Your lease does not include the right to audit the landlord's operating expense records. Without audit rights, you have no way to verify that CAM charges, tax pass-throughs, and other operating expenses are accurate and fairly allocated.

Flagged when audit rights are set to false or when no audit rights provision is found in the lease.
CAM reconciliation errors are lease-specific: excluded expenses, capital items, incorrect allocation percentages, and management-fee calculations all depend on the exact lease language. For a tenant paying $25,000 annually in CAM charges, even a 10% unsupported charge equals $2,500 per year or $25,000 over a 10-year term. Without audit rights, tenants have no contractual mechanism to identify or recover these overcharges.
Insist on explicit audit rights in your lease with at least 180 days to dispute CAM reconciliation statements. Require the landlord to provide itemized operating expense records upon request, including invoices and contracts for major expense categories. Negotiate that if the audit reveals overcharges exceeding 5% of total CAM, the landlord pays the cost of the audit. Include a provision for retroactive recovery of overcharges for the full lease term, not just the current year. Even without formal audit rights, you can run a preliminary check on your reconciliation at <a href="https://www.camaudit.io" target="_blank" rel="noopener noreferrer">CamAudit.io</a> - it applies 14 detection rules and surfaces the specific overcharge categories most likely to be present.
It is difficult to add audit rights after lease execution. Your best opportunity is during lease renewal negotiations or when the landlord requests a lease amendment for other purposes. Some tenants successfully negotiate audit rights by offering a longer renewal term in exchange.
CAM audits across institutional properties frequently surface billing errors in the landlord-prepared reconciliation. CAM audit guidance from Mohr Partners describes invoice, contract, and allocation review as the practical way to identify charges that do not match the lease. Common issues include double-counting expenses, including capital expenditures that should be excluded, and miscalculating pro-rata shares.
CAM audits are typically performed by specialized commercial real estate auditing firms. These firms work on a contingency basis (taking a percentage of recovered overcharges) or for a flat fee. Expect to pay $3,000 to $10,000 for a comprehensive audit.
