Rent Increase Rules in Oregon: 9.5% for calendar year 2026 (2026)

Quick answer

Yes — Oregon caps annual rent increases. Oregon caps annual rent increases statewide at the lesser of 10% or 7% plus the CPI-U West Region change (ORS 90.324), for rental units 15+ years old. The 2026 maximum is 9.5% (DAS announcement, Sept 2025); manufactured-dwelling/floating-home facilities with more than 30 spaces have a separate 6% cap in 2026. Increases allowed once per 12 months with 90 days' written notice.

The cap formula

Lesser of: (a) 10%; or (b) 7% + the September annual 12-month average change in the Consumer Price Index for All Urban Consumers, West Region (All Items). Oregon DAS must calculate and publish the percentage by September 30 each year for the following calendar year (ORS 90.324(1); 2019 SB 608 as amended by 2023 SB 611, Or. Laws 2023 c.226).

For the current period, that works out to 9.5% for calendar year 2026 (announced by DAS Sept 30, 2025). Separate 2026 cap of 6% for manufactured dwelling / floating home facilities with more than 30 spaces..

Who is exempt

Units whose first certificate of occupancy was issued less than 15 years before the rent-increase notice (ORS 90.600(3)(a)); certain certified/regulatory affordable-housing units where the tenant's portion is unchanged or driven by program eligibility (ORS 90.600(3)(b)). Increases limited to once in any 12-month period (ORS 90.600(1)(b)).

Notice requirements

Written notice at least 90 days before the effective date, stating the increase amount, new rent, and effective date (ORS 90.600(1)(a)). Penalty for exceeding the cap: tenant is entitled to three months' rent plus actual damages (ORS 90.600(4)).
