WA SB6139

Landlords must accept personal checks, cashier's checks, or money orders for rent payments, with an exception for tenants whose personal checks bounced within the previous nine months

Landlords must allow tenants to mail rental payments unless an accessible on-site payment location is provided

During late payment situations, landlords must continue accepting the same payment methods agreed upon in the rental agreement or previously accepted during the tenancy

Partial payments of past-due rent do not reinstate the lease or provide grounds for dismissing a pending unlawful detainer (eviction) proceeding, unless landlord and tenant agree otherwise in writing

Partial payments do not alter or extend the five-court-day deadline for full payment required under RCW 59.18.410 in unlawful detainer actions
