Washington does not have a statutory "castle doctrine" and does not have a statutory "stand your ground" law. There is no RCW section by either name. Self-defense in Washington is governed by the general use-of-force statutes in Chapter 9A.16 RCW, as interpreted by Washington courts. The "no duty to retreat" rule that people associate with stand-your-ground laws exists in Washington, but it comes from case law, not from a statute.
This section explains the actual legal framework so you can understand it accurately rather than relying on labels that do not apply in Washington.
Washington's self-defense rules live in two main statutes:
The definition of "deadly force" is set out separately in RCW 9A.16.010(2): the intentional application of force through the use of firearms or any other means reasonably likely to cause death or serious physical injury.
RCW 9A.16.020 lists the situations in which the use, attempt, or offer to use force toward another person is not unlawful. The provision most relevant to private self-defense is subsection (3):
Whenever used by a party about to be injured, or by another lawfully aiding him or her, in preventing or attempting to prevent an offense against his or her person, or a malicious trespass, or other malicious interference with real or personal property lawfully in his or her possession, in case the force is not more than is necessary.
The key limit in that text is "in case the force is not more than is necessary." Washington law ties the amount of force to what is necessary, and RCW 9A.16.010(1) defines "necessary" to mean that no reasonably effective alternative to the use of force appeared to exist and that the amount of force used was reasonable to effect the lawful purpose intended.
Other subsections of RCW 9A.16.020 cover force by public officers, citizen arrest after a felony, reasonable detention of a trespasser, force by a common carrier expelling a passenger, and force used to restrain a person who is mentally ill, mentally incompetent, or mentally disabled from committing a dangerous act. Those are situational and are not the general self-defense rule for a permit holder.
When deadly force results in death, the controlling statute for a private citizen is RCW 9A.16.050. It states that homicide is justifiable when committed either:
Subsection (2) is the closest thing Washington has to a "castle" provision. It allows justifiable use of deadly force to actually resist an attempt to commit a felony upon the person, or upon or in a dwelling or other place of abode in which the person is. It is narrower than a true castle-doctrine statute: it is tied to resisting an attempted felony, and the general standard of necessity and reasonableness still applies. There is no statutory presumption of reasonableness for force used inside the home, and no statutory civil or criminal immunity of the kind found in true castle-doctrine states.
Separately, RCW 9A.16.030 provides that a homicide is excusable when committed by accident or misfortune in doing a lawful act by lawful means, without criminal negligence and without unlawful intent. This is distinct from justifiable self-defense and applies to accidents, not deliberate defensive force.
Washington recognizes that a person who is assaulted in a place where he or she has a right to be, and who is not the aggressor, has no duty to retreat before using lawful force in self-defense. This rule is established by the Washington Supreme Court, not by any RCW section.
Because this rule comes from court decisions interpreting RCW 9A.16.020 and RCW 9A.16.050, it can be refined by future cases. Do not expect to find a statute titled "stand your ground" in Washington, because none exists. The protection is real but is grounded in case law applying the general use-of-force statutes.
Whether force is justified in Washington turns on reasonableness and necessity judged from the standpoint of a reasonably prudent person in the same situation. Washington jury instructions evaluate the defender's actions based on the conditions as they reasonably appeared at the time, not on hindsight. The practical points for a permit holder:
RCW 9A.16.110 provides that no person in Washington shall be placed in legal jeopardy for protecting, by any reasonable means necessary, himself or herself, his or her family, or his or her real or personal property, or for coming to the aid of another who is in imminent danger of, or the victim of, a violent crime as defined in RCW 9.94A.030. If a person charged with one of the listed crimes is found not guilty by reason of self-defense, the statute directs the state to reimburse reasonable costs of the defense, including lost time and legal fees, once the trier of fact finds the self-defense claim was sustained by a preponderance of the evidence. The court may reduce or deny the award if the defendant was engaged in criminal conduct substantially related to the events. This is a reimbursement mechanism, not a grant of pretrial immunity from prosecution.
RCW 9A.16.025 provides that a person is not justified in using force against another based on the discovery of, knowledge about, or potential disclosure of the victim's actual or perceived gender, gender identity, gender expression, or sexual orientation. This forecloses a so-called "panic" defense.
