The Oregon 30-day notice to terminate a month-to-month lease is a document that either the landlord or the tenant in a month-to-month tenancy can use to cancel their agreement with thirty (30) days’ notice to the other party. Under state law, a landlord is only permitted to terminate a monthly rental agreement without cause in the first year of tenancy. Therefore, after the monthly tenancy has continued past one (1) year, the landlord must provide justification as with any other residential lease. When a tenant is lawfully given this notice, they must quit their rental unit before the notice expires to avoid a formal eviction.
