While you are best-served by contacting an attorney for specific advice on your circumstances. The Oregon State Bar has an excellent referral service: Programs to Help you Find the Right LawyerAlso consider contacting OCAT to speak with their free legal aid assistance: Community Alliance of Tenants - OregonWhat follows is my personal general understanding, as someone whou2019s been a rental tenant, and property landlord. The following is absolutely not legal advice.Some parts of Oregon require a landlord gives up to 90 days advanced notice on a month-to-month agreement, most notably, Portland (Residential Eviction Notices ). Thereu2019s also u201ctenant assistanceu201d that a landlord is possibly required to pay, depending upon the specific circumstances of their notice.As a tenant, month-to-month, in all but very specific and rare circumstances, you remain responsible for rent for up to 30 days from the date you give notice. Thereu2019s no requirement to give notice on any particular day. Written notice is generally accepted as the standard means of providing notice, however your contract may modify that criteria, within particular constraints.If your goal is a shorter timeline, and if youu2019re a victim of domestic abuse, if you believe thereu2019s a habitability issue, or if you have cause for an action against your landlord, there may be ways to shorten your minimum 30 day notice period, you should talk to an attorney for specific advice.
