No, most commercial leases do not automatically include utilities in the base rent. The tenant usually pays for electricity, gas, water, sewer, trash, internet, and sometimes HVAC maintenance on top of the monthly rent, unless the lease is a true “full-service gross” lease where the landlord bundles those costs into a single price.
The core problem is the Uniform Commercial Code and common-law contract rules that treat a commercial lease as a negotiated private contract between two sophisticated parties, meaning courts will enforce whatever the lease says โ even if it is unfair to the tenant. When a lease is silent or ambiguous about utilities, the tenant often ends up paying thousands of dollars in unexpected pass-through charges, and the U.S. Small Business Administration warns that occupancy costs are one of the top three reasons small businesses fail in their first five years. According to the 2025 BOMA Experience Exchange Report, utilities account for roughly 19 to 24 percent of total operating expenses in a typical U.S. office building, which means a tenant who assumes rent is “all-in” can face annual surprise bills of \$3.50 to \$6.00 per square foot.

The Core Question: Who Pays for Utilities in a Commercial Lease?
The answer depends entirely on the lease type, the clause language, and the building’s metering setup. In U.S. commercial real estate, there is no federal statute that forces a landlord to include utilities in rent, and the Restatement (Second) of Property: Landlord and Tenant gives both parties wide freedom to negotiate who pays what. This freedom is called freedom of contract, and it is the single most important legal principle in commercial leasing.
When a landlord drafts a lease, the landlord decides whether to bundle utilities into the base rent or to pass them through as a separate charge. The tenant’s only protection is the lease language itself, because unlike residential tenants, commercial tenants do not enjoy the implied warranty of habitability under most state laws, as confirmed in cases like Wesson v. Leone Enterprises in Massachusetts and similar rulings across the country.
The consequence of ignoring the utility clause is severe. A tenant who signs a triple-net lease without reading the operating-expense section can owe the landlord tens of thousands of dollars per year in reconciliation charges. The common misconception is that “rent” means “everything” โ it almost never does in a commercial setting.
Why Utilities Are Treated Differently Than Residential
Residential leases in most states fall under state landlord-tenant acts and the Uniform Residential Landlord and Tenant Act (URLTA), which often require the landlord to maintain essential services like heat, hot water, and electricity. Commercial tenants do not get this protection, because courts assume business tenants hire lawyers and brokers to review lease terms.
The consequence is that a commercial landlord can legally shift nearly every utility cost to the tenant, including electricity used by common-area hallways, parking lot lighting, and even the landlord’s management office. This practice is called gross-up, and it is governed by the building’s operating expense clause rather than by any statute.
A real-world example makes this clear. When Maria Chen opened her boutique bakery in a Dallas strip mall in 2024, she assumed her \$3,200 monthly rent covered water for her sinks. Her landlord later billed her \$4,800 for her prorated share of the shopping center’s water bill because the center had one master meter. Maria had no legal recourse because the lease contained a standard NNN pass-through clause.
The Role of Building Metering
Buildings fall into three metering categories: directly metered, submetered, and master metered. A directly metered space has its own utility meter read by the local utility company, and the tenant pays the utility directly. A submetered space has a private meter installed by the landlord, who bills the tenant based on actual usage. A master-metered building has one meter for the entire property, and the landlord allocates costs by square footage or another formula.
The Federal Energy Regulatory Commission does not regulate most submetering, but state public utility commissions do. For example, the California Public Utilities Commission requires submetered tenants to be charged no more than the utility’s tariff rate, and violating this rule can trigger fines under California Public Utilities Code Section 2705.5.
The consequence of master metering is that a small tenant can subsidize a larger neighbor’s heavy use. A common misconception is that “prorated by square footage” is fair โ it rarely is, because a restaurant uses five to ten times the water and electricity per square foot of a law office.
The Five Major Commercial Lease Types and How They Handle Utilities
Commercial leases fall into five main categories, and each treats utilities differently. Understanding these categories is the foundation of every negotiation.
Full-Service Gross (FSG) Lease
A full-service gross lease bundles rent, utilities, janitorial, property taxes, insurance, and common-area maintenance into one flat monthly payment. This lease type is most common in Class A office towers in cities like New York, Chicago, and San Francisco, where landlords want to simplify the tenant experience. The tenant pays one check and the landlord handles everything, as described by the Building Owners and Managers Association.
The consequence of signing an FSG lease is that the tenant loses visibility into actual utility costs. If the tenant runs server rooms or stays open 24 hours, the landlord will likely include a “base year” or “expense stop” clause that passes through any utility cost above the first-year baseline.
