Your lease's audit rights clause entitles you to CAM expense records. Here is what to request, and what to do if your landlord refuses or stalls.
Most commercial leases include an audit rights clause giving tenants the right to inspect CAM expense records. Landlords must provide invoices, receipts, management contracts, and expense ledgers within the time specified in your lease, typically 30 to 60 days after your written request.

Audit Rights Clause
A commercial lease provision giving tenants the contractual right to inspect the landlord's books and records supporting the annual CAM reconciliation, typically within a 1 to 3 year lookback period and subject to 30 to 60 days' written notice.
TL;DR: Your lease's audit rights clause entitles you to 12 categories of CAM documentation, including vendor invoices, the property management agreement, the rent roll, and gross-up worksheets. Most leases require delivery within 30 to 60 days. Landlord refusal is a breach of the lease and creates a favorable evidentiary position in any subsequent dispute.
Most tenants never exercise this right. They receive the annual reconciliation, pay the balance, and move on. The tenants who conduct audits, by contrast, recover an average of $5,000 to $8,000 per property per year according to industry data, often for errors that recurred across multiple reconciliation years. The audit rights clause is the legal foundation that makes this recovery possible.
This guide explains what the audit rights clause contains, what documentation you are entitled to request, how to make the request effectively, and what to do if your landlord refuses or stalls.
The audit rights clause (sometimes called the "examination rights" or "inspection rights" clause) is a provision in most commercial leases that gives tenants the contractual right to inspect the landlord's books and records supporting the annual CAM reconciliation. It typically appears in the Operating Expenses or Additional Rent section of the lease, or in a dedicated section titled "Audit Rights" or "Tenant's Right to Examine Records."
A typical tenant-favorable audit rights provision reads:
"Tenant shall have the right, upon not less than [30] days' prior written notice to Landlord, to audit or examine Landlord's books and records supporting the annual reconciliation statement for any lease year within the prior [3] years. Landlord shall make available at the property management office, or at Tenant's request, deliver to Tenant copies of all supporting invoices, receipts, contracts, and other documents reasonably necessary for Tenant to verify the accuracy of the reconciliation."
A landlord-favorable version might limit the lookback to one year, require 60 days' advance notice, restrict the audit to Tenant's own employees (excluding outside CPAs or consultants), and condition the right on the tenant being current on all payments.
The differences in these provisions produce dramatically different practical outcomes. A one-year lookback means a systematic overcharge that has run for three years only produces one year of recovery. A requirement that the audit be performed by Tenant's employees effectively eliminates the right for most small and mid-size tenants.
The following 12 categories of documentation represent the complete record needed to audit a CAM reconciliation. Request all of them in a single written request. Narrowing the request to only the items you think are relevant risks missing records that would reveal additional overcharges.
1. Annual CAM reconciliation statement with all line items The summary reconciliation you already received is not sufficient. You need the full line-by-line breakdown showing each expense category, the vendor or cost center, the amount, and the allocation methodology.
2. Monthly management reports for the audited year Monthly variance reports show actual versus budget by category and can reveal mid-year corrections, reclassifications, or expense shifts that do not appear in the annual summary.
3. Vendor invoices and contracts for major expense categories Request invoices for all vendors representing more than $5,000 in annual charges (or whatever threshold your lease specifies). This includes cleaning contracts, landscaping, security, maintenance services, and utilities.
4. Property management agreement The management contract between the landlord and property management company shows the actual fee percentage agreed upon, which may be lower than the fee charged to tenants in the reconciliation.
5. Insurance policy declarations and premium statements Policy declarations show which properties are covered under each policy, the coverage amounts, and the total premiums. Allocation to a single property should reflect only the premium attributable to that property's coverage.
6. Property tax assessment and payment records Request the tax bill from the applicable county or municipal authority, assessment notices, any valuation disputes filed, and documentation of the amounts actually paid versus the amounts billed to tenants.
7. Utility billing records and calculations This includes invoices from utility providers, sub-meter readings if applicable, and the calculation showing how total utility costs were allocated to tenants. Common errors include charging the entire building's utility usage to the CAM pool without sub-metering tenant spaces.
8. Capital improvement schedule and invoices A list of capital projects during the year, with classification as either expense or capital, and invoices for any project over $10,000. Capital improvements should not be included in CAM in the year incurred (they should be either excluded entirely or amortized over useful life).
9. The rent roll (all tenant areas and GLA/GLOA denominator) The rent roll lists all tenants, their square footages, and their lease terms. It is the documentation needed to verify the denominator used in your pro-rata share calculation. Request the rent roll as of January 1 and December 31 of the audited year.
