A commercial lease is the contract that governs a business tenant’s right to occupy space for retail, office, industrial, or other income-generating use, and unlike a residential lease it operates almost entirely on freedom of contract. Courts treat business tenants as sophisticated parties who negotiate their own terms, so the specific language on the page carries more weight than any default rule you might expect the law to supply. That makes what you sign one of the most consequential financial decisions a business owner faces, and it makes each of the sections below worth reading before you initial anything.
How the Lease Structure Decides Who Pays What
The structure sets who covers property taxes, insurance, maintenance, and utilities on top of your base rent. Getting it wrong can add tens of thousands of dollars a year to occupancy costs, and it’s the negotiation where tenants most often quietly lose money for years.
Gross and Modified Gross Leases
A gross lease, sometimes called a full-service lease, bundles everything into one monthly payment. The landlord pays property taxes, building insurance, utilities, and maintenance out of that amount. Landlords price gross leases higher to absorb the risk that those costs rise, but the predictability is why small businesses and startups often prefer them.
A modified gross lease splits the difference. The landlord typically pays all operating expenses during a “base year,” and the tenant picks up its proportional share of any increases above that baseline in later years. If property taxes jump 8% in year two, you pay your share of that increase.
Net and Triple Net Leases
Net leases shift specific expense categories from landlord to tenant. A single net lease adds property taxes to your base rent. A double net lease adds property taxes and building insurance. A triple net lease, written as NNN, pushes taxes, insurance, and common area maintenance to the tenant, making it the fullest transfer of operating costs. In an NNN structure, the landlord takes a predictable net income stream and you absorb the risk that any of those three categories climbs.
Common area maintenance (CAM) covers shared expenses such as parking lot repairs, lobby cleaning, landscaping, and snow removal. Depending on the property, CAM can add several dollars per square foot annually on top of base rent.
Percentage Rent in Retail
Retail tenants in shopping centers and malls often see percentage rent clauses. You pay base rent plus a percentage of gross sales once revenue crosses a threshold called the breakpoint. The natural breakpoint equals annual base rent divided by the agreed percentage. If your base rent is $60,000 and the rate is 6%, your breakpoint is $1,000,000, and you pay 6% only on sales above that line. Some leases use an artificial breakpoint, a flat figure the parties negotiate independent of base rent.
Percentage rent gives the landlord a stake in your success, which is why it usually travels with a continuous operation clause requiring you to stay open during set hours and maintain minimum inventory. Violating that clause can trigger a default even when your rent is current, because the landlord’s percentage income depends on the store actually generating sales.
The Clauses That Carry the Most Money and Risk
A commercial lease has dozens of provisions. A handful of them decide most of the financial and legal exposure, and those are worth spending negotiating capital and legal fees to get right.
Permitted Use
This clause defines exactly what business activities you can conduct in the space. A landlord might limit you to “specialty coffee retail” rather than a broader “food and beverage” designation, and that distinction matters if you later want to add a lunch menu or pivot the concept. Violating the use clause can trigger termination or a court order to stop the unauthorized activity. Push for language broad enough to accommodate reasonable business evolution, while recognizing that landlords restrict use to protect zoning compliance and avoid conflicts with other tenants.
Term, Commencement, and Holdover
The lease usually spells out two dates: the commencement date, when you get access, and the rent commencement date, when rent starts. The gap between them is your free-rent build-out window.
The holdover provision is one of the most expensive clauses tenants overlook. Stay past expiration without a signed renewal, and most leases impose holdover rent of 120% to 200% of the rent that was in effect at the end of the term. That penalty compounds fast when renewal talks run long. Start renewal discussions months before expiration.
Rent Escalation
Escalation clauses control how base rent rises over the term. Fixed-percentage bumps, commonly 2% to 4% per year, give certainty. Consumer Price Index adjustments track inflation and can produce unpredictable jumps in volatile periods. Some leases combine the two, with CPI subject to a floor and a cap. Check whether escalation applies to base rent only or to your full occupancy cost including operating expense shares.
