A lease can say almost anything, but in Washington a signed clause isn’t automatically an enforceable one. The Residential Landlord-Tenant Act (RLTA), chapter 59.18 RCW, overrides lease terms that take away rights the statute gives tenants. At Ken Miller & Associates, PLLC, we review rental agreements for landlords and tenants in Okanogan County and across the state, and many disputes start with template language written for another state or an older version of Washington law.
Can a landlord put anything in a Washington lease?
No. Under RCW 59.18.230(1)(a), any lease provision that waives part of the RLTA is against public policy and unenforceable. The rest of the lease survives.
The rule applies to oral agreements too, and even when the tenant signed willingly. RCW 59.18.360 allows certain waivers in narrow circumstances, but its conditions are strict and it rarely fits an ordinary rental. Routine terms like rent, due dates, and pet rules are fine.
Which lease terms are prohibited under RCW 59.18.230?
Washington lists specific terms a rental agreement cannot contain. Under RCW 59.18.230(2), a lease may not require a tenant to:
- Waive rights or remedies under the RLTA, or give up the right to sue the landlord, including through a class action
- Sign a nondisclosure agreement about the lease, such as its rent, deposits, or concessions
- Authorize a confession of judgment, which is advance consent to a court judgment without a chance to defend
- Pay the landlord’s attorney fees, except as the RLTA allows and a court actually awards
- Release the landlord from liability the law imposes, or indemnify the landlord for it
- Accept an arbitrator chosen at signing, or arbitrate at all unless the landlord pays the full cost and the agreement is notarized
- Pay rent only by electronic means
The class action and nondisclosure limits were added in 2025 and apply to leases entered into or renewed on or after July 27, 2025. A landlord who knowingly uses a lease with prohibited terms can owe the tenant actual damages, statutory damages of up to two times the monthly rent, court costs, and reasonable attorney fees.
What late fees are legal in Washington?
Under RCW 59.18.170, a landlord can charge a late fee only when rent is more than five days past due. State law doesn’t set a flat or percentage cap on most residential late fees, but the fee has to appear in the rental agreement, and a charge far beyond the landlord’s real cost of late payment invites a challenge that it’s an unenforceable penalty. RCW 59.18.283 adds two limits. Every payment must be applied to rent before late fees, damages, or other charges, and a tenant’s right to stay can’t be conditioned on paying anything other than rent. In an eviction judgment, RCW 59.18.410 limits late fees to $75 total.
Can a lease penalize a tenant for leaving early?
Only within limits. A tenant who breaks a fixed-term lease can still owe rent, but a clause can’t erase statutory protections. The Tenants Union of Washington State points to a common example: language forfeiting the entire deposit as a penalty for leaving early may be an illegal waiver.
Deposit handling follows RCW 59.18.280 no matter what the lease says. Within 30 days after the tenancy ends and the tenant moves out, the landlord must send a full and specific statement of any amount kept, and an intentional failure can cost up to twice the deposit. Service members (RCW 59.18.220) and domestic violence survivors (RCW 59.18.575) also hold early termination rights that a lease cannot remove.
Are termination clauses enforceable in Washington?
A clause letting the landlord end a tenancy for any reason, or with simple notice, generally won’t hold up. Since 2021, RCW 59.18.650 has required a legally recognized cause to evict, refuse to continue a tenancy, or end a month-to-month tenancy. Tenants on month-to-month agreements can still end the tenancy with at least 20 days’ written notice before the end of a rental period under RCW 59.18.200.
How do Washington’s 2025 rent rules change lease clauses?
House Bill 1217, codified at RCW 59.18.700 and effective May 7, 2025, limits rent increases and the lease terms tied to them. Rent can’t rise at all during the first 12 months of a tenancy. After that, increases are capped at the lesser of 7 percent plus inflation or 10 percent over 12 months. The statute doesn’t fix this number — the Department of Commerce calculates it each year from the Seattle-area Consumer Price Index and publishes it, so confirm the current cap before raising rent. Every increase requires 90 days’ written notice under RCW 59.18.140, and rent can’t differ by more than 5 percent based on the type of lease. An automatic escalation clause that exceeds these limits is a liability.
