Oregon Commercial Lease Law Guide 2026: Eviction, Seismic Retrofit, No Sales Tax & Portland CRE

1. Oregon’s Commercial Real Estate Market in 2026

Oregon’s commercial real estate market in 2026 reflects the broader national tension between remote-work-driven office softness and resilient industrial demand. Portland remains the state’s dominant commercial hub, but mid-market cities like Eugene, Bend, and Salem are attracting tenants priced out of Portland’s Pearl District and Central Eastside submarkets. Statewide, industrial vacancy has tightened considerably as last-mile logistics, cannabis operations, and life-science cold-chain users compete for functional warehouse space, while Class A office continues to digest significant new supply added over the past three years.

The Portland office market continues a prolonged correction that began post-pandemic. Class A rents in the CBD and Pearl District range from $28 to $42 per square foot per year, with concessions packages — including free rent periods of 6 to 12 months and tenant improvement allowances of $80 to $140 per square foot — still widely available. Class B office in inner Southeast Portland and the Lloyd District trades at $18 to $26 per square foot, with significantly less landlord flexibility as older buildings face capital expenditure demands from seismic retrofit ordinances.

Industrial and flex space is an entirely different story. The Airport Way corridor, Columbia Corridor, and Swan Island submarkets are posting vacancy below 5%, driving NNN rents from $9 to $15 per square foot annually for functional warehouse space. Last-mile logistics users, food-and-beverage producers, and cannabis cultivators are signing longer-term leases to lock in current rates, anticipating further tightening as developable industrial land within the Urban Growth Boundary remains constrained.

Retail in Oregon presents a bifurcated picture. Neighborhood-serving retail in high-density Portland corridors (Mississippi Avenue, Division Street, Hawthorne) commands $24 to $38 per square foot NNN. Suburban power center retail in Washington County and Clackamas County remains softer, with vacancy above 8% in some pockets, giving tenants negotiating leverage on term length and rent escalation structures.

2. Commercial Eviction: The 10-Day Notice to Pay or Quit

Oregon’s commercial eviction process is governed primarily by ORS Chapter 105 (Ownership and Rights in Real Property) and common law — not the Residential Landlord and Tenant Act codified at ORS §90. This distinction matters enormously: the consumer-protection provisions, mandatory cure rights, and lengthy notice periods that apply to residential tenants do not automatically extend to commercial relationships.

For nonpayment of rent, Oregon requires a landlord to serve a 10-day notice to pay rent or quit before filing an unlawful detainer action in circuit court. The notice must be written, identify the specific amount owed, and be properly served on the tenant at the leased premises. If the tenant tenders the full past-due amount within the 10-day window, the landlord must accept the payment and the tenancy continues — the landlord cannot refuse payment and proceed with eviction solely on the basis of a prior nonpayment.

Material Lease Violations Beyond Nonpayment

For commercial lease breaches other than nonpayment of rent — unauthorized use, subletting without consent, failure to maintain required insurance, or nuisance — the notice period and cure rights are determined almost entirely by the lease agreement itself, since ORS §90’s specific notice requirements do not apply to commercial tenancies. A well-drafted Oregon commercial lease will specify:

• A notice period for monetary defaults (commonly 5 to 10 days after written notice)
• A cure period for non-monetary defaults (commonly 30 days, with a reasonable extension if the cure cannot be completed in 30 days but the tenant has commenced diligent cure efforts)
• Whether and how many times a tenant may cure the same default within a 12-month period before losing cure rights
• Landlord’s right to self-help remedies upon uncured default (note: Oregon courts are skeptical of self-help eviction and commercial landlords should exercise caution)

Once an unlawful detainer action is filed and the landlord prevails, the court issues a judgment for restitution of the premises and may award past-due rent, attorneys’ fees if the lease so provides, and costs. Oregon does not have a specific commercial eviction fast-track statute comparable to some other states, so timelines from filing to writ of execution typically run 30 to 75 days depending on circuit court docket conditions and whether the tenant contests the action.

