Le'Toya Garland signed a lease for a hip-hop dance studio in an industrial park in Aurora, Colorado, with common area fees listed at $300 to $500 a month. By mid-2024, her landlord had tripled that number to $1,693 and handed her a $9,000 bill for back-charges no one had told her to expect. The price on the flyer was never the price.
"We would not have signed the lease if we had known," Garland said. Her studio sits in an industrial park with no shared lobby and no communal space. The charges came anyway. What happened to Garland is not a story about one bad landlord. It is a story about how the standard commercial lease is built.
The Advice That Fails the System
"Compare the price per square foot." That is the line every tenant hears. Every broker says it. It sounds right. It is not.
A 2026 Tower Corp analysis found that hidden costs in a typical commercial lease add 20 to 40 percent on top of base rent. Take a space listed at $20 per square foot. Once you add common area charges, tax pass-throughs, insurance, and escalation clauses, the true cost lands near $37.56. That is not a rounding error. That is a different lease.
A JLL study found that 74 percent of tenants said they lacked a full breakdown of how their common area charges were built. Three out of four could not see the math behind the bill. "Compare the price per square foot" does not fail the tenant's intent. It fails the system the tenant is trying to run.
The Flaw Is Not the Landlord
There is a name for this in the literature. It is called information asymmetry. Brokers and landlords model the full cost of a space: base rent plus operating costs plus tax adjustments plus insurance plus escalation plus gross-up provisions. Tenants compare one number on a flyer.
The problem is not that landlords hide the charges. The problem is that sticker price replaces total cost as the basis for the decision. Every cost that sits outside the listed rate becomes a surprise. And the lease is built to hold more of those surprises than most tenants think to look for.
Two devices do the most damage.
The first is the escalation clause. A 3 percent annual bump sounds small. Over a ten-year lease, it compounds to 34 percent above the starting rent. On a 5,000-square-foot space at $28 per square foot, that adds $24,000 a year by year five alone.
The second is the gross-up provision. This one is quiet and hard to spot. It lets the landlord charge common area fees as if the building were full, even when it is not. If a building sits at 60 percent occupied, the tenant still pays a share based on 100 percent. The vacancy cost shifts to the people who stayed.
What to Build Instead
The better principle is plain: model the total cost of the space before you sign. Not the rate per square foot. The full number, every year, through the end of the term. Once that is clear, three moves follow from it.
Move 1: Request the Full Operating Expense History
Ask the landlord for three years of actual operating costs. Not estimates. Not pro forma projections. The real bills. Common area charges, taxes, insurance, and every fee passed through to tenants. If the landlord will not share them, that tells you more than the flyer ever would.
This is the step most tenants skip. It takes effort. It means asking for records the landlord has no reason to hand over gladly. That friction is the point.
Move 2: Model the Escalation Forward
Take the base rent and apply the escalation clause to every year of the lease. Write down the number for year one. Then year three. Then year five. Then year ten. Most tenants never do this. They sign based on the starting number and absorb the rest as it comes. The math is not hard. The habit of running it is.
Move 3: Hire Tenant-Side Representation
A tenant rep works for you, not the landlord. In most deals, their fee comes out of the landlord's commission split, so it costs the tenant nothing out of pocket. Published estimates put the savings from tenant representation at 10 to 25 percent of total occupancy cost over a five-year term. On a six-figure lease, that is not a small edge.
What the Model Shows You
Running this before you sign does something the old advice never did. It shows which costs are fixed and which the landlord can adjust at will. It shows how the year-ten number compares to year one. It shows whether the space you think you can afford is the space you can actually hold for the full term. And it shows, in hard numbers, the gap between what was listed and what you would actually pay.
Three Questions for the Next Lease
At the end of the modeling process, ask three things.
→ Which line items moved the total cost the most?
→ Which parts of the listed rate looked like savings but added cost later?
→ Where did the landlord have room to adjust charges without your approval?
That is the gap between advice that sounds right and a system that proves itself.
Where This Leaves You
Le'Toya Garland said she would not have signed if she had known. Most tenants who get surprised say the same thing after it is too late. The numbers were always in the lease. They were just not on the flyer. The real price of a space is the one you find when you build the spreadsheet yourself.
