What is a gross-up provision in a commercial lease?

A gross-up provision allows a landlord to normalize variable CAM expenses as if the building were at a specified occupancy level (usually 90 or 95 percent). This prevents tenants from bearing a disproportionate share of expenses when the building has vacant space.

What makes a gross-up a violation?

Three common violations: (1) grossing up fixed costs that do not vary with occupancy, such as insurance or security; (2) using the wrong occupancy threshold in the gross-up formula; (3) applying a gross-up when the lease does not authorize one at all.

How do I check for a gross-up violation from the reconciliation statement?

Request the expense detail and look for a gross-up adjustment line or a note in the reconciliation. Then check the lease to confirm the authorized occupancy threshold and which expense categories are eligible for gross-up.

Can a gross-up violation affect the management fee?

Yes. If the management fee is calculated as a percentage of grossed-up CAM expenses, and the gross-up was applied incorrectly, the management fee base is also inflated. Both the gross-up error and the downstream management fee overcharge need to be corrected.

What is the dollar impact of a typical gross-up violation?

It depends on building size and occupancy. For a tenant occupying 5,000 square feet in a 50,000 square foot building at 75% occupancy, applying a gross-up to fixed costs that should not be grossed up can add thousands of dollars to the annual CAM bill.

Gross-Up Violations: What They Are and How They Show Up in the Books

Gross-Up Provision: A lease clause that allows the landlord to normalize certain variable CAM expenses as if the building were occupied at a specified threshold, typically 90 to 95 percent of leasable area. The intent is to ensure tenants pay their proportionate share of occupancy-sensitive costs, even when the building has vacant space that depresses actual usage. When applied correctly, it is a reasonable fairness mechanism. When applied to the wrong expenses, or when the occupancy threshold is misstated, it becomes a source of overcharging.

Gross-up clauses are some of the hardest clauses in a lease. That is where overcharges hide. CAM means Common Area Maintenance. Accounting teams see these numbers on the reconciliation statement. A reconciliation is the landlord's yearly bill that trues up CAM charges. The numbers arrive with no backstory. No one knows where they came from or if they are fair. For more, see CAM red flags accounting firms track.

You need to know three things. How gross-up works. What a bad one looks like. How to check it against the lease abstract. Get those right and you code an accurate charge. Miss them and you approve an inflated one.

How gross-up works in practice

Some CAM costs change with use. These are variable costs. Think HVAC, cleaning, and power for common areas. When a building is 60 percent full, these costs run lower than at 95 percent full.

Without a gross-up clause, a tenant in a 60 percent full building pays too much. The math splits costs by occupied space, and that base is small. A gross-up clause fixes this. It scales variable costs up to a set occupancy level.

Here is the math. Say variable CAM costs are $120,000 at 60 percent full. The lease allows gross-up to 95 percent. Divide $120,000 by 60 percent. Then multiply by 95 percent. That equals $190,000. The tenant's pro-rata share applies to $190,000, not $120,000. Pro-rata share is the tenant's slice of the total, based on its square footage.

That is the clause doing its job. The problem starts when it hits costs that do not change with use.

What a Violation Looks Like

Grossing up fixed costs

Fixed costs do not change with occupancy. Property insurance is the clearest case. A landlord pays the same premium at 60 percent full or 100 percent full. The same goes for security monitoring fees, some admin costs, and structural upkeep contracts. These cover the whole building no matter who is in it.

When a landlord grosses up these fixed costs, the tenant pays too much. The insurance premium does not rise when the building scales to 95 percent. But the tenant's charge does.

Take a dental practice in a 40,000 square foot medical building. Say insurance is a $7,800 pass-through. The landlord grosses it up from 70 percent to 95 percent. The tenant's share goes up. The real insurance cost did not move. That gap is a flat overcharge.

Wrong occupancy level

Many leases name the exact occupancy level for the gross-up math. Say the lease says 95 percent but the landlord uses 90 percent. The scale-up comes in too low. That pushes more of the real cost onto current tenants.

