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.

Retail Net Lease (NNN Retail): CAM Audit Guide

Last updated: April 2026

By Angel Campa, Founder

Retail Net Lease (NNN Retail) tenants face specific billing risks tied to how expenses are allocated and reconciled. The most common error appears in the section below. CAMAudit runs 14 forensic detection rules on your reconciliation statement to identify every recoverable dollar.

Most Common Overcharge

Structural repair and replacement costs billed as maintenance, particularly parking lot mill-and-pave (which is a capital replacement, not repair) and roof replacement billed as "patching." Property tax increases driven by a sale of the property at a capitalized value well above assessment (sale-triggered reassessment in some states) can also generate sudden, large pass-through increases.

What Is a Retail Net Lease (NNN Retail)?

A specialized variant of the Triple Net lease structure optimized for single-tenant retail properties, often freestanding pad sites or anchor-equivalent standalone buildings leased to investment-grade retailers (pharmacy chains, dollar stores, auto parts retailers, fast food franchises). These leases typically feature long initial terms (10 to 20 years), minimal landlord obligations, and corporate guarantees from the tenant's parent entity.

Retail Net Lease (NNN Retail) Expense Pass-Throughs

Identical to standard NNN: tenant pays base rent plus pro-rata share of taxes, insurance, and CAM. In single-tenant retail net leases, the "pro-rata share" is effectively 100% since the tenant occupies the entire building. The tenant bears all operating expenses and, depending on the lease's classification as NNN vs. absolute net, may also bear structural costs.

Retail Net Lease (NNN Retail) CAM Calculation & Billing

Because these are single-tenant buildings, there is no pro-rata share calculation, the tenant pays 100% of all expenses. Annual reconciliation compares estimated vs. actual total operating costs. Expenses are typically modest (no shared common areas) and dominated by property taxes, building insurance, and parking lot/exterior maintenance.

Red Flags to Watch

  • ▶Parking lot maintenance invoice for mill-and-pave (capital replacement, not repair)
  • ▶Property tax spike immediately following a sale of the property
  • ▶Roof "repair" invoice exceeding 30% of a full replacement cost estimate
  • ▶Management fee charged despite landlord performing no management functions

Audit Focus

Audit parking lot and exterior maintenance invoices for capital replacement masquerading as routine repair. Verify that property tax bills reflect the pre-sale assessed value, not a sale-triggered reassessment that substantially increases the tax base. Confirm roof repair invoices represent genuine partial repair and not a full membrane replacement.