3. Landlord’s Lien Abolished — ORS §87.162

One of Oregon’s most tenant-friendly commercial lease provisions is statutory: Oregon expressly abolished the common-law landlord’s lien on a tenant’s personal property. ORS §87.162 states plainly that no landlord’s lien on the personal property of a tenant exists in this state.

In many states, a landlord’s lien gives the property owner the right to seize tenant personal property — furniture, equipment, inventory, fixtures — as collateral for unpaid rent, without going through court proceedings. Oregon removed this remedy entirely. This has significant practical implications for both parties.

For Tenants

• Your inventory, equipment, and business personal property are not automatically encumbered by a landlord’s lien upon lease execution
• A landlord who tries to seize, lock out, or impound your property without a court order may face civil liability for conversion and wrongful interference with business
• Your business assets remain available to secure SBA loans, equipment financing, and other lender relationships without a competing landlord lien clouding the collateral

For Landlords

• You cannot self-help by seizing tenant goods — you must pursue judicial remedies for unpaid rent
• If you want a security interest in tenant personal property, you must negotiate a separate contractual security agreement and perfect it by filing a UCC-1 financing statement with the Oregon Secretary of State under ORS Chapter 79 (Oregon’s UCC Article 9)
• A UCC-1 filing creates a perfected security interest that will be subordinate to any prior-perfected lenders but gives you a position superior to unsecured creditors in a tenant bankruptcy

4. Holdover Rules: Month-to-Month by Default

When a commercial tenant remains in possession of Oregon leased premises after the lease term expires — without executing a new lease or formal extension — the holdover tenancy is governed by a combination of the original lease terms and Oregon common law. Oregon courts generally treat a commercial holdover tenant whose rent is accepted by the landlord as a month-to-month tenant under the same terms and conditions as the expired lease, except that either party may terminate on at least 30 days written notice.

This default outcome — month-to-month continuation — is economically mild and often insufficient to motivate tenants to vacate or finalize renewal negotiations. As a result, virtually all professionally drafted Oregon commercial leases include explicit holdover penalty provisions designed to make staying past the lease expiration financially painful.

Typical Oregon Holdover Rent Structures

Tenants should negotiate holdover provisions carefully. A reasonable approach: 150% for the first 60 days, no consequential damages liability if the tenant provides at least 90 days advance notice of its intent not to renew, and mutual termination rights on 30 days notice once the holdover period exceeds 3 months. Landlords with a specific incoming tenant lined up will resist limitation on consequential damages, but this is a negotiable point in most Portland market transactions.

5. Assignment & Subletting Under Oregon Law

Oregon commercial lease assignments and subleases are governed almost entirely by the lease agreement, not by statute. ORS Chapter 91 does not impose specific restrictions on a landlord’s right to withhold consent to assignment, unlike some states that require reasonableness as a matter of law. This means Oregon tenants have no statutory right to assign or sublease without consent unless the lease expressly grants such rights.

The practical consequence: the reasonableness standard for landlord consent — if applicable — must be negotiated into the lease at the outset. Tenants in stronger bargaining positions should push for explicit lease language requiring the landlord not to “unreasonably withhold, condition, or delay” consent to assignment or subletting. Without such language, an Oregon commercial landlord may have broad discretion to refuse consent for any reason or no reason at all.

Key Assignment Provisions to Negotiate

• Permitted transfers: Assignments to affiliates, parent companies, subsidiaries, or entities resulting from a merger or acquisition should be permitted without landlord consent or with a simple notice requirement
• Profit-sharing on subleases: Many Oregon leases include a 50/50 split of any sublease profit (sublease rent minus base rent) between tenant and landlord — negotiate this down or cap the landlord’s share
• Recapture rights: Some landlords include the right to recapture the space upon assignment request rather than approve a new tenant — this is particularly problematic if the tenant has valuable below-market rent or significant remaining TI value in the space
• Assignor liability: Oregon common law generally does not release the original tenant from lease obligations upon assignment unless the landlord expressly agrees. Negotiate a release or at minimum a cap on post-assignment liability

6. Seismic Retrofit & Cascadia Earthquake Lease Provisions

The Cascadia subduction zone — a 700-mile offshore fault running from Northern California to British Columbia — presents one of the most significant structural risks in North America. Scientists estimate a major Cascadia event (magnitude 8.0–9.2) could occur within the next 50 years, with Portland and Eugene directly in the highest-impact zones. This seismic risk has translated into concrete regulatory obligations that are reshaping Oregon commercial lease negotiations in ways that have no parallel in most other states.

