Gross-up (operating costs)
Adjusting variable operating costs as if the building were fuller, so tenants share costs fairly when it isn't fully leased.
For example: A tenant in a half-empty building asks how the lease handles gross-up. (Illustration only, not a real deal.)
This is a general industry term with no single official definition. Your lease or contract wording controls.
Example only, not a real client. Say you lease space in an office building that is only 60 percent full. Some costs, like cleaning, rise and fall with how many tenants are there. The landlord grosses those costs up as if the building were nearly full, so your share stays steady and you are not paying for empty floors.
What I’d tell a friend
A gross-up clause can protect you or cost you, depending on how it is written. Ask which costs it applies to and to what occupancy level.
Why it matters to you
It can make tenants pay costs as if the building were fuller than it is. Understand how it's applied before you agree.
How to use it in your deal
Tenants should check the occupancy level used, which costs are grossed up (only those that vary with occupancy), and how it interacts with any base year. Ask to see the calculation. Landlords should apply it consistently and explain it in reconciliations. Buyers should check gross-up practices since they affect recoveries.
The base year issue is where it bites: if your base year was grossed up and later years weren't, or the reverse, you may pay for increases that are really just the building filling up. Tenants should ask that the base year and every later year be grossed up the same way.
Landlords in a newly built building in Burnaby or Surrey leasing up over two or three years especially need a clear clause, since actual costs will rise as tenants move in. Owners preparing to sell should be able to show the gross-up working papers; a buyer's auditor will ask.
Mistakes I see
Grossing up fixed costs like insurance and property tax. Unclear occupancy level. Grossing up one year but not the base year. Not checking the math. Landlords collecting more than actual costs, which most leases don't allow.

What a gross-up does
A gross-up adjusts variable operating costs as if the building were fully or mostly occupied. Without it, tenants in a half-empty building could see their share swing as others move in and out.
It usually applies only to costs that change with occupancy, such as cleaning and some utilities, not to fixed costs like property tax or insurance.
What to check
Ask which costs are grossed up, the occupancy level used and whether the landlord recovers more than it actually spends. A fair gross-up spreads real costs; it should not create profit.
If your lease has a base year, ask that the base year be grossed up the same way, so your future increases are measured fairly.
Checking your statement this month
If you just got an additional rent or common area maintenance (CAM) statement or a year-end reconciliation, here is what I’d do with it:
- Find your share. Check the area the landlord used for you and for the whole building. Your share should match what the lease says.
- Ask for the backup. Request the year-end statement with a line-by-line breakdown and, for anything that jumped, the invoices behind it.
- Compare to last year. Line items that jump sharply deserve a question. So do new categories.
- Check the exclusions. Many leases exclude things like the landlord’s financing costs, leasing commissions, costs to fix construction defects, and capital work (or allow capital work only spread over its useful life). Look for any of those on your bill.
- Check the stop or base year. If your lease uses an expense stop or base year, you should pay only the increase above it, not the full amount.
- Check the gross-up and management fee. If the building was partly empty, see whether costs were grossed up and how. Check that the management or admin fee is the rate your lease allows, charged only on what it should be.
- Watch the deadline. Many leases give you a limited time to dispute a statement or ask to inspect the records. Read that clause first, and put your questions in writing before it runs out.
When to use audit rights: if the landlord’s answers don’t explain a large difference, or the same problem shows up year after year. Some leases make the landlord pay the audit cost if the overcharge is above a set percentage. Read your clause, and talk to a BC lawyer before you withhold anything.
Questions to ask before you sign
- What occupancy is used?
- Which costs are grossed up?
- Can I see the calculation?
Gross-up shifts vacancy onto occupied tenants
Gross-up bills operating costs as if the building were fuller. Example only: if heating would cost $60,000 full and $40,000 half-full, gross-up can make the occupied tenants cover more than the lights actually cost that year.
Tenants often try to strike or limit gross-up, and to add “reasonable” and “without duplication” to operating costs. Compare the reconciliation math to the lease, not to a summary PDF.
Audit rights matter more when gross-up is present.
