Is my rent increase illegal in Oregon? The 2026 checklist

Check an Oregon rent increase for the annual limit, first-year and frequency rules, written notice content, 90-day timing, mail days, exemptions, and Portland duties.

Oregon's 2026 standard annual rent-increase limit is 9.5% for covered tenancies, but the percentage is only one part of a valid increase. The first year, frequency, tenancy type, notice content, delivery method, property classification, and Portland rules can change the answer.

Use the exact paper notice and envelope when possible. Oregon's timing can depend on whether the notice was personally delivered, sent only by first-class mail, or served through another statutory path. A document's printed date is not a substitute for the real service facts.

1. Identify the covered tenancy and annual row

Start with who owns the structure, what the agreement rents, the facility size if a manufactured-home space is involved, and whether the unit is regulated affordable housing. Standard dwelling tenancies, resident-owned manufactured homes in facilities, and week-to-week arrangements can use different provisions. Do not select a row from the property's appearance alone.

For a covered standard tenancy in 2026, compare the exact increase percentage with the 9.5% figure published by Oregon DAS. A $1,800 rent moving to $2,000 rises about 11.11%. That is a signal to examine coverage and exemptions, not a substitute for the remaining notice review.

2. Check the first year and increase frequency

ORS 90.323 generally restricts increases during the first year and limits how often rent may increase after that, with separate treatment for specified tenancies. Preserve the tenancy start date and the effective date of the last increase. A lease renewal, ownership transfer, or property-manager change does not automatically erase the existing rental agreement or rent history.

If dates are uncertain, ask for a rent ledger and prior notices. Mark an unknown as unknown. A checker that assumes the most favorable history can understate the issue, while a response that confidently invents a prior date can undermine credibility.

3. Read every required item on the notice

Oregon requires written notice that states the increase amount, the new rent, and the effective date for covered increases. Compare those fields with one another. A correct new rent paired with a different dollar increase or an impossible percentage is a recordkeeping and notice problem that should be clarified before payment changes.

Keep all pages and attachments. If the landlord claims an exemption, affordable-housing rule, manufactured-home provision, or local exception, ask which provision applies and for the facts that support it. A property sale by itself does not create a new tenancy or authorize a different rent.

4. Count the notice period and mailing days

For many non-week-to-week tenancies after the first year, ORS 90.323 uses at least ninety days' written notice. ORS 90.155 adds three days when a required notice is served only by first-class mail. That is why an Oregon notice planned as exactly ninety days can be short when it is mailed.

Use the mail-deposit or personal-delivery date, not merely the date typed on the page. Then check the effective date and rental period. Save the envelope and postmark. If the landlord used both mail and attachment, review the specific combined-service rule instead of automatically adding or subtracting three days.

5. Add Portland rules only inside Portland

Portland can require local notice language and relocation assistance when covered increases meet the city's thresholds. The bedroom count, increase within the relevant period, tenant request, property coverage, and any exception can matter. Nearby Beaverton, Gresham, Hillsboro, or Tigard addresses do not inherit Portland's code merely because they are in the metro area.

Check the city boundary and current PCC 30.01.085 materials. Preserve any relocation-rights notice and landlord exemption statement. The statewide cap and Portland program are separate: an increase can pass the state amount rule yet raise a local relocation issue.

6. Make a written record before escalating

A useful Oregon response states the rent math, notice dates, delivery facts, unresolved provision, and requested correction or documentation. If an amount above the cap has already been paid, list each payment and request a written accounting without assuming an award. ORS 90.323 provides a statutory remedy for specified violations, but a checker result is not a judgment.

Keep mailing proof and a communication log. Oregon prohibits specified retaliatory conduct after protected tenant activity under ORS 90.385, subject to statutory conditions and exceptions. Oregon Law Help can connect renters with current information and legal-aid intake; an eviction or termination deadline needs prompt attention.

A final Oregon evidence review

Before relying on the checklist, compare the lease, renewals, rent ledger, earlier increases, complete notice, envelope, and any exemption or Portland attachment. Put uncertain dates and classifications in an open-questions list. The strongest response distinguishes a confirmed calculation error from a record the landlord still needs to provide.

If a corrected notice arrives, keep it beside the original rather than replacing the old file. Record its new service date, method, amount, and effective date, then run the calculation again. A correction can change future obligations without resolving every earlier payment or communication.
