A CAM audit is a formal review of a landlord's CAM reconciliation statement to verify that charges are accurate, properly calculated, and consistent with the lease. The audit compares the statement line items against the lease's expense definition, pro-rata share formula, gross-up provision, and any caps.

How long does a CAM audit take?

With CAMAudit, a full forensic audit runs in under 15 minutes. Traditional CPA-led audits take 4 to 8 weeks and require scheduling, document collection, and manual review. The speed advantage of CAMAudit comes from automating the extraction and detection steps.

What documents do I need for a CAM audit?

You need your commercial lease (including all addenda and exhibits) and your CAM reconciliation statement from your landlord. The reconciliation is usually sent annually, within 90 to 120 days after the close of the lease year. If you haven't received it yet, request it in writing.

What does a CAM audit actually check?

CAMAudit checks 14 categories: management fee overcharge, pro-rata share error, gross-up violation, CAM cap violation, base year error, controllable expense cap overcharge, estimated payment true-up error, gross lease charges, excluded service charges, insurance overcharge, tax overallocation, utility overcharge, common area misclassification, and landlord overhead pass-through.

Do I need an attorney to dispute CAM charges?

Not necessarily. CAMAudit generates a dispute letter draft grounded in your specific findings and lease language. Many tenants resolve CAM disputes by sending this letter directly to their landlord or property manager. For large disputes or adversarial landlords, involving an attorney is advisable.

Case Study: $23,000 Management Fee Overcharge at a Retail Strip Center

A specialty retail tenant in Texas had been paying CAM charges without incident for three years. The reconciliation statements came in, they wrote checks, and life moved on. Then they ran the numbers through CAMAudit — and Rule 3 fired immediately.

The overcharge wasn't subtle. It had been sitting in the management fee line every year, quietly compounding.

The Scenario

The tenant occupied 3,200 square feet in a Texas strip center under a triple-net lease. Annual CAM billing ran approximately $68,000. Their lease set the management fee at 3% of "gross revenues from the property" — a common structure, and one with specific language that matters.

Nothing about the deal looked unusual. The property was well-managed. The landlord communicated promptly. CAM statements arrived on time each January.

What Triggered the Audit

After three full reconciliation cycles, the tenant's finance team noticed the management fee line kept growing faster than the rest of CAM. Total square footage hadn't changed. Occupancy at the center had been stable. The growth rate didn't track with what they'd expect from a property management cost.

They uploaded their lease and the three-year CAM reconciliation statements to CAMAudit.

What CAMAudit Found

Rule 3 — the Management Fee Overcharge detection rule — flagged the issue within seconds of processing.

The lease said 3% of gross revenues. The landlord had been charging 5% — and applying that rate to a calculation base that included leasing commissions and capital improvements. Both categories are explicitly excluded under the lease's definition of "gross revenues from the property."

Two problems stacked on each other: wrong rate, wrong base.

The Math

Here's how the overcharge built up each year.

What the lease allowed:

Management fee rate: 3%
Allowable base: gross revenues, excluding leasing commissions and capital improvements
Estimated allowable base (Year 1–3 average): ~$1,540,000/yr

What the landlord charged:

Management fee rate: 5%
Base used: ~$1,540,000 gross revenues + ~$220,000 leasing commissions + ~$120,000 capital improvements = ~$1,880,000

	Allowable Fee (3% × $1,540,000)	Billed Fee (5% × $1,880,000)	Annual Overcharge
Year 1	$46,200	$94,000	~$47,800
Year 2	$46,200	$94,000	~$47,800
Year 3	$46,200	$94,000	~$47,800

Wait — those numbers reflect property-wide fees. The tenant's share of the property-wide management fee overcharge, at their pro-rata allocation, came out to approximately $7,700 per year across three years: $23,100 total.

The rate error alone (5% vs. 3%) would have been $30,800 per year property-wide. The base inflation — adding excluded items — pushed it further. Both issues showed up in the same line item on the CAM statement, which is exactly why this type of error often goes undetected without a rule specifically designed to parse management fee clauses.

"I built CAMAudit because the management fee clause is one of the most abused lines in a CAM statement. The lease says one thing, the landlord bills another, and unless you're running the math against the actual contract language, you'll never catch it." — Angel Campa, Founder of CAMAudit

The Resolution

The tenant used CAMAudit's dispute letter draft output as the foundation for their formal objection. The letter cited the specific lease section defining "gross revenues," identified the two errors — wrong rate and inflated base — and attached the three-year calculation showing the overcharge year by year.

The landlord's property manager initially pushed back, claiming the management fee structure "had always been calculated this way." The tenant's response was simple: send us the lease clause that authorizes it.

There wasn't one. The lease was clear. Within six weeks, the landlord issued a credit of $23,100 applied against the next quarter's CAM billing.

Key Takeaway

The audit rights clause in most commercial leases gives you a 3-year lookback window. That's exactly what this tenant used. Three years of unchallenged overbilling — caught and corrected because they finally read the management fee definition in their own lease.

Watch for two specific problems in your management fee line:

Rate creep. The lease specifies a percentage. Verify it matches what's on the CAM statement. A 2% gap at scale is not a rounding error.
Base inflation. Even if the rate is right, a landlord who adds excluded items to the calculation base is overbilling. Capital improvements and leasing commissions are almost universally excluded — but only matter if you check.

If your lease is a triple-net lease and you've never audited the management fee calculation against your actual contract language, you may be paying more than you owe.

Frequently Asked Questions

Can a landlord charge a different management fee rate than what the lease specifies?

No. The management fee percentage in your lease is a binding contractual term. If your lease says 3% and the landlord bills 5%, that's an overcharge regardless of industry norms or what the landlord says is "standard." Always verify the rate on your CAM statement against the exact language in your lease's CAM definitions section.

What counts as an excluded item in a management fee base calculation?

Most commercial leases explicitly exclude capital improvements, leasing commissions, and tenant improvement allowances from the gross revenue base used to calculate management fees. Some leases also exclude debt service, depreciation, and financing costs. The specific list depends on your lease language — CAMAudit's Rule 3 parses your actual contract to identify what's excluded.

How far back can I audit a management fee overcharge?

The audit window is typically defined by your lease's audit rights clause. Most commercial leases allow a 3-year lookback from the date you request an audit. Some states cap the lookback under their statute of limitations for contract claims, which may be shorter or longer. Texas, where this case occurred, follows the lease's audit rights clause for CAM disputes in most commercial contexts. CAMAudit flags the audit window based on your lease terms.
