When can a rent increase start in Oregon?

Choose the state and the date the notice is given.

How much notice is required

Written notice at least 90 days before the increase takes effect, or 7 days for week-to-week tenancies. The notice must state the increase amount, the new rent and the effective date. If the increase is above the cap, it must also state the facts supporting the exemption. It must be served by personal delivery or first-class mail; by mail, 3 days are added. Days are counted as calendar days. (ORS 90.323(1)–(3); ORS 90.155(2); ORS 90.160)

Applies toWhenNotice
Month-to-month—90 days
Fixed-term lease at renewal—90 days
Week-to-week—7 days
  • The notice must be in writing.
  • Mailed notice: add 3 days.

Example: a notice handed over on November 2, 2026 in Oregon

Earliest date the new rent can start, with rent due on the 1st, worked out from the Oregon rule above:

  • For a month-to-month tenant of 1 year raising rent 5% or a month-to-month tenant of 3 years raising rent 12%: Sunday, January 31, 2027
  • For a week-to-week tenant raising rent 5%: Monday, November 9, 2026

Is there a limit on how much rent can go up?

The state publishes the maximum each year by September 30 for the next calendar year: 9.5% for 2026 and 10% for 2027. A landlord who raises rent above the cap owes the tenant 3 months' rent plus actual damages. A landlord who ends a tenancy without cause in the first year can't charge the next tenant more than the cap would have allowed. (ORS 90.323(2)(c)–(d), (4)–(6); ORS 90.324)

Formula:
7% plus CPI (West Region CPI-U, September 12-month average), but never more than 10%
2026 maximum:
9.5% (Oregon Dept. of Administrative Services, Office of Economic Analysis)
2027 maximum:
10% (Oregon Dept. of Administrative Services, Office of Economic Analysis)
Not covered:
Units whose first certificate of occupancy was issued less than 15 years before the notice date. Also regulated affordable housing where the tenant's share does not rise, or where the change is required by program rules or a change in income.
How often:
No increase in the first year of the tenancy; after that, no more than once in any 12-month period

Raising rent during a lease

Rent can't be raised in the first year of any tenancy. Oregon's legal aid handbook says the landlord generally can't raise the rent until a fixed-term lease ends, except in some subsidized housing when income changes. (ORS 90.323(2)(a); OregonLawHelp Renter's Handbook on Rent Increases)

City and county rent control

Cities and counties may not enact any ordinance or resolution controlling rent. Exceptions: rents on subsidized or incentive-contract properties, limited condominium-conversion rules, and temporary controls in a declared emergency. (ORS 91.225)

  • Portland: A rent increase of 5% or more over a rolling 12 months needs at least 90 days' written notice, or longer if the lease says so. If the increase is 10% or more in 12 months, the tenant may ask in writing within 45 days for relocation assistance: $2,900 (studio/SRO) to $4,500 (3+ bedrooms), paid within 31 days.

Retaliatory rent increases

A landlord may not retaliate by raising rent after the tenant has done any of the following: complained to a government agency or in good faith to the landlord, joined a tenants' union, testified against the landlord, won an eviction case in the past 6 months, or asserted other legal rights. The tenant gets the remedies of ORS 90.375 and a defense to eviction. The statute sets no presumption period. (ORS 90.385)

Also good to know

  • A tenant who would rather move must give written notice of termination; OregonLawHelp says month-to-month renters must do this 30 days before the rent increase date.
  • Manufactured-home and floating-home spaces follow ORS 90.600 instead. For parks with more than 30 spaces the yearly cap is 6% (ORS 90.324(1)(a)).
  • Subsidized and public housing have different rent rules.

Other Oregon renting rules in numbers

Security deposit
No statewide limit. During the first year a landlord may not add a new or larger deposit, except one tied to an agreed change such as allowing a pet. After the first year, the tenant gets at least 3 months to pay a new or larger deposit. Return deadline: 31 days after the tenancy terminates.
Notice for unpaid rent
10 days (pay or move out)
How a written notice is delivered (eviction-notice rules)
Personal delivery; first-class mail (adds 3 days); first-class mail plus attachment to the main entrance if a written rental agreement allows it for both sides; or email if both parties signed a separate email addendum after move-in, but a termination notice by email must also be sent by first-class mail (ORS 90.155(1), (5)).
Notice for other lease violations
14 days (fix it or move out)
