See How It WorksSee a sample report firstNorth Carolina's commercial real estate market has seen extraordinary growth over the past decade. Charlotte's Uptown and South End corridors, the Research Triangle's office parks in Raleigh, Durham, and Chapel Hill, Greensboro's industrial and retail base, the Wilmington coastal market — all of them run on triple-net and modified-gross leases that pass common area maintenance costs to tenants. And across all of those markets, CAM billing errors are a consistent, underaddressed problem.
40% of CAM reconciliations contain material errors (Tango Analytics / PredictAP, 2023)
I built CAMAudit partly because growth markets like Charlotte and Raleigh attract institutional landlords managing large portfolios with centralized accounting systems. Those systems are efficient, but efficiency does not equal accuracy. Our tool has flagged management fee overcharges, pro-rata share errors, and CapEx misclassification in North Carolina-style reconciliation statements. The pattern is consistent with what we see nationally.
North Carolina's statute of limitations is among the shorter in the Southeast — 3 years. Acting promptly is not optional here.
North Carolina's statute of limitations for written contract claims is 3 years under N.C. Gen. Stat. § 1-52(1). The clock runs from the date of breach — typically the date each improper CAM charge was billed or collected.
Three years is a tight window for commercial tenants. The CAM reconciliation cycle typically closes 3–6 months after the lease year ends. If your landlord issued a 2023 reconciliation in mid-2024, the clock on those charges runs through mid-2027. Charges billed before mid-2023 may already be outside the recovery window.
This short SOL makes North Carolina one of the states where timing matters most. A tenant who discovers potential overcharges in year 4 of a 5-year lease and delays acting will find that charges from years 1 and 2 are already time-barred.
Lease contracts add another layer of deadline: most North Carolina commercial leases contain a contractual challenge window of 60 to 180 days after the annual reconciliation statement is delivered. Courts enforce these conditions as binding contractual obligations. Missing the lease window can bar a claim even if the statutory SOL has not run.
North Carolina has no state statute granting commercial tenants the right to audit CAM records. The North Carolina residential landlord-tenant statutes (N.C. Gen. Stat. § 42-1 et seq.) apply only to residential tenancies. Commercial tenants' audit rights exist only if the lease creates them.
Under North Carolina contract law, commercial leases are interpreted as contracts. The landlord bears the burden of proving that each CAM charge is authorized by the lease. This principle does not create a right to inspect books, but it does mean that a landlord who cannot substantiate a charge in response to a written demand has a weak position in any dispute.
A standard North Carolina commercial audit clause will include a defined challenge window, the right to inspect books and records (typically limited to 24 months of records), auditor qualification requirements, and cost allocation provisions. Without an audit clause, your options are limited to written demands for documentation and, if the landlord does not cooperate, litigation discovery.
Charlotte's commercial market is anchored by Uptown's Class A office towers, the South End retail and mixed-use district, the SouthPark mall area, and extensive suburban office and retail development in Ballantyne, University City, and the Lake Norman corridor. Several overcharge patterns appear consistently in Charlotte-area CAM statements.
Management fee overcharges. Charlotte's institutional landlords — national REITs and large regional property management companies — commonly charge management fees at 3–5% of operating expenses. The overcharge typically comes from an incorrectly defined fee base. When the fee is calculated against total building revenues (including taxes, insurance, and pass-through utilities) rather than the controllable operating expense pool the lease specifies, the effective fee rate exceeds the cap. On a $3 million CAM pool, a 1% fee overcharge is $30,000 per year across all tenants.
CAM cap violations. Charlotte retail leases frequently include CAM caps limiting annual controllable expense growth to 3–5%. The 2021–2023 inflationary period produced widespread cap violations in Charlotte as property management costs rose faster than caps allowed. CAMAudit's CAM cap detection rule reconstructs the allowed ceiling from lease inputs and identifies any year where billed controllable expenses exceeded the permitted maximum.
Landlord overhead pass-throughs. Charlotte's large institutional landlords sometimes allocate corporate overhead, regional management costs, or portfolio-level administrative expenses to individual property CAM pools. Lease language typically permits property-level management fees — not corporate overhead. CAMAudit's landlord overhead detection rule classifies each fee category against the lease's permitted expense definitions.
The Research Triangle's commercial market is characterized by Class A office parks serving the technology and pharmaceutical sectors, retail corridors along North Hills and North Raleigh, and a dense network of mixed-use developments in downtown Durham and Chapel Hill. CAM issues in this market reflect its institutional ownership profile.
Pro-rata share denominator errors. Research Triangle office parks frequently include anchor or major tenants paying fixed CAM contributions rather than pro-rata shares. When anchor square footage is included in the denominator used to calculate other tenants' pro-rata shares, the result depends on whether there is a corresponding gross-up provision — the arithmetic is fact-specific to each lease. CAMAudit's pro-rata share rule reconstructs the correct denominator and checks the resulting share against what was billed.
Base year manipulation. For leases with expense stops, the base year determines the tenant's threshold. Leases executed during the 2020–2021 period — when building operating costs were suppressed by low occupancy — may reference a base year that understates normal operating expenses. As the building returns to full occupancy, the annual pass-through grows faster than a normalized base year would produce. CAMAudit's base year detection rule models the correct base year expense level and identifies whether the baseline has been set abnormally low.
