Yes – you can challenge CAM charge increases, and the lease usually sets the rules for doing it. A sudden jump in common area maintenance (CAM) charges can quickly disrupt a commercial budget. The total you owe depends on how the landlord tracks and explains costs, and the lease terms often control whether an increase holds up.
Start with what the lease allows
Many disputes turn on whether the landlord followed the CAM clause you agreed to. The lease may define “operating expenses,” cap management fees, exclude capital items or require a set method to split costs in multi-tenant sites.
The lease may also set a review process, such as notice deadlines, backup records or an audit right. Track those steps early. Many CAM audit rights expire within a set window, and missing the deadline can result in waiver under the lease.
Check for charges that may not belong
Once you know the rules, compare the invoice to the lease line by line. You can often challenge items that appear to be the landlord’s own operating costs, charges shifted from other areas of the property, or work that does not serve shared spaces. Charges commonly worth reviewing include:
- Costs outside the lease definition of common area expenses
- Capital improvements billed without the required amortization method
- Work serving vacant units or a landlord’s private benefit
- Unsupported “administrative” fees that exceed stated caps
These issues matter most when the invoice lacks detail or the increase is steep. Put objections in writing, cite the lease and ask for support so the dispute stays focused.
How to request records and frame your objection
After you spot red flags, ask for records and a clear cost breakdown. While state law may fill gaps where the lease is silent, commercial tenants generally have fewer statutory protections than residential tenants.
You also need to weigh deal impact, including renewal options, default exposure and available remedies. A review based on lease terms can help you decide whether to negotiate directly, exercise an audit right, or pursue a formal legal claim if the parties cannot resolve the dispute.
When the dispute is worth pursuing further
CAM disputes come down to the lease and the landlord’s records. Acting early – putting objections in writing and tracking audit deadlines – keeps your options open. If the disputed amount is significant, an attorney can help you decide whether to negotiate, audit the charges, or file a claim.
