Your CAM Charges Went Up. Can You Audit Them?

A CAM charges audit commercial lease can help a Nevada business tenant determine whether an increase in common area maintenance expenses is supported by the lease and the landlord’s records. CAM charges often cover shared property costs such as landscaping, parking lot maintenance, security, cleaning, and common-area repairs. Depending on the lease, tenants may also pay a share of insurance, property taxes, management fees, utilities, and other operating expenses. An increase is not automatically improper, but tenants should be able to check whether the charges were calculated according to the agreed terms.

In Nevada, a tenant’s right to audit these expenses generally depends on the commercial lease rather than a universal statutory right to inspect every landlord accounting record. The lease may specify which records can be reviewed, who can conduct the audit, how quickly the tenant must object, and what happens if the review identifies an overcharge. Before a deadline passes, consider consulting a Commercial Real Estate Attorney to assess the audit clause and the options available under the agreement

What Does a CAM Audit Actually Check?

A CAM audit compares the landlord’s charges with the lease’s definition of recoverable expenses and the method used to allocate those expenses among tenants. It is not simply a review of whether the total bill looks reasonable. A charge may reflect a genuine property expense but still be incorrectly billed if the lease excludes it, caps it, or requires a different allocation method.

Start with the annual reconciliation statement, the monthly estimates already paid, and the section of the lease covering CAM or operating expenses. The review should establish the total expenses included in the calculation, your share of those expenses, any applicable caps or exclusions, and whether the landlord has provided the supporting information required by the agreement.

Depending on the lease, the records needed may include general ledger details, vendor invoices, maintenance contracts, management fee calculations, occupancy assumptions, and the square-footage figures used to calculate each tenant’s proportionate share. Some leases permit an on-site inspection only; others allow a qualified accountant or lease auditor to examine and copy records. The actual wording determines the scope of access.

Why Did Your CAM Charges Increase?

Before disputing an increase, identify what changed. Some increases reflect genuine increases in insurance premiums, property taxes, utilities, labor, or maintenance costs. Others may result from changes in occupancy, management fees, the way expenses are allocated, or the landlord’s treatment of particular costs. The objective is to distinguish a legitimate increase from a calculation or lease-compliance problem.

Review the current reconciliation against the prior year. Compare each expense category rather than looking only at the final amount. If landscaping costs increased substantially, for example, check whether the supporting invoices and contracts explain the change. If the management fee rose, examine the lease’s fee formula and the base used to calculate it. If your proportionate share changed, verify the square footage and denominator used in the calculation.

The lease’s expense definition is central to this review. A lease may exclude leasing commissions, costs of attracting new tenants, certain capital improvements, costs reimbursed by insurance, or expenses attributable to a particular tenant. These exclusions are not universal; the actual lease controls. Some agreements allow certain capital costs to be passed through over time, particularly when they qualify under the negotiated language. A tenant should therefore test each disputed line item against the contract instead of assuming that a particular expense can never be charged.

Which CAM Charges Should You Examine Closely?

Several parts of a CAM reconciliation deserve careful review because they can materially affect the amount a tenant pays.

Expense exclusions and capital costs: Determine whether the lease excludes expenses such as landlord financing costs, leasing commissions, tenant improvements for other units, or costs reimbursed by third parties. If a major roof, parking lot, or HVAC project appears in CAM, check whether the lease permits that category of capital expense and whether it requires amortization or another specific treatment.

Management fees and administrative charges: Check whether the lease permits a management fee, whether the amount is capped, and how the fee is calculated. Confirm that the landlord has not applied a percentage to a cost base that the lease excludes or charged duplicative administrative fees.

Proportionate share and occupancy calculations: Review the square footage assigned to your premises and the total rentable area used in the calculation. Some leases provide for adjustments when a property is not fully occupied, sometimes called a gross-up. If your lease permits this method, check whether the landlord applied it consistently with the agreed formula and occupancy assumptions.

Taxes, insurance, and utilities: These costs can fluctuate substantially, but the supporting statements should still match the categories and allocation methods permitted by the lease. Verify that credits, refunds, or reimbursements have been accounted for where required, and check whether the landlord has charged the same cost in more than one category.

