How much notice does a landlord have to give before raising the rent in Oregon?
Short answer
At a glance: 90 days; 7 days (week-to-week)
Rent increase: 90 days' written notice; none in the first year; once per 12 months; capped (9.5% in 2026, 10% in 2027)
Notice: At least 90 days before the rent increase takes effect (90 days for month-to-month or fixed-term tenancy; 7 days for week-to-week tenancy)
After the first year of a tenancy, give written notice at least 90 days before a rent increase takes effect (7 days for week-to-week), raise rent no more than once in 12 months, and stay within the state cap published each September: 9.5% for 2026 and 10% for 2027 for units 15+ years old.
