Double Net Lease (NN) 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.
Landlords slip structural repair costs into inflated insurance deductibles, particularly roof repairs. A landlord files an insurance claim for a roof leak, accepts a payout, but then passes the high deductible through to tenants as an "insurance expense." Tenants effectively subsidize capital repairs through a non-CAM channel.
A commercial lease structure where the tenant pays base rent plus their pro-rata share of property taxes and building insurance premiums. Unlike a Triple Net (NNN) lease, the landlord in a Double Net (NN) lease retains financial responsibility for common area maintenance, structural repairs, parking, landscaping, and all ongoing property upkeep. The tenant bears only two of the three "net" charges: taxes and insurance.
Tenant pays: base rent, property taxes (pro-rata), and building insurance premiums (pro-rata). Landlord pays: CAM expenses, structural maintenance, roof, parking lot, landscaping, janitorial of common areas, and all ongoing operating costs beyond taxes and insurance.
No traditional CAM reconciliation applies. Tenant receives annual property tax bills and insurance premium invoices, and pays their pro-rata share directly or through the landlord. Billed on the tenant's fractional share of the total municipal tax assessment and the building's insurance policy premium.
