Washington's Residential Landlord-Tenant Act (RLTA, RCW 59.18) is one of the strongest tenant-protection statutes in the country. It governs eviction procedures, security deposit requirements, habitability standards, and notice requirements for residential tenancies. Understanding it matters for STR hosts for one specific reason: the line between "STR guest" and "residential tenant" is not as clear as most hosts assume.
This article provides general educational information and is not legal advice. Consult a Washington-licensed attorney for guidance on any specific situation involving a guest who has overstayed or asserted tenancy rights.
Key takeaways
- STR guests (stays under 30 days with a booking through Airbnb/VRBO) are not residential tenants under Washington law and do not have RLTA eviction protections. Airbnb's own policies govern the relationship.
- Once a guest stays for 30 days or more — regardless of the original booking structure — they may acquire certain residential tenancy rights in Washington, requiring a formal legal process to remove them.
- "Holdover guests" — guests who refuse to leave after checkout — are a trespass situation in the short-stay context, but can become a tenancy situation if you accept payment or delay taking legal action.
- Seattle's Just Cause Eviction Ordinance applies to residential tenants, not STR guests, but applies regardless of lease length once a tenancy is established.
- The safest protection: clearly documented booking terms, check-out enforcement, and no acceptance of payment from a guest beyond their confirmed booking dates.
The STR guest vs. residential tenant distinction
Washington's RLTA defines a "landlord-tenant" relationship by the presence of a rental agreement for residential purposes. A licensed STR booking — where a guest pays for a defined short stay through Airbnb, VRBO, or direct booking — is generally treated as a transactional lodging arrangement, similar to a hotel stay, not a residential tenancy.
This means:
What the RLTA does not require you to do for STR guests:
- Provide the 20-day notice required to terminate a month-to-month tenancy
- Follow the formal eviction (unlawful detainer) process
- Return a security deposit within 21 days under RLTA procedures
- Comply with Seattle's Just Cause Eviction Ordinance
What you are still obligated to provide:
- A habitable space (functional heating, plumbing, weatherproofing)
- Safe physical conditions (working smoke detectors, carbon monoxide alarms)
- Compliance with all housing codes applicable to the structure
The guest's recourse for STR disputes runs through Airbnb's resolution process, Washington's Consumer Protection Act, or the courts — not through RLTA tenant protections.
Where it gets complicated: the 30-day threshold
Washington's courts and legislature have developed a 30-day rule that creates legal uncertainty for STR hosts who rent to guests for stays approaching or exceeding one month:
30 days or more = potential residential tenancy: If a guest occupies a unit for 30 or more consecutive days, Washington law may treat the arrangement as a residential tenancy regardless of how it was originally structured. The guest may acquire rights under the RLTA — including the right to formal notice before being required to vacate and protection from self-help eviction (changing locks without a court order).
The mechanism: Washington's RLTA defines a tenancy as occupancy under a "rental agreement," which can be oral, written, or implied by conduct. If a guest stays past 30 days and you continue accepting payment — even informally — a court may find an implied month-to-month tenancy was created, triggering RLTA protections.
The 28-night booking pattern: This is why URPM and many professional STR managers cap MTR stays at 28 nights when operating under short-term rental frameworks rather than formal lease agreements. The one-day margin is not purely administrative — it maintains the legal character of the stay as a transient lodging arrangement rather than a residential tenancy. For genuine 30+ day stays intended as mid-term rentals, a proper written lease agreement is the appropriate structure.
Seattle's additional layer: Under Seattle's Just Cause Eviction Ordinance (SMC 22.206.160), a landlord must have one of 18 specified "just causes" to terminate a residential tenancy. This ordinance applies whenever a residential tenancy has been established — and courts have applied it to stays that crossed the tenancy threshold even without a formal lease.
