Oregon Rent Increase Notice

What Oregon law says

• Legislative summary: at least 90 days written notice before a rent increase takes effect for most residential tenancies.
• No increase during the first year of a tenancy, except week-to-week, and generally once in any 12-month period.
• Cap is the lesser of 10 percent or 7 percent plus CPI; DAS says the 2027 figure is 10% and 2026 was 9.5% (ORS 90.323, 90.324).
• Exemptions include units with a first certificate of occupancy within the previous 15 years (legislative summary).

Steps for a landlord

• Confirm the tenancy is past its first year.
• Check the DAS published maximum percentage for the year.
• Give at least 90 days written notice stating the new rent.
• Confirm whether the unit is exempt before relying on an exemption.

What to put in the notice

• The tenants' names and the rental address
• The current rent and the new rent
• The date the new rent starts, after the required notice period
• The date of the notice and how it was delivered
• Your name and signature

Things to watch

• The pages we read do not describe fixed-term lease rules beyond the statutes cited; check ORS 90.323.
• Manufactured dwelling and marina rules differ; DAS directs questions to Oregon Housing and Community Services.
• Cities and counties can add their own rules, including rent control and extra notice requirements. Check your local rules too.
