Gross-Up %

The assumed occupancy level used to extrapolate variable operating expenses.

Also known as: Gross-Up Provision

By Angel Campa, Founder · Updated March 2026

Why This Field Matters

Without a gross-up provision, existing tenants in a partially occupied building subsidize the vacant space. If a building is only 60% occupied but tenants pay pro rata shares of actual expenses, each tenant effectively pays 167% of their fair share. A gross-up to 95% occupancy normalizes expenses to reflect a stabilized building, preventing cost spikes as vacancies fluctuate.

Where to Find It in Your Lease

Found in the "Operating Expenses" or "Additional Rent" section. Look for language about "adjusting expenses as if the building were X% occupied" or "gross-up to 95% occupancy." May also be in a definitions section.

How Lextract Extracts This Field

The AI searches for the field name and common aliases like "Gross-Up Provision" across all pages of the document, then assigns a confidence score based on OCR quality and extraction certainty.

Frequently Asked Questions

What does gross-up mean in a commercial lease?

Gross-up adjusts variable operating expenses to reflect what they would be if the building were at a specified occupancy level (typically 95%). This prevents tenants from absorbing costs attributable to vacant space. Only variable expenses (like utilities and janitorial) are grossed up; fixed costs (like insurance and taxes) are not.

What is a typical gross-up percentage?

The standard gross-up assumes 95% occupancy, meaning variable expenses are calculated as if 95% of the building were occupied. Some leases use 100%, but 95% is the market standard because even fully leased buildings maintain some operational vacancy.
