Triple Net Lease Meaning (NNN Explained for Tenants)

What Is Included in a Triple Net Lease?

• Property Taxes – Your share of real estate taxes for the building or shopping center.
• Insurance – Landlord’s insurance premiums passed through to tenants.
• Common Area Maintenance (CAM) – Maintenance, landscaping, parking lot repairs, snow removal, and management costs.

Many tenants search for the triple net lease meaning expecting a simple definition. But the real financial impact depends on how these categories are defined inside your lease.

To understand how these categories are reconciled annually, review our CAM reconciliation guide, which explains how projected expenses compare to actuals.

Triple Net vs Gross Lease

In a gross lease, most operating costs are included in rent. In a triple net lease, those costs are separated and billed to tenants.

That structure shifts risk to the tenant — especially when expenses increase unexpectedly.

Expense volatility is often amplified by administrative layering and capital pass‑through language. See our CAM administrative fee analysis for common overcharge patterns.

For a full breakdown, see our CAM vs NNN guide.

Where Tenants Get Overcharged

• Capital improvements billed as operating expenses
• Administrative fees layered on top of CAM
• Improper pro-rata share calculations
• Charges exceeding lease-defined caps
• Expenses for vacant units allocated to active tenants

These issues are typically uncovered during CAM reconciliation review or a formal NNN audit rights exercise before the audit window closes.