Exclusivity
An exclusivity clause prevents the landlord from leasing other space in the same property to a direct competitor. A bakery tenant might block the landlord from renting to another bakery within the shopping center. These clauses matter most in multi-tenant retail where being the only option of your type is part of the location’s value.
Maintenance and Repair
Maintenance splits are a frequent source of disputes. Landlords typically handle structural elements (roof, foundation, exterior walls) and tenants cover interior repairs. HVAC sits in a gray area worth calling out in the lease. Routine tasks like filter changes and thermostat issues usually fall on the tenant. Major repairs to compressors, coils, or ductwork are typically the landlord’s, and full unit replacement is generally treated as a capital expense the landlord bears. But “typically” and “usually” are doing a lot of work in those sentences. If the lease says otherwise, the lease controls. Get HVAC allocation written out.
Force Majeure
A force majeure clause addresses what happens when extraordinary events outside either party’s control prevent performance. These clauses traditionally covered natural disasters, wars, and labor disputes. After COVID-19 exposed gaps in many leases, the provisions now often address pandemics, government-mandated shutdowns, and public health emergencies directly. A force majeure event does not automatically excuse rent. Courts have held that economic difficulty or reduced revenue alone does not qualify. The clause must list the type of event, and most require that performance be impossible, not merely unprofitable.
Estoppel Certificates
Most commercial leases require the tenant to sign an estoppel certificate on request, usually when the landlord is selling the building or refinancing. The certificate confirms current lease status for a third party, verifying that rent is current and disclosing any claims you have against the landlord. Refusing to sign is generally a default, so review the estoppel language carefully and make sure the certificate calls for factual confirmations, not waivers of rights.
Assignment, Subletting, and Recapture
Almost every commercial lease restricts your ability to transfer the space. An assignment transfers your entire leasehold interest to a new tenant. A sublease transfers part of the space or part of the remaining term while keeping you on the hook under the original lease. Both typically require the landlord’s prior written consent.
The critical question is the consent standard. Some leases allow the landlord to withhold consent “in their sole discretion,” which is effectively a veto for any reason. Others require that consent “shall not be unreasonably withheld, conditioned, or delayed,” which gives you meaningful protection if the landlord blocks a qualified replacement without justification. If your lease uses the sole-discretion standard, negotiate it to a reasonableness standard before you sign. A business that needs to relocate, downsize, or close before expiration will be trapped if the landlord can kill every sublease attempt.
Watch also for recapture clauses, which let the landlord take back the space rather than consent to an assignment. If you’ve built a profitable location and want to sell the business with the lease attached, recapture can blow up the deal.
Personal Guarantees and How to Limit Them
When the business entity is new, thinly capitalized, or lacks strong credit, landlords ask the owner to personally guarantee the lease. A full personal guarantee makes you individually liable for every dollar owed under the lease for the entire term. If the business fails three years into a ten-year lease, the landlord can pursue you personally for the remaining seven years of rent.
That exposure is worth negotiating down. Several alternatives exist:
- A burndown provision reduces your personal liability over time, often eliminating it entirely after one to two years of on-time payments. Burndowns can apply to personal or corporate guarantees.
- A limited guarantee caps your liability at a set dollar amount, such as three years of rent or the landlord’s total investment in tenant improvements and leasing commissions.
- A good guy guarantee ends your personal liability as long as you surrender the space properly, meaning adequate written notice (typically 30 to 90 days), rent paid through the surrender date, and the space returned in acceptable condition. Miss any of those and the landlord can pursue you for the full breach.
- A performance-based release lifts the guarantee once the business hits agreed revenue or profitability benchmarks.
Landlords have little reason to renegotiate after signing, so push these during initial negotiations. If the landlord insists on a full guarantee, at minimum build in a burndown tied to payment history.
Tenant Improvements and Build-Out
Most commercial spaces need modification before a new tenant can operate. A tenant improvement (TI) allowance is money the landlord contributes toward customizing the space, expressed as a dollar amount per rentable square foot. In competitive markets, Class A office buildings may offer $40 to $60 per square foot for creditworthy tenants on long-term leases, while Class B buildings in secondary markets may offer $15 to $30. Retail TI allowances typically run $10 to $30 per square foot for inline space, with anchor tenants sometimes receiving more.
