What to do when a tenant disputes a CAM reconciliation

1. Identify what is actually being disputed

A CAM dispute is rarely one thing. A tenant may be challenging the dollar amount, the allocation method used to calculate their share, whether a specific expense should be recoverable at all, or simply the timing or form of the notice. Treating all of these as the same conversation makes the response longer and less convincing than it needs to be.

• The total dollar amount billed or reconciled
• The allocation method or the tenant’s calculated share
• Whether a specific expense category is recoverable under the lease
• The notice itself—timing, form, or required detail

2. Check the lease’s own dispute and audit-rights language before responding

Many commercial leases give tenants an explicit right to review or audit CAM records within a defined window after receiving a reconciliation, sometimes at the tenant’s expense, sometimes with cost-shifting if a material overcharge is found. Some leases also specify how a dispute must be raised and what happens to payment obligations while it is pending.

Read this language before crafting a response. A reply that ignores a contractual audit right, or asks a tenant to simply take the numbers on faith, invites exactly the escalation the process was meant to avoid.

3. Pull the record before you reply

A credible response starts with the same documents the reconciliation itself was built on: the source invoices and statements behind the disputed category, the tenant’s square footage and pro-rata share, and—when the dispute is about a change—the prior year’s comparable figures.

Assembling this after a dispute is raised is slower and more stressful than keeping it organized from the start, which is the practical argument for reconciling from a connected record rather than a rebuilt annual spreadsheet.

4. Respond with the specific basis, not a general summary

Address the exact question raised. If the dispute is about an amount, show the category-level breakdown and the tenant’s calculated share, not just the total. If it is about recoverability, cite the lease provision and explain how the expense fits it. If it is about allocation, show the square footage and pool used and why.

A response that answers a narrower question than the one asked reads as evasive even when the underlying number is correct.

5. Know when to bring in an accountant or attorney

Most disputes resolve with documentation. Escalate to a professional when a tenant formally exercises a contractual audit right, when the disputed amount is material relative to the property’s CAM pool, when the same category is disputed by more than one tenant (which can indicate a real allocation or categorization error rather than a single tenant’s misunderstanding), or when the disagreement is really about how to interpret ambiguous lease language rather than the underlying math.

6. Preserve the resolution, whatever it is

Keep the original reconciliation, the dispute correspondence, the supporting documents provided, and the final resolution—whether that is an adjustment, a credit, a waiver, or a confirmation of the original figure—in the tenant’s record. That history protects both sides in a future dispute and is often requested during a sale, refinance, or lease renewal.

This process is not legal or accounting advice. A lease provision you cannot resolve confidently, or a dispute involving a material dollar amount, should be reviewed by qualified counsel or an accountant before you respond.
