ORS 90.148
Landlord acts that imply acceptance of tenant abandonment or relinquishment of right to occupy

The surrender of a dwelling unit may be implied from the landlord’s acceptance of a tenant’s abandonment or relinquishment of the right to occupy. The landlord’s acceptance may be demonstrated by acts of the landlord that are inconsistent with the existence of the tenancy. A landlord’s receipt of the keys to the dwelling unit or a landlord’s reasonable efforts to mitigate the landlord’s damages by attempting to rent the dwelling unit to a new tenant shall not constitute acts inconsistent with the existence of the tenancy. Reasonable efforts to mitigate damages include preparing the unit for rental. [1999 c.603 §2] Note: 90.148 (Landlord acts that imply acceptance of tenant abandonment or relinquishment of right to occupy) was added to and made a part of ORS chapter 90 by legislative action but was not added to any smaller series therein.
