Oregon rent increase notice checklist

Short answer

A complete Oregon rent increase notice generally needs at least 90 days' written notice under ORS 90.323, a clear statement of the new rent and effective date, an amount at or below the current statewide cap, and a delivery method allowed under ORS 90.155 with dated proof of service.

When this comes up

This checklist is useful any time a landlord plans a rent change on a month-to-month or other periodic tenancy. It is especially common at the end of the first year of occupancy, when a fixed-term lease rolls into month-to-month, or when adjusting rents on a recently acquired property.

Oregon rule or source to check

ORS 90.323 sets the 90-day written notice requirement for periodic-tenancy rent increases and prohibits an increase during the first year of occupancy. ORS 90.324 sets the statewide annual cap, published each September by the Oregon Department of Administrative Services. ORS 90.155 governs how a notice may be served and adds days when service is by mail.

Practical workflow

1. 1. Confirm the effective date. Pick the date the new rent will take effect. The applicable statewide cap is tied to the calendar year of the effective date, not the date the notice is served.
2. 2. Verify the amount against the cap. Look up the current Oregon Department of Administrative Services published cap and confirm the proposed percentage change is at or below it. Confirm the property is not in the first-year window and that no other increase has taken effect in the prior 12 months.
3. 3. Draft the written notice. Include the property address, current rent, new rent, dollar and percent change, effective date, and a clear statement that the change is a rent increase under the rental agreement.
4. 4. Choose a permitted delivery method. Pick a service method allowed by ORS 90.155 — personal delivery, first-class mail, or attachment plus first-class mail if the rental agreement authorizes it. Add the required extra days for mailed or post-and-mail service when counting back from the effective date.
5. 5. Serve and document. Deliver the notice and retain dated proof of service: signed acknowledgment, certificate of mailing, or a photo of posting with the matching mailing receipt. Save the proof with the property file.

Common mistakes

Counting calendar days incorrectly so fewer than 90 full days separate service from the effective date; forgetting to add mailing days for first-class or post-and-mail service; relying on text or email when the lease does not authorize that method; using last year's cap on a notice with an effective date in a new calendar year; and serving a notice during the first year of occupancy.
