✓ Law Verified September 2026
Washington late fee laws decide two things every renter eventually needs to know: how many days you have before a late fee can be charged, and how big that fee is allowed to be. This guide gives the Washington answer to both in plain English, plus what to do when a fee breaks the rules, verified against official Washington sources as of September 2026.

Washington Late Fee Laws at a Glance
| Grace period before a late fee | 5 days. Under RCW 59.18.170, a landlord cannot charge a late fee on rent paid within 5 days after the due date. If rent is more than 5 days late, the fee can be counted back to the first day after the due date. The landlord can still serve a 14-day pay-or-vacate notice as soon as rent is past due. |
| Cap on the late fee | NO CAP under state law. An early version of HB 1217 (2025) would have capped late fees at 1.5 percent of monthly rent per month, but the Senate removed that cap before the bill became law as Chapter 209, Laws of 2025. Some cities do set caps. |
| Must be in the written lease | YES in practice. RCW 59.18.170 allows a late fee but does not create one on its own, so the landlord needs a lease or rental agreement that sets the fee. A tenant with no written or agreed late fee term may be able to dispute the charge. UNVERIFIED: whether the statute says in so many words that the fee must be written. |
| Per-day late fees | NO RULE statewide. After the 5-day grace period, the statute lets late fees run “from the first day after the due date until paid,” so per-day fees are not banned. Local monthly caps, such as the 10 per month cap in Seattle, Tacoma and Burien, still apply to the total. |
How Much A Washington Landlord Can Charge
The cap: NO CAP under state law. An early version of HB 1217 (2025) would have capped late fees at 1.5 percent of monthly rent per month, but the Senate removed that cap before the bill became law as Chapter 209, Laws of 2025. Some cities do set caps.
With no state cap, Washington courts judge a late fee as liquidated damages. Under Wallace Real Estate Investment v. Groves, 124 Wn.2d 881 (1994), the fee can be enforced only if it was a reasonable forecast of the landlord’s actual loss and that loss is hard to calculate. A fee far larger than any real loss may be struck down as an unenforceable penalty.
Check with your court or a legal aid office about your own case.
Under the Washington late fee laws, the number in the lease is the starting point, not the last word. A fee that is legal in size can still be illegal in timing (charged before the grace period runs), in form (never written into the lease), or in how it is collected.
The Grace Period: When the Clock Actually Starts
Statutory grace period in Washington: 5 days. Under RCW 59.18.170, a landlord cannot charge a late fee on rent paid within 5 days after the due date. If rent is more than 5 days late, the fee can be counted back to the first day after the due date. The landlord can still serve a 14-day pay-or-vacate notice as soon as rent is past due.
A lease can give you more time than the Washington late fee laws require, but never less. A fee charged inside the grace period is not owed.
Three Rules Landlords Get Wrong
Must the fee be in the lease? YES in practice. RCW 59.18.170 allows a late fee but does not create one on its own, so the landlord needs a lease or rental agreement that sets the fee. A tenant with no written or agreed late fee term may be able to dispute the charge. UNVERIFIED: whether the statute says in so many words that the fee must be written.
Can it come out of your deposit? YES, generally, if the written rental agreement lets the deposit cover unpaid charges. Under RCW 59.18.280, the landlord must give a full and specific written statement of why any part of the deposit was kept, along with any refund owed.
A landlord who does not give that statement may owe you the full deposit, and a court can award up to 2 times the deposit if the failure was intentional.
Can a late fee alone get you evicted? Unpaid rent only. Under RCW 59.18.283, a tenant’s right to stay in the home cannot depend on paying anything other than rent, and money you pay must go to rent first before late fees or other charges. The 14-day pay-or-vacate notice under RCW 59.18.057 can only be used for rent.
Unpaid late fees alone should not support an eviction, but a landlord can still sue for them as a money claim.
What to Do About an Illegal Late Fee in Washington
Many tenants can pay only the rent and write down that it is for rent, since the landlord must apply it to rent first under RCW 59.18.283. You may be able to dispute a fee charged within the 5-day grace period, above a local cap, or not in your lease.
You can raise the illegal fee as a defense in an eviction case, sue for money back in small claims court (district court), or file a complaint with the Attorney General’s landlord-tenant program or your city’s renter office. Check with local legal aid about any extra penalties your city allows.
Whatever the remedy, keep paying the rent itself on time and in full. Dispute the fee separately, in writing, citing the Washington late fee laws rule it breaks, and keep a copy. Landlords rarely file a case over a disputed fee; they do file over unpaid rent, so never withhold rent to protest a fee.
Do the Math Before You Pay
Take the fee in your lease and compare it to the rent. A fee of a few percent of monthly rent is the range most Washington courts accept as reasonable; a fee that approaches a week of rent, or one that keeps growing by the day without limit, is the kind that gets thrown out.

Then check the date: count the days from the due date to the day the fee was charged, and set that against the grace period above.
Two numbers decide almost every late-fee dispute, the size of the fee and the day it was charged. Write both down before you call the landlord, because the Washington late fee laws are easiest to enforce when you can state exactly which rule was broken.
Paper Beats Memory: Protecting Yourself Going Forward
Pay rent in a way that leaves a dated record, a bank transfer, a portal receipt, a check image, so a “late” claim can be answered with a timestamp. If you know rent will be late, tell the landlord in writing before the due date; many will waive the fee once, and the message itself is evidence of good faith.
Keep every fee notice. A pattern of fees charged inside the grace period, or above the cap where Washington has one, is exactly the evidence a small-claims judge wants to see, and it is the evidence that turns one disputed fee into a refund of every fee you paid.
Recent changes in Washington: HB 1217 (Chapter 209, Laws of 2025) took effect May 7, 2025. It caps yearly rent increases at 7 percent plus inflation, with a maximum of 10 percent, and the proposed late fee cap for residential tenants was dropped from the final law.
Seattle, Tacoma and Burien cap late fees at 10 per month, SeaTac caps them at 2 percent of rent, and Redmond caps them at 1.5 percent of rent, so check your city’s rules.
Washington Late Fee Laws: Quick Answers
Is there a maximum late fee in Washington? Yes. Under the Washington late fee laws, NO CAP under state law. An early version of HB 1217 (2025) would have capped late fees at 1.5 percent of monthly rent per month, but the Senate removed that cap before the bill became law as Chapter 209, Laws of 2025. Some cities do set caps.
Can my landlord charge a late fee that is not in my lease? YES in practice. RCW 59.18.170 allows a late fee but does not create one on its own, so the landlord needs a lease or rental agreement that sets the fee. A tenant with no written or agreed late fee term may be able to dispute the charge.
UNVERIFIED: whether the statute says in so many words that the fee must be written.
Can I be evicted for an unpaid late fee? Unpaid rent only. Under RCW 59.18.283, a tenant’s right to stay in the home cannot depend on paying anything other than rent, and money you pay must go to rent first before late fees or other charges. The 14-day pay-or-vacate notice under RCW 59.18.057 can only be used for rent.
Unpaid late fees alone should not support an eviction, but a landlord can still sue for them as a money claim.

Using the Washington Late Fee Laws Without Starting a War
The Washington late fee laws are only useful to a tenant who reads the lease first. Find the late-fee clause, check its amount and its trigger date against the rules on this page, and write down what the lease actually says before you dispute anything.
If the fee breaks the Washington late fee laws, say so in writing and pay the rent itself on time anyway, an illegal fee is a small-claims problem, while unpaid rent is an eviction problem. Under the Washington late fee laws, the renter who keeps paying rent and disputes only the fee is the one who wins.
