Example

If $1,500 rent is due on the 1st, Washington law bars a late fee while payment is within the five days following the due date. If the rent remains unpaid after that protected period, RCW 59.18.170 allows a lease-authorized fee to run from the first day after the due date. There is no statewide dollar formula in that section, and local rules may be stricter.

How Washington's five-day late-fee rule works

The five-day protection delays when a landlord may charge the fee; it does not necessarily erase the earlier late days once rent is more than five days past due. The same statute also lets a tenant request a written due-date change of up to five days when regular monthly government assistance arrives after the contractual due date and the statutory conditions are met.
