Commercial Lease LOI: What to Include (and What to Leave Out) for Landlords and Tenants

Originally published: February 2026

Commercial Lease LOI: What to Include (and What to Leave Out) for Landlords and Tenants

A Commercial Lease LOI (letter of intent) is a short, written term sheet that documents the terms of a commercial lease before attorneys draft the final lease. 

A strong LOI locks the terms that change total occupancy cost, timeline risk, and operational control, then defers detailed legal drafting to the lease.

 Most LOIs remain non-binding, except for clauses expressly stated, such as confidentiality, exclusivity, and expense reimbursement.

Key Takeaways

  • A commercial lease LOI documents the core business terms before lease drafting begins.
  • A commercial lease LOI should define cost drivers and control rights, then defer legal remedies and boilerplate to the lease.
  • A clear LOI reduces lease drift and improves leverage during negotiations.

What Is a Commercial Lease LOI?

A Commercial Lease LOI is a written outline of proposed business terms between a landlord and a tenant. 

A Commercial Lease LOI reduces re-trading during lease drafting by aligning both parties on economics, timing, and responsibility allocation. 

A Commercial Lease LOI should state non-binding intent in a dedicated clause and should identify any binding carve-outs in plain language.

Include in LOI vs Leave for Lease Agreement

Include in LOILeave for Lease Agreement
Rent structure and escalation methodFull legal remedies and default mechanics
Lease term and commencement triggersDetailed default provisions and dispute procedures
TI allowance or turnkey scope summaryTechnical construction specifications and exhibits
Major rights and optionsBoilerplate definitions and operational procedures

A tenant can compare proposals more quickly when the LOI remains clean. A landlord can draft a lease more quickly when the LOI clearly defines the economics.

A tenant should treat the LOI as the decision document. The lease becomes the enforceable implementation. 

The process overview for leasing commercial space helps tenants avoid signing an LOI that quietly commits them to a lease form without review rights.

The Include List: What to Put in a Commercial Lease LOI

The Include List: What to Put in a Commercial Lease LOI

A commercial lease LOI should capture the terms that drive total occupancy cost, timeline risk, and operational control. 

A commercial lease LOI should state numbers, dates, triggers, and decision rules so the lease draft cannot rewrite the deal.

Money Terms: Base Rent, Rent Type, Escalations, Concessions, Deposits

A commercial lease LOI should state base rent as $/RSF and as a monthly total. A commercial lease LOI should identify the rent type as Gross, Modified Gross, or Triple Net (NNN). 

A commercial lease LOI should specify the escalation method and the first escalation date. A commercial lease LOI should define the rent commencement trigger and should separate lease commencement from the rent commencement when the buildout affects timing. 

A commercial lease LOI should list concessions and should define the security deposit amount and form.

Include these items in the money section

  • Base rent and rent type. Gross, Modified Gross, or NNN
  • Rent escalation method. Fixed, percentage, or CPI method
  • Rent commencement trigger. Delivery date, permit date, or fixed date
  • Free rent. Duration and start point
  • Tenant improvement dollars. Allowance or turnkey scope
  • Security deposit. Amount, timing, and refund triggers

A tenant should verify the mechanics of the expense before accepting a headline rent. The breakdown of NNN, modified gross, and full-service office leases in Alabama helps tenants map rent types to real cash flow.

Operating Expenses and CAM: What to Define at LOI Stage

A commercial lease LOI should state the operating expense structure as NNN pass-through or base-year accounting. 

A commercial lease LOI should define the concept of a controllable expense cap when expense volatility creates risk. 

A commercial lease LOI should request audit rights concept and should reserve detailed definitions for the lease.

LOI-level CAM and expense clarity

  • Operating expense structure. NNN, base year, or modified gross
  • CAM estimate. Basis and included categories
  • Controllable expense cap concept. Percentage cap and compounding rule
  • Audit rights concept. Timing and documentation access

A tenant should treat the CAM definition as a cost driver, not as a footnote. The CAM fundamentals for CAM charges are the same as those explained in the CAM charges section.