10. Any adjustments, credits, or reclassifications made during the year Year-end journals and adjusting entries can shift expenses between categories or reverse charges without disclosure. Request the general ledger trial balance and any year-end adjusting entries for the property's operating expense accounts.
11. Gross-up calculation worksheet If the reconciliation includes a gross-up adjustment for below-stabilized occupancy, request the worksheet showing which expenses were adjusted, the actual occupancy percentage, the target occupancy percentage, and the methodology applied.
12. CAM cap calculation with base year documentation If your lease includes a CAM cap, request the worksheet showing how the cap ceiling was calculated, including the base year expenses, the cap percentage, and the cumulative or non-cumulative calculation.

Refusal or non-response to an audit rights request is itself a breach of the lease in most jurisdictions. Document every refusal carefully.
If the landlord denies the request: Respond in writing noting that the request was made under the lease's audit rights clause (cite the section) and that denial of the request is a breach of your contractual rights. Request a written explanation of the basis for denial.
If the landlord imposes conditions not in the lease: Some landlords respond by conditioning document production on the tenant being current on all payments, signing a confidentiality agreement, or limiting the audit to a shorter period than the lease allows. Unless your lease expressly imposes these conditions, you are not required to accept them. Respond in writing noting the condition is not in the lease and reiterating your request without conditions.
What refusal means for your dispute position: A landlord who refuses to produce supporting documentation for a reconciliation they are asking you to pay has weakened their own position. In any subsequent arbitration or litigation, the refusal to produce records is relevant evidence. Courts and arbitrators in commercial lease cases have awarded adverse inferences against landlords who refused to produce CAM records after a properly made audit request. Document all refusals with dated copies of your requests and their responses (or non-responses).
Escalation for documented refusal: If the landlord refuses to produce records within the time specified in your lease after a properly made written request, consult a commercial real estate attorney about your remedies, which may include: injunctive relief ordering production of the records, a declaratory judgment that the reconciliation is unenforceable pending production, or a claim for breach of the audit rights clause.
Incomplete production is more common than outright refusal. You request 12 categories and receive 4. Here is how to handle it.
Document what was and was not provided. Respond in writing within a few days of receiving partial production, itemizing specifically which requested items were not provided and requesting them again with a new deadline.
Use the incompleteness in your dispute. If you identify an overcharge based on what was provided and the landlord later argues that additional records would explain the charge, the fact that they failed to produce those records when requested is a significant point in your favor. Document when you made the request and what was not produced.
Do not assume the missing records would explain the charge. Tenants sometimes receive partial production and wait indefinitely for the rest, delaying their dispute. If you have enough information to identify an overcharge based on what you have, send the dispute letter draft. Note in the letter draft that additional documentation was requested and not yet produced, and that additional overcharges may be identified upon receipt of complete records.
California SB 1103 (effective January 1, 2025): Created statutory documentation rights for qualifying small commercial tenants, defined as tenants with no more than 5 employees leasing space of 1,750 square feet or less. Qualifying landlords (owning more than a certain number of units) must provide lease translations in the tenant's language and specified documentation of charges. Tenants who qualify under SB 1103 have statutory documentation rights in addition to any lease-based audit rights.
Texas: No general statutory audit right exists for commercial tenants. All documentation rights depend entirely on lease terms. The four-year statute of limitations for written contract claims (Tex. Civ. Prac. & Rem. Code § 16.004) applies to overcharge claims and determines the maximum lookback period.
New York: A six-year statute of limitations under CPLR § 213 applies to written contract claims, though lease provisions can contractually shorten this period. No specific statutory audit right exists beyond lease terms.
Illinois: A ten-year statute of limitations for written contract claims (735 ILCS 5/13-206) creates the longest recoverable lookback period of any major commercial real estate state.
Florida: A five-year statute of limitations (Fla. Stat. § 95.11). Commercial leases in Florida frequently include a one-year audit rights window, which contractually limits the recoverable period.
In all states, the shorter of the lease audit window and the statutory limitations period controls. A lease with a 90-day audit window effectively limits recovery to the current year even where state law allows a longer lookback, because the lease's window controls when the dispute right arises.
“I built CAMAudit because tenants were paying CAM bills they had a contractual right to verify and never knew it. The audit rights clause in your lease is your legal foundation. But the clause only works if you exercise it, and most tenants never send the documentation request. The landlord's records are where overcharges become provable.”
