What are the most common types of CAM overcharges?

CAMAudit checks 14 overcharge categories. The most common: management fee overcharges (landlord bills above the lease cap), pro-rata share errors (wrong denominator inflates your percentage), CAM cap violations (annual increase exceeds the contractual cap), gross-up violations (landlord applies gross-up to fixed expenses or uses wrong occupancy threshold), and common area misclassification (capital expenditures billed as operating expenses).

How can I check if I am being overcharged without paying an auditor?

Start by pulling your lease and reading three sections: the CAM definition clause (what expenses can be included), the exclusions clause (what cannot be included), and the pro-rata share definition. Then compare your reconciliation line items against those lists. For anything math-dependent — management fee caps, pro-rata percentages, CAM growth caps — you need to run the actual calculations. CAMAudit's free scan runs those calculations automatically against your uploaded documents, at no charge for the initial findings summary.

What documents do I need to gather before investigating a CAM overcharge?

You need two sets of documents: (1) Your commercial lease, specifically the sections defining CAM expenses, exclusions, management fee caps, pro-rata share, and any CAM cap or base year provisions. (2) Your annual CAM reconciliation statement from your landlord — the year-end document that shows actual expenses billed and reconciles against your estimated monthly payments. If you have multiple years of reconciliations, gather the most recent one first.

What should I do if a CAM overcharge is confirmed?

The sequence that works: First, document the discrepancy in writing. Most leases have a dispute window — typically 90 to 180 days after the landlord delivers the reconciliation — and you need a written objection within that window or you may waive the right to challenge. Second, send a formal dispute letter citing the specific lease provision and the dollar amount. Third, exercise your audit rights if your lease includes them — most commercial leases give tenants the right to inspect the landlord's supporting records. CAMAudit generates the dispute letter draft as part of every paid audit report.

Can I check for overcharges without involving an attorney?

Yes, for the initial investigation. Running the math against your lease and sending a written objection are tenant-side activities that do not require an attorney. Many overcharges are resolved through direct negotiation after a tenant presents documented findings. For larger disputes, contested lease interpretation questions, or cases where the landlord refuses to correct a clear error, legal counsel is worth considering — but starting with documentation is the right first step.

Find Out If Your Landlord Is Overcharging You on CAM

Something looks off in your CAM reconciliation — the management fee seems high, a line item appeared this year that wasn't there before, or the total jumped in a way that doesn't match anything in your lease. The only way to know for certain is to run the math against your actual lease terms. Here's what to look for first.

6 Signs You May Be Overcharged on CAM

None of these signs confirm an overcharge on their own — they confirm that a calculation is worth running. Suspicion is not evidence; the lease math is.

Your management fee percentage seems high
Most commercial leases cap the management fee at 3–5% of gross revenues or total operating expenses. If your reconciliation shows a management fee approaching or exceeding that range, or if the fee is growing faster than total CAM expenses, that warrants a check against your lease cap provision.
Your pro-rata share is higher than neighboring tenants report
If other tenants in your building or center mention paying a lower CAM pro-rata share than you are, this can signal a denominator problem. Landlords sometimes use a smaller gross leasable area (GLA) figure than your lease specifies, or exclude anchor tenant space that your lease says should be included — both of which inflate your share.
CAM charges are growing faster than inflation year over year
CAM charges that consistently outpace CPI by a large margin — especially on controllable expenses — often indicate that CAM cap provisions are not being applied correctly. Many leases cap annual increases in controllable expenses at 3–5% per year. If your CAM grew 15% last year, check whether a cap applies.
New line items appeared on your reconciliation this year
Landlords occasionally add new expense categories to CAM reconciliations over time — capital improvement reserves, landlord administrative fees, green building certification costs. Each new line item should be checked against your lease's CAM definition and exclusion list to determine whether it's a permitted pass-through.
Your CAM charges increased sharply after a major renovation or new tenant move-in
Capital improvements — roof replacements, HVAC system upgrades, parking lot repaving — are frequently excluded from CAM under commercial leases. If CAM spiked after a major project, the landlord may be amortizing capital costs through the CAM pool instead of absorbing them.
Your true-up payment was significantly larger than estimated
A consistently large true-up each year — where actual CAM far exceeds your estimated monthly payments — can indicate that your estimates are being deliberately suppressed, or that the reconciliation arithmetic itself contains an error in the landlord's favor.

The Only Way to Know for Certain: Run the Math Against Your Lease

Intuition and comparison with neighboring tenants can flag a potential problem, but they can't confirm one. Your lease is the contract that governs what the landlord can charge. The management fee cap in your lease is the only number that matters for a management fee overcharge analysis — not what other tenants pay, not what the industry standard is, not what seems reasonable.

I built CAMAudit because running those calculations manually requires reading the lease, extracting the right provisions, and applying the correct formulas — work that most tenants don't have time for, and that professional auditors charge thousands to perform. CAMAudit does it in under 15 minutes, using your actual documents.

What Documents You Need

Your commercial lease

Key sections: CAM definitions clause, CAM exclusions clause, management fee cap, pro-rata share definition, CAM cap or base year provisions, audit rights clause

Your annual CAM reconciliation statement

Key sections: The landlord's year-end document showing actual CAM expenses, your pro-rata share applied, your estimated payments, and the true-up amount due or owed to you

If you have multiple years of reconciliations, start with the most recent one. Once you have the free scan results, you can decide whether older years warrant a full audit.
