Free Tenant Audit Risk Scorecard

The top risk factors are large tenants with high CAM bills (they gain the most from an audit), leases with short audit windows, year-over-year billing increases above 5 to 10%, complex pro-rata calculations, and tenants with experienced real estate counsel. National tenants with lease admin teams audit more often than local tenants.

Keep a clean reconciliation process. Document every expense allocation, make sure gross-up calculations match lease language, check pro-rata shares against current measurements, and keep a clear audit trail from GL entry to tenant invoice. Reviewing your top 10 tenants each year catches most issues before outside auditors do.

The five most common findings are: (1) non-recoverable expenses in the CAM pool, (2) gross-up applied wrong or skipped, (3) pro-rata shares based on old square footage, (4) capital costs not properly amortized, and (5) management fees above lease caps. These five areas make up the bulk of tenant audit corrections.

Leases with broad audit rights (covering multiple years at once), short notice windows, tenant-favorable definitions of operating expenses, and provisions that give audit costs to the tenant when errors top a threshold (typically 3 to 5%) carry the most exposure. Full NNN leases with detailed exclusion lists also cause more disputes than simple gross-up structures.

Industry data suggests 10 to 15% of commercial tenants with audit clauses use them in any year, and the rate rises when the economy slows. Large national tenants with dedicated lease admin teams audit on a fixed cycle regardless of market conditions. The average audit results in a credit of 2 to 5% of billed operating expenses.
