Oregon Commercial Lease Requirements

In Oregon, a written commercial lease is a practical necessity for any business tenancy. The lease serves as the primary governing document, and its terms are enforced by the courts with minimal intervention from statutory protections.

Written Lease Required

Under the Statute of Frauds, any lease for a term of one year or longer must be in writing and signed by both parties. Given that commercial leases typically run 3-10 years, a written agreement is universally required.

Essential Clauses

1. Parties and Premises: Full legal names of entities and the exact address/suite of the leased space (including rentable vs. usable square footage).
2. Lease Term: Start date, end date, and any renewal or extension options.
3. Rent Structure: Base rent, payment schedule, and lease type (NNN, Gross, Modified Gross).
4. Rent Escalation: Exact method for future increases (CPI, fixed %, market review).
5. Operating Expenses / CAM: Definition of pass-through expenses, base year, and reconciliation process.
6. Permitted Use: What business activities the tenant may conduct.
7. Maintenance and Repairs: Clear allocation of structural vs. interior responsibilities.
8. Insurance: Types and minimum amounts, including naming landlord as Additional Insured.
9. Default and Remedies: Definition of default, cure periods, and landlord's remedies.
10. Assignment and Subletting: Conditions for transferring the lease.
11. Surrender/Make Good: The condition the premises must be returned in.
12. Personal Guarantee: If applicable, binding the business owner personally.

Oregon-Specific Considerations

• Oregon Business Tax: Commercial tenants in Oregon are subject to the state's Corporate Activity Tax (CAT). Leases should address whether CAT and other business taxes are the tenant's sole responsibility.
• Portland Business License Tax: Properties within Portland may trigger additional local tax obligations for the tenant.
• Earthquake/Seismic Considerations: Oregon's location in the Cascadia Subduction Zone makes seismic risk a significant factor. Leases should address insurance coverage and repair obligations for earthquake damage.

Best Practices

• Use Experienced Commercial Real Estate Attorneys: Oregon commercial leases require specialized legal knowledge.
• Negotiate TI Allowances Clearly: Define Tenant Improvement (TI) allowances, construction oversight, and ownership of improvements at lease end.
