How much notice does an Oregon landlord need to raise rent?
ORS 90.323 requires at least 90 days' written notice. Add 3 days if served by first class mail.
ORS 90.323 and 90.324 - Oregon Rent Increase Rules
Short answer
For most ongoing residential tenancies in Oregon, ORS 90.323 requires at least 90 days' written notice before a rent increase, and ORS 90.324 caps annual increases at 7% plus the West Region CPI subject to a 10% hard ceiling. No increase is allowed during the first year of a month-to-month tenancy. New construction (within 15 years of the certificate of occupancy) is exempt from the cap, not the notice.
90-day written notice under ORS 90.323
The landlord must deliver written notice of the increase at least 90 calendar days before it takes effect. If served by first class mail, ORS 90.155(1)(c) adds three more days to the notice period.
First-year freeze
ORS 90.323(1) prohibits any rent increase during the first year of a month-to-month tenancy, regardless of the cap or the notice period.
Statewide rent cap under ORS 90.324
ORS 90.324 caps annual increases at the lower of 10% or 7% plus the September West Region CPI. The Oregon Department of Administrative Services publishes the maximum allowable percentage by September 30 each year for the following calendar year.
Exemptions from the cap
ORS 90.323(8) exempts units whose first certificate of occupancy was issued within the last 15 years and certain regulated affordable housing tied to a government program. The 90-day notice rule still applies to exempt units.
Once-per-12-months limit
ORS 90.323(3) limits rent increases to once in any 12-month period. Stacking two smaller increases inside a year is not allowed.
Portland relocation-assistance overlay
Portland City Code 30.01.085 (FAIR) requires landlord-paid relocation assistance when a rent increase equals or exceeds 10% over a rolling 12-month period, with limited exemptions. Check Portland local rules in addition to ORS Chapter 90.
