Audit Rights in Commercial Leases: Why Tenants Must Protect Themselves

Commercial lease agreements involve more than just rent payments. Tenants are often responsible for additional expenses, including property taxes, maintenance fees, insurance, and other operating costs. These charges—commonly referred to as Common Area Maintenance (CAM) expenses or operating expense pass-throughs—are typically managed and calculated by the landlord.
But how can tenants be sure they are being billed fairly?
Tenants who negotiate the right to audit their landlord’s financial records gain a critical tool to ensure transparency, verify charges, and challenge any discrepancies. Without this protection, businesses may unknowingly overpay for expenses that should not have been passed down to them.
If you’re leasing commercial space, understanding audit rights and how to enforce them can prevent costly overcharges and keep landlords accountable.
What Are Audit Rights in a Commercial Lease?
Audit rights give tenants the ability to review their landlord’s financial records related to operating expenses, CAM fees, and other shared costs. These rights allow a tenant (or their accountant or third-party auditor) to examine invoices, contracts, tax records, and other documents to verify whether the amounts charged are accurate and in line with the lease agreement.
Landlords typically estimate expenses at the beginning of the lease year and then reconcile them annually. If expenses exceed projections, tenants may be required to pay the difference. Without audit rights, tenants have little recourse if they suspect errors or inflated charges.
A well-structured lease will clearly define how and when a tenant can request an audit, the scope of documents they can review, and the process for resolving disputes.
Why Audit Rights Are Critical for Tenants
Preventing Overcharges and Hidden Fees
Landlords make mistakes, and some may intentionally pad operating expenses to increase revenue. Common issues found in lease audits include:
Double billing of certain expenses
Incorrect pro-rata share calculations
Pass-through of non-allowable expenses (e.g., capital improvements, legal fees unrelated to property management)
Administrative fees that exceed lease terms
Without audit rights, tenants have no way to verify whether they are being charged correctly.
Holding Landlords Accountable
Some landlords count on tenants not reviewing their invoices in detail. Audit rights introduce accountability, ensuring that landlords maintain accurate records and only pass through legitimate costs. When tenants exercise their right to audit, landlords are less likely to include questionable charges in the first place.
Recovering Money from Past Overcharges
Many commercial leases allow tenants to recover overcharges from previous years if discrepancies are found in an audit. The lease should specify the lookback period—typically one to three years. This means a thorough audit could result in substantial refunds or credits applied to future payments.
Strengthening Lease Negotiation Power
Tenants with audit rights are in a stronger position when negotiating lease renewals or future agreements. If past audits have uncovered errors, tenants can demand more favorable terms or greater transparency before signing a new lease.
Key Elements of a Strong Audit Rights Clause
For audit rights to be effective, they must be clearly defined in the lease. Tenants should negotiate terms that provide meaningful access to financial records and prevent landlords from creating obstacles.
Clear Audit Timeframes
The lease should specify:
How often audits can be conducted (e.g., annually after expense reconciliation)
The deadline for requesting an audit after receiving the reconciliation statement
The period covered by the audit (e.g., the last two or three years)
Scope of Documents
Audit rights should include access to:
Vendor contracts and invoices
Tax assessments and insurance statements
Utility bills and maintenance records
Internal accounting reports detailing cost allocations
The more restrictive the lease is on document access, the harder it becomes to identify errors.
Who Can Conduct the Audit?
Tenants should have the right to:
Conduct the audit internally
Hire an independent auditor or accountant
Use a third-party audit firm that specializes in lease expense reviews
Some landlords may try to limit audits to internal tenant employees, making it harder to perform a thorough review.
Cost of the Audit
Landlords often insist that tenants cover the cost of the audit. However, leases should include a provision stating that if an overcharge above a certain percentage is found (e.g., 3%–5%), the landlord must reimburse the tenant for audit costs. This discourages landlords from passing through excessive charges.
Dispute Resolution and Arbitration
If an audit reveals discrepancies and the landlord disputes the findings, the lease should outline a clear resolution process. Arbitration is often the preferred method to resolve disputes efficiently without resorting to lengthy litigation.
A well-drafted arbitration clause should specify:
Who selects the arbitrator (often a neutral third party)
The timeline for arbitration proceedings
Whether the arbitrator’s decision is binding
Without a clear dispute resolution process, landlords can delay or ignore valid audit findings.
How to Exercise Audit Rights
Step 1: Review the Annual Reconciliation Statement
At the end of each lease year, landlords provide an operating expense reconciliation statement. Tenants should carefully review this document to identify significant increases or unexpected charges.
Step 2: Compare Charges to Lease Terms
Confirm that expenses align with the lease agreement. Look for non-permitted charges, errors in pro-rata share calculations, and administrative fees that exceed agreed-upon limits.
Step 3: Notify the Landlord in Writing
If discrepancies are found, tenants must notify the landlord within the timeframe specified in the lease (usually 30 to 90 days). The notice should request supporting documentation and state the intent to conduct an audit.
Step 4: Conduct the Audit
An internal team or third-party auditor reviews the landlord’s records to verify expenses. If overcharges are found, the tenant presents the findings and requests a refund or adjustment.
Step 5: Resolve Disputes (If Necessary)
If the landlord disputes the audit findings, the resolution process outlined in the lease—whether direct negotiation, arbitration, or legal action—will determine the next steps.
Protect Your Business with Strong Audit Rights
Without audit rights, tenants are at the mercy of landlords when it comes to operating expenses. Overcharges, hidden fees, and unclear expense allocations can add up to thousands—or even millions—of dollars over the course of a lease.
Negotiating strong audit rights upfront ensures transparency and provides a mechanism to challenge questionable charges. Tenants should work with experienced real estate brokers and attorneys to draft lease terms that give them full access to financial records, fair dispute resolution procedures, and the ability to recover overpayments.
For businesses looking to protect their bottom line, the right to audit is not just a privilege—it’s a necessity.
Understanding and exercising your audit rights in commercial leases is essential to ensuring accurate expense allocations and protecting your financial interests.
