My answer is not intended to be giving legal advice and this topic can be a complex area where the advice of a licensed attorney in your State should be obtained.

Before a tenant can be evicted, written notice to the tenant (a 3 day notice or sometimes a 30 day or 60 day notice) is usually required.
This is a strict requirement before a landlord can successful sue a tenant in an unlawful detainer (eviction) lawsuit. Common exceptions when the landlord does not need to serve notice include when a lease expires and evicting an on-site property manager when the property manager's employment ends.