TI allowances generally cover “hard costs” like walls, flooring, ceiling work, and electrical or HVAC modifications. Some landlords also cover “soft costs” such as architectural drawings and permits. Furniture, IT cabling, security systems, and moving usually sit outside the allowance. If the space needs only minor updates, you may be able to apply unused TI toward rent abatement or building system upgrades.
A TI allowance is not free money. Landlords recoup it through higher base rent over the term. A generous allowance paired with a long lease can cost more than a smaller allowance with a shorter commitment. Run total occupancy cost over the full term before celebrating the TI number.
Operating Expenses and Your Audit Right
Under any net lease structure, you pay estimated monthly amounts for your share of operating expenses, and the landlord reconciles actual expenses against those payments after year end. CAM reconciliation statements are typically due 30 to 90 days after December 31, and they almost always result in the tenant owing additional money rather than getting a refund.
Negotiate an audit right into the lease. That lets you review the landlord’s books and verify the charges match what the landlord actually spent and what the lease requires you to pay. Good audit language also lets you reopen prior-year reconciliations if you find a recurring error. Without audit rights, you’re trusting the landlord’s accounting, and in multi-tenant buildings with complex shared expenses, errors are common.
Watch for CAM exclusions. Well-negotiated leases exclude capital improvements, costs of leasing vacant space, management fees above a stated percentage, and expenses caused by the landlord’s negligence. If capital improvements can be passed through as CAM, the landlord can effectively make tenants fund upgrades that primarily raise the property’s value.
SNDAs When the Landlord Has a Mortgage
A subordination, non-disturbance, and attornment agreement (SNDA) is a three-way agreement among you, the landlord, and the landlord’s lender. It addresses what happens to your lease if the landlord defaults on its mortgage and the bank forecloses. Without an SNDA, commercial tenants have few statutory protections, and a bank taking over the building could theoretically terminate the lease and evict you.
The non-disturbance piece is what protects you: the lender agrees your lease survives foreclosure and you won’t be evicted as long as you’re not in default. The attornment piece is your side of the bargain: you recognize the new owner as your landlord and keep performing. If the landlord carries mortgage debt on the property, request an SNDA before or shortly after signing. It seems academic until it matters, and when it matters, it matters enormously.
ADA Compliance Falls on You Too
Under the Americans with Disabilities Act, anyone who owns, leases, or operates a place of public accommodation must ensure equal access to goods and services. If you run a restaurant, retail store, medical office, hotel, or similar business open to the public, Title III applies to you directly as the operator, regardless of what the lease says about who handles building modifications.
For existing facilities, Title III requires you to remove architectural barriers where doing so is “readily achievable,” meaning without significant difficulty or expense. When barrier removal is not readily achievable, you must provide access through alternative methods where feasible. For any alterations you make, the altered areas and the path of travel to them must be accessible to individuals with disabilities to the maximum extent feasible. New construction must be readily accessible from the start. Buildings under three stories or with fewer than 3,000 square feet per story are exempt from the elevator requirement, unless the building is a shopping center, shopping mall, or healthcare provider’s office.
The lease should clearly allocate ADA responsibilities between landlord and tenant. If it doesn’t, both parties can face liability. Negotiate who pays for what and get it in writing.
Insurance Requirements
Commercial leases impose specific insurance obligations that go well beyond what most business owners expect. At minimum, you’ll need a commercial general liability (CGL) policy on an occurrence basis. Typical limits for retail and office tenants range from $1 million to $5 million, with larger or higher-risk operations sometimes required to carry $10 million or more. The landlord will almost certainly require you to name them as an additional insured on every liability policy, meaning your insurer covers the landlord for claims arising from your operations.
You’ll also need property insurance covering your personal property, inventory, and any improvements you’ve made. The lease typically specifies replacement cost (which ignores depreciation) or actual cash value (which deducts it). Replacement cost is more expensive but pays out more when you claim. Some landlords now also require cyber liability coverage, particularly for tenants that handle customer payment data.
