Castle Doctrine States: Defending Your Home (2026)

The castle doctrine is the principle that you have no duty to retreat from your own home before using force against an intruder — your home is your "castle." Effectively all 50 states recognize some version of it. What varies is how far that protection extends — to your car, your workplace, into public — and the roughly 13 states that still require retreat once you step outside the home.

The short version

• Castle doctrine means no duty to retreat in your own home before using force against an intruder.
• All 50 states recognize some form of it at home.
• States differ on whether it also covers your vehicle or workplace.
• About 13 states still require retreat in public — that's the stand-your-ground dividing line.

What is the castle doctrine?

The castle doctrine comes from the old idea that "a man's home is his castle." Legally, it means that when you're inside your own home and face an unlawful intruder you reasonably believe threatens serious harm, you are not required to retreat before using force — including, in most states, deadly force.

It's the most universally accepted piece of American self-defense law.

Which states have a castle doctrine?

All of them, in practice. Every state recognizes that you don't have to flee your own home before defending yourself. The differences are at the edges:

• Some states extend "no duty to retreat" to your vehicle (e.g., Wisconsin).
• Some extend it to your workplace (e.g., Connecticut, Delaware, Hawaii, Nebraska, North Dakota).
• A subset extend it everywhere you're legally allowed to be — that's stand your ground.

Does it cover your car or workplace?

This is the most practical question, and the answer is "it depends on your state." Castle doctrine started with the dwelling, but many states have expanded the "castle" to include:

• Your occupied vehicle — treated like a mini-castle in many states.
• Your workplace — covered in some states, not others.
• Curtilage — the area immediately around the home (porch, yard) in some states.

Some states also add a presumption of reasonableness: if someone unlawfully and forcibly enters your home, the law presumes you reasonably feared harm, shifting the burden to the prosecution. Whether and how far these extensions apply is exactly what separates a strong castle-doctrine state from a narrow one.

States with a duty to retreat

The real dividing line is what happens outside the home. These states still require you to retreat in public when you can safely do so, even though they protect you at home:

Everywhere else, there's generally no duty to retreat in public either. So the practical question for most people isn't "does my state have castle doctrine?" (almost certainly yes) but "does it extend beyond my home?"

Castle doctrine vs stand your ground

It's worth stating the relationship plainly, because the terms are constantly confused:

• Castle doctrine = no duty to retreat at home (universal).
• Stand your ground = no duty to retreat anywhere you're lawfully present (about 29 states by statute).
• Duty to retreat = you must retreat in public if safe, but still not at home (about 13 states).

So every state gives you castle-doctrine protection at home; states then split on whether that protection follows you out the door.

Know your state's limits

Castle doctrine is broad, but it isn't unlimited. Common conditions across states:

• The intruder must be unlawfully entering or present.
• You must reasonably believe force is necessary to prevent serious harm.
• Protections can be weaker against another lawful occupant of the same home.
• Some states require the entry to be forcible or unexpected.