Gross-up errors. Gross-up provisions that normalize variable expenses to a standard occupancy level are frequently misapplied in Triangle office leases. Applying gross-up to fixed costs (property taxes, insurance) improperly inflates those line items. Failing to apply gross-up to variable costs during low-occupancy years inflates each tenant's share of those costs. CAMAudit's gross-up detection rule identifies both error types.
Across both Charlotte and the Research Triangle, as well as secondary markets like Greensboro, Winston-Salem, and Wilmington, capital expenditure misclassification is a widespread problem. Roof replacements, HVAC overhauls, parking lot resurfacing, and elevator modernizations should be either excluded from CAM or amortized over useful life under standard lease language. Landlords who charge these costs as single-year operating expenses are violating this provision. CAMAudit's CapEx classification rule identifies line items that appear to be capital improvements based on their description, amount, and comparison to prior-year costs.
North Carolina's commercial CAM dispute process is entirely contractual. No state agency handles these disputes. The path runs from your lease's audit clause through demand letters to negotiation and, if necessary, North Carolina Superior Court.
Step 1: Identify every deadline in your lease. North Carolina commercial leases commonly impose challenge windows of 60 to 120 days after the annual reconciliation is delivered. Note the exact deadline — including how "delivered" is defined in the lease's notice provisions — before doing anything else. Missing the contractual window can eliminate your right to dispute that year's charges.
Step 2: Send a written documentation request via certified mail. Reference your audit clause specifically. Request the general ledger backup, invoices for questioned items, the management fee calculation worksheet, and the pro-rata share allocation for the building. Certified mail with return receipt creates the delivery record you will need if the dispute escalates.
Step 3: Run CAMAudit on your lease and CAM statement. The platform applies all 14 detection rules and returns a findings report identifying each suspected overcharge with the specific lease provision being violated and the arithmetic demonstrating the discrepancy. The report is the foundation of your formal dispute letter.
Step 4: Send a formal dispute letter. The dispute letter draft should identify each overcharge claim specifically: the line item, the amount billed, the amount permitted under the lease, and the arithmetic showing the discrepancy. Set a 30-day response deadline and send via certified mail, return receipt requested.
Step 5: Negotiate or escalate. Charlotte and Raleigh institutional landlords typically have professional property management and legal teams. Well-documented disputes often resolve with credits or refunds. If the landlord refuses to engage substantively within the response window, engaging a North Carolina commercial real estate attorney and considering a Superior Court filing is the appropriate next step.
North Carolina landlords managing professionally operated commercial assets typically acknowledge dispute letters within 2–3 weeks. A substantive response usually follows within 30–60 days, often after the property manager has escalated to the landlord's legal counsel and accounting team.
The response will concede specific items, offer a partial credit, reject the claim outright, or propose a global settlement covering multiple years. Partial concessions are common — landlords who review their own records in response to a dispute sometimes identify errors they were not previously tracking.
If the landlord concedes, document the settlement in writing: a credit memo or lease amendment specifying the amount, application period, and any mutual release language.
If the landlord rejects your claim, assess the strength of your documentation. A CAMAudit findings report with specific lease citations and arithmetic is the kind of evidence that makes litigation credible and encourages settlement. North Carolina courts apply standard contract interpretation principles: the lease language controls, ambiguities in landlord-drafted documents can be construed against the drafter, and the burden of proving each charge is authorized rests on the landlord.
Prejudgment interest in North Carolina accrues at 8% per annum under N.C. Gen. Stat. § 24-1 (or the contract rate if specified). On a $25,000 overcharge that takes 18 months to resolve, interest adds $3,000 to the landlord's exposure — a meaningful settlement incentive.
North Carolina's SOL for written contract claims is 3 years under N.C. Gen. Stat. § 1-52(1). This is among the shorter statutes in the Southeast, and it makes acting promptly especially important. The clock runs from the date of each breach — when each improper CAM charge was billed or collected. A tenant auditing today can only recover overcharges from the past 3 years. Lease-defined challenge windows are typically shorter still and act as additional, earlier deadlines.
No. North Carolina's landlord-tenant statutes (N.C. Gen. Stat. § 42-1 et seq.) apply to residential tenancies. There is no North Carolina statute granting commercial tenants a statutory right to audit CAM records. Your right to inspect the landlord's books depends entirely on your lease's audit clause. Without an audit clause, you can demand documentation in writing and dispute charges under general contract law, but you cannot compel access to the landlord's accounting records without litigation discovery.
The most common pattern in Charlotte is the fee base expansion: the management fee percentage is applied to total building revenues (including taxes, insurance, and utilities) rather than the controllable operating expense pool defined in the lease. A 4% fee on $4 million in total revenues is $160,000; a 4% fee on $800,000 in controllable operating expenses is $32,000. The difference — $128,000 spread across the building's tenants — is the overcharge. CAMAudit's management fee detection rule identifies this pattern by tracing the fee back to the lease's specific base definition and calculating what the fee should be.
No — in fact, end-of-lease is a common trigger for CAM audits because landlords sometimes issue final reconciliation statements with errors, and tenants become more motivated to recover money before vacating. However, North Carolina's 3-year SOL and your lease's contractual challenge windows both apply. For a lease expiring in 2026, charges billed in 2022 and earlier may already be outside the statutory window depending on when they were issued. Charges from 2023 onward should still be recoverable. Run CAMAudit on your most recent 2–3 years of CAM statements to identify overcharges while recovery is still possible.
