In the 2026 commercial real estate market, Common Area Maintenance (CAM) fees have become a significant “hidden” cost for business owners. As property taxes and insurance premiums surge across the U.S., many landlords are passing these increased operational costs directly to tenants through CAM reconciliations.

Without a proper audit, you could be unknowingly subsidizing your landlord’s capital improvements or administrative errors. At Lforlaw, we believe every commercial tenant should have the tools to verify that every dollar charged is a dollar earned by the property.

Understanding CAM: What You Should Be Paying

Common Area Maintenance fees are intended to cover the shared costs of operating a commercial property—think snow removal, parking lot lighting, landscaping, and lobby maintenance. However, the “devil is in the details” of your lease.

Most commercial leases fall into two categories for CAM:

1. Triple Net (NNN): You pay your pro-rata share of all taxes, insurance, and maintenance.

2. Gross Lease with a Base Year: You pay the increase in operating expenses over the costs incurred during your first year of the lease (the “Base Year”).

The 2026 Commercial CAM Audit Checklist

If your annual reconciliation statement just arrived and the numbers seem high, use this checklist to spot common “overcharges.”

1. Capital Improvements vs. Repairs

Standard CAM should only cover repairs (fixing a leak). It should not cover capital improvements (replacing the entire roof or installing a new HVAC system).

• The Audit Check: Look for large, one-time charges. Landlords often try to “expense” a capital project in a single year instead of amortizing it over its useful life.

2. The “Pro-Rata” Math Check

Your share of expenses is based on your square footage divided by the total “Leasable Area” of the building.

• The Audit Check: Ensure the landlord is using the Total Leasable Area, not just the “Occupied Area.” If the building is 50% vacant, you should not be paying a higher percentage of the lobby’s electricity bill just because you’re the only one there.

3. Management & Administrative Fees

Most leases cap management fees at a percentage of the total rent (usually 3–5%).

• The Audit Check: Check for “double-dipping.” Is the landlord charging a 5% management fee plus a separate administrative fee for the same staff?

4. Pyramiding Insurance & Taxes

• The Audit Check: Verify that the property tax bill matches the local assessor’s data and ensure you aren’t being charged for “umbrella” insurance policies that cover properties other than the one you occupy.

How to Dispute an Overcharge

In 2026, many states have strictly enforced “Audit Windows.” You typically only have 30 to 90 days after receiving your annual reconciliation to dispute the charges.

1. Submit a Written Information Request: Request the “General Ledger” for the property for the previous year.

2. Check for “Expense Caps”: Review your lease for “Year-over-Year Caps” (e.g., a rule stating CAM cannot increase more than 5% annually).

3. Hire a Professional: If the discrepancy is large, a forensic CAM auditor or a specialized attorney can often find enough errors to pay for their own fee.

Conclusion

A commercial lease is a partnership, but that partnership requires transparency. In an era of fluctuating utility costs and rising taxes, a CAM audit is not an act of aggression—it is a standard business practice to ensure your lease remains sustainable. If your reconciliation statement looks inflated, the burden is on you to speak up before your audit window closes.

Are you concerned that your landlord is miscalculating your pro-rata share or hiding capital expenses in your CAM fees? Don’t settle for “estimated” costs. Contact Lforlaw today to connect with a commercial lease attorney who can review your audit rights and help you recover overpaid expenses.
