Oregon Rent Increase Cap 2026: The 9.5% Limit and How It Works

Oregon Rent Increase Cap 2026: The 9.5% Limit and How It Works

Oregon runs one of the only statewide rent stabilization regimes in the country, and the number that governs it resets every year. For 2026 that number is 9.5% — the maximum a landlord may raise rent on an existing tenancy over any 12-month period. This is the news operators need to internalize before sending a single renewal notice this year: the cap moved, the formula behind it is fixed, and the once-per-year rule has not changed. This guide gives landlords and property managers the practical framework, anchored to the stable rules with a reminder to confirm the current-year figure.

The law and agency to build around

For Oregon, anchor every rent-increase policy to the state's statewide rent stabilization law, administered through the Oregon Department of Administrative Services / Office of Economic Analysis (OEA). Unlike most US states — where rent increases on market-rate housing are unregulated between lease terms — Oregon caps the annual increase and publishes the ceiling once a year.

The first operating rule is to treat the cap as a moving figure, not a constant. The 9.5% ceiling applies to 2026; each year the OEA recalculates and republishes it, so a policy hard-coded to last year's percentage will drift out of compliance the moment the new figure lands. The second rule is to separate business judgment (what increase the market supports) from legal procedure (what the cap and notice rules actually permit).

What changed for 2026

The headline for 2026:

• The statewide maximum rent increase is 9.5% for the year. That is the most a landlord may raise rent on a covered existing tenancy in any 12-month period.
• The cap is set by formula: 7% + CPI, calculated annually by the Oregon Office of Economic Analysis. Because CPI moves, the ceiling moves with it — confirm the current-year figure with the OEA before issuing any increase, rather than assuming 9.5% carries forward.
• Manufactured-home and marina facilities with more than 30 spaces are capped at a lower rate of 6% for the year. If you operate a larger manufactured-home community, this is the number that governs you — not the 9.5% general cap.

The 9.5% general figure and the 6% manufactured-home figure are both annual and both reset each year. Do not carry either number forward without checking the OEA's published rate for the current year.

How the cap works in practice

The stable operating rules to build around:

• Rent may be increased only once in any 12-month period. You cannot stack two increases inside a rolling year, even if each one is individually under the cap.
• The increase you apply must stay at or below the published ceiling for the year — 9.5% generally, or 6% for manufactured-home/marina facilities with more than 30 spaces.
• Newer buildings are typically exempt for their first years after construction. The exemption window is defined by statute — confirm the current exemption period before assuming a recently built property is outside the cap.
• Serve the increase with proper written notice. Where you are not certain of the required timing, confirm the current notice period with the OEA or a local attorney before sending — the wrong lead time can void the increase.

The recurring failure mode is a portfolio-wide "standard increase" template applied uniformly. Oregon does not permit that: the manufactured-home rate differs from the general rate, newer buildings may be exempt, and the once-per-year rule constrains timing per tenancy.

Common mistakes

Avoid exceeding the published annual ceiling, applying last year's percentage without confirming the current-year figure, using the 9.5% general cap on a manufactured-home/marina facility with more than 30 spaces (where 6% applies), raising rent twice inside a 12-month window, assuming a newer building is exempt without confirming the current exemption period, or serving the increase without confirming the current notice period.

Managing this in software

Your system should store the current-year cap as a configurable rate, not a constant, and flag any proposed increase that exceeds it before the notice goes out. It should apply the correct ceiling by property type — the manufactured-home/marina rate versus the general rate — and enforce the once-per-12-months rule per tenancy so a second increase inside the window is blocked. It should track each property's construction date against the exemption window, and calendar the notice lead time from the intended effective date. Treat a rent increase as a compliance event with a second review, not just a billing change.
