What Exactly is a CAM Audit?

A CAM audit services is a comprehensive review of a commercial lease’s CAM charges, reconciling actual expenses with what the lease allows. The audit examines whether maintenance costs, property insurance, taxes, utilities, and other pass-through expenses have been correctly calculated and fairly allocated among tenants. 

During such an audit, professionals review lease provisions, general ledger entries, invoices, expense categories, and cost-allocation methodologies. They check whether items billed to tenants are truly part of common-area maintenance — and whether exclusions or non-recoverable expenses have been mistakenly passed on. 

For tenants, this can expose overcharges or improper billing. For landlords, it ensures compliance and helps prevent disputes.
