CAM charges are supposed to cover the actual cost of operating and maintaining common areas shared by all tenants, but what qualifies varies by lease. The question of what's legitimately included versus what's a billing error is answered by your specific lease definition, not by general standards. CAMAudit uses your lease to determine what belongs in your CAM pool.
TL;DR
Understanding what should and should not be in your CAM pool is the foundation of any meaningful dispute; knowing the rules means you can spot violations without needing a professional to tell you first.
Who this is for
Tenants who are new to NNN leases or who received a reconciliation and want to understand which line items are legitimate before they go further.
Who this is not for
Tenants looking for a general definition of CAM charges without reference to their specific lease; the general definition is a starting point, but only your lease controls.
Gross Lease Charges
Identifies charges that only belong in gross lease structures.
Excluded Service Charges
Flags any line item your lease explicitly excludes from the CAM pool.
Common Area Misclassification
Catches capital improvements, structural costs, and landlord-benefit expenses misclassified as operating CAM.