Space and Use: Premises, RSF vs USF, Use Clause, Exclusives, Parking, Hours

A commercial lease LOI should identify the premises with the building name, street address, suite number, and floor. A commercial lease LOI should state RSF and USF when available, and whether the tenant has remeasurement rights. 

A commercial lease LOI should define permitted use as a specific business activity and request exclusives when competitive protection is at issue. 

A commercial lease LOI should state parking allocation, access hours, after-hours HVAC responsibility, and any signage rights.

Use clause precision

  • A retail tenant should define the product category and service scope.
  • An office tenant should define professional service type and client traffic expectations.
  • An industrial tenant should define storage, shipping cadence, and outdoor use limits.

Time and Control: Term, Commencement Triggers, Options, Expansion, Termination

A commercial lease LOI should state the lease term in months and should define the commencement trigger. A commercial lease LOI should summarize renewal options, including the number of options, option length, notice deadlines, and rent-setting method. 

A commercial lease LOI should summarize expansion rights by identifying the expansion area and exercise window. 

A commercial lease LOI should outline early termination rights when business risk requires flexibility, including notice, fee, and concession repayment concepts.

Typical control rights to capture

  • Renewal options and rent-setting method
  • Expansion rights and first offer or first refusal framework
  • Assignment and sublease framework. Consent standard and recapture concept
  • Early termination or contraction options when needed

The Leave-Out List: What to Defer to the Lease Agreement

The Leave-Out List: What to Defer to the Lease Agreement

A strong LOI should not duplicate the lease. A strong LOI should reserve detailed legal drafting for counsel and should avoid importing boilerplate that creates conflicting language.

Legal Provisions to Defer

A commercial lease LOI should avoid full indemnity language, detailed default remedies, and insurance endorsements. 

A commercial lease LOI can reference “customary commercial terms” at a high level, then delegate the specifics to lease drafting.

Defer these to the lease.

  • Default definitions and cure periods
  • Remedies, acceleration, and attorney fee mechanics
  • Insurance schedules and endorsement requirements
  • Detailed repair and maintenance allocation language
  • Full dispute resolution procedure and venue clauses

Language Traps That Create Lease Drift

A commercial lease LOI should avoid vague terms that invite later reinterpretation. A commercial lease LOI should define the decision rule, not just the label.

Replace vague terms with decision rules

  • “Market rent” should be defined as an appraisal method or a broker panel method.
  • “Turnkey” should become scope, delivery condition, and punch list standards.
  • “Tenant pays CAM” should be a pass-through method that includes categories.

LOI Economics Table: A Format Landlords and Tenants Can Compare

A commercial lease LOI should include a single economics table that captures all cost drivers in a single view. 

A single economics table makes landlord proposals comparable and prevents tenants from judging a deal solely on base rent.

ItemLOI Term
Premises sizeRSF, plus USF if available
Base rent$/RSF and monthly total
Rent typeGross, Modified Gross, or NNN
EscalationsMethod and schedule
CAM or operating expensesStructure and estimate basis
Taxes and insurancePass-through method if applicable
Free rentDuration and start trigger
TI allowance or turnkeyDollars, scope, and timing

Negotiation Framework: How to Use the LOI to Reduce Risk

An LOI sets leverage and expectations for the entire deal. A tenant should first negotiate the cost structure, then the lease protections. A landlord should insist on clarity in exchange for speed and seriousness.

Sequencing and Leverage: What to Push First

A tenant should push first on terms that affect long-term costs. A tenant should prioritize the expense structure, TI economics, and escalation method. 

A tenant should use objective constraints, such as the buildout timeline and relocation costs, to justify concessions.

Priority sequence

  1. Rent type and operating expense structure
  2. TI dollars, scope, and delivery timing
  3. Rent commencement trigger and free rent timing
  4. Term length and renewal mechanics
  5. Assignment, sublease, and expansion framework

The negotiation workflow in negotiating a commercial lease agreement in Alabama aligns with this sequencing.

