What Is a CAM Audit? The Complete Guide for Commercial Tenants

A CAM audit is a forensic review of your landlord's annual CAM reconciliation statement. The goal: find charges that exceed your lease limits, expenses your lease excludes, or miscalculations in how costs are split across tenants. According to IREM's Journal of Property Management, 30% of CAM statements contain errors.

When Do You Need a CAM Audit?

A few situations where running an audit is worth it:

• Within 30–90 days of receiving your CAM reconciliation (most leases have a dispute window)
• When your CAM charges went up significantly year over year without a clear reason
• When you're negotiating a lease renewal and want to know your actual exposure
• When a new landlord took over the property and the billing changed
• Any time your annual CAM bill is over $5,000 — the math makes an audit worth it at that level

Break-even: $199 ÷ 4% average error rate = $4,975 annual CAM — any CAM bill over $5,000/year makes CamAudit worth running.
