A growing number of states are reinforcing the use of Certified Mail to ensure proper documentation and communication between landlords and tenants. In Washington State, specific legal statutes—especially under the Residential Landlord-Tenant Act (RCW 59.18)—now require landlords and property managers to use Certified Mail when delivering certain legal notices to tenants.
Understanding the New Certified Mail Requirements for Washington Property Managers
If you're a property manager or landlord in Washington, understanding this requirement is not optional. It is the key to staying compliant, protecting your legal rights, and ensuring any court proceedings or notices hold up under scrutiny.
Why Certified Mail Is Required Under Washington Law
Certified Mail provides proof of mailing and proof of delivery for every mail piece. That's something ordinary mail cannot guarantee. Under Washington law, landlords are allowed to use Certified Mail in several critical scenarios, such as:
- Service of 10-day notice to comply or vacate
- Notification of tenant responsibilities during repair disputes
- Delivery of important legal or court-related documents
- Serving alternative notice when personal service is not possible
For example, RCW 59.18.060 allows Certified Mail as one method of delivering notice when a landlord is informing a tenant of an alleged lease violation. It ensures that the sender has a verifiable mailing record and can confirm that the notice was sent to the correct address.
When it comes to real estate and rental disputes, having that certified receipt can be the difference between a dismissed case and a favorable legal outcome.
Postmark Must Be from Washington: Why It Matters—and How to Ensure Compliance
One important detail in Washington’s updated landlord-tenant laws is that Certified Mail must be postmarked within the state of Washington. This provision ensures that notices are mailed locally, helping protect tenants' rights and giving landlords a clearer legal timestamp for compliance.

The Role of the USPS in Certified Mail
The United States Postal Service (USPS) offers Certified Mail as a secure way to send important documents with added tracking and delivery verification. It includes:
- A unique tracking number
- Delivery confirmation with a timestamp
- Optional Return Receipt (Electronic or physical) showing who signed for it
- Proof of mailing for legal purposes
While this service is widely recognized and legally accepted, many landlords and property managers struggle with the traditional, manual Certified Mail process when mailing letters.
The Challenge: Certified Mail Can Be Time-Consuming
Property managers are often responsible for multiple rental units, complex documentation, and strict legal timelines. Taking time out of the day to go to the Post Office, fill out forms, attach green cards, and track delivery manually is inefficient.
Some common challenges include:
- Delays in sending notices due to limited Post Office hours
- Clerical errors with handwritten addresses or forms
- Difficulty storing and retrieving receipts for legal use
- Time spent waiting in line instead of managing rental properties
These challenges increase as portfolios grow or legal situations become more urgent.