A real example helps. James Rodriguez, a fintech CEO, signed a 10,000-square-foot FSG lease at \$55 per square foot in a Manhattan tower in 2025. His base year set utility costs at \$8.20 per square foot. In 2026, when Con Edison rates rose 14 percent, James received a supplemental bill of \$11,480 for his share of the overage, which is permitted under the New York Real Property Law governing commercial leases.
The common misconception is that “full service” means “all-inclusive forever.” It does not โ it means all-inclusive in the base year only.
Modified Gross Lease
A modified gross lease splits the utility burden. Typically, the landlord pays for water, sewer, trash, and common-area electricity, while the tenant pays directly for in-suite electricity, gas, internet, and telephone. This structure is popular in suburban office parks and medical office buildings across Texas, Florida, and Georgia.
The consequence of a modified gross lease is that the tenant must budget separately for direct utility accounts. Tenants often forget to transfer service into their business name at move-in, which can trigger a landlord default notice under the standard AIR CRE commercial lease form used in California.
Priya Patel, a dentist in Atlanta, signed a modified gross lease for her practice in 2023. The lease required her to pay Georgia Power directly for her suite. She missed the transfer deadline, the landlord kept the account open for 45 days, and Priya was billed \$2,200 for electricity she did not supervise. Her lease allowed the landlord to charge a 15 percent administrative markup under Georgia Code ยง 44-7-50.
The common misconception is that “modified” means “flexible.” It means the opposite โ the split is fixed in the lease and rarely negotiable after signing.
Triple Net (NNN) Lease
A triple net lease makes the tenant responsible for base rent plus property taxes, building insurance, and common area maintenance (CAM). Utilities in a NNN lease are almost always the tenant’s sole responsibility, either through direct metering or through submetered pass-throughs. NNN leases dominate retail strip centers, freestanding fast-food pads, and industrial warehouses, as documented by the International Council of Shopping Centers.
The consequence of a NNN lease is total cost transparency โ but also total cost exposure. If the local utility raises rates, the tenant absorbs 100 percent of the increase. There is no cap unless the tenant negotiates one.
David Kim, who franchises three smoothie shops in Phoenix, signed NNN leases with a \$3.75 per square foot CAM estimate in 2024. When Arizona Public Service raised commercial electricity rates by 9.4 percent in 2025 under an approved Arizona Corporation Commission tariff, David’s CAM reconciliation came in at \$5.10 per square foot, costing him an extra \$8,100 across three stores.
The common misconception is that NNN rent is “cheaper.” The base rent is lower, but total occupancy cost is often higher than a comparable gross lease.
Absolute Net (Bondable) Lease
An absolute net lease, sometimes called a bondable lease, pushes every cost โ including roof, structure, and utilities โ onto the tenant. These leases are used for single-tenant credit properties like Walgreens, Dollar General, and FedEx distribution centers, and they are analyzed in detail by Net Lease Advisor.
The consequence is that the tenant becomes the de facto property owner for operational purposes. If a transformer fails, the tenant pays. If the water main breaks, the tenant pays.
Percentage Lease
A percentage lease charges a base rent plus a percentage of gross sales above a breakpoint. Percentage leases are common in regional malls and are often paired with a modified gross structure for utilities, where the landlord pays for common-area lighting and HVAC but the tenant pays for in-store electricity through a submeter. The Institute of Real Estate Management publishes annual benchmarks for percentage-lease utility allocations.
Utility Pass-Through Clauses: The Fine Print That Costs Tenants Thousands
Pass-through clauses are the single biggest source of utility-related disputes in commercial real estate. These clauses allow the landlord to bill the tenant for a share of building-wide costs, and they are governed by the lease’s operating-expense definition.
Operating Expense Definitions
The operating-expense definition is a long list of costs the landlord can pass through. A well-drafted tenant clause excludes items like capital improvements, landlord’s financing costs, marketing, and leasing commissions, as recommended by the American Bar Association’s Real Property section.
The consequence of a broad operating-expense definition is that the landlord can pass through replacement of a 30-year-old chiller as a “utility expense,” even though it is really a capital improvement. A tenant should always demand that capital items be amortized over their useful life under GAAP standards.
Gross-Up Provisions
A gross-up provision lets the landlord calculate variable operating expenses โ especially utilities โ as if the building were 95 percent occupied, even when it is only 70 percent occupied. This protects the landlord from absorbing fixed-cost underpayments during vacancy.
The consequence for the tenant is that gross-up can inflate utility bills by 10 to 25 percent in a half-empty building. A savvy tenant negotiates a gross-up cap at 95 percent and requires the landlord to apply the gross-up only to variable costs like electricity and cleaning, not fixed costs like property taxes, following guidance from the Institute of Real Estate Management.
