause death or great bodily harm | R.C. 2901.05(B)(2) | |
| Presumption is rebuttable by a preponderance of the evidence | R.C. 2901.05(B)(4) | |
| No duty to retreat in your residence or anywhere you lawfully have a right to be | R.C. 2901.09(B) | |
| Trier of fact may not consider the possibility of retreat | R.C. 2901.09(C) | |
| Once evidence tends to support self-defense, prosecution must prove beyond a reasonable doubt that you did not act in self-defense | R.C. 2901.05(B)(1) |
None of the facts we verified for this rule tie the castle presumption to a concealed handgun license or to completed training.
No. A person has no duty to retreat before using force in defense of that person's residence if the person lawfully has a right to be there. Under R.C. 2901.09(C), a trier of fact shall not consider the possibility of retreat when deciding whether your belief that force was necessary was reasonable.
Yes, if you occupy it. The presumption covers the residence or vehicle occupied by the person using the defensive force. The same limits apply in a vehicle, so the presumption does not apply against someone with a right to be in it.
The presumption does not apply if that person is a lawful resident of the residence or has a right to be there. Without the presumption, once evidence tends to support that you acted in self-defense, the prosecution must still prove beyond a reasonable doubt that you did not.
Yes. The presumption is rebuttable by a preponderance of the evidence. Under R.C. 2901.05(B)(1), once evidence at trial tends to support that you used force in self-defense, defense of another, or defense of your residence, the prosecution must prove beyond a reasonable doubt that you did not.
The presumption applies to self-defense and to defense of another person. If there is evidence that you used force in defense of another, the prosecution must prove beyond a reasonable doubt that you did not.
No. The presumption covers only defensive force intended or likely to cause death or great bodily harm. We found no Ohio statute that sets a standard for using force other than deadly force to defend a person, having read Ohio Revised Code 2901.05, the statute that would carry such a rule, on September 23, 2026.
