A gross-up provision requires the landlord to adjust the operating expense reconciliation to reflect what expenses would have been if the building were 95%–100% occupied, rather than the actual occupancy level during the measurement year. It prevents tenants from being overcharged for variable expenses (such as cleaning, utilities, and security) during periods of high vacancy when those expenses are artificially low relative to a fully occupied building.

Without a gross-up provision, a tenant in a 60% occupied building in year one pays a proportionate share of operating expenses based on actual low-occupancy costs. When the building fills to 95% occupancy in year two, actual expenses increase significantly - but the tenant's base year (set during low occupancy) remains understated, causing the tenant to owe large pass-through amounts above the understated base. The gross-up provision eliminates this timing distortion by normalizing expenses to full occupancy conditions for comparison purposes in all years.
Require gross-up to apply to all variable operating expenses - specifically cleaning, utilities, security, and management fees - but not to fixed expenses like insurance premiums, real estate taxes, and debt service, which do not vary with occupancy. Specify the gross-up occupancy threshold in the lease, often 95% of rentable area in negotiated office leases, so the landlord cannot use a lower threshold that provides less protection. Apply the gross-up provision to both the base year and all subsequent years to maintain a consistent comparison standard throughout the lease term.

Gross-up of variable expenses only at 95% occupancy, gross-up applied to all operating expenses including fixed items (occasionally negotiated), gross-up limited to the base year only, and no gross-up provision (most landlord-favorable, flagged as a red flag by Lextract).
Lextract extracts these fields directly from your lease PDF when this clause is present:
Base Year Clause
A base year clause establishes a reference year - typically the first full calendar year of the lease term - against which future operating expense increases are measured.
Operating Expense Stop
An operating expense stop is a lease provision that sets a maximum dollar threshold for operating expenses included in the base rent - the landlord bears all operating costs up to the stop amount, and the tenant is responsible for any expenses above that threshold.
Rent Escalation Clause
A rent escalation clause is a lease provision that provides a predetermined mechanism for increasing the base rent over the lease term.
A gross-up provision adjusts operating expenses to reflect what costs would have been if the building were 95% to 100% occupied, rather than the actual occupancy level. It normalizes variable expenses - cleaning, utilities, security, management fees - that fluctuate with occupancy. The adjustment applies to both the base year and all subsequent years, maintaining a consistent comparison standard. Fixed expenses like insurance and taxes, which do not vary with occupancy, are excluded from the gross-up calculation.
A 95% gross-up threshold is common in negotiated office leases. Tenants should resist landlord attempts to use a lower threshold (such as 80%) that provides less protection. The gross-up should apply only to variable operating expenses - cleaning, utilities, security, and management fees - but not to fixed expenses like insurance premiums, real estate taxes, and debt service. Applying gross-up to both the base year and all subsequent years ensures consistent comparisons throughout the lease term.
When occupancy drops to 60%, actual variable expenses decrease because fewer tenants generate less cleaning, utility, and security demand. Without a gross-up, the tenant's pro-rata share of these lower actual expenses would be used as the comparison point. When occupancy later recovers, expenses rise - but the base year figure remains understated, creating inflated pass-throughs. The gross-up provision normalizes expenses to 95% occupancy in both periods, ensuring the tenant pays only for genuine cost increases rather than occupancy-driven fluctuations.