Portland’s Unreinforced Masonry (URM) Ordinance

The City of Portland enacted its Unreinforced Masonry Building Ordinance to require structural retrofits on the roughly 1,600 URM buildings in the city — older brick structures built before modern seismic codes. The ordinance establishes a mandatory compliance timeline with deadlines for owner notification, engineering assessment, and retrofit completion. Buildings with high occupant loads face earlier deadlines. The retrofit costs are substantial:

The Lease Cost-Allocation Problem

The central lease dispute arising from the URM ordinance is who pays for the retrofit. Under a triple-net lease with broad capital expenditure pass-through language, a landlord may argue that mandatory seismic retrofits are a recoverable operating expense amortized over the useful life of the improvement. For a tenant occupying 10,000 square feet of a 50,000 square foot building that undergoes a $3 million retrofit, the potential pass-through exposure — amortized over 20 years — could add $3.00 per square foot annually, or $30,000 per year in additional occupancy cost.

This exposure is not hypothetical — Portland tenants in older brick buildings are already receiving notice from landlords of planned retrofit projects and the corresponding pass-through obligations. The lease language that governs this outcome was typically negotiated years before the ordinance’s compliance timeline became imminent, leaving many tenants with inadequate protections.

Protective Lease Language for Seismic Costs

Tenants negotiating new Oregon commercial leases should insist on the following provisions to protect against seismic retrofit exposure:

• Structural capital exclusion: Explicitly exclude from operating expenses any costs associated with seismic retrofitting, structural reinforcement, or compliance with the Portland URM Ordinance or any state seismic mandate
• Capital expenditure cap: Cap annual pass-through of amortized capital expenditures at $1.00 to $2.00 per square foot regardless of actual costs
• Mandatory retrofit disclosure: Require the landlord to disclose as a lease condition whether the building is subject to any pending or anticipated URM compliance obligation, with a right to terminate if the retrofit cost exceeds a stated threshold
• Force majeure for seismic events: Include business interruption and rent abatement provisions triggered by earthquake damage that renders the space partially or fully unusable — and ensure the landlord’s rebuilding obligation is clearly stated with a timeline
• Insurance coordination: Confirm that the landlord’s property insurance includes earthquake coverage and that the tenant’s business interruption insurance coordinates with the landlord’s restoration timeline

7. Portland Business License & Local Tax Pass-Throughs

Oregon’s absence of a state sales tax does not mean tenants are free from all tax-related lease complexity. Portland and Multnomah County have developed a layered local tax structure that creates genuine ambiguity about what costs landlords may legitimately pass through as operating expenses in commercial leases.

The Portland Business License Tax

The City of Portland imposes a Business License Tax (BLT) on net income from business activity conducted within Portland. Real estate owners and property management companies are subject to this tax on rental income earned from Portland properties. The current rate is 2.2% of net income, with a minimum tax of $100 and a maximum tax varying by gross receipts tier.

The lease dispute: some Portland landlords with broadly drafted operating expense provisions attempt to pass through a portion of the Portland BLT as an “other tax or assessment” related to the property. Tenants should resist this characterization because the BLT is an income tax on the landlord’s business, not a property tax or an expense of operating the building. Industry-standard lease drafting in Portland — following national norms — excludes income taxes, franchise taxes, and business license taxes of the landlord from recoverable operating expenses.

Portland Clean Energy Surcharge

Portland voters approved the Clean Energy Surcharge (PCES), a 1% tax on retail sales above $1 billion annually within the city, with proceeds funding clean energy programs. This tax applies to qualifying large retailers, not directly to commercial landlords. However, tenants who are large retailers subject to PCES face an additional operating cost that should be factored into occupancy cost modeling for Portland retail locations. Smaller businesses below the $1 billion threshold are not affected.