Now flip it. The lease says 90 percent but the landlord uses 95 percent. The scale-up goes too far. Costs rise past what the lease allows.

The check is simple. Open the lease abstract. Find the gross-up occupancy level. Compare it to the percent used on the reconciliation. If they do not match, you found a violation.

Gross-up applied with no authorization

Some leases have no gross-up clause at all. Then the landlord cannot scale up variable costs. If the reconciliation shows a gross-up and the lease allows none, the whole gross-up is wrong.

This happens more than it should. Property managers use template reconciliations that assume a gross-up. So the line shows up for a building that never negotiated one. No one checks the lease, so no one catches it.

How to check gross-up against the lease abstract

The lease abstract should capture three things about gross-up. Does a clause exist? What occupancy level does it allow? Which cost types qualify? If the abstract skips these, it is not complete for this job.

When a CAM reconciliation shows a gross-up, work this order:

Step 1: Confirm the lease has a gross-up clause. If the abstract does not name one, pull the CAM section of the lease and look for gross-up language.

Step 2: Find the occupancy level the lease allows. It is usually a set percent in the gross-up clause.

Step 3: Ask the landlord for the cost detail. Find which lines were grossed up.

Step 4: Match each grossed-up cost to the lease's eligible list. Any fixed cost in that set is a likely violation.

Step 5: Check the occupancy percent used in the math against the lease level. Ask for the building's real occupancy for that period.

Our tool flags gross-up violations. It checks if the occupancy level matches the lease. It checks if the grossed-up cost types match the lease too. In tests on published audit cases, this rule caught overcharges that summary statements hide.

What it costs

Three things drive the dollar impact. How much ineligible cost got grossed up. The gap between real occupancy and the gross-up level. The tenant's pro-rata share.

Here is a simple case. A building has $40,000 in fixed insurance. Real occupancy is 70 percent. The lease allows gross-up for variable costs only. The landlord grosses up the insurance from 70 percent to 95 percent. The grossed-up amount is $40,000 divided by 70 percent times 95 percent, which equals $54,286. The tenant's 12.5 percent share of that is $6,786. The correct charge is $5,000, their share of the fixed $40,000 premium. The overcharge is $1,786 on this one line.

Now scale that to a full reconciliation with several fixed costs grossed up. The number climbs fast.

How it hits management fees

Gross-up errors get worse when the management fee is a percent of grossed-up CAM costs. Say the fee is 4 percent of the CAM pool. A gross-up violation inflates that pool. So the fee inflates too.

Take a tenant with a $1,200 per month management fee. A gross-up violation inflates the CAM pool by $20,000. The fee overcharge is about $1,500 per year. Both errors must reverse if the gross-up is challenged.

When a review finds a gross-up violation, flag two things. Flag the gross-up. Flag any management fee built on the inflated base.

What to do when you find one

First, put a number on it. Work out the correct charge. Use gross-up only on eligible variable costs, at the right occupancy level. Compare that to what was billed.

Next, write it all down. Note the lease clause, the allowed level, the costs wrongly grossed up, and the dollar impact. This is the base for a dispute if the client wants one.

The dispute itself is not accounting work. A bookkeeper or controller who finds a gross-up violation should show the client. Then advise sending it to a lease auditor or the client's lawyer. Your job is to find and size the gap. The fix path belongs to the client.

"Gross-up violations are almost never intentional. Property managers use standardized reconciliation templates that apply gross-up across all expense categories. Checking the eligible categories against the lease is the step that almost never happens without a formal review." - Angel Campa, Founder of CAMAudit

Build the check into your workflow

When a reconciliation has a gross-up line, add two steps. Confirm the lease allows a gross-up. Confirm the eligible cost types match what the landlord used.

Neither step takes long if the lease abstract is current. If it is not, update the abstract to capture the gross-up clause. Do it before the next reconciliation cycle.

Firms with many NNN lease clients should use one abstract template. Make gross-up fields required captures. NNN means the tenant pays its share of building costs on top of rent. Skip those fields at abstraction time and you find the gap during close week. That is the worst time to go back to the lease.
