Castle Doctrine Law: Washington

In recent years, Washington is a state that has become increasingly known for draconian governmental policies on everything from taxation to land use, and it is no wonder that many defensively minded folks have such a negative opinion of the place.

However, as it turns out Washington has surprisingly solid laws concerning self-defense, and even though not strictly codified as such, it has statutes on the books that are the functional equivalent of the castle doctrine statutes found in other states.

In short, so long as an occupant of a home or other dwelling is attempting to stop the unlawful use of force against themselves or another person by an attacker, or attempting to thwart any felony committed against them or the residents they are occupying then lethal defensive force is justified with no obligation to retreat.

But, a cursory reading of Washington state statutes might not give you that impression at first glance. Read on to learn what you need to know about Washington’s laws concerning self-defense in the home.

The Castle Doctrine and Stand Your Ground Law in Washington State

Fast Facts

  • Washington state law considers homicide justifiable whenever it is committed in defense of self, family, or a third party to prevent the risk of death or great bodily injury or to prevent the commission or imminent commission of a felony.
  • Washington state law does not specify any duty to retreat prior to using force in defense of one’s home or other dwellings.
  • A person who has used justifiable force in self-defense will likely still be tried in a court of law after the fact, and whether or not their actions were reasonable will be considered by a jury.

Overview of Castle Doctrine Law in Washington

For all of its bluster in other regards, Washington state law concerning the use of lethal force in self-defense, what they call justifiable homicide, is quite succinct.

Section 98.16.050 states that homicide is justifiable and self-defense when the person using lethal force does so in defense of themselves, a family member, or a third party in their presence or company when it is reasonably necessary in order to prevent the commission of a felony or to prevent the risk of death or great bodily injury at the hands of the attacker.

The use of lethal force in self-defense is also justifiable to prevent the commission or imminent commission of a felony upon the defender, upon their dwelling, or inside their dwelling or any other place of abode.

Notably, the law does not specify anywhere an obligation to retreat or to attempt retreat prior to using lethal force and self-defense.

However, residents in Washington may still be arrested and tried even in clear-cut cases of self-defense, and a jury will then decide the reasonableness, or lack of reasonableness, on the part of the defender.


No other restrictions.


Whatever else you might think about Washington’s laws, they are quite clear in matters of self-defense in and around the home or other dwelling.

Citizens have the right to defend themselves, their families, and any other occupants against the use or imminent use of unlawful force against themselves or the commission or imminent commission of felonies. There is no duty to retreat specified in Washington law.