Holdover guests: what to do when a guest won't leave
A "holdover guest" — someone who remains in your property past their checkout date — is among the most operationally stressful STR situations. Here's how the law applies:
For stays under 30 days at checkout time:
A guest who overstays an STR booking has exceeded their license to occupy the property. This is legally closer to trespass than tenancy. Your options:
- Contact Airbnb's host support immediately. Airbnb has an overstaying guest protocol and can attempt to contact the guest and facilitate resolution. Document all contact attempts.
- Do not accept any payment from the guest for the additional days beyond their original booking — not through Airbnb, not in cash, not through Venmo. Accepting payment can create an implied new tenancy, which complicates removal.
- Contact local police if the guest refuses to leave after being asked. For a short-stay overstay with no tenancy formed, this is a trespass situation and police can assist with removal. Police may still decline to become involved if there's any ambiguity about whether a tenancy exists.
- Do not change the locks or remove the guest's belongings yourself. Even in a trespass situation, self-help eviction — physically removing someone or their property without a court order — creates civil liability in Washington. If the situation escalates, consult an attorney.
If the stay has reached or exceeded 30 days:
The situation is more complex. At this point, a court may find that a tenancy exists. Attempting to physically remove the guest without following the formal unlawful detainer (eviction) process — even if their "booking" has expired — creates legal exposure. Consult a Washington landlord-tenant attorney before taking any physical action to remove the occupant.
The formal unlawful detainer process in Washington requires:
- Written notice (typically 3-day or 20-day, depending on the basis for termination)
- Filing of an unlawful detainer action in Superior Court if the occupant doesn't comply
- A court hearing and judgment
- A writ of restitution authorizing the sheriff to physically restore possession
In King County, this process typically takes 4–8 weeks from initial notice to actual removal.
Practical protections: how to stay on the right side of the line
Use proper lease documentation for 30+ day stays: Any stay of 30 days or more should be structured as a formal written lease under Washington's RLTA — not as a "long-stay" Airbnb booking. This doesn't eliminate tenant rights (RLTA applies to leases), but it documents the relationship clearly, specifies the move-out date, and prevents ambiguity about what the parties agreed to. URPM's MTR lease agreements are drafted for Washington law by attorneys familiar with the STR-to-tenancy boundary.
Cap STR booking lengths at 28 nights: For properties operated as STRs rather than MTRs, set Airbnb's maximum booking length at 28 nights to maintain the legal character of all stays.
Document checkout compliance: Confirm checkout completion (walkthrough photos with timestamp) immediately after the guest's departure time. If a guest hasn't left by checkout, document your contact attempts and responses. This timeline documentation matters if a dispute escalates.
Require verified identity: Airbnb requires identity verification from guests, which matters if law enforcement involvement becomes necessary. For direct bookings, require a government-issued photo ID before check-in.
Frequently asked questions
Can I call the police if an Airbnb guest won't leave after checkout? Yes, for stays under 30 days. The guest's license to occupy the property expired at checkout, and their continued presence is trespass. However, police may decline to physically remove someone if there's any reasonable basis to believe a tenancy exists — particularly if the stay is approaching 30 days or if you've accepted any additional payment. Document the checkout date and your contact attempts before calling.
Does Seattle's renter protection ordinance apply to Airbnb guests? Generally no, for standard short-term stays. Seattle's Just Cause Eviction Ordinance applies to "rental units" occupied under residential tenancies. A properly structured STR stay is not a residential tenancy. However, if a guest's stay crosses into tenancy territory — 30+ days, acceptance of payment beyond the booking, or other tenancy-establishing conduct — Seattle's ordinance may apply.
What if the guest claims they're a tenant to avoid leaving? This happens. A guest who understands Washington's tenant protections may attempt to assert tenancy status to delay removal. The strength of your position depends on: whether the stay is under 30 days, whether you've accepted any payment beyond the original booking, and the documentation you have of the original booking terms. If there's any ambiguity, consult a landlord-tenant attorney before proceeding.
