How much notice is required to raise the rent in Oregon?

Verified July 9, 2026 All Oregon topics →

Oregon caps most residential rent increases at 9.5% for calendar year 2026 and requires at least 90 days' written notice before any increase takes effect.

The cap — the lesser of 10% or 7% plus West Region inflation, recalculated and published by the state by each September 30 — has applied statewide since 2019, making Oregon the nation's first rent-stabilization state. Rent can never be raised during the first year of a tenancy and no more than once in any 12-month period afterward, and the notice must state the increase amount, the new rent, and the effective date. New buildings are exempt for 15 years from their first certificate of occupancy, as are units rented at reduced rates under government affordability programs, but even exempt landlords owe the 90-day notice with the facts supporting the exemption. Charging above the cap costs the landlord three months' rent plus the tenant's actual damages. Week-to-week tenancies need only 7 days' notice and are not capped, manufactured-home parks with more than 30 spaces have a stricter 6% limit, and cities and counties remain barred from enacting their own rent control by ORS 91.225.

Oregon rent increase notice at a glance

Notice — month-to-month 90 days
Varies by increase size Not addressed by statute
Fixed-term leases ORS 90.323 applies to every tenancy other than week-to-week, fixed-term included: no rent increase during the first year after the tenancy begins, at least 90 days' written notice before any increase takes effect, no more than one increase in any 12-month period, and no increase above the ORS 90.324(1) cap unless the unit is exempt. Week-to-week tenancies instead require 7 days' written notice and are not subject to the cap.
Statewide rent control / stabilization Yes
Rent control details Oregon was the first statewide rent-stabilization state (SB 608, 2019; cap formula amended by SB 611, 2023). ORS 90.324(1): the Department of Administrative Services (Office of Economic Analysis) calculates the maximum annual increase for the following calendar year as the LESSER of 10 percent or 7 percent plus the September annual 12-month average change in the CPI for All Urban Consumers, West Region (All Items), and must publish it in a press release by September 30. For calendar 2026 the maximum is 9.5% (7% + 2.5% CPI); 2025 was 10.0%. Exemptions (ORS 90.323(5)): units whose first certificate of occupancy issued less than 15 years before the notice date, and units where the landlord provides reduced rent under a federal, state, or local program or subsidy — exempt landlords must still give the 90-day notice stating the facts supporting the exemption. Anti-churn rule (90.323(4)): after a first-year 30-day no-cause termination, the next tenancy's rent may not exceed what the terminated tenant could lawfully have been charged. Penalty (90.323(6)): an increase violating the cap or the re-rental rule makes the landlord liable for three months' periodic rent plus the tenant's actual damages. Separate facility regime: manufactured-dwelling-park/marina tenancies (ORS 90.600) are capped at a flat 6% where the facility has more than 30 spaces (HB 3054, 2025) and at the 90.324 formula (9.5% for 2026) for 30 or fewer spaces.
Local rent control preempted Yes
Frequency limits No increase at all during the first year after the tenancy begins, and no more than once in any 12-month period thereafter (ORS 90.323(2)(a), (c)).

Notes and caveats

LIVING FIGURE — maintenance: DAS/OEA publishes the next calendar year's maximum by September 30 each year (ORS 90.324(2), via press release plus the OEA rent-stabilization page). The 2027 figure lands by 2026-09-30: the Q4-2026 sweep MUST refresh the 9.5% everywhere it appears (summary_plain, rent_control_details), mirroring the WA Commerce routine. 2026 figure triple-sourced: OEA page verbatim ('For 2026, the maximum allowable rent increase percentage is 9.5%.'), DAS newsroom post 2025-09-30 and correction 2025-10-01. STALE-SOURCE TRAPS for page copy: (1) pre-SB 611 formula was 7% + CPI with NO 10% ceiling — it produced 14.6% in 2023; any source citing that formula or figure is stale; (2) past figures still circulating: 9.9% (2022), 14.6% (2023), 10.0% (2024), 10.0% (2025); (3) '6% cap' headlines from HB 3054 (2025) apply only to 30+-space manufactured-dwelling-park/marina facilities under ORS 90.600, not apartments. rent_control_state true AND local_control_preempted true — the original statewide-cap-plus-local-preemption combination (WA copied it in 2025); 91.225's exceptions (subsidized-property rent limits, condo-conversion periods, disaster controls) don't change the headline. Portland's relocation and longer-notice ordinances survive preemption because they don't control rent (out of scope v1). Penalty scope is precise: 90.323(6) covers cap violations and the (4) re-rental rule, not bare notice defects. notice_varies_by_increase_size is null — 90 days regardless of size; above-cap (exempt) increases just add required exemption facts to the notice.

Statute citations

How this record was verified: Dual-host reads of statute text: official Oregon Legislature ORS chapter pages (oregonlegislature.gov ors090.html and ors091.html) plus the oregon.public.law mirror (current through the 2023 ORS edition and 2024 session), with verbatim re-reads of ORS 90.323(2)-(6) and 90.324(1)-(2). Every load-bearing number (31-day deposit return, 2x penalty, 4th-day late-fee grace, 6%/day and 5%/5-day fee caps, 24 hours' actual notice, 90-day increase notice, first-year bar, once-per-12-months limit, 15-year exemption, 3-months-rent penalty, lesser-of-10%-or-7%+CPI formula) was read on both hosts. The annually-published cap figure was verified on the official DAS Office of Economic Analysis rent-stabilization page (fetched twice with different prompts) and cross-confirmed against the DAS newsroom press releases of 2025-09-30 and the 2025-10-01 correction: 9.5% for calendar 2026 (CPI-U West Region September 12-month average of 2.5%). 2026 short-session sweep via the Oregon Real Estate Agency's official 2026 Legislative Update: SB 1523, HB 4120, HB 4123 all enacted, none changes a v1 field.
