Common Area Misclassification: When Your CAM Bill Includes Costs That Are Not Operating Expenses

Angel Campa, FounderCAMAudit
Last updated: April 2026

A roof replacement billed as "roof maintenance," a parking lot repaving classified as "common area repairs," or a new HVAC unit listed as "HVAC service" all shift capital costs your landlord should absorb onto your monthly CAM bill. Capital costs misclassified as maintenance can add $20,000 or more to a single reconciliation.

Definition

Common Area Misclassification

Common area misclassification occurs when a landlord includes non-operating expenses in CAM by labeling them as routine maintenance or repairs. Capital improvements, replacements of building systems with a useful life exceeding a threshold defined in the lease or under IRS capitalization rules, leasing commissions, tenant improvement allowances, and construction costs are not CAM-eligible operating expenses in most commercial leases. The distinction matters because routine repairs are current operating expenses while capital expenditures benefit future periods and represent the landlord's investment in the property. Disguising capital costs as maintenance inflates the CAM pool and shifts the landlord's capital obligations to tenants who never agreed to fund them. CAMAudit's common area misclassification detection rule uses AI classification to evaluate each line item for signals of capital expenditure, including large one-time charges, system replacement language, new installations, and scope descriptions inconsistent with routine maintenance.

Key Takeaway

The line between "maintenance" and "capital improvement" is where some of the most common CAM overcharges hide. Replacing something is different from repairing it, and your CAM should only reflect repairs.

How CAMAudit Detects This

CAMAudit uses AI-powered classification to evaluate each line item in your CAM reconciliation for signals of capital expenditure disguised as operating expense. CAMAudit's common area misclassification detection rule looks for patterns associated with capital work: large one-time charges, system replacements, new installations, multi-year useful life assets, and work scope descriptions inconsistent with routine maintenance.

CAMAudit checks for leasing-related costs that sometimes appear in CAM under broad category labels: commissions, build-out costs, space planning fees, and tenant improvement work. These are categorically ineligible for CAM pass-through regardless of how they are labeled in the reconciliation.

CAMAudit notes the specific signals that triggered each flag such as large dollar amount, replacement language, or capital asset description so you can request the backup invoice and verify the actual nature of the work before submitting a formal dispute.

Real-World Example

A CAM reconciliation included $38,000 in "parking lot maintenance," $12,500 in "HVAC maintenance and upgrades," and $9,200 in "lobby improvements." CAMAudit flagged all three: the parking lot work was a full resurfacing (capital), the HVAC line included two new rooftop unit installations beyond routine service, and the lobby line referenced new flooring installation. Total potential capital expense in CAM: $59,700.

Recovery of past CAM overcharges depends on your specific lease terms, including any audit rights deadlines or ‘binding and conclusive’ provisions, and on applicable state law.

State statute of limitations periods apply to written contracts and range from 3 to 10 years. Your actual lookback window may be shorter based on your lease.
