Triple Net Lease vs Gross Lease: What’s the Difference?
When comparing a triple net lease vs gross lease, the key difference is who pays operating expenses.
In a gross lease, most property expenses are included in the rent. In a triple net (NNN) lease, tenants pay base rent plus property taxes, insurance, and common area maintenance (CAM).
Tenants comparing a triple net lease vs gross lease are often deciding between predictable rent and variable operating expense exposure.

Financial Impact for Tenants
In a triple net lease, operating expenses can increase 15–35% above base rent depending on taxes, insurance rates, and CAM budgets.
Without proper caps or audit rights, tenants may face rising costs that were not fully anticipated at signing.
Many disputes arise during CAM reconciliation when annual expenses are finalized.
Where Overcharge Risk Appears
- Improper allocation of shared expenses
- Capital improvements billed as operating costs
- Administrative markups on CAM
- Charges exceeding lease‑defined caps
Understanding the difference between a triple net lease and gross lease helps tenants evaluate risk — but reviewing the actual lease language is what protects you.
