Dedicated statute

The notice periods in Oregon

How much warning is required before a higher rent can take effect, and how a fixed lease is treated.

When	Notice in Oregon	What it means
First year of tenancy	No increase allowed	A landlord may not increase rent during the first year after the tenancy begins.
After the first year	90 days	At least 90 days written notice before the effective date, and no more than one increase in any 12-month period, under ORS 90.323.
Fixed-term lease	None mid-term	During a fixed-term lease the rent is fixed until renewal. After the first year, an increase needs 90 days notice and cannot exceed the annual cap.
Limit on the amount	Separate rule	Oregon caps the annual increase at the lesser of 10 percent or 7 percent plus West Region inflation. The figure is recalculated and published every September, so it changes yearly and is not printed here. Buildings under 15 years old are exempt from the cap, so check the building age first.
Local ordinance	Varies	Portland layers additional rules, including relocation assistance in some cases, so check the city before treating the state rule as complete.
If notice is skipped	Not effective	Three protections stack: no increase in the first year, then 90 days written notice, then a ceiling on the amount recalculated every September. The exceptions matter as much as the rule, because buildings under 15 years old sit outside the cap entirely, so a renter first question is often how old the building is.

Recent or pending change

The scheme was amended repeatedly, most recently in 2023, and the FindLaw mirror has served superseded Oregon text, so confirm ORS 90.323 and 90.324 against oregon.public.law or the official ORS. The cap percentage changes every year and must not be relied on without its year.

Next steps if your rent is going up

Concrete, neutral steps to check a rent increase in Oregon. This is legal information, not legal advice.

Know there is no increase in year one
Oregon bars any rent increase during the first 12 months of a tenancy. So an increase in your first year is not allowed, whatever the notice.
Check whether the cap applies to your building
Buildings under 15 years old are exempt from the amount cap. So the first question is how old the building is, because a new building can raise rent above the annual ceiling.
Confirm 90 days and once per year
After the first year, an increase needs at least 90 days written notice and cannot happen more than once in any 12-month period. If either is missing, the increase is improper.
Get local help
A local Oregon legal aid office can confirm this year cap figure and whether your building is exempt. Search for legal aid in your area, and check any Portland rule.

This is general legal information, not legal advice. Read your own lease and check for a local ordinance, since either can change the notice that applies to your home.

What Oregon renters get wrong

Oregon was the first state in the country to cap rent increases statewide and it still has the most complete scheme. Three protections stack. Nothing at all in the first year, then ninety days of written notice under ORS 90.323, then a ceiling on the amount under ORS 90.324, recalculated every September against West Region inflation at the lesser of ten percent or seven percent plus inflation. Rent may not rise more than once in any twelve-month period. The exceptions matter as much as the rule, because buildings under fifteen years old sit outside the cap entirely, so an Oregon renter first question is how old the building is. The cap figure changes every year and must never be relied on without its year, and because the FindLaw mirror has served stale Oregon text before, the current numbers should be confirmed against the official statutes. For an Oregon renter the practical order is: no increase in year one, then check the building age to see whether the amount cap applies, then confirm the ninety days and the once-a-year limit.

Common questions

What is this year Oregon rent cap?

It is the lesser of 10 percent or 7 percent plus West Region inflation, recalculated and published every September, so the exact figure changes each year. This page does not print a number, because a stale figure would mislead. Confirm the current cap for the relevant year.

Does the cap apply to my building in Oregon?

Not if the building is under 15 years old, which is exempt from the amount cap. So a new building can raise rent above the annual ceiling, which is why the building age is the first thing to check.

Can my rent rise in the first year in Oregon?

No. Oregon bars any rent increase during the first 12 months after the tenancy begins. An increase can only come after the first year, with 90 days notice and within the annual cap.

Where does the CPI number come from in Oregon?

From the September annual 12-month average change in the Consumer Price Index for All Urban Consumers, West Region. The Oregon Department of Administrative Services calculates and publishes the maximum increase each year by September 30.
