At 2:40 on a Thursday afternoon, the power goes out in a dental office on the third floor of a mid-rise building. The chairs stop. The compressor falls silent. A patient with half a crown prepped sits up and looks at the dentist. Over the next nine days, the practice cancels forty appointments. When the owner opens the lease to ask what the landlord owes for this, she finds one sentence. It says the landlord is not liable for any interruption of utilities, and that rent continues without abatement.

That sentence was in the lease the day she signed. It sat in the part of the document most tenants skim, because utilities feel like the least dramatic topic in a lease. They are not. A utilities clause quietly decides two things: how much you pay for electricity, water and heat, and what you're owed when they stop.

The two halves of a utilities clause

Most commercial leases handle utilities in two separate places, and tenants tend to read neither carefully.

The first half is billing. It says who contracts with the utility company, how consumption is measured, and what you pay the landlord for services the landlord provides.

The second half is interruption. It says what happens when a service fails, and it is almost always written to protect the landlord.

The two halves together create an odd arrangement. You may pay a calculated share for a service you can't verify, and you may have no remedy when it isn't delivered.

How you get billed: three models that behave very differently

Direct metering. The space has its own meter, and you have your own account with the utility. This is the cleanest model. The utility sends you a bill based on measured use, under tariffs regulated by a public utility commission. The landlord is out of the middle.

Submetering. The building has one master meter, and the landlord installs private meters on each space. The landlord pays the utility and then bills you for your reading. Here the lease controls the details. Does the landlord bill at its actual cost, or at a rate it sets? Can it add an administrative fee? Who maintains and calibrates the submeter, and what happens when it's wrong? Many states regulate resale of utilities in some way, but the rules vary widely and often exempt commercial settings. Don't assume a regulator is checking the landlord's math.

Allocation formulas. If there are no meters, the landlord divides the building's utility bill using a formula, typically your share of the square footage. This is sometimes called ratio utility billing. It's convenient for the landlord and indifferent to how you actually use the space. A tenant who runs a quiet office and a tenant who runs refrigeration may pay in proportion to floor area, not consumption. Or the reverse may happen, if the clause lets the landlord adjust the formula for heavy users.

None of these is automatically unfair. The problem is that the lease often doesn't say which one applies until a bill arrives.

Where utility costs hide

A utilities clause rarely lives alone. Look for these in the surrounding text:

  • Utilities folded into operating expenses. Common-area electricity and water may show up inside CAM or operating expense charges, which means you can be billed for utilities twice, once for your space and once as a share of the building's.
  • After-hours HVAC. Base rent typically covers heating and cooling only during stated business hours. Outside those hours you pay an hourly rate. If the clause says the rate is "as determined by Landlord," that number can change without a negotiation.
  • Excess consumption. Many leases let the landlord charge extra, or require you to install a dedicated meter, if your usage exceeds what a normal tenant would use. Who decides what is normal is usually the landlord, sometimes by engineer's survey at your cost.
  • Service fees. Some leases add a percentage on top of passed-through utility costs for billing and administration. Compare this against any administrative fee already charged elsewhere in the lease.

The interruption clause: what the law lets the landlord write

The typical language has three parts: the landlord may interrupt services for repairs or other causes, the landlord is not liable for the interruption, and the tenant is not entitled to abatement of rent. Courts in many places enforce this as written, because commercial leases are treated as agreements between sophisticated parties, not consumer contracts.

That is a sharp contrast with residential law. Many states imply a warranty of habitability for homes, which gives residential tenants remedies when basic services fail. Commercial tenants generally get no equivalent protection. What they get is what the lease says, plus a few common-law doctrines that are hard to use.

The main doctrine is constructive eviction. If the landlord's failure makes the premises unusable, the tenant may treat the lease as ended and stop paying rent. But the standard is demanding. The failure usually has to be substantial and caused by the landlord. The tenant generally has to give notice and a chance to fix it, and then actually leave within a reasonable time. A tenant who stays in the space while claiming it's uninhabitable can lose the argument. That's why the doctrine is a bad plan for a dental practice that needs the location and can't move overnight. Exact requirements differ by state.

The other limit is the language itself. Courts often read exculpatory clauses narrowly. A clause that excuses interruptions for "repairs" may not excuse an outage caused by the landlord's own neglect or deliberate shutoff. But a narrow reading is an argument you make after you've already lost nine days of revenue.

What good language looks like

Tenants can negotiate here, especially before signing. The terms worth asking for:

  1. Rent abatement after a grace period. For example, rent stops if an interruption caused by the landlord lasts a set number of consecutive business days.
  2. A termination right if the interruption lasts far longer, so you aren't locked into paying for unusable space.
  3. Billing at actual cost. No markup, with the landlord's utility bills available on request.
  4. A submeter standard. Meters that are accurate, tested on request, and corrected retroactively if they're found faulty.
  5. A defined after-hours rate, either a figure or a formula tied to the landlord's actual cost.
  6. Notice before planned shutoffs, with work scheduled outside your operating hours where possible.

If you run a business that can't tolerate downtime, such as medical, food service, data, or lab space, also ask whether the building has backup power and who pays to run it.

Your next moves

  • Find every utilities reference in your lease today. Search for "utilities," "electricity," "HVAC," "submeter," "interruption," and "services." Highlight each hit, since they are often scattered across several sections.
  • Identify your billing model. Write one line: direct, submetered, or allocated. If the lease doesn't say, email the landlord and ask in writing.
  • Request the backup. Ask for the landlord's underlying utility bills and your submeter readings for the last twelve months. Compare your charge to the landlord's actual cost per unit.
  • Check for double counting. Compare your utility charges against your operating expense statement to see whether common-area utilities appear in both.
  • Read the interruption sentence for a number. Look for any day count, abatement trigger, or termination right. If there's none, note that your remedy for an outage is currently zero, and decide whether it's worth raising at renewal.
  • Check your business interruption insurance. Ask your broker whether it covers loss of income from a utility outage at the building, including outages that start off your premises.

The part nobody reads until it matters

A utilities clause feels like administrative filler right up until a bill looks wrong or a switch stops working. By then, the leverage you had at signing is gone.

That is the problem closeout was built around. It reads a commercial lease and pulls out the clauses that carry quiet cost or quiet risk, utilities and service-interruption language among them, so you can see them in plain terms before a dispute begins.
