How much can rent increase in Oregon?

Short answer

For most ongoing residential tenancies, an Oregon rent increase is generally capped at the statewide annual maximum published each year by the Oregon Department of Administrative Services, with at least 90 days' written notice. The exact amount depends on the calendar year of the effective date, the tenancy type, the property's age, and any exemption that may apply.

When this comes up

Landlords often ask this question when planning a renewal, adjusting to rising operating costs, or evaluating a recently purchased property. The answer usually depends on the current statewide limit, how long the tenant has been in place, and whether the property qualifies for any exemption from the cap.

Oregon rule or source to check

ORS 90.324 sets the formula for the statewide annual cap and directs the Oregon Department of Administrative Services (DAS) to publish the maximum allowable percentage each calendar year. ORS 90.323 adds the 90-day written notice requirement and the first-year prohibition for periodic tenancies. Local ordinances - such as Portland's relocation-assistance rules - may add further obligations for larger increases.

Practical workflow

  1. 1. Practical workflow. 1) Identify the effective date of the proposed increase and look up the DAS-published cap for that calendar year. 2) Calculate the proposed percentage increase against the current rent. 3) Confirm the tenancy is past the first-year window and that no other increase has taken effect in the prior 12 months. 4) Check whether the property may qualify for a cap exemption. 5) Draft and serve a written notice that meets the 90-day timeline and the ORS 90.155 service rules.
  2. 2. Common mistakes. Using last year's published cap when the effective date falls in a new calendar year; assuming the cap is always 10% (the true number is whichever is lower of the formula or 10%); stacking two increases inside any 12-month window; and treating an exemption as automatic without verifying the property's certificate of occupancy date or regulatory status.
  3. 3. Related forms or workflows. Most landlords use a written rent increase notice that tracks ORS 90.323 and the current DAS-published cap. The third-party sources publishes member forms landlords can review; obtain any third-party source form directly from third-party form sources.
