In a commercial lease, your rent is only part of what you pay. Operating expenses, the costs of running the building, are passed through to tenants in most lease structures, and they can add a substantial amount to your annual occupancy cost. What many tenants do not realize is that not every cost the landlord incurs should be in that pass-through. Operating expense exclusions are the lease provisions that keep unfair charges off your bill.
Negotiating exclusions is one of the highest-value activities in a commercial lease negotiation. Every dollar excluded from operating expenses is a dollar you never pay, year after year, for the entire lease term. This guide explains how operating expenses work, which exclusions matter most, and how to protect yourself from inflated pass-throughs.
How Operating Expense Pass-Throughs Work
Most commercial leases use one of three structures. In a triple net lease, the tenant pays base rent plus a share of taxes, insurance, and maintenance. In a modified gross lease, the tenant pays base rent plus operating expenses above a base year amount. In a full gross lease, the landlord covers operating expenses within the rent. The exclusion discussion matters most in the first two structures.
Your share of operating expenses is usually based on your proportionate share of the building, calculated by dividing your square footage by the building’s total rentable square footage. If you occupy 10 percent of the building, you pay 10 percent of the operating expenses. Simple in theory, but the definition of what counts as an operating expense is where the real money is.
Each year, the landlord provides a statement of actual operating expenses and reconciles them against the estimated payments you made monthly. If actual expenses exceeded the estimates, you owe the difference. If they came in lower, you get a credit. Your right to audit these statements is important, but exclusions are your first line of defense. Tenants watching their total occupancy cost should also read our guide on negotiating lower rent, since base rent and expenses interact.
Why Exclusions Matter So Much
Without exclusions, the operating expense definition in a landlord’s lease form is extremely broad. It typically includes every cost of operating, maintaining, and repairing the building, which gives the landlord wide latitude to pass through questionable charges. Exclusions narrow that definition and draw clear lines around what you will and will not pay for.
The financial impact compounds over time. An improper charge of $5,000 in year one, inflated by annual increases, can cost you tens of thousands over a ten year lease. Multiply that across several questionable categories and the numbers get serious. Exclusions are negotiated once but pay off every year.
Capital Expenditures
Capital expenditures, or capex, are the most important exclusion category. Capex covers major long-term investments like replacing the roof, repaving the parking lot, or installing a new HVAC system. These improvements benefit the landlord’s property for decades, so tenants argue they should not be passed through as annual operating costs.
Landlords often try to pass through capex by amortizing it, spreading the cost over the useful life of the improvement and charging tenants an annual slice. Your exclusion should address this directly. The strongest language excludes capital expenditures entirely. A common compromise excludes capex but allows amortization of specific items that reduce operating expenses, like energy-efficient lighting.
Pay special attention to the distinction between capital improvements and routine maintenance. Replacing a few worn carpet tiles is maintenance. Replacing the entire HVAC system is capital. Landlords sometimes blur this line, so your lease should define it. Ask for the landlord’s capitalization policy and reference it in the exclusion language.
Leasing and Marketing Costs
The costs of finding and keeping tenants should not be your burden. This category includes brokerage commissions, advertising, marketing expenses, and the cost of building out space for other tenants. Yet many landlord lease forms include these in operating expenses unless the tenant negotiates them out.
Tenant improvement allowances for other tenants are a particular concern. If the landlord spends $500,000 building out space for a new tenant, that cost should not appear in your operating expense statement. The exclusion should cover all costs of leasing space to others, including improvements, free rent given to other tenants, and lease buyout payments.
Management Fees and Related-Party Charges
Most leases allow the landlord to include a management fee in operating expenses, typically three to six percent of collected rents. This is standard, but it needs boundaries. Without a cap, the fee can grow unchecked, and without definition, it can overlap with other charges.
Negotiate a cap on the management fee, expressed as a percentage of gross rents actually collected. Also exclude management fees that duplicate other charges. If the landlord’s affiliate provides management services at above-market rates, you should not pay the markup. Require that all services from related parties be charged at competitive market rates.
Related-party transactions deserve a dedicated exclusion. Landlords sometimes hire affiliated companies for maintenance, security, or construction at inflated prices, then pass the costs to tenants. Your lease should require that all contracts with landlord affiliates be at rates no higher than what independent contractors would charge. This single provision can save you more than any other exclusion. Understanding the full cost picture starts with knowing which utilities tenants usually pay, since utility allocations interact with these management structures.
Costs Tied to Landlord Fault or Choice
You should not pay for the landlord’s mistakes or business decisions. This category covers a range of exclusions that sophisticated tenants always request. Fines and penalties incurred because the landlord violated laws or codes are the landlord’s responsibility, not yours.
Legal fees from disputes with other tenants, from the landlord’s financing activities, or from selling the building should be excluded. These are costs of the landlord’s business, not costs of operating the building for your benefit. The same applies to debt service: mortgage payments, loan fees, and refinancing costs are never operating expenses.
Insurance deductibles and uninsured losses are another battleground. If the landlord chooses a high deductible to lower premiums, the deductible amount should not be passed through to you when a claim occurs. Similarly, costs that insurance would have covered, had the landlord carried adequate coverage, should be excluded. You should only pay for the insurance the lease requires, not for the landlord’s coverage gaps.
Controllable vs Uncontrollable Expenses
Many leases cap the annual increase in controllable operating expenses, often at five percent per year. Controllable expenses are costs the landlord can manage, like maintenance, landscaping, and management fees. Uncontrollable expenses, like taxes, insurance, and utilities, are usually excluded from the cap.
The cap is only as good as the definitions behind it. Make sure the lease clearly defines which expenses are controllable, and make sure your exclusions apply before the cap is calculated. A cap on inflated expenses still leaves you overpaying. Negotiate the exclusions first, then the cap.
Also confirm whether the cap is cumulative or non-cumulative. A non-cumulative cap limits each year’s increase independently, which is better for tenants. A cumulative cap lets the landlord bank unused increases and apply them later. This technical detail can make a large difference over a long lease term.
Audit Rights: Enforcing Your Exclusions
Exclusions are worthless without the right to verify compliance. Your lease should give you the right to audit the landlord’s operating expense records at least once a year. The audit right should cover the books and records behind the annual statement, not just the statement itself.
Negotiate the audit mechanics in advance. You should be able to use an auditor of your choice, including one who works on contingency, since contingency auditors have strong incentives to find overcharges. The landlord will push for limits, such as requiring audits within a set time after receiving the statement. Ninety to 180 days is typical, so calendar the deadline.
Include a penalty for material overcharges. A common provision requires the landlord to pay your audit costs if the audit reveals an overcharge above a threshold, such as five percent. This gives the landlord a financial incentive to keep the statements honest. Without it, landlords face little downside from aggressive expense reporting.
Before signing, make sure your exclusion list and your audit right work together. The exclusions define what cannot be charged, and the audit right lets you verify it. One without the other is incomplete. And as with every lease provision, the time to get this right is before you sign, which is why reading the lease before signing with an eye on expenses pays for itself many times over.
