New York does not have a Stand Your Ground law. Before you use deadly force outside your home, the state requires you to retreat if you know you can do so with complete personal safety for yourself and anyone else. Inside your own dwelling, that retreat requirement disappears, provided you did not start the confrontation. Everywhere else, standing your ground when you could have safely walked away can turn a self-defense claim into a criminal case.
The Duty to Retreat Outside the Home
New York Penal Law § 35.15 forbids the use of deadly physical force if you know you can avoid the confrontation by retreating with “complete personal safety” for yourself and others.1New York State Senate. New York Penal Law 35.15 – Justification; Use of Physical Force in Defense of a Person Stand Your Ground states remove that obligation and let a person hold their position anywhere they are legally allowed to be. New York goes the other direction.
In everyday terms, if someone threatens you on the street, in a parking lot, or in any public place, and you have a realistic way to leave, the law expects you to take it. A prosecutor can point to that available exit as proof your use of force was unnecessary. The rule has a built-in limit, though: retreat is only required if you can do it with complete safety. You are not obligated to run into traffic, jump from a balcony, or turn your back on an armed attacker who is close enough to close the distance. If retreating would itself put you or someone else in danger, the duty falls away.
The retreat requirement applies only to deadly force. For ordinary physical force, § 35.15(1) lets you defend yourself or someone else when you reasonably believe force is necessary to stop an imminent use of unlawful force, and you do not have to try to leave first.1New York State Senate. New York Penal Law 35.15 – Justification; Use of Physical Force in Defense of a Person Whatever force you use still has to be proportional to the threat.
The Home Exception
New York’s Castle Doctrine sits inside § 35.15(2)(a). If you are in your own dwelling and you were not the initial aggressor, you do not have to retreat before defending yourself with deadly force.1New York State Senate. New York Penal Law 35.15 – Justification; Use of Physical Force in Defense of a Person You still need a reasonable belief that the other person is using or about to use deadly force against you. What changes is that you are not required to try to escape your own bedroom, kitchen, or living room first.
“Dwelling” has a specific meaning. Penal Law § 140.00 defines it as a building usually occupied by a person for overnight lodging.2New York State Senate. New York Penal Law 140.00 – Criminal Trespass and Burglary; Definitions of Terms A house and an apartment both qualify. A vehicle or watercraft can count if it is used for overnight lodging, so an RV you regularly sleep in may fit, but the car you drive to work almost certainly does not. Shared spaces in an apartment building — hallways, lobbies, stairwells — sit outside the definition because they are not your individually occupied unit.
That narrow definition also means the Castle Doctrine does not stretch to a lot of places people assume it does. It does not cover your car during a road-rage incident, your front yard, your workplace, or a friend’s house. In each of those, the standard duty to retreat applies. New York is more restrictive on this point than states that extend home protections to vehicles and workplaces.
When Deadly Force Is Actually Justified
Two situations authorize deadly force under § 35.15(2). The first is when you reasonably believe the other person is using or about to use deadly physical force against you and you cannot retreat safely, or you are inside your dwelling and did not start the fight.1New York State Senate. New York Penal Law 35.15 – Justification; Use of Physical Force in Defense of a Person
The second is when you reasonably believe the other person is committing or attempting to commit one of a short list of violent felonies:
- Kidnapping
- Forcible rape
- Forcible aggravated sexual abuse
- Robbery
- Burglary, when deadly force is authorized for defense of premises under § 35.203New York State Senate. New York Penal Law 35.20 – Justification; Use of Physical Force in Defense of Premises and in Defense of a Person in the Course of Burglary
That list is exhaustive. If the crime is not on it, this branch of the statute does not authorize deadly force, no matter how serious the situation feels in the moment. Arson, for instance, is not on the list, which surprises people who assume every violent felony qualifies.
When You Cannot Claim Self-Defense
If you started the confrontation, the justification defense generally is not available to you. Section 35.15(1)(b) bars justified force by the initial aggressor, and the home exception in § 35.15(2)(a) is available only to someone who is “not the initial aggressor.”1New York State Senate. New York Penal Law 35.15 – Justification; Use of Physical Force in Defense of a Person
There is one way back. If you genuinely withdraw from the encounter and clearly communicate that withdrawal to the other person, and they keep coming at you with force anyway, the right to defend yourself returns. The withdrawal has to be real and visible. Pausing or taking a step back is unlikely to be enough; the other person needs to understand you are done.
Two other bars apply. You cannot claim justified force if you provoked the confrontation with the specific intent to injure someone, and you cannot claim it in a fight that both people agreed to — what the statute calls “combat by agreement.”1New York State Senate. New York Penal Law 35.15 – Justification; Use of Physical Force in Defense of a Person
How Courts Judge Whether Your Fear Was Reasonable
Almost every self-defense case turns on the phrase “reasonably believes.” The New York Court of Appeals set out a two-part test in People v. Goetz. First, you must have actually and honestly believed force was necessary to protect yourself from an imminent attack. Second, a reasonable person in your situation, knowing what you knew, would have held the same belief.4NYCourts.gov. People v Goetz
Both parts have to be satisfied. Sincere fear is not enough on its own. New York’s standard jury instructions put it plainly: “an honest belief, no matter how genuine or sincere, may yet be unreasonable.”5NYCourts.gov. Justification: Use of Deadly Physical Force in Defense of a Person Penal Law 35.15(2) If you thought the hand going into a pocket was reaching for a weapon, you clear the first prong. If a reasonable person in the same spot would have seen it as someone reaching for a phone, you fail the second.
The circumstances a jury weighs include the physical setting, the time of day, any prior interactions with the other person, and the defendant’s relevant knowledge and experience. Self-defense cases are won and lost in that analysis: the facts that made you feel threatened have to be facts that would make most people feel the same way.
Who Has to Prove What
A point many people misunderstand: self-defense is not an affirmative defense in New York. It is an ordinary defense, and the difference matters. Under Penal Law § 25.00, once you raise justification at trial, the prosecution has to disprove it beyond a reasonable doubt.6New York State Senate. New York Penal Law 25.00 – Defenses; Burden of Proof
You do not have to prove you acted in self-defense. You only have to put enough evidence in front of the jury to raise the issue. From there, the prosecutor must convince the jury beyond a reasonable doubt that your use of force was not justified. The Court of Appeals reinforced this framework in People v. Hernandez, holding that when deadly force is at issue, the prosecution must prove the defendant knew safe retreat was possible.7Law.Cornell.Edu. People v. Hernandez, 2002 NY Int. 75 – Penal Law 35.15(2) Justification Defense Duty to Retreat
What Happens If Your Use of Force Was Not Justified
If the justification defense fails, you face the same charges you would if the attack had been unprovoked. Non-deadly force that causes injury can bring assault charges, ranging from a Class A misdemeanor to a Class B felony carrying up to 25 years, depending on the severity of the harm. Deadly force that was not justified can produce manslaughter or murder charges, and a genuine but unreasonable belief in danger will not save the defense — failing the objective prong of the Goetz test causes the whole justification argument to collapse.
New York also does not give blanket civil immunity to people whose use of force was justified, the way some Stand Your Ground states do. A criminal acquittal on justification grounds is strong evidence in a later civil case, but the injured person or their family can still sue.