Sophia Williams, a marketing agency owner in Denver, discovered in 2025 that her landlord had grossed up her building’s utilities at 100 percent occupancy when the building was only 62 percent leased. She recovered \$14,600 in overpayments after her attorney invoked the lease’s audit clause, which is standard under Colorado Revised Statutes ยง 38-12-103.
Audit Rights
Audit rights let the tenant inspect the landlord’s books to verify pass-through charges. Most leases cap the audit window at 90 to 180 days after the annual reconciliation statement.
The consequence of missing the audit deadline is that the tenant waives the right to challenge the charges, even if they are wrong. Courts have repeatedly enforced these waivers, as in Plaza Freeway Ltd. Partnership v. First Mountain Bank.
Three Popular Scenarios: How Utility Clauses Play Out in Real Life
The following scenarios reflect the three most common fact patterns tenants encounter.
Scenario 1: The Restaurant in a Strip Mall
| Tenant Action | Financial Outcome |
|---|---|
| Signs NNN lease without reading utility clause | Pays prorated share of shared water bill at restaurant-level usage |
| Fails to install a private submeter for kitchen | Subsidizes low-use neighbors for three years |
| Discovers \$18,000 annual overpayment | Negotiates submeter installation in lease renewal |
Scenario 2: The Coworking Space in a Class A Tower
| Tenant Action | Financial Outcome |
|---|---|
| Signs FSG lease with 2024 base year | Enjoys flat utility cost in year one |
| Extends hours to 24/7 operation | Triggers after-hours HVAC surcharge at \$65 per hour |
| Fails to cap base-year gross-up | Absorbs 18 percent utility overage in year three |
Scenario 3: The Warehouse Distribution Center
| Tenant Action | Financial Outcome |
|---|---|
| Signs absolute net lease on single-tenant pad | Takes full responsibility for all utilities |
| Installs solar panels without landlord consent | Violates lease alterations clause |
| Negotiates utility cap in renewal | Saves \$42,000 per year on electricity |
Federal and State Laws Governing Commercial Utility Billing
Federal and state laws create a patchwork of rules that affect how landlords can bill utilities.
Federal Framework
At the federal level, the Public Utility Regulatory Policies Act (PURPA) encourages submetering but does not mandate it. The Energy Policy Act of 2005 created tax incentives for energy-efficient commercial buildings under IRS Section 179D.
The consequence of the 179D deduction is that landlords who install LED lighting and high-efficiency HVAC can claim up to \$5.65 per square foot in tax deductions, which they often use to justify higher utility pass-throughs even when the tenant sees no savings. A common misconception is that energy upgrades automatically lower tenant bills โ they do not, unless the lease requires the landlord to share savings.
State Disclosure Laws
Several states require commercial landlords to disclose utility usage data. California Assembly Bill 802 requires buildings over 50,000 square feet to report annual energy use to the California Energy Commission. New York City Local Law 97 imposes carbon caps on buildings over 25,000 square feet starting in 2026, with penalties of \$268 per metric ton of CO2 over the cap.
The consequence of Local Law 97 is that New York City landlords are passing compliance costs through to tenants as a new line item called “sustainability surcharge.” Tenants in pre-2024 leases are fighting these charges under the lease’s exclusions clause.
Submetering Rules by State
Texas allows submetering under Texas Water Code Chapter 13 but caps the landlord’s markup at the utility’s published rate. Florida permits submetering under Florida Statutes ยง 83.535 for water and electricity. Illinois restricts submetering under the Illinois Tenant Utility Payment Disclosure Act.
The consequence of violating state submetering law is civil liability, including treble damages in some states, as shown in Graham v. Kim and similar California cases.
Mistakes to Avoid
Tenants consistently make the same utility mistakes. Avoiding them saves money and prevents disputes.
Assuming rent is all-inclusive. A tenant who skips the utility clause often faces \$3 to \$6 per square foot in surprise charges. The negative outcome is a blown operating budget in year one.
Skipping the audit clause. Without audit rights, the tenant cannot verify landlord charges. The negative outcome is overpayment that compounds for the full lease term.
Ignoring the gross-up provision. A 100 percent gross-up in a half-empty building inflates bills by 20 percent or more. The negative outcome is subsidizing vacant space.
Not submetering high-use operations. Restaurants, data centers, and medical offices use far more utilities per square foot than neighbors. The negative outcome is cross-subsidization.
Missing the utility transfer deadline. A tenant who forgets to transfer service pays the landlord’s inflated administrative rate. The negative outcome is a 10 to 20 percent markup.
