State Cap: Yes. Oregon caps annual rent increases at 7% plus the regional Consumer Price Index (CPI) within any 12-month period (ORS § 90.323(2)(d); ORS § 90.324).

• Exceptions: The cap does not apply to buildings under 15 years old (ORS § 90.323(5)(a)), government-subsidized affordable housing (ORS § 90.323(5)(b)), and manufactured dwelling or floating home space rentals (ORS § 90.323(7); ORS § 90.600).

Notice Period: Landlords are prohibited from increasing rent at all during the first year of a tenancy (ORS § 90.323(2)(a)). After the first year, landlords must provide at least 90 days‘ advance written notice for month-to-month and fixed-term leases (ORS § 90.323(2)(b)). Week-to-week tenancies require 7 days‘ written notice before the effective date (ORS § 90.323(1)).

Proof of Service: Notice must be delivered in writing (ORS § 90.155). First-class mail or personal in-hand delivery constitutes legal proof of service (ORS § 90.155(1)(a)-(b)). Posting the notice on the tenant’s door (combined with first-class mail) or sending it via email are acceptable if explicitly authorized in a signed written rental agreement or addendum (ORS § 90.155(1)(c)-(d)).

Prohibited Acts: Landlords cannot raise rent during the first year of occupancy or impose a rent increase in excess of the statutory annual cap on non-exempt units (ORS § 90.323), increase rent as retaliation against tenants for reporting housing code violations, joining a tenant organization, or asserting statutory rights (ORS § 90.385), or adjust rental terms for discriminatory reasons under Oregon fair housing law (ORS § 659A.145).
