Can You Evict a Month to Month Tenant in Pierce County?

[Kirsten Crotts]

I am putting an offer in on a duplex who has a month to month tenant that is not paying rent on one side. I'm struggling to find information about the eviction moratorium in Pierce County and laws around evicting month to month tenants. Does anyone know if I can give the tenants 30 days notice to leave if the offer is accepted or do I need to give a full 90 days? Or can I evict them at all for not paying rent? I am planning on moving into the one side regardless.

Thank you.