Benchmarking: What “Standard” Claims Require

A landlord should support “standard” terms with market context. A tenant should request comparable deals by asset type and submarket. A tenant should verify the effective rent after concessions, not just the face rent.

Verify these items

  • Effective rent after free rent
  • TI dollars per RSF for comparable spaces
  • Expense pass-through structure and cap feasibility
  • Renewal option rent-setting method

Special Situations That Need LOI Precision

Some deals require tighter LOI language because late-stage surprises can result in real business losses.

Tenant Improvements and Delivery: Allowance vs Turnkey

A commercial lease LOI should specify TI as either $/RSF or a lump sum and define the reimbursement timing. 

A commercial lease LOI should define the delivery conditions and should name the plan approval process. A commercial lease LOI should assign permit responsibility and should allocate delay risk.

Delivery condition language that avoids disputes

  • “As-is” should identify what systems remain the landlord’s responsibility.
  • “Vanilla shell” should list core components. HVAC, electrical stub, restrooms, and demising walls.
  • “Turnkey” should define the scope and completion standard.

Assignment, Sublease, Relocation, Co-tenancy

A commercial lease LOI should state a consent standard for assignment and sublease and define the recapture concept if the landlord requires it. 

A shopping center LOI should address co-tenancy when anchors drive revenue. A landlord relocation right should include tenant protections and cost coverage.

A tenant can reduce drafting friction by engaging tenant representation early. A tenant can see how representation supports LOI execution in commercial lease representation and in tenant representation in Huntsville.

Common LOI Red Flags for Landlords and Tenants

A commercial lease LOI should not contain accidental binding language. A commercial lease LOI should not omit the non-binding clause. 

A commercial lease LOI should not use undefined economic labels.

Red flags

  • A binding language that commits a tenant to a lease form without review rights
  • Undefined “fair market value” linked to future rent
  • Open-ended TI promises without a cap or scope definition
  • “Standard lease form” language without tenant review rights
  • Missing statement that the LOI is non-binding except for stated carve-outs

A tenant can reduce risk by following the process outlined in “How to Lease Commercial Space” before signing anything.

Frequently Asked Questions 

What is a commercial lease LOI?

A commercial lease LOI is a short, written outline of proposed business terms for a lease, used before attorneys draft the final agreement. A commercial lease LOI aligns rent, term, expenses, and key rights early to reduce misunderstandings.

Is a commercial lease LOI legally binding?

Most commercial lease LOIs are non-binding, but specific clauses may be binding if clearly stated. Common binding carve-outs include confidentiality, exclusivity, access, or expense reimbursement. Enforceability depends on the wording and the jurisdiction.

What terms should every commercial lease LOI include?

A commercial lease LOI should identify the landlord and tenant, describe the premises, state the rent and rent type, define the lease term, list renewal options, and set major conditions. Many LOIs also address permitted use and guaranty concepts when relevant.

What should you leave out of a commercial lease LOI?

A commercial lease LOI should avoid a full-lease-style legal drafting approach. Detailed default remedies, indemnity language, insurance schedules, and technical exhibits belong in the lease. The LOI should stay focused on business terms that drive cost and control.

Should an LOI include CAM, NNN, or operating expense terms?

A commercial lease LOI should state the operating expense structure, such as gross, modified gross, or NNN, and should note any expense estimates or cap concepts. Clear expense framing prevents “cheap rent” deals from becoming expensive through pass-through charges.

How should tenant improvements be handled in an LOI?

A commercial lease LOI should define TI as an allowance amount or a turnkey scope, and should state who controls the work and timing at a high level. The LOI should capture dollar amounts, scope intent, and delivery conditions, and leave construction details to the lease.

Who usually drafts the commercial lease LOI?

Either party can draft the LOI, but tenants often benefit from broker or attorney input to ensure that the business terms reflect actual costs and operational needs. Landlords may provide an initial LOI template, then the tenant counters with revisions.

How long should a commercial lease LOI be?

A commercial lease LOI should be short enough to remain negotiable but specific enough to prevent later retrading. Many effective LOIs fit on one to a few pages and use tables or bullets to cover economics, timing, and key rights.
