Oregon is a tenant-protective commercial leasing jurisdiction compared to most Western states, reflecting the state's broader regulatory philosophy around housing and business tenancies. Commercial tenancies are governed by the Oregon Landlord-Tenant Act (ORS Chapter 90) only for residential purposes; commercial tenancies instead fall under ORS Chapter 91 and common law. However, Oregon courts have developed a commercial landlord-tenant jurisprudence that imposes meaningful constraints on landlord remedies.
Oregon explicitly prohibits commercial self-help evictions. Portland and other Oregon cities do not impose a commercial rent tax. Oregon is notable for the Forcible Entry and Wrongful Detainer (FED) statute (ORS Chapter 105), which provides the exclusive judicial pathway for commercial evictions. Oregon's eviction timeline is longer than states like Nevada, and courts will scrutinize lease compliance carefully. Portland's generally tenant-friendly political environment has produced several local commercial tenant protection measures that practitioners must monitor alongside state law.

View statute →| Type | Period | Details |
|---|---|---|
| Nonpayment of Rent | 10 days | Under ORS Chapter 91, a commercial landlord must serve a 10-day written notice to pay rent or vacate before filing a Forcible Entry and Wrongful Detainer (FED) action for nonpayment. |
| Lease Violation (Non-Monetary) | 30 days | For material non-monetary lease violations, Oregon requires a 30-day notice to cure or vacate before the landlord may commence FED proceedings. |
| Month-to-Month Termination | 30 days | Under ORS Section 91.090, to terminate a month-to-month commercial tenancy, either party must provide at least 30 days' prior written notice before the end of the rental period. |
No statutory audit rights; all audit provisions must be negotiated in the lease.
Oregon provides no statutory right for commercial tenants to audit landlord CAM or operating expense reconciliation statements. All audit rights — including the look-back period, auditor qualifications, cost allocation, and record retention obligations — must be expressly stated in the lease. Oregon's tenant-protective judicial climate may provide some support for tenants challenging materially inaccurate expense statements through breach of contract litigation, but no statutory mechanism exists independent of the lease.
