FOR IMMEDIATE RELEASE
Celebration, Florida – June 8, 2025 – A recent update to the Washington Landlord-Tenant Law now requires landlords and property managers to provide proof of mailing when delivering notices such as rent increases, notices to vacate, lease amendments, and other legally binding tenant communications. The law accepts Certified Mail with USPS Washington postmark as a valid and legally recognized method of service.
To help housing professionals meet these new requirements with ease and accuracy, Certified Mail Labels offers powerful tools to generate USPS Certified Mail® and First-Class Mail® labels online, track delivery, and store compliant records—all while skipping the trip to the Post Office.
