Understanding NNN Leases: A Guide for Tenants

2026-01-08

Commercial leases can be complex, especially when you encounter the term NNN or "Triple Net Lease."

What is a Triple Net Lease?

In a Triple Net Lease, the tenant agrees to pay not only the base rent but also:

  1. Property Taxes (N)
  2. Insurance (N)
  3. Maintenance (N)

This structure lowers the base rent for the tenant but shifts the risk of operating costs.

How to Calculate Your Total Cost

To understand your total monthly obligation, you need to sum up your base rent per square foot and your estimated NNN charges per square foot.

Tip: Always ask for the historical CAM (Common Area Maintenance) charges before signing.