How to Request a CAM Audit Under Your Lease

The first step is to locate the audit clause. It may appear under “Common Area Maintenance,” “Operating Expenses,” “Additional Rent,” “Annual Reconciliation,” or a separate “Audit Rights” heading. Read the clause together with amendments, exhibits, and any provision governing how notices must be delivered.

Identify the deadline for requesting an audit, the period covered by the review, the records available, the qualifications required of an auditor, and any restrictions on access or confidentiality. Some leases require the tenant to give written notice within a short period after receiving the reconciliation. Others require objections to be submitted separately after the records have been inspected. Missing one deadline may limit the tenant’s ability to challenge the statement, even if the underlying calculation appears incorrect.

Next, send a written request that follows the lease’s requirements. Identify the reconciliation year, cite the applicable audit provision, specify the records requested, and retain proof of delivery. If the landlord requires an independent certified public accountant or prohibits contingency-fee auditors, comply with those terms unless they can be negotiated or legally challenged. Do not assume that the landlord must provide every document you request; the scope of the contractual audit right matters.

What If the Landlord Refuses Your Audit Request?

If the landlord refuses to provide records or limits the review, compare its response with the exact language of the lease. Determine whether the agreement requires cooperation, permits copies of records, or limits the review to an inspection at the landlord’s office. Keep the original request, delivery confirmation, response, reconciliation statement, and all follow-up correspondence together.

A refusal does not automatically establish that the landlord overcharged you, nor does it automatically entitle you to a refund. However, the lease may provide a basis to challenge noncompliance or seek an appropriate remedy. Nevada’s commercial landlord-tenant statutes do not create a blanket CAM audit right for every tenant, so the legal analysis will depend heavily on the contract and the facts.

Avoid withholding rent or deducting disputed CAM amounts from future payments without reviewing the lease and obtaining legal advice. A disagreement over operating expenses does not necessarily suspend the tenant’s payment obligations. The safer course is to preserve the dispute in writing, follow the contractual procedure, and determine how the lease requires disputed amounts to be handled while the audit proceeds..

What Happens If the Audit Finds an Overcharge?

If the review identifies an error, prepare a clear written summary showing the disputed expense, the amount charged, the relevant lease provision, the supporting records, and the corrected calculation. For example, if a management fee was calculated using expenses excluded by the lease, show how the contractual formula changes the result. Specific evidence is more useful than a general claim that the bill is too high.

The lease may specify how a confirmed overcharge is corrected, whether the landlord must issue a credit or refund, and when the landlord must reimburse audit costs. Some agreements shift audit expenses to the landlord only if the overcharge exceeds a stated threshold. Others place the cost on the tenant regardless of the outcome. Review these terms before hiring an auditor so that the likely cost of the review is proportionate to the amount in dispute.

If the parties cannot resolve the issue, the available options may include further negotiations, a contractual dispute-resolution process, or legal proceedings where supported by the agreement and applicable law. A tenant should not assume that every accounting discrepancy amounts to a legal breach; the issue is whether the charge violates the lease or another applicable obligation.

How to Protect Your Audit Rights in Future Lease Years

CAM disputes are easier to manage when the lease establishes a workable audit process from the beginning. During lease negotiations or renewal, tenants should seek a reasonable period to request an audit, sufficient time to review supporting records, and access to the invoices and calculations needed to verify charges. The agreement should also state how disputes are raised, how confirmed overpayments are corrected, and when audit costs may be shifted to the landlord.

Tenants should maintain annual reconciliation statements, monthly estimates, payment records, prior audit findings, and written objections in an organized file. When a new statement arrives, calendar both the audit-request deadline and any separate deadline for disputing the final amount. This is particularly important for businesses operating under long-term leases, where a small recurring calculation error can accumulate over several years.

Conclusion

Yes, you may be able to audit increased CAM charges, but the right and procedure usually depend on the language of your commercial lease. A careful review should test the landlord’s expense categories, exclusions, caps, allocation calculations, and supporting records against the agreed terms. Deadlines matter, and a tenant who waits too long may lose contractual rights to inspect or dispute a reconciliation.

If your CAM charges have increased unexpectedly, begin with the lease and the annual statement rather than assuming the increase is either justified or improper. A documented review can help identify errors, support a focused dispute, and clarify whether a refund, credit, or other remedy may be available
