Oregon Rent Increase Laws for Landlords (2026)

Updated September 2026 · Written for self-managing landlords · Not legal advice
In short: Oregon requires 90 days' notice before a rent increase takes effect, and it caps the increase itself.

What Oregon law requires

Oregon is one of the 19 US jurisdictions with a statute that speaks directly to raising rent. It requires 90 days' notice before an increase takes effect, in writing.

Citation: Or. Rev. Stat. §§ 90.323, 90.324 · read the source

The notice is not one number. 90 days after the first year of tenancy; 7 days for a week-to-week tenancy.
This rule is changing or recently changed. SB 611 (2023) lowered the formula's ceiling to the lesser of 10% or 7% plus CPI. The percentage is recalculated annually.

How much can you raise it in Oregon?

Oregon caps the annual increase at the lesser of 10%, or 7% plus the September change in the western CPI. The state publishes the resulting figure each year by September 30 for the following calendar year - look it up rather than relying on last year's number. No increase at all in the first year of a tenancy, and no more than one per twelve months. Buildings with a certificate of occupancy less than 15 years old and certain income-restricted housing are exempt from the cap but not the notice.

Oregon is one of only four US jurisdictions that caps the amount. California, Oregon, Washington and the District of Columbia are the whole list. Everywhere else the limit is what the market and your tenant will bear.
Local rules override this. Some Oregon cities, Portland among them, add relocation-assistance obligations triggered by increases above a threshold, layered on top of the state cap.

Can you raise rent mid-lease in Oregon?

No. A fixed-term lease fixes the rent for the term. An increase takes effect at renewal, or on a month-to-month tenancy after proper notice. The exception is a lease that contains its own escalation clause agreed at signing.

Serving the notice so it holds up

Most rent increases that fall apart fall apart on the date, not the amount: the notice went out too late, or nobody can prove when it went out. Count the days from delivery, not from the day you wrote it, and keep the proof.

LandlordPro generates the notice against the state's rule, dates it, records when it was sent, and carries the new rent onto the rent roll on the right day so the ledger and the notice agree.