Applications, Deposits, and the LOI
Landlords vet commercial tenants far more rigorously than residential ones. Expect to provide at least two to three years of business tax returns showing profitability, plus current financial statements (balance sheet and profit and loss). Startups substitute a detailed business plan with revenue projections. For small LLCs and sole proprietorships, the landlord will also request the owner’s personal financial statements and credit report. A personal credit score below 650 often triggers a larger security deposit or a personal guarantee.
The application asks for your business’s registered legal entity name and federal Employer Identification Number, plus three to five trade references and previous landlord contacts. Commercial security deposits generally have no statutory cap; landlords commonly ask for one to three months’ rent depending on credit profile. A bank-issued letter of credit can sometimes substitute for a cash deposit and preserve working capital.
Negotiations usually start with a Letter of Intent outlining the key business terms: rent, term length, TI allowance, and permitted use. The LOI is generally non-binding on its substantive deal terms, but that word “generally” deserves respect. Confidentiality and exclusivity periods within an LOI are almost always intended to bind. Where the LOI requires good-faith negotiation, courts in many jurisdictions take that seriously. Practically, every term in the LOI becomes the baseline for the lease draft, and a term you failed to include becomes much harder to negotiate into the final document.
Once the landlord’s attorney drafts the full lease from the LOI, have your own attorney review it. Commercial leases routinely contain indemnification clauses, insurance requirements, default triggers, and remedies the LOI never mentioned. The landlord’s draft is written to protect the landlord. Your attorney’s job is to rebalance it.
Renewal Options
A renewal option gives you the right, but not the obligation, to extend for an additional term. Rent for the renewal is set in one of two ways. Some options lock in a fixed rate, which helps if the market has risen. Others reset rent to fair market value at the time of renewal, determined through a process the lease describes, sometimes involving brokers or appraisers from both sides. If your option uses fair market value, start the process well before the deadline; you’ll want time to research comparable rents and negotiate, ideally with a commercial broker who knows the market.
A renewal option is not an automatic right to stay. Miss the option deadline, often six to twelve months before expiration, and you lose the right entirely. Calendar the deadline the day you sign the lease, not the month it comes due.
Default, Remedies, and Getting Out Early
What Counts as a Default
Failing to pay rent is the most common default, but commercial leases define default broadly. Violating the permitted use clause, letting required insurance lapse, making unauthorized alterations, and breaching assignment restrictions can all trigger default. Most leases include a cure period, typically 3 to 30 days depending on the violation type and jurisdiction, during which you can fix the problem before the landlord pursues further remedies. Monetary defaults usually have shorter cure periods than non-monetary ones.
What the Landlord Can Do
If you don’t cure, the landlord’s remedies can be severe. Rent acceleration clauses allow the landlord to demand the entire remaining rent in a single payment. Courts will enforce these as liquidated damages, but only if the amount bears a reasonable relationship to the anticipated loss. A clause that lets the landlord collect accelerated rent from you while also collecting full rent from a replacement tenant is likely unenforceable as a penalty, because the landlord cannot recover the same loss twice.
Beyond acceleration, landlords can pursue forfeiture of your security deposit, eviction, and damages for lost rent and re-leasing costs. In most jurisdictions the landlord has a duty to mitigate by making reasonable efforts to find a replacement tenant, meaning advertising the space, listing it, and showing it to prospects. The landlord is not required to accept a replacement willing to pay significantly below market.
Exit Strategies Before the Term Ends
Some leases include an early termination clause that lets you exit before the term ends in exchange for a fee, commonly one to three months’ rent. Without one, your options are more limited and more expensive. You can negotiate a lease buyout, typically a lump sum compensating the landlord for lost rent and re-leasing costs. Or you can try to assign the lease or find a subtenant, subject to the transfer restrictions above.
Walking away without a negotiated exit exposes you to the full range of default remedies: accelerated rent, deposit forfeiture, and, where a personal guarantee is in place, a claim against the business owner individually. Before signing a long-term lease, think seriously about what happens if the business doesn’t work at that location. An early termination clause costs bargaining power going in, and it can save you from catastrophic liability later.