Oregon Corporate Activity Tax Impact

The Oregon Corporate Activity Tax (CAT), effective 2020, imposes a 0.57% tax on Oregon commercial activity above $1 million in annual receipts. For large commercial tenants with substantial Oregon operations, the CAT is a cost of doing business that is separate from lease costs. Landlords do not typically attempt to pass through the CAT as a lease operating expense, but tenants should ensure that any future Oregon commercial activity taxes or gross receipts taxes levied on property owners are explicitly excluded from operating expense definitions.

8. Oregon vs. Other States: Key Commercial Lease Law Comparison

Oregon’s most distinctive advantage relative to peer states is the complete absence of a sales tax on commercial rent. Florida’s 5.5% commercial rent sales tax — which applies to base rent, CAM, and most other lease charges — adds $33,000 per year in tax expense on a $600,000 annual rent obligation. Oregon tenants pay zero. This single factor makes Oregon occupancy cost modeling materially more predictable and favorable than Florida for comparable spaces.

Oregon’s longer 10-day nonpayment notice period also provides tenants more runway than California, Texas, New York, or Florida — all of which use 3-day notices. For tenants with occasional cash flow variability, the 10-day window is meaningful breathing room to resolve payment issues before formal eviction proceedings commence.

9. 12-Step Oregon Commercial Lease Negotiation Guide

1. Confirm the governing statute: Verify that the lease is commercial, not residential. Commercial leases are governed by ORS Chapter 91 and common law — not the residential ORS §90 provisions. Ensure the lease does not inadvertently incorporate residential tenant protections that create ambiguity about applicable rights and remedies.
2. Run a URM building check: Before signing any lease in a Portland building constructed before 1980, request a URM compliance status report from the Portland Bureau of Development Services. A building on the mandatory retrofit list with an upcoming compliance deadline is a material fact that must be disclosed and addressed in lease cost-allocation provisions.
3. Negotiate the operating expense definition aggressively: Oregon leases — particularly NNN leases — give enormous scope to operating expense disputes. Push for explicit exclusions of: (a) seismic retrofit capital costs, (b) Portland and Multnomah County income and business license taxes, (c) management fees above 3–4% of gross rents, and (d) capital expenditures except as amortized within a stated annual cap.
4. Address holdover rent penalty upfront: Negotiate a graduated holdover premium that starts at 125% and reaches 150% — resist 200% escalators. Also negotiate a notice-of-non-renewal grace period: if you give the landlord 120 or more days advance notice that you will not renew, the holdover penalty should be reduced or waived for up to 60 days while transition logistics are resolved.
5. Secure assignment and subletting rights: Ensure the lease contains explicit language that landlord consent “shall not be unreasonably withheld, conditioned, or delayed.” Define permitted transfers that require only notice, not consent: affiliates, subsidiaries, parent companies, successors by merger or acquisition. Limit the landlord’s recapture right to situations where the proposed rent exceeds current market rent.
6. Draft a force majeure clause covering seismic events: Oregon’s standard force majeure clauses often cover typical natural disasters but may not explicitly address the prolonged business disruption scenario of a major Cascadia earthquake. Include provisions for: rent abatement during restoration, a landlord obligation to begin restoration within 60 days of damage, and a tenant termination right if restoration is not completed within 18 months.
7. Lock in the 10-day cure right: While Oregon statutory law provides a 10-day pay-or-quit period, confirm the lease does not shorten this period through contractual notice provisions. Some landlords draft leases with a 5-day cure period for monetary defaults — shorter than the statutory minimum — which creates ambiguity about whether the statutory or contractual period controls. Negotiate 10 days or more.
8. Confirm earthquake insurance obligations: Standard commercial property insurance in Oregon does not include earthquake coverage. Determine whether the landlord carries earthquake insurance on the building. Determine whether the tenant’s business interruption coverage includes earthquake triggers. Negotiate lease language requiring the landlord to maintain earthquake insurance on the structure throughout the lease term.
9. Address Portland business license tax pass-through risk: Insert explicit language excluding Portland Business License Tax, Multnomah County Business Income Tax, Metro Supportive Housing Services Tax, and any similar landlord income, franchise, or gross receipts taxes from the definition of recoverable operating expenses. This single provision can save tens of thousands of dollars annually in avoided disputed pass-throughs.
10. Negotiate a realistic tenant improvement allowance: Portland’s office market in 2026 supports TI allowances of $80 to $140 per square foot for Class A space on 5- to 10-year leases. Industrial TI allowances are significantly lower ($10 to $30 per square foot). Ensure the lease specifies disbursement conditions, milestone payment triggers, a deadline for landlord disbursement with a lien-free mechanic’s lien waiver requirement, and a tenant’s right to offset against rent if the landlord fails to disburse timely.
11. Build in expansion and contraction options: In Portland’s current office market — where landlord concessions are available — negotiate a right of first offer on adjacent space and a contraction option allowing you to reduce your footprint by 15 to 20% after year 3 or 4 with adequate notice. The contraction option is particularly valuable for technology and professional services tenants whose headcount may fluctuate.
12. Have the lease reviewed by AI before your attorney: AI lease review tools can scan a 50-page Oregon commercial lease in minutes, flagging missing standard protections, unusual operating expense definitions, and seismic retrofit risk language — giving your attorney a prioritized list of issues to focus on rather than spending billable hours on routine initial review. Use AI review as a first pass, then engage Oregon commercial real estate counsel for negotiation strategy on the flagged provisions.

