What is an NNN Lease in Commercial Real Estate?

NNN Lease Overview

An NNN Lease, or Triple Net Lease, is a type of commercial real estate lease in which the tenant is responsible for paying three key expense categories in addition to their base rent:

  1. Net Property Taxes – The tenant pays its proportionate share of property taxes.
  2. Net Insurance – The tenant covers its share of building insurance.
  3. Net Common Area Maintenance (CAM) – The tenant contributes to costs for maintaining shared spaces, such as landscaping, security, and utilities.

How It Works:

  • The landlord typically passes these costs directly to the tenant, meaning the base rent appears lower than in a gross lease (where the landlord covers these expenses).
  • This structure is common in retail, industrial, and office properties, especially for single-tenant buildings.
  • Tenants prefer NNN leases when they want more transparency and control over operating costs, while landlords benefit from reduced financial responsibility.

Pros & Cons:✅ For Landlords:

  • Predictable income with fewer variable expenses.
  • Reduced risk from fluctuations in taxes, insurance, and maintenance.

For Tenants:

  • Greater control over property expenses.
  • Often lower base rent compared to gross leases.

Potential Downsides:

  • Tenants bear financial risk if operating expenses increase.
  • Requires careful lease negotiation to avoid excessive CAM charges.
