Average Rent in Oregon: ZIP Rents, 2027 Limits & Portland Relocation

What the rent evidence changes for a rental decision

Match the rental to current signed leases and its actual jurisdiction. Confirm the correct calendar-year ceiling, tenancy history and notice before modeling an increase. Inside Portland, resolve relocation eligibility and exemption records and fund any payment and turnover costs before treating higher rent as available cash.

Oregon ordinary residential rent increases

Use the year of the effective increase, not a stale search result

DAS now publishes 10% for ordinary covered 2027 increases; its 2026 figure is 9.5%. The larger manufactured-dwelling and marina facilities identified on that page use a separate 6% rule. ORS 90.323 generally bars an ordinary increase in the tenancy’s first year, requires at least 90 days’ written notice afterward and limits frequency.

The published percentage is a ceiling within a legal framework, not a promised return or permission to alter a fixed lease. Tenancy type, effective year, prior increases and documented exceptions matter. Newer construction and regulated affordable housing require their own statutory review.

Decision. Verify the lease, tenancy start, increase history, supported notice/effective date and first certificate of occupancy. Use the actual applicable rule before changing income. The figure is a conditional 2027 planning case; it does not authorize a 10% ordinary increase in 2026.

What could change it. A statutory exception can change the percentage restriction without eliminating other duties. A lease or timing limit can prevent an otherwise below-ceiling increase. Do not infer exemption from a renovation or advertisement.

Records to obtain. Current lease, tenancy/increase history, served notice, effective date, original occupancy certificate and any program or exemption records.

Compare rents across these county groups

These analyst-selected sets use the listed county labels and the same September 2026 observation month. Each ZIP receives one equal vote. They are not official metro definitions, exhaustive regions or bedroom comparisons.

24 distinct county labels appear in the current sample; geographic coverage is incomplete and uneven. Only currently available observations from the same latest month enter these comparisons. Older retained records and missing ZIPs do not enter as zero rents.

Keep a possible increase and relocation cash outside the reference rent roll

Hypothetical apartment: $1,800 monthly rent, 5% annual vacancy/noncollection, no free month, $6,900 operating costs, $10,000 debt and $1,000 reserves. These are assumptions, not Oregon property estimates. Relocation, initial work and purchase cash are separate; the worksheet does not determine a lawful increase or tenant rights.

Initial calculated result: $20,520 collected rent, $13,620 NOI before debt/reserves, and $2,620 cash after debt/reserves. Change the assumptions below to test your own budget.

• Multnomah County overview — Keep a county market screen separate from Portland city-limit and tenancy determinations.
• Deschutes County overview — Investigate Central Oregon separately from the Portland apartment cohort.
• House-hack calculator — Model an actual owner-occupied small building with its own rent, expenses and financing.
• ZIP and bedroom HUD rent reference — a different measure from asking-rent ZORI; a PHA must still establish its payment standard and approve the actual contract.
• Property income calculator — use signed comparables and actual expenses for the subject property.

Oregon rent questions

How these rent figures are calculated

State: Oregon · USPS OR · Census state FIPS 41. Zillow supplies postal ZIP observations with city and county labels. We filter to valid positive rents in this state and the latest common observation month, sort the values, and take the middle value, or the mean of the two middle values for an even count. Means are the sum divided by included ZIPs. No population, household or rental-unit weighting is added.

The all-home, all-bedroom ZIP series is smoothed, not seasonally adjusted. A bedroom rent cannot be inferred from it. Membership can change after a refresh, so a change in this page’s median is not a matched-sample rent-growth rate. This edition does not publish a ZIP-sample growth claim.

Data: Zillow Research · ZORI method · National ZIP source CSV. The state benchmark is our ZIP-based calculation, not a provider-published statewide estimate. Occupied-unit Census rent, listing medians, effective broker rents and HUD gross-rent references answer different questions and are not blended here.

The observation month identifies the rent data available for this comparison. Historical or missing latest observations stay out of the current sample. Check the date before comparing a property with a newly advertised offer.

Market and legal sources below were reviewed 2026-10-24. Their own periods are shown next to each claim. Broker samples and boundaries are not fully disclosed; surveys may share underlying providers and should not be treated as independent experiments. The market interpretation is conditional research, not a property-level income guarantee. Recheck local rules, signed comparable leases and actual expenses before using an illustration in a transaction.
