Oregon notice to vacate: notice periods and mailing rules

For a month-to-month tenancy, during the first year of occupancy only: 30-day written no-cause notice for month-to-month tenancies (ORS 90.427(3)); Portland and Milwaukie locally require 90 days plus relocation assistance. After 12 months, the SB 608 just-cause regime applies: termination only for tenant cause or a qualifying landlord reason with 90 days' notice and generally one month's rent in relocation assistance (waived for landlords owning 4 or fewer units). (ORS 90.394, ORS 90.427, ORS 90.323, ORS 90.155)

If your lease requires more notice than the statute, the lease controls. Count days from the date notice is properly served, not the date you write it. Statutes change — verify the current text before serving, and treat this as a starting point, not a substitute for the statute.

ORS 90.394: a 10-day notice (deliverable no sooner than the 8th day rent is late) or a 13-day notice (no sooner than the 5th day), stating the amount due and the cure deadline; 72-hour notice for week-to-week tenancies.

Nonpayment notices are the strictest documents in landlord-tenant law: the wording, the cure period, and the service method often come straight from the statute, and a defective notice restarts the whole clock. Where your state publishes required form language, use it verbatim.

notice served by first-class mail extends the minimum compliance or termination period by 3 days, and the notice must state the extended period (ORS 90.155(2)); the mailing day counts as day zero.

Whichever method you use, keep dated proof. Certified Mail gives you a USPS record of when the notice was mailed and delivered — the fact an eviction case usually turns on.

Oregon has a statewide rent cap (ORS 90.323): one increase per 12 months, capped at the lesser of 10% or 7% plus CPI — officially 9.5% for calendar 2026 — with 90 days' written notice; buildings less than 15 years old are exempt. Just-cause eviction limits apply after 12 months of occupancy.

Local ordinances can add further requirements on top of state law — check the rules for the property's city and county before serving.

This sample notice works for a Oregon tenancy once you confirm the notice period above and any wording your statute or lease requires. Replace the bracketed fields, count the days carefully, and keep a copy of everything.
