The information on the page is based on the laws of the state of Washington. Landlord-tenant law is very different in different jurisdictions. Even in Washington the information on this website is not a substitute for advice about your circumstances.
Notice requirements are strictly construed against the landlord. Even if you can prove the tenant actually received the notice, failure to strictly adhere to the service methods will result in dismissal of the eviction action.
There are three acceptable means to serve an eviction notice on a tenant.
1. Delivering a copy personally to the tenant, OR
2. Substitute service on a some person of suitable age and discretion AND mailing a copy to the tenant, OR
3. If neither the tenant nor a person of suitable age and discretion is present then affixing a copy of the notice in a conspicuous place on the premises AND mailing a copy.
Mailing. When mailing is required (see above) regular first class is fine unless a lease or rental agreement requires more. One day is added by rule before the landlord can take additional actions. In effect, a three-day notice becomes a four-day notice and a ten-day notice an eleven-day notice. Mail the eviction notice from the same county.
Mailing means using the US Postal Service. The statute requires “sending a copy through the mail”. The landlord placing a copy of the eviction notice in the tenant’s mailbox is not “sending a copy through the mail”.
More than one tenant. If there is more than one person living in the property it is important to serve enough copies of the eviction notice for each person. If someone answers the door, hand that person enough copies of the notice for everyone and mail copies separately to each other tenant. Likewise if posting a copy, mail one separately to each tenant.
This does not mean multiple notices, one for each tenant. It mean multiple copies of one notice.
Posting. Notices must be posted in a conspicuous manner. Anyone should be able to walk up and read it. Therefore, do NOT fold it, leave it in an envelope, slide it under the door or through the mail slot, etc.