10. Six Oregon Lease Red Flags to Watch For

11. 12-Item Oregon Commercial Tenant Lease Checklist

• URM Building Status: Confirm whether the building is subject to the Portland Unreinforced Masonry Ordinance and request written landlord disclosure of any pending or anticipated retrofit obligation or cost estimate.
• Seismic Retrofit Exclusion: Verify the operating expense definition explicitly excludes costs associated with seismic retrofitting, structural upgrades, or compliance with the Portland URM Ordinance or any state seismic mandate.
• 10-Day Cure Period Preserved: Confirm the lease provides at least a 10-day cure period for monetary defaults, consistent with Oregon’s statutory notice framework, and does not contractually shorten this period.
• Landlord’s Lien Language Absent: Confirm the lease does not purport to grant the landlord a lien on tenant personal property. Any security agreement and UCC-1 filing should be disclosed to all existing and future lenders.
• Income Tax Exclusion from Operating Expenses: Verify that the operating expense definition explicitly excludes Portland Business License Tax, Multnomah County Business Income Tax, Metro Supportive Housing Services Tax, and any other landlord income or franchise tax.
• Holdover Rent Structure: Confirm the holdover penalty is graduated (not 200% from day one), that consequential damages liability is capped, and that the tenant can terminate the holdover on 30 days written notice.
• Assignment and Permitted Transfer Rights: Verify the lease contains a “not to be unreasonably withheld” consent standard and includes explicit permitted transfers for affiliates, subsidiaries, and merger/acquisition scenarios requiring only notice.
• Earthquake Insurance Requirements: Confirm whether the landlord is required to carry earthquake insurance on the building and whether tenant business interruption insurance must include seismic event coverage.
• Force Majeure and Rent Abatement: Confirm the lease includes rent abatement rights triggered by earthquake or other casualty rendering the space partially or fully unusable, with a landlord restoration timeline and tenant termination right if restoration is delayed beyond 18 months.
• TI Allowance Disbursement Terms: Verify the tenant improvement allowance disbursement conditions, timeline for payment, lien waiver requirements, and the tenant’s right to offset against rent if the landlord fails to disburse timely.
• Expansion and Contraction Options: Confirm any negotiated rights of first offer on adjacent space, contraction options, and renewal options are properly documented in the lease body or a rider — not just in the letter of intent.
• Capital Expenditure Cap: Verify the NNN lease contains an annual cap on amortized capital expenditure pass-throughs (typically $1.00 to $2.00 per square foot) to limit exposure from major building system replacements and mandated structural improvements.
