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.

How to Identify Capital Expenditures Hidden in Your CAM Statement

Capital expenditures — roof replacements, HVAC system overhauls, elevator modernizations, major parking lot repaving — are almost universally excluded from CAM charges under commercial leases. These are property improvements that extend the building's useful life, and their cost belongs to the landlord, not the tenants. Yet they frequently appear in CAM reconciliation statements, sometimes accurately labeled as improvements, more often buried inside vague line items like "building maintenance," "major repairs," or "building systems."

Finding a CapEx pass-through isn't always obvious. You need to know what to look for, where to look, and how to apply the distinction between an ordinary repair (which typically is a CAM expense) and a capital replacement (which typically is not). That distinction has a well-established IRS standard behind it, and it's the same standard courts apply when tenants dispute these charges.

40% of CAM reconciliations contain material errors (Tango Analytics/PredictAP, 2023) CapEx buried in CAM is one of the most financially significant error types — a single misclassified roof replacement can add thousands of dollars to a tenant's annual bill for the amortization period.

8 Steps to Identify CapEx in Your CAM Statement

1. Pull your lease's CapEx exclusion language

Open your lease's CAM exhibit and find the definition of excluded expenses. Most leases include language like:

"Operating Expenses shall not include: capital expenditures, as determined in accordance with generally accepted accounting principles..."

Or more specifically:

"...costs of capital improvements, capital replacements, or capital repairs, as defined under GAAP, shall be excluded from CAM..."

Note the exact standard your lease uses. "GAAP" is common. Some leases reference IRS capitalization rules. Some set their own threshold: "any single expenditure exceeding $[X]." That threshold is your primary filter.

2. Identify your lease's CapEx threshold

Many leases define capital expenditure by dollar amount: any single-item expenditure over $5,000 or $10,000 is capital and excluded from CAM. Find that number in your lease. It's often in the CAM exhibit definitions or in a section titled "Excluded Expenses."

If your lease doesn't set a threshold, GAAP and IRS guidance apply. Under IRS regulations, a cost is generally capital if it:

Betters the property (more than restores it to normal condition)
Restores the property (brings it back to operating condition after deterioration)
Adapts the property to a new or different use

The operative question: does this expenditure restore the property to its prior condition, or does it extend the property's useful life beyond what it would have been? The latter is capital.

3. Flag large one-time items on your statement

Go through your reconciliation statement line by line and mark any item that:

Is a round number above your lease's threshold (e.g., $47,500, $120,000)
Appears only in one year, not as a recurring annual cost
Has a category name associated with major building systems: roof, HVAC, elevator, parking, plumbing main lines, electrical panels

Common CapEx-disguised-as-OpEx descriptions to watch for:

"Roof maintenance" (may actually be full replacement)
"HVAC repairs" (may be full unit replacement)
"Parking lot maintenance" (may be full repaving)
"Elevator service" (may be full modernization)
"Building systems" (catch-all for unlabeled improvements)

Any of these exceeding your threshold warrants an invoice request.

4. Look for vague descriptions specifically

Precise descriptions — "replace broken window, Unit 12, $340" — are typically routine repairs. Vague descriptions are the ones to investigate. "Building improvements — $68,400" tells you almost nothing. That's where CapEx tends to hide, either because the landlord is deliberately opaque or because the property management system isn't set up to distinguish categories clearly.

Flag every line item with a vague description above your lease's threshold and request supporting documentation for all of them.

5. Request invoices for any item over threshold

Send your audit rights request (see the guide on how to request CAM documentation) and specifically include: "All invoices, contracts, and work orders supporting any single Operating Expense line item exceeding $[threshold]."

The invoice is where you get the information you need. A proper invoice will describe the scope of work. "Replace 14 HVAC units, building-wide" is different from "repair compressor, Unit 7A." The former is almost certainly capital; the latter is likely a repair.

6. Apply the repair vs. replacement test to each invoice

When you have the invoice, ask three questions:

Does this fix a broken component, or replace the entire system? A broken compressor is a repair. Replacing all HVAC units is capital.
Does this restore the property to its prior condition, or does it extend the useful life? Patching a roof section is repair. Installing a new roof is capital.
Would an accountant capitalize this on a balance sheet? If the landlord's own accountants would treat it as a capital asset with depreciation, it shouldn't be in your CAM charge.

The IRS "betterment, restoration, or adaptation" framework (IRC § 263 and the UNICAP regulations) is the most reliable external standard if your lease doesn't define its own test.

7. Apply the IRS CapEx standard: replacements that extend useful life are capital

Under the IRS "unit of property" test, if the work replaces a major component or substantial structural part of a building system, it's a capital expenditure — not a deductible repair. This applies to:

Roof (structural component)
HVAC system (building system)
Plumbing main lines (building system)
Electrical system (building system)
Elevators (structural component)
Parking lot (structural component)

If the invoice shows replacement of an entire system or major component, that's CapEx by IRS standards. Even if the landlord calls it "maintenance," the substance controls.

8. Calculate your share of confirmed CapEx pass-throughs

Once you've confirmed a CapEx charge was passed through to CAM, calculate what you overpaid:

Identified CapEx amount in CAM pool: $68,400 Your pro-rata share: 9.96% Your portion of the CapEx pass-through: $68,400 × 9.96% = $6,813

That's your overcharge for that item. Repeat for each confirmed CapEx item. Sum them for your total dispute amount. Use exact math — the dispute letter you'll send requires specific dollar figures, not estimates.

"I built CAMAudit because CapEx buried in CAM is both common and hard to catch without seeing the invoices. Our tool flags large one-time items for manual review and cross-references them against your lease's exclusion language." — Angel Campa, Founder of CAMAudit

Common Mistakes

Only reviewing items the landlord describes as "capital." Landlords who pass through CapEx improperly don't label it capital. Check every large, vague, one-time line item regardless of how it's described.

Accepting summary reports instead of invoices. A summary line showing "$68,400 — building maintenance" doesn't tell you what the work was. Insist on the invoice for anything over your lease's threshold.

Not checking amortized CapEx. Some landlords spread CapEx over multiple years, charging tenants a fraction annually. The underlying expense is still CapEx, even amortized. If you see a recurring line item described as "capital improvement amortization," check whether your lease allows amortized CapEx pass-throughs at all — many don't.

FAQ

My lease says CapEx is excluded "except as amortized over the useful life." What does that mean? Some leases allow landlords to pass through CapEx on an amortized basis — essentially, spreading the cost over the item's IRS-determined useful life. If this language is in your lease, the landlord can charge you a fraction of the CapEx each year. Check whether the amortization schedule matches IRS guidelines and whether the useful life used is reasonable. A 10-year roof shouldn't be amortized over 5 years.

What if the landlord claims a roof replacement was a "repair" because only part of the roof was replaced? The analysis depends on how large a portion was replaced. Replacing 10% of a roof to fix storm damage is likely a repair. Replacing 80% of a roof is likely capital regardless of how it's described. Courts look at the scope and the functional result — did the property end up with something substantively better or longer-lasting than what it had before?

How do I dispute a CapEx charge once I've confirmed it? Document the finding with the invoice and your lease's exclusion language. Calculate the exact dollar overcharge using your pro-rata share. Then follow the dispute process — a written letter citing the specific lease clause, the invoice date, the expense amount, and the dollar discrepancy. CAMAudit generates a dispute letter draft with your lease citations included once the audit is complete.
