Commercial lease audits can uncover overbilling when CAM reconciliations, exclusions, caps, or gross-up provisions are misapplied. For tenants paying $100,000+ annually in CAM, even a small billing error can be financially meaningful. The recovery amount depends on lease complexity, landlord billing practices, and how long the audit period covers.
Most leases provide an audit right of 12-24 months from the date the CAM reconciliation statement is delivered. Some leases have a longer 36-month window covering multiple years. The audit must typically be completed within 60-90 days after notice is given. Missing the audit window permanently waives the right to dispute those charges.
Landlords can charge audit costs to the tenant if the audit reveals no overbilling, or if the lease specifically permits cost recovery. If the audit reveals an overbilling above a specified threshold (often 3-5%), the lease typically requires the landlord to pay audit costs. Negotiating favorable audit cost provisions is important at lease inception.
