Operating expense cap
Also called: expense stop, controllable expense cap, CAM cap
An operating expense cap limits how much a tenant's share of operating costs can rise year over year, typically stated as a percentage such as 5 percent. Caps almost always apply only to controllable expenses, carving out taxes, insurance, utilities, and snow removal, which the landlord cannot influence.
A cap converts an open ended obligation into a budgetable one. Without it, a tenant on a ten year triple net lease has signed up for an unknown number, and the only limit on that number is what the landlord chooses to spend.
Cumulative versus non cumulative, which matters more than the percentage
This distinction is worth more than a point or two on the cap rate itself.
- Non cumulative: each year's increase is capped at the stated percentage over the prior year's actual. A year of low spending permanently lowers the base for every subsequent year.
- Cumulative: unused headroom carries forward. If the cap is 5 percent and costs rise 2 percent in year one, year two may rise 8 percent. Over a ten year term a cumulative cap can allow nearly all of the increase an uncapped lease would.
- Cumulative and compounding: the most landlord favorable version, where the cap is applied to a compounded base rather than to actuals.
A landlord redline that changes one word from "non cumulative" to "cumulative" is a small edit with a large number attached, and it is exactly the kind of change that gets lost in a long round.
The controllable carve out
Most caps exclude taxes, insurance, utilities, and snow removal. That carve out is standard and generally reasonable, but the list grows in landlord drafts. Security, management fees, and "costs required by law" are the three that migrate into the uncontrollable bucket most often, and each is arguably within the landlord's control.
What a market cap looks like
Retail and industrial deals commonly land at 4 to 6 percent non cumulative on controllable expenses. Office deals in base year structures often use a different mechanism entirely, capping the increase on the tenant's share above the base year stop. Small tenants get caps less often than large ones, which makes it worth asking for early in the letter of intent rather than raising it for the first time in the lease.

CAM charges are the tenant's proportionate share of the cost of operating and maintaining a property's shared areas, billed monthly as an estimate and trued up against actual spend after the year closes.
A CAM reconciliation is the annual statement in which a landlord compares the estimated common area maintenance payments a tenant made during the year against the property's actual operating costs, then bills or credits the difference.
A triple net lease is a commercial lease in which the tenant pays base rent plus its proportionate share of three operating costs: property taxes, building insurance, and common area maintenance.
A base year is the calendar year whose operating expenses are built into a tenant's base rent, so the tenant pays only its share of increases above that year's costs.
A letter of intent is a short document setting out the principal business terms of a proposed lease — space, term, rent, allowance, and options — before either side spends money on a full lease draft.
