A plain-English guide to the age of consent in Washington State, cited to RCW 9A.44.079. A genuine close-in-age allowance is built into the rape-of-a-child statute itself.

Overview

Washington sets its practical age of consent at 16. Below that age, the state’s rape-of-a-child statutes are graded by both the victim’s specific age and the size of the gap between the two people, with a genuine close-in-age allowance built into each tier rather than offered as a separate defense.

For a victim 14 or 15, RCW 9A.44.079 only applies where the perpetrator is at least 48 months, or four years, older. Below that gap, this statute does not reach the conduct at all. A related, narrower allowance of 36 months applies to a younger victim, ages 12 or 13, under a more serious statute.

Close-in-age rules in Washington

The gap thresholds differ by the victim’s specific age band:

  • Victim 14 or 15: the perpetrator must be at least 48 months, or four years, older for rape of a child in the third degree to apply.
  • Victim 12 or 13: the perpetrator must be at least 36 months, or three years, older for the more serious rape of a child in the second degree to apply.
  • Victim 16 or older: neither statute applies, and Washington treats the person as able to consent.
A parallel statute covers sexual contact without intercourse. Child molestation in the third degree, RCW 9A.44.089, uses the same 48-month threshold for a victim 14 or 15, so the close-in-age allowance applies consistently whether or not intercourse occurred.

Exceptions and defenses

Because the statute does not reach conduct below its own gap threshold, there is nothing to defend against under that specific section in that situation, distinct from an affirmative defense raised in court. Marriage to the victim is a stated exclusion from RCW 9A.44.079. This guide did not find a reliable official source describing a separate mistake-of-age defense for these statutes.

Practical examples

These are simplified, hypothetical illustrations only, not legal advice, and not a prediction of any real case’s outcome.

Example 1. A 15-year-old and an 18-year-old, a three-year gap. Because the gap is under 48 months, RCW 9A.44.079 does not reach this conduct.

Example 2. A 15-year-old and a 20-year-old, a five-year gap. This meets the 48-month threshold, so rape of a child in the third degree applies, a class C felony.

Example 3. A 13-year-old and a 17-year-old, a four-year gap. Because the victim is 12 or 13, the narrower 36-month threshold applies, and this gap meets it, making rape of a child in the second degree, a class A felony, applicable.

Frequently asked questions about Washington

What is the age of consent in Washington?

16. Below that age, RCW 9A.44.079 and related statutes apply gap-based thresholds depending on the victim’s specific age.

Does Washington have a Romeo and Juliet law?

Informally, yes. A genuine allowance is built into RCW 9A.44.079: for a victim 14 or 15, the statute does not apply if the gap is under 48 months.

Is the threshold really 48 months, or 24 months?

The statute’s own text, confirmed directly on the Washington State Legislature website, sets the threshold at 48 months. A 24-month figure appears in at least one secondary source, but this guide could not confirm it against the official statute text and treats 48 months as correct.

Does the threshold change for a younger victim?

Yes. For a victim 12 or 13, the threshold narrows to 36 months under the more serious rape of a child in the second degree.

Is this a defense I would raise in court?

No. Because the statute does not reach the conduct in the first place when the gap is small enough, there is no offense under that section to defend against.

Editorial notes

This guide reflects the Revised Code of Washington as of 25 July 2026. It has not yet been reviewed by a licensed Washington attorney. One discrepancy is noted: a secondary source referenced a 24-month close-in-age threshold, but the statute’s own text, confirmed directly on the Washington State Legislature website, states 48 months. This guide uses 48 months as the verified figure.
