The maximum rent increase Oregon for 2026 has been set. The Oregon Department of Administrative Services (DAS) announced that for most long-term residential rentals, landlords may raise rent by up to 9.5%.
This limit applies to properties built 15 years ago or more. Newer buildings (less than 15 years old) are not covered by this cap.
How the 9.5% Limit Was Calculated
Oregon ties rent increases to inflation, using the Consumer Price Index for All Urban Consumers in the West Region (CPI-U). The procedure is:
- Compute the 12-month change in the CPI-U (West Region).
- Add 7 percentage points to that CPI change.
- Use the smaller of that sum or 10%.
For 2026:
- CPI change = 2.5%
- 7% + 2.5% = 9.5%
- Because 9.5% < 10%, that becomes the maximum rent increase.
So the maximum rent increase Oregon landlords may impose in 2026 is 9.5%.
Special Cases & Exceptions
- Manufactured home parks and marinas with more than 30 spaces have a cap of 6%.
- If there are 30 or fewer spaces, the 9.5% limit applies.
- Newer buildings (under 15 years old) are exempt from the statewide cap.
Rules for Rent Increases
To lawfully enforce a rent increase:
- You may only increase once per 12-month period (after the first year of tenancy)
- You must give 90 days’ written notice (for long-term tenancies)
- For week-to-week tenancies, 7 days’ notice is required.
If the rules are not followed, the increase might be invalid or challenged in court.
Serving the Notice Correctly
You must deliver the increase notice properly. Acceptable methods:
- Personal delivery
- First class mail (notice served 3 days after mailing)
- If allowed in the lease, email (only for leases created or renewed after June 29, 2023) Paroa
It’s wise to keep proof, mail receipts, delivery confirmation, etc.
Portland’s Extra Rule: Relocation Assistance
In Portland, there’s an extra rule: if total housing cost increases (rent + fixed fees/utilities) reach 10% or more in a 12-month span, landlords must provide relocation assistance.
Tenants may either accept the increase or terminate tenancy and receive a one-time relocation payment.
Amounts vary by unit size:
| Type of Unit | Assistance Amount |
|---|---|
| Studio / SRO | $2,900 |
| 1 bedroom | $3,300 |
| 2 bedroom | $4,200 |
| 3+ bedroom | $4,500 |
If a landlord fails to provide the payment when required, they may owe damages plus penalties. Paroa
Other triggers for relocation help include:
- No-cause evictions
- Nonrenewal of fixed leases
- Major lease changes that harm the tenant
Some exemptions apply (shared housing, certain affordable housing units, etc.).
Final Notes
- The maximum rent increase Oregon limit ensures rent hikes are tied to inflation while protecting tenants.
- Landlords must stick to the rules and properly serve notices.
- In places like Portland, local laws may require relocation assistance when increases are steep.
