Washington Landlord-Tenant Law 2026: The Plain-English Guide
Washington's Residential Landlord-Tenant Act (RLTA) sits in the middle nationally but has been moving tenant-friendly in recent years — the nonpayment notice went from 3 days to 14 days in 2019, and just-cause eviction protections expanded. Seattle adds its own layer on top.
Security deposits
- No state cap on the amount.
- Return within 21 days of move-out, with a written itemized statement.
- Trust account: deposits must be held in a trust account; you must give the tenant a written receipt plus the bank name and address.
- Move-in checklist: you must provide a written checklist at move-in, signed by both parties. Without it, you generally can't withhold for damages.
- Penalty: bad-faith withholding = up to 2x the deposit plus attorney's fees.

Rent rules
- No rent control — state law preempts local rent control.
- Late fees must be in the lease and reasonable.
- Raising rent: 60 days' written notice for month-to-month tenancies — longer than most states. See how to raise rent legally.
Eviction in Washington
- Nonpayment: 14-Day Notice to Pay or Vacate (not 3 days — the 2019 change).
- Lease violations: 10-Day Notice to Comply or Vacate.
- Just cause: for many tenancies, you now need a valid cause to decline renewal or terminate — "I just want them out" isn't enough.
- Cases go to Superior Court (unlawful detainer) — more formal and slower than small-claims-style courts. Expect 6–10 weeks for uncontested cases, longer if contested.
Self-help is illegal. Full process: how to evict a tenant.
Repairs and habitability
- Strong implied warranty of habitability; Seattle's housing code adds aggressive enforcement.
- Tenant remedies after proper written notice: repair-and-deduct (with strict dollar limits and procedures), terminate the lease, or sue for damages.
- Retaliation protections are broad — adverse action within 90 days of a tenant complaint is presumed retaliatory.
Entry rights
- 48 hours' written notice required, entry at reasonable times.
- 24 hours for showing the unit to prospective tenants/buyers (with written notice).
- Emergencies and abandonment are exceptions.
Seattle: the extra layer
Seattle requires just cause for evictions, mandates 60–120 days' notice for certain terminations, requires landlords to accept the first qualified applicant in some cases (first-in-time rule, with exceptions), and enforces winter eviction moratoriums in some years. Seattle landlords should treat city rules as a separate compliance track.
The bottom line
Washington demands patience: 14-day notices, 60-day rent increase notices, 48-hour entry notices, superior court evictions. Landlords who build these timelines into their processes do fine; those who treat it like Texas get burned.
