Triple-Net Leases Move Operating Detail to the Foreground

In a gross lease, the landlord generally absorbs some operating costs within rent. In a triple-net lease, the tenant typically pays base rent plus a share of real estate taxes, property insurance, and operating or common-area maintenance costs. Modified gross leases split or base-year these costs, so the label alone is not enough.

What CAM May Include or Exclude

CAM may cover maintenance, landscaping, security, common utilities, management fees, and shared-area repairs. Review exclusions for landlord financing, leasing commissions, dispute costs, income taxes, penalties, capital improvements, depreciation, another tenant's costs, and amounts recovered from insurance or third parties.

Reconciliation, Audit Rights, and Caps

Confirm estimate timing, annual statements, backup records, audit rights, objection windows, management-fee limits, controllable-expense caps, and whether capital items are amortized. A cap without a clear base year or defined carve-outs may offer little protection.

Worth knowing: CAM is a contract category, not a universal accounting standard. The lease definition controls, and an estimate is not necessarily the final bill.