Failing to cap after-hours HVAC charges. After-hours rates of \$50 to \$100 per hour can destroy a 24/7 business model. The negative outcome is erosion of margins.
Overlooking the base-year definition. An artificially low base year inflates future pass-throughs. The negative outcome is escalating charges every year.
Ignoring capital-improvement exclusions. A broad operating-expense definition lets landlords pass through chillers and roofs as utilities. The negative outcome is a six-figure surprise.
Not reading the force majeure clause. A utility outage caused by a storm may not trigger rent abatement. The negative outcome is paying full rent for unusable space.
Do’s and Don’ts of Commercial Utility Negotiation
Do request a copy of the prior year’s utility bills before signing, because CCIM Institute research shows that tenants who review historical data negotiate 8 percent lower occupancy costs.
Do negotiate a gross-up cap at 95 percent occupancy, because this protects you from landlord vacancy exposure.
Do insist on a 180-day audit window, because 90 days is often too short to hire a lease auditor.
Do require capital improvements to be amortized, because this prevents one-time hits.
Do install submeters when your usage exceeds 150 percent of the building average, because this isolates your true cost.
Don’t sign a lease that bundles utilities with property taxes, because this hides tax increases inside utility charges.
Don’t accept “market rate” language without a definition, because this gives the landlord unlimited pricing power.
Don’t skip the force majeure review, because utility outages are increasingly common due to climate events.
Don’t assume the broker represents you, because most commercial brokers are dual agents under state law, including Texas Occupations Code ยง 1101.558.
Don’t waive consequential damages without a mutual waiver, because this leaves you exposed while the landlord is protected.
Pros and Cons of Each Utility Structure
Pros of Full-Service Gross: Predictable budgeting for year one, single point of contact for repairs, landlord incentive to maintain efficient systems, simplified accounting, and easier cash flow forecasting.
Pros of Triple Net: Full cost transparency, direct control over usage, lower base rent, tax deductibility of operating costs under IRS Publication 535, and ability to install tenant-owned efficiency upgrades.
Cons of Full-Service Gross: Higher base rent, hidden base-year manipulation, limited cost control, gross-up exposure, and difficulty comparing buildings on a true cost basis.
Cons of Triple Net: Unlimited exposure to rate increases, capital-improvement pass-throughs, administrative burden of multiple utility accounts, higher audit costs, and complex reconciliation statements.
Pros of Modified Gross: Balanced risk allocation, direct tenant control over in-suite usage, landlord control over common areas, easier negotiation leverage, and lower administrative complexity than NNN.

In Trizec Properties v. Superior Court, California confirmed that gross-up provisions are enforceable when written clearly but must be applied consistently across tenants.
FAQs
Are utilities always separate from commercial rent?
No. Full-service gross leases bundle utilities into rent during the base year. Most other lease types โ modified gross, NNN, and absolute net โ charge utilities separately from base rent.
Can a landlord charge more than the utility company charges?
No. Most state public utility commissions, including California and Texas, prohibit landlords from marking up submetered utility charges above the published tariff rate.
Do I have to pay for common-area utilities?
Yes. In NNN and modified gross leases, tenants pay a prorated share of common-area electricity, water, and HVAC through CAM charges, usually allocated by square footage.
Can I audit my landlord’s utility charges?
Yes. If the lease contains an audit clause, tenants can inspect the landlord’s books within the stated window, typically 90 to 180 days after the annual reconciliation.
Is after-hours HVAC extra?
Yes. Most office leases charge \$35 to \$100 per hour for HVAC outside standard business hours, and this fee is separate from base rent and CAM.
Are utility caps negotiable?
Yes. Tenants with strong credit or large footprints can negotiate annual caps on utility pass-throughs, typically in the 5 to 7 percent range year-over-year.
Can my landlord shut off my utilities for late rent?
No. Most states prohibit utility shutoffs as a self-help remedy, even in commercial leases, under common-law rules against wrongful eviction.
Does force majeure cover utility outages?
No. Standard force majeure clauses rarely trigger rent abatement for short utility outages, though extended outages may qualify under specific lease language.
Can I install solar panels on a leased building?
No. Without landlord consent and a lease alterations amendment, installing solar panels violates the lease and can trigger default under most commercial forms.
Do I pay utilities during the build-out period?
Yes. Unless the lease provides a free-rent period that explicitly includes utilities, tenants pay for construction electricity and water starting at lease commencement.
Are utility costs tax deductible?
Yes. Commercial utility payments are ordinary business expenses deductible under IRS Section 162, as explained in IRS Publication 535.
Can my landlord change the utility allocation method?
No. Once the lease is signed, the landlord cannot unilaterally change how utilities are allocated unless the lease reserves that right in writing.
