Washington Late Rent Fee Laws: Limits, Grace Periods, and Penalties

For ordinary residential tenancies under RCW 59.18, Washington sets no dollar or percentage cap on late fees. The 2025 rent stabilization act, HB 1217 (2025 ch. 209), added an escalating cap of 2 percent of monthly rent in the first month past due, 3 percent in the second consecutive month, and 5 percent thereafter, but that cap sits in RCW 59.20.060(2)(j) and applies only to manufactured and mobile home lot tenancies, not to houses, condos, or apartments. Washington courts will still refuse to enforce a late fee that functions as a penalty rather than a reasonable estimate of damages. Local ordinances impose much tighter limits in some cities.

RCW 59.18.170(2) prohibits charging a late fee for rent paid within five days following its due date. If rent is more than five days past due, late fees may then be charged running from the first day after the due date, not from the sixth. A landlord may serve a pay-or-vacate notice at any time after rent becomes due, even during those five days.

RCW 59.18 contains no express written-lease clause for late fees, but a landlord has no right to a late fee unless the rental agreement creates one, and HB 1217 made a clause allowing a fee inside the five-day window a prohibited and unenforceable lease provision for agreements entered into or renewed on or after May 7, 2025.

Washington sets no statutory multiplier, but RCW 59.18.283 requires any tenant payment to be applied to rent before late fees or other charges, and bars conditioning the tenant's right to possession on paying anything other than rent. In practice an unlawful late fee is uncollectible in an eviction and cannot be the basis for terminating the tenancy.

RCW 62A.3-515 lets the holder of a dishonored check collect a reasonable handling fee, and if the check is not paid within 15 days of a notice of dishonor, interest at 12 percent plus collection costs up to $40 or the face amount, whichever is less. In a court action the statute adds treble damages capped at $300 plus reasonable attorney fees.

HB 1217 (2025 ch. 209), effective May 7, 2025, made a lease clause allowing a late fee within the five-day window an unenforceable provision for agreements entered into or renewed on or after that date, and added an escalating 2 / 3 / 5 percent late fee cap for manufactured and mobile home lot tenancies under RCW 59.20.060. It did not add a percentage cap for standard residential tenancies.

A large number of 2025 and 2026 articles claim Washington now caps residential late fees at 1.5 percent of rent, or at $75 per month. Both are wrong. Read the session law: HB 1217's late fee language was added to RCW 59.20.060, the manufactured and mobile home landlord-tenant act, and the actual figures there are 2, 3, and 5 percent, not 1.5 percent. Standard apartment and house rentals under RCW 59.18 have only the five-day rule. City law is where the real caps live: Seattle Municipal Code 7.24.034 limits total late fees to $10 per month and bans fees for preparing or delivering notices, so a Seattle rental is effectively capped at $10 regardless of the lease. Also remember RCW 59.18.283, which forces you to apply any payment to rent first, so you cannot let a late fee sit unpaid and then evict over it.
