Oregon rent increase law

Except in a week-to-week tenancy, you may not raise the rent during the first year of the tenancy. After that, give at least 90 days' written notice, raise it no more than once in any 12-month period, and stay within the maximum the Oregon Department of Administrative Services publishes each year by September 30: the lesser of 10 percent or 7 percent plus the West Region consumer price index. In a week-to-week tenancy, give at least seven days' written notice.

ORS 90.323 ORS 90.324

• The notice must state the amount of the increase, the new rent, the date it takes effect and, if the increase is above the cap, the facts supporting the exemption. ORS 90.323(3)
• The percentage cap does not apply when the unit's first certificate of occupancy was issued less than 15 years before the date of the increase notice, or to certain regulated affordable housing. The first-year bar, the 90 days and the once-a-year limit still apply. ORS 90.323(5)
• An increase above the cap costs three months' rent plus the tenant's actual damages. ORS 90.323(6)
• If you end a tenancy without cause during the first year, the next tenant's rent may not exceed what the cap would have allowed for the old tenancy. ORS 90.323(4)
• The rent in a fixed term tenancy may not be changed by one side alone during the term. ORS 90.220(2)
• Portland adds relocation assistance when a tenant receives an increase of 10 percent or more within 12 months and asks for it in writing within 45 days. Portland City Code 30.01.085(C) See Rent control and local rules on the Oregon page
• For tenancies subject to ORS 90.323 and its percentage cap, DAS published a 9.5 percent maximum for calendar year 2026 and a 10 percent maximum for calendar year 2027. Use the percentage for the calendar year of the increase, together with the notice, timing and exemption rules above. Manufactured-dwelling and marina space tenancies governed by ORS 90.600 follow a separate regime. DAS: corrected 2026 percentages DAS: 2027 percentages, published September 28, 2026 ORS 90.323(7), 90.324

Oregon has a statewide cap on rent increases for most homes, and cities and counties may not adopt their own rent control. The only exceptions are rent limits in contracts for subsidized low-income housing, limits during a condominium conversion notice period, and temporary controls after a disaster that wipes out much of the housing supply.

ORS 91.225

• The statewide cap is the lesser of 10 percent or 7 percent plus the index, published yearly, with an exemption for units whose first certificate of occupancy is less than 15 years old. ORS 90.323 ORS 90.324 See Rent increases on the Oregon page
• Cities and counties may still add other tenant protections. Portland requires relocation assistance of $2,900 to $4,500 for no-cause and qualifying-reason terminations and for increases of 10 percent or more, and has its own deposit and screening rules. Portland City Code 30.01.085 Portland City Code 30.01.087 Portland City Code 30.01.086
• For a covered Portland rent increase of 10 percent or more in a rolling 12-month period, a tenant has 45 calendar days after receiving the increase notice to request relocation assistance in writing. The landlord must pay within 31 calendar days after receiving that request: $2,900 for a studio or single-room-occupancy unit, $3,300 for one bedroom, $4,200 for two bedrooms, or $4,500 for three or more bedrooms. Check the city exemption requirements before claiming an exemption. Portland City Code 30.01.085(C), (I)
• Include the tenant's rights, obligations and eligible assistance amount with the increase notice and relocation payment, and report payments to the Portland Housing Bureau within 30 days. After receiving assistance for an increase, the tenant has six months from the increase's effective date to repay it and stay, or give a termination notice under the state Act. Portland City Code 30.01.085(C)-(E)

You may not retaliate by raising rent, decreasing services, serving a termination notice, or bringing or threatening an eviction because the tenant complained to a government agency about a health or safety code violation, made a good faith complaint to you about the tenancy, organized or joined a tenants' union, testified against you, successfully defended an eviction you brought in the previous six months, or asserted any right tenants have under federal, state or local law.

ORS 90.385

• Decreasing services includes unreasonably restricting common areas for tenant meetings and intentionally interfering with the tenant's use of the home. ORS 90.385(2)
• A tenant who is retaliated against has the remedies for unlawful ouster and a defense to eviction. ORS 90.385(3) ORS 90.375
• You may still evict if the complaint was made unreasonably or to harass, the tenant caused the code violation, the tenant was behind on rent when the notice was served, or code compliance requires work that makes the unit unusable. ORS 90.385(4)
• A complaint made by someone else on the tenant's behalf counts as the tenant's complaint. ORS 90.385(5)
• Using the home as a family child care home under the statute is also protected. ORS 90.385(1)(f)
