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.

CapEx vs OpEx in Commercial Leases

Last updated: April 2026

By Angel Campa, Founder

Capital expenses are long-term property investments that should not appear on your CAM reconciliation. Operating expenses are recurring costs that landlords can pass through.

Capital Expenses (CapEx)

Capital expenses are large, long-term investments in the property that extend its useful life or add value: roof replacements, HVAC system overhauls, parking lot repaving, or structural repairs. Under most lease terms, CapEx should not be passed through to tenants as operating expenses.

Advantages

  • ✓Should be excluded from tenant pass-throughs under standard lease terms
  • ✓Clearly distinguishable from routine maintenance by cost and scope
  • ✓Benefit accrues to the landlord through increased property value

Disadvantages

  • ✗Landlords sometimes amortize CapEx and pass the amortization through as an operating expense
  • ✗The line between capital improvement and major repair is often ambiguous
  • ✗Some leases explicitly permit CapEx pass-throughs for specific categories

Operating Expenses (OpEx)

Operating expenses are the recurring, day-to-day costs of running the building: maintenance, janitorial, landscaping, utilities, management fees, and routine repairs. These are the expenses that most leases allow landlords to pass through to tenants via CAM reconciliation.

Advantages

  • ✓Clearly defined as pass-through eligible under most lease structures
  • ✓Recurring nature makes them easier to budget and benchmark
  • ✓Smaller individual amounts are easier to verify against vendor invoices

Disadvantages

  • ✗Landlords may embed capital improvement costs within operating expense categories
  • ✗Many small charges make it harder to spot individual overcharges
  • ✗Total operating expenses can still increase significantly year over year

How This Affects Your CAM Charges

Capital expense pass-throughs are one of the most significant CAM overcharge categories. A landlord who includes a $200,000 roof replacement in the operating expense reconciliation can add thousands to each tenant's annual bill. Even when CapEx is amortized, the amortization may not be permitted under the lease. Every large or unusual line item on a reconciliation should be checked for CapEx classification.

Which Exposes You to More Risk?

Improperly passed-through capital expenses create larger individual overcharges than any other category. A single CapEx item can exceed an entire year's worth of operating expense overcharges combined. Tenants should treat any reconciliation line item over $10,000 as a potential CapEx pass-through that requires verification.
