Washington does not allow a landlord to punish a tenant for using a legal right. Retaliation questions that reach Ken Miller & Associates, PLLC follow a familiar shape. A tenant reports a dead furnace or a mold problem, and three weeks later the rent jumps or a termination notice appears on the door. Whether that breaks the law depends on timing, motive, and what the landlord wrote down before the complaint arrived.
What counts as illegal retaliation under Washington law?
Illegal retaliation is an adverse action a landlord takes against a tenant because the tenant exercised a right protected by the Residential Landlord-Tenant Act, the state law at RCW 59.18 governing most residential rentals. RCW 59.18.240 defines a “reprisal or retaliatory action” to include — but not be limited to — the following, when the landlord takes them primarily to retaliate:
- Evicting the tenant
- Increasing the rent
- Reducing services the tenancy already included
- Increasing the tenant’s obligations under the lease
Motive separates a lawful business decision from an unlawful one. An increase applied to every unit on one schedule reads differently from one applied to a single unit two weeks after that tenant called the city.
Which tenant actions are protected?
RCW 59.18.240 protects two kinds of good-faith tenant conduct, so long as the tenant is otherwise in compliance with the Act:
- Complaining or reporting to a government agency about a suspected code, statute, or ordinance violation that may endanger the tenant’s health or safety; and
- Asserting or enforcing rights and remedies under the Landlord-Tenant Act.
A written repair request to the landlord, or use of the repair-and-deduct process in RCW 59.18.100, is protected because it counts as asserting a right under the Act. Good faith means the tenant genuinely believed the problem was real — not that an inspector later agreed. Some local ordinances add further protections, such as for tenant-organizing activity, so local rules are worth checking. Separately, RCW 59.18.580 bars ending a tenancy because the tenant or a household member was a victim of domestic violence, sexual assault, stalking, or unlawful harassment.
How does the 90-day presumption of retaliation work?
If a landlord takes one of the actions above within 90 days after a protected tenant act — or within 90 days after a governmental inspection or proceeding resulting from that act — RCW 59.18.250 creates a rebuttable presumption that the action was retaliatory, shifting the burden onto the landlord to prove a legitimate reason. Dates end up mattering more than adjectives.
The presumption has limits. If the tenant was in arrears on rent or already in breach of the lease when the landlord gave the termination notice, the statute flips the presumption — it then presumes the landlord’s action was not retaliatory. There is also no presumption against the landlord on a rent increase if the landlord’s notice specifies reasonable grounds for the increase, and the presumption on an eviction can be rebutted by showing it was not practical to make necessary repairs while the tenant stayed in occupancy. Outside the 90-day window a tenant can still prove retaliation, but the evidence has to carry the weight on its own.
Can a landlord raise rent or end a tenancy after a tenant complains?
Yes, when the reason is legitimate and was documented independently of the complaint. Washington has required just cause to end most tenancies since 2021 under RCW 59.18.650, so a landlord cannot decline to renew and stay silent about why. Each cause carries its own notice or cure period:
- Nonpayment of rent: a 14-day pay-or-vacate notice (RCW 59.12.030(3), incorporated by RCW 59.18.650(2)(a)); the tenant can stop the eviction by paying within the 14 days.
- Owner or immediate family intends to occupy the unit as a principal residence, or the owner elects to sell a single-family residence: at least 90 days’ written notice, and the owner must actually carry the stated purpose through.
- Demolition, substantial rehabilitation, or change of use: at least 120 days’ written notice.
Rent increases run on a separate track. Engrossed House Bill 1217, effective May 2025, caps most annual residential increases at the lesser of 7 percent plus inflation or 10 percent, holds manufactured and mobile-home lots to 5 percent, bars any increase during the first 12 months of a tenancy, exempts units whose first certificate of occupancy issued 12 or fewer years before the notice, and requires 90 days’ written notice as the general rule. The Washington Department of Commerce publishes the applicable maximum each year, and some cities, including Seattle, impose longer notice periods under local law.
What should a tenant do about suspected retaliation?
Build the record early, because these cases are decided on documents and dates rather than recollection.
Practical steps
- Send repair requests by email or text rather than raising them in a hallway conversation, since a timestamped message fixes the start of the 90-day window.
- File a complaint with local code enforcement to create an independent record — a report to a government agency is itself a protected act.
- Keep paying rent on time, because arrears flip the presumption in the landlord’s favor.
- Save every notice and write down when each document was delivered.
Retaliation also works as a defense in an unlawful detainer case. A tenant who was locked out has claims under RCW 59.18.290 — recovery of possession or termination, actual damages, costs, and attorney fees. A tenant whose utilities were shut off has claims under RCW 59.18.300, which add a penalty of up to $100 for each day the tenant is deprived of service, on top of actual damages, costs, and attorney fees.
How do landlords stay on the right side of the line?
Decide and document before the tenant complains, then apply the same rule to everyone. Annual rent schedules and written maintenance logs hold up better than paperwork that begins the week the notice went out. Finish the repair that prompted the complaint, keep the increase within statutory caps, and give the full notice period rather than the shortest one that seems defensible.
These disputes turn on narrow statutory windows, and the 90-day presumption rewards whoever kept better records.
