What expenses are typically subject to gross-up?

Variable expenses that scale with occupancy are subject to gross-up: janitorial, utilities for common areas, HVAC, and similar costs. Fixed expenses like insurance premiums, property taxes, and management fees typically do not qualify for gross-up because they do not decrease when a building is partially vacant.

What is the typical gross-up threshold in commercial leases?

The most common threshold is 95% occupancy. If occupancy falls below 95%, the landlord must normalize variable expenses as if the building were 95% occupied before allocating them to tenants. Some leases use 90% or 100%, so the actual threshold in your lease controls.

Why does the gross-up provision exist?

Without gross-up, tenants in partially occupied buildings pay a disproportionately high share of variable expenses. If half the building is vacant, janitorial and utility costs do not decrease by 50%, but each occupied tenant's share would increase under a simple pro-rata calculation. Gross-up corrects for this distortion by normalizing costs to a full-occupancy baseline before allocating.

Does CAMAudit calculate the exact dollar amount of a gross-up overcharge?

CAMAudit identifies whether gross-up was applied and flags missing adjustments. Calculating the precise dollar overcharge requires the landlord's detailed internal cost allocation data, which tenants typically obtain during a formal audit. CAMAudit's finding gives you the documented basis for requesting that audit and specifying which expense categories are at issue.

Gross-Up Violation: How Vacancies in Your Building Can Inflate Your CAM Bill

If your building had vacancies and your landlord failed to gross up variable expenses as your lease requires, the missing adjustment can inflate each occupied tenant's share by 15% or more of the variable expense pool.

Definition

Gross-Up Violation

A gross-up violation occurs when a landlord fails to normalize variable CAM expenses to a defined occupancy level, typically 95%, when actual occupancy falls below that threshold. Gross-up provisions exist to protect tenants from bearing a disproportionate share of variable operating costs caused by the landlord's own vacancies. Without a gross-up adjustment, expenses that naturally decrease as occupancy drops, such as janitorial, common area utilities, and HVAC, are allocated across fewer tenants at their actual reduced cost rather than at what they would be at full occupancy, which effectively increases each tenant's share above what was intended. CAMAudit's gross-up detection rule extracts the occupancy threshold and the list of expense categories subject to normalization from the lease, checks the actual occupancy level reported in the reconciliation period, and flags any variable expense categories where the gross-up adjustment is absent when it should have been applied.

How CAMAudit Detects This

CAMAudit extracts the gross-up provision from your lease, including the occupancy threshold, commonly 95%, the categories of expenses subject to gross-up, and the formula for normalization. Not all leases include gross-up provisions, and CAMAudit notes when one is absent so you understand whether this protection applies to you.

CAMAudit's gross-up detection rule checks the occupancy level during the reconciliation period against the threshold when a gross-up provision is present. When occupancy was below the threshold, gross-up should have been applied to variable expenses. CAMAudit reviews whether the reconciliation statement includes gross-up adjustments and flags the discrepancy when they are missing.

CAMAudit notes in the finding report which variable expense categories were affected and estimates the scale of the missing adjustment based on the occupancy gap. CAMAudit's finding gives you the documented basis for a formal audit request, since the landlord's internal cost allocation data is needed to calculate the precise dollar impact of the missing normalization.

Real-World Example

A tenant's lease required gross-up of variable expenses to 95% occupancy when actual occupancy fell below that level. During the audit year, the building was 78% occupied. Total variable expenses (janitorial, common area utilities, HVAC) were $84,000. Without gross-up, each tenant paid based on 78% occupancy. Grossed up to 95%, the pool should have been normalized to $102,308 before allocation ($84,000 divided by 0.78, multiplied by 0.95). The landlord allocated $84,000 without adjustment. CAMAudit flagged the missing gross-up on $84,000 in variable expenses and noted that the formal audit would determine each tenant's specific overcharge based on the internal cost split.
