Washington Squatters Rights and Adverse Possession Laws (2026)
Washington requires 10 years of continuous, open, and hostile possession to claim adverse possession under RCW 4.16.020. Two separate 7-year tracks apply when a claimant holds color of title. Removal of a squatter requires an unlawful detainer action under RCW 59.12; self-help removal is prohibited.

Adverse Possession in Washington: The 10-Year and 7-Year Periods
Washington law gives a would-be adverse possessor two possible timelines, depending on the nature of the claimant's title documents.

The 10-year base period (RCW 4.16.020)
The default rule comes from RCW 4.16.020, which sets a 10-year limitations period on actions for the recovery of real property. A person who occupies land for 10 continuous years without the owner's permission and who meets all five elements of adverse possession can bring a quiet-title action at the end of that period.
The 7-year track with connected title of record (RCW 7.28.050)
RCW 7.28.050 cuts the period to 7 years when the possessor holds a connected title in law or equity that is deducible of record. In plain terms, the claimant must be able to point to a recorded chain of title documents that connect back to a recognizable source, even if that chain contains a defect. If the claimant has such a connected title and maintains actual, open, and notorious possession for 7 successive years, an action to recover the land must be brought within 7 years after possession began. After that window closes, the claimant's title is quieted by operation of the statute.
The 7-year track with color of title and tax payment (RCW 7.28.070)
RCW 7.28.070 provides a parallel 7-year path aimed at a slightly different situation. Under this section, a person in actual, open, and notorious possession under a claim and color of title made in good faith who also pays all taxes legally assessed on the property during the entire 7-year period is held and adjudged to be the legal owner at the end of that period. Successor owners who acquire the property by purchase, devise, or inheritance can tack their predecessor's possession and tax payments onto their own to satisfy the 7-year requirement, as long as possession and tax obligations remain uninterrupted.
The five elements required in all Washington adverse possession claims
Whether the claimant relies on the 10-year or the 7-year track, Washington courts require proof of all five elements throughout the statutory period:
- Actual possession. The claimant must physically use the land in the manner a reasonable owner would use it, such as farming, landscaping, fencing, or building structures.
- Open and notorious possession. The use must be visible and obvious, putting the true owner on notice that someone is asserting a claim.
- Exclusive possession. The claimant cannot share possession with the true owner or with the general public.
- Hostile possession. The claimant must occupy the land without the owner's permission. Possession under a license or with the owner's consent does not satisfy this element.
- Continuous possession. The claimant must maintain possession without significant interruption for the entire statutory period. Brief absences that are consistent with normal ownership patterns do not break continuity.
If any element is missing for any portion of the statutory period, the clock resets and the claim fails.
How to Remove a Squatter in Washington
Washington property owners must follow the court-supervised unlawful detainer process to remove a squatter. Self-help removal, which includes changing locks, removing the occupant's belongings, or shutting off utilities to force someone out, is illegal in Washington and exposes the owner to civil liability.

Step 1: Serve a written notice to vacate
Under RCW 59.12.030, a person who enters upon the land of another without permission and remains after receiving 3 days' written notice to vacate is guilty of unlawful detainer. The notice must be served in the manner specified in RCW 59.12.040, which allows personal service, service on a person of suitable age and discretion at the premises, or posting and mailing if no one is present.
If the squatter has any characteristics of a residential tenant, such as paying occasional rent or receiving mail at the property, the owner should also review the Residential Landlord-Tenant Act under RCW 59.18 before serving notice. Residential tenants receive longer notice periods under RCW 59.18.650, and a court may scrutinize whether an occupant qualifies as a tenant.
Step 2: File an unlawful detainer complaint
If the squatter does not vacate after the notice period expires, the owner files a complaint for unlawful detainer in the superior court of the county where the property is located. The complaint is governed by RCW 59.12.070. The court issues a summons requiring the defendant to appear and answer, typically within 7 to 30 days depending on the circumstances.

Step 3: Obtain a writ of restitution
After the hearing, if the court rules in the owner's favor, it issues a judgment and a writ of restitution under RCW 59.12.090. The writ directs the county sheriff to remove the occupant and restore possession to the owner. The sheriff carries out the actual removal; the owner does not do so personally.
No expedited sheriff squatter-removal statute in Washington
Washington has not enacted any 2024 or 2025 statute creating an expedited administrative process for sheriff removal of squatters outside of the standard unlawful detainer framework. Property owners in Washington must use RCW 59.12 and obtain a court judgment before the sheriff will act.
Document everything
Owners should photograph the property before and after occupation, keep records of any communications with the occupant, save utility and tax records, and retain copies of all legal notices served. These records become evidence in the unlawful detainer proceeding and in any future quiet-title defense.
