Oregon still limits how much you can raise residential rent on most units 15 years or older. For calendar year 2026 the published cap is 9.5%. For 2027 the Department of Administrative Services just posted 10% — the statutory ceiling.
You may raise rent only once in any 12-month period, never during the first year of a tenancy, and you must give at least 90 days’ written notice. Week-to-week tenancies sit outside most of these rules. New construction (first occupancy certificate less than 15 years before the notice) is exempt. Large manufactured-home parks and marinas with more than 30 spaces are capped at 6%.
How we got here. Oregon became the first state with a statewide rent cap when SB 608 passed in 2019. The original formula was 7% plus West Region CPI, with no hard ceiling. After post-pandemic inflation would have allowed increases well above 10%, the Legislature added a 10% lid in 2023 (SB 611). In 2025, HB 3054 created the lower 6% track for larger manufactured-dwelling parks and floating-home marinas. The annual number is calculated each September for the following calendar year.
For owners, the cap is a planning number, not a suggestion. Apply the rate that matches the effective date of the increase, not last year’s figure. Put the new rent, the dollar increase, and the effective date in the notice. If you miss the cap, frequency, or notice rules, statutory damages can include three months’ rent plus actual damages.
