A CAM audit verifies what you were billed. A CAM dispute recovers the overcharge. Understanding the sequence and which comes first prevents costly mistakes.
TL;DR: A CAM audit verifies whether charges are accurate. A CAM dispute asserts a specific overcharge claim to recover money. The audit comes first, it produces the dollar figure you need. Without an audit, a dispute is a complaint with no number attached. Most disputes resolve within 90 days once the tenant has a precise calculation.
Run the audit before you decide whether this applies to your lease.

Find My OverchargesSee a sample report first“I built CAMAudit because tenants kept sending dispute letters without numbers. A letter that says 'I believe I was overcharged' goes to a ticketing queue. A letter that says 'the management fee of $27,200 exceeds the 5% cap in Section 6.4(a) by $10,200' forces a specific response.”
These two terms get used interchangeably in commercial real estate circles, which causes confusion about the right process and the right sequence. They are related, one typically precedes and enables the other, but they are distinct activities with different purposes, different tools, and different outcomes.
A CAM audit is the process of verifying that the amounts billed in a CAM reconciliation statement match what the lease actually permits. It is an accounting and legal review: you take the landlord's numbers, check them against your lease definitions, and calculate whether what was billed is accurate.
An audit can be informal (a tenant does their own review with a spreadsheet) or formal (a professional lease auditor or CPA examines the landlord's underlying records). The output of an audit is a finding: the charges were accurate, or there is an overcharge of $X.
A CAM dispute is the process of asserting an overcharge claim against the landlord and seeking repayment. It is a negotiation or legal process: you present your calculation to the landlord, ask them to correct it, and pursue the claim through whatever escalation path the lease or law provides if they don't.
A dispute requires a prior audit, at minimum, a calculation. Without a documented overcharge figure, there is nothing to dispute. The audit is the foundation; the dispute is what you build on top of it.
| CAM Audit | CAM Dispute | |
|---|---|---|
| Purpose | Verify accuracy of CAM charges | Assert and recover an overcharge |
| Output | Finding (correct, or overcharge of $X) | Settlement, credit, or legal judgment |
| Process | Accounting / lease review | Negotiation, mediation, or litigation |
| Who does it | Tenant, CPA, or audit firm | Tenant, attorney, or mediator/arbitrator |
| When | Within dispute/audit window after reconciliation | After audit identifies overcharge |
| Governed by | Lease audit rights clause | Lease dispute resolution clause + applicable law |
| Required to dispute | Yes (provides the claim amount) | No (audit is the prerequisite) |
The most common mistake in CAM disputes is sending a dispute letter draft before completing the audit. A dispute letter draft that says "we believe we have been overcharged" without a specific dollar amount is easy to reject with a general denial. A dispute letter draft that says "the management fee of $27,200 exceeds the 5% cap in Section 6.4(a) by $10,200" forces a specific response.
The audit establishes the overcharge. The dispute asserts the overcharge. You cannot effectively do the second without the first.
There is also a time dimension. The dispute window (the period within which you must formally dispute a reconciliation statement) and the audit window (the period within which you must request audit access) may be different in your lease. Some leases require formal dispute within 90 days of receiving the reconciliation but permit audit requests for up to two years. Others have the same window for both.
In practice: run the audit first, within whatever window your lease provides, and file the dispute letter draft based on those findings. If the audit finds nothing, there is nothing to dispute. If it finds overcharges, the dispute letter draft is built on solid ground.
You can send a dispute letter draft without a formal professional audit. Many tenants do an informal audit themselves, reviewing the reconciliation statement against their lease and computing the overcharge, and then send a dispute letter draft based on that review. This is the most common approach for straightforward overcharges like a management fee over the lease cap, where the calculation requires only the statement and the lease.
What you cannot do is dispute without any calculation. A dispute letter draft must state a specific dollar amount supported by a specific calculation. The level of rigor of that calculation (informal tenant review versus professional audit firm) affects the letter's weight, not its validity.
For larger or more complex claims, where the overcharge may depend on reviewing the landlord's underlying invoices or general ledger, you may need to submit an audit rights request before you can complete the calculation for your dispute letter draft. In that case, the sequence is: preliminary review → dispute window preserved → audit request → full calculation → dispute letter draft with complete numbers.
Yes, and it can be a valuable exercise even when no dispute follows.
Periodic CAM audits, even when no specific overcharge is suspected, often reveal methodology issues: a management fee creeping toward the cap, a denominator that has changed without notice, CapEx items being amortized into operating expenses in ways that may not be supported by the lease. Catching these issues before they accumulate creates negotiating leverage at lease renewal and reduces future exposure.
An audit that finds no overcharge is also informative: it confirms the landlord is billing correctly, reduces uncertainty about future reconciliation statements, and may give you confidence to sign a renewal without extensive CAM negotiation.
Some larger commercial tenants with multiple leases audit every reconciliation statement as a matter of policy. The cost of routine audits is small relative to the savings when overcharges are identified early.
Within the umbrella of "CAM audit," two types have meaningfully different scope:
Preliminary review (informal): The tenant reviews the reconciliation statement against their lease and identifies probable overcharges based on the data in the statement itself. This is sufficient for straightforward overcharges (management fee cap, obvious CapEx classification, pro-rata share using a clearly wrong denominator). It does not require audit rights invocation or landlord cooperation.
Full records audit (formal): The tenant invokes their lease audit rights and inspects the landlord's underlying accounting records: general ledger, vendor invoices, management fee calculations, pro-rata share data, insurance certificates. This is necessary when: (a) the reconciliation statement lacks sufficient detail to identify the source of apparent overcharges, (b) the preliminary review suggests overcharges but the calculation requires records the landlord has not provided, or (c) the amount at stake justifies the additional cost and time.
Most leases condition the formal records audit on a written request within a specified window. Failing to invoke this right formally, in writing, citing the correct lease provision, can result in losing the right to audit those records.
