Oregon Rent Increase Rules
Oregon rent increases are shaped by tenancy type, timing, property age, exemptions, and the current statewide annual limit. This page walks through when the rules apply, what landlords should check before sending a notice, the underlying ORS sections to review, and a practical workflow for moving from decision to delivered notice.
Short answer
For most ongoing residential tenancies, Oregon requires at least 90 days' written notice before a rent increase, restricts increases during the first year of occupancy, and caps the annual increase at the statewide maximum published each year by the Oregon Department of Administrative Services. Some properties - including qualifying newer construction and certain regulated housing - are exempt from the cap but still subject to the notice rules.
When Oregon rent increase rules apply
The rules generally apply to residential rentals covered by ORS Chapter 90, including month-to-month and other periodic tenancies. Whether a specific increase is allowed depends on the tenancy type (periodic vs fixed-term), how long the tenant has occupied the unit, the property's age and any exemption status, the timing of any prior increase in the last 12 months, and the annual limit in effect on the increase's effective date.
Key things landlords should check
Before sending a rent increase notice, confirm: (1) the tenant has occupied the unit for at least 12 months; (2) no other increase has taken effect in the prior 12 months; (3) the proposed percentage stays at or below the current published annual limit; (4) whether the property qualifies for a cap exemption (for example, qualifying newer construction or certain affordable housing); (5) the effective date is at least 90 days after the notice will be delivered; and (6) the delivery method satisfies ORS 90.155, including any added mailing days.
Oregon rule to review
The core statutes are ORS 90.323 (90-day notice and first-year prohibition for periodic tenancies) and ORS 90.324 (the statewide annual cap formula and the publication of the maximum allowable percentage). ORS 90.155 governs how notices may be served. Local ordinances, such as Portland's relocation-assistance rules for larger increases, may layer additional obligations on top of the state rules.
Practical rent increase workflow
1) Confirm the tenancy is past the first-year prohibition. 2) Look up the published Oregon rent increase limit for the calendar year of the effective date. 3) Calculate the proposed new rent and confirm the percentage change is at or below the limit (or that an exemption applies). 4) Draft a written notice stating the current rent, the new rent, the dollar and percent increase, and the effective date. 5) Choose a delivery method allowed by ORS 90.155 and count backwards at least 90 full days (plus any mailing days). 6) Serve the notice and retain dated proof of service in the tenant file.
Common mistakes
Serving the notice fewer than 90 full days before the effective date; forgetting to add mailing days when service is by first-class mail or post-and-mail; using the wrong calendar year's limit when the effective date crosses into a new year; raising rent during the first year of occupancy; stacking two increases inside any 12-month window; relying on text or email as the only delivery method; and assuming a cap exemption applies without verifying the property's certificate of occupancy date or regulatory status.

Common Oregon questions
What is the current Oregon rent increase limit?
Oregon publishes the annual maximum allowable percentage each year through the Department of Administrative Services. Always verify the current published rate before serving notice.
Can I raise rent in the first year of an Oregon tenancy?
Generally no. ORS 90.323 prohibits rent increases during the first year of occupancy for periodic tenancies, with limited exceptions tied to fixed-term agreements that already include a scheduled change.
