At AQUILA, our property management and leasing teams have worked with hundreds of tenants to help them understand the terms of their commercial lease. It is important that our tenants understand the terms of their lease and know what their rental rate is going towards.

A common clause in many commercial leases, especially triple net office leases, is a gross up provision.

We know that understanding what a gross up provision is, and why it is necessary, can be confusing.

In this article we will explain:

  • Exactly what a gross up provision is
  • How gross up provisions can help both landlords and tenants

Background Information: Understanding Op/Ex

Before we dive into what a gross up provision is, it is important to have a basic understanding of operating expenses, since these are what gross up provisions relate to.

So what are operating expenses?

Operating expenses are the costs associated with operating and maintaining a commercial property. In double net and triple net leases, tenants are required to reimburse landlords for a portion of the building’s overall operating expenses.

In a multi-tenant building, each tenant usually pays their proportionate share of these operating expenses, based on the size of their lease relative to the total square footage of the building.

Operating expenses consist of:

Some of these expenses, including taxes and insurance, are fixed no matter the occupancy rate of the building. Other costs, like janitorial service, janitorial supplies, trash, electricity, water and management fees, vary based on how much of the building is occupied.

Exactly which expenses are considered variable should be listed in your lease.

So, what is a gross up provision?

Simply stated, the concept of “gross up provision” stipulates that if a building has significant vacancy, the landlord can estimate what the variable operating expense would have been had the building been fully occupied, and charge the tenants their pro-rata share of that cost.

The gross up provision only applies to variable expenses, because these are incurred directly as a result of the tenant(s) occupying the building.

Fixed expenses are not a part of the gross up, because the costs remain the same with or without tenants, and the landlord is obligated to pay those expenses regardless of the building’s occupancy.

A helpful example…

Imagine a 10-story office building with 10,000 square feet per floor, totaling 100,000 square feet.

If the building has five different tenants, each occupying one floor, each tenant’s proportionate share would be 10% (1/10 of the total building).  


Table Showing Gross Up Example


Let’s say that the landlord’s annual operating expenses for the building are $100,000, with $75,000 going towards fixed expenses, and $25,000 going towards expenses that vary with occupancy.


Gross Up Expenses Equation


If there was not a gross up provision in the lease, each tenant would pay its pro-rata share of the $100,000 operating expenses: $10,000 ($7,500 for fixed expenses and $2,500 for expenses that do vary by occupancy).


Gross Up Table Showing Opex Example


But when the landlord collects the $10,000 from each tenant, they would only receive $12,500 total to put towards the variable operating expenses ($2,500 x 5), which is only one-half of the total $25,000 in variable operating expenses that the landlord actually incurred.

If there is a gross up provision in the lease, the landlord can project what the variable operating expense would be at full occupancy. Because at 50% occupancy the variable expenses are $25,000, he can estimate that at 100% occupancy, the variable expenses will be $50,000.

This grossed-up variable expense, plus the fixed expense, now brings the total operating expense to $125,000. Each tenant will pay $12,500, with $7,500 going towards fixed expenses and $5,000 going towards variable expenses. At this rate, the full $25,000 variable expense is covered ($5,000 x 5).

Why do landlords use gross up provisions?

A gross up provision allows the landlord to preserve his income stream and cover the actual costs to operate the property despite below average occupancy.

When there is high vacancy in a property, the landlord becomes responsible for whatever portion of fixed expenses the tenants are not covering in their operating expenses. In the example above, the landlord would have paid $37,500 in fixed expenses, because only half of the $75,000 total fixed expenses were covered by the tenants’ op/ex ($7,500 x 5).

In the example above without the gross up provision, the landlord would have also been responsible for the $12,500 gap between collected variable operating expenses and the total variable expenses.

This variable expenses was only incurred because the tenant was occupying the building. If the tenant wasn’t there, there would be no need for janitorial services, the air conditioning could be turned down, and the water and electric usage would be dramatically less.

In essence, without a gross up provision, it actually cost the landlord in our example money to have tenants in the building.

The gross up provision ensures that the tenants cover any operating expenses incurred because of their occupancy.

When do gross up provisions help tenants?

Tenants will see two primary benefits by having a gross up provision in their lease.

First, it allows for predictable budgeting. Without a gross up provision, operating expenses could vary drastically year to year, making predicting annual real estate expenses a nightmare.

Second, if operating expenses are based on a base year, the gross up provision can protect the tenant from a big spike in their share of operating expenses.

To explain this second point, let’s consider another example.

Say a tenant moves into a new building that is only partially occupied, with a lease that doesn’t contain a gross-up clause.

If the tenant pays operating expenses based on a base year amount and the base year operating expenses are low due to low occupancy, then when the building becomes fully occupied in later years, the tenant’s pro-rata share of operating expenses will experience a significant jump.

This is because the landlord passes through to the tenant any operating expenses that exceed the predetermined base year amount, and the operating expenses will surely increase as occupancy increases.

By having a gross up provision in the lease, the tenant is protected from a this risk because the base year will have used estimated fully occupied rates.


Are gross up provisions negotiable?

The short answer is yes.

The terms of a gross up provision can and should be negotiated and outlined in your lease. The two points of negotiation are:

  • At what occupancy the gross up provision can be enforced. Typically, a gross up provision will kick in when the average occupancy for the year falls below 80%.
  • What occupancy rate the expenses can be grossed up to. In our examples, we assumed 100%. However, this can range between 95 or 100%.

However, whether you have a gross up provision or not is nonnegotiable. They are simply a fact of nearly all commercial triple net leases, to protect both the landlord and the tenant.


Hopefully, you now understand exactly what a gross up provision is and why it is a crucial detail in any commercial lease.
