Statute summary
What SB 611 actually says.
In plain English:
- Annual cap = the lower of 10% OR (7% + West-Region CPI). For 2026, the West-Region CPI of 2.5% means the formula resolves to 9.5%.
- The 7% + CPI formula was added by SB 611 in 2023, replacing the original SB 608 formula of 7% + CPI capped at 10% (which let the cap drift higher when CPI was high).
- Exemption: Buildings less than 15 years old (by certificate of occupancy date), federally-subsidized affordable units, and the second unit of an owner-occupied duplex.
- Notice period: 90 days written notice for any increase. There is no 30/90 split as in California — Oregon is a single-rule statute on this point.
- First-year rule: No rent increases at all in the first 12 months of any tenancy (ORS §90.323(1)).
Full statute: ORS §90.323.

Frequently asked
Oregon rent-cap FAQ
What is Oregon SB 611?
SB 611, signed in 2023, lowered Oregon's statewide rent-cap formula from 7% + CPI (capped at 10%) to the lower of 10% or 7% + CPI. For 2026 the cap is 9.5%.
Does SB 611 cover my duplex?
Yes if you don't live in either unit. If you occupy one of the two units, the second is exempt. Triplex+ is always covered regardless of owner occupancy.
Is my new construction exempt?
Buildings whose certificate of occupancy is less than 15 years old are exempt. The 15-year window rolls forward every January, so a 2011 building loses its exemption in 2026.
How much notice do I need to give?
90 days written notice for any rent increase, regardless of size. Oregon does not have a 30/90 split like California — every increase is 90 days minimum.
Can I bank unused increases from prior years?
No. Oregon's cap is per-12-month-period only. Unused capacity does not roll forward.
What happens if I overshoot the cap?
ORS §90.323(5) makes the landlord liable to the tenant for three months' rent plus actual damages, plus reasonable attorney fees and costs. The tenant can sue or raise it as a counterclaim in any eviction action.
