Understanding Triple Net Leases (NNN)

Published on 24 June 2026 at 04:49

If you plan to lease retail, Class A medical, or industrial space, you have likely encountered the term triple net lease, abbreviated NNN. A clear understanding of this lease structure matters because it can substantially affect the total occupancy cost of commercial property.

What Is a Triple Net Lease?

A triple net lease requires the Lessee (tenant) to pay base rent plus certain operating expenses, including:

  • Property taxes

  • Property insurance

  • Common area maintenance (CAM) expenses

Under this structure, the Lessor (landlord) passes these expenses to the Lessee, who assumes responsibility for a significant portion of the property's operating costs.

How Does a Triple Net Lease Work?

Suppose a retail store leases 2,000 square feet at a base rate of $30 per square foot annually. In addition to base rent, the Lessee may pay:

  • Property taxes: $3.00 per square foot

  • Insurance: $0.75 per square foot

  • Common area maintenance: $2.25 per square foot

As a result, the Lessee's total occupancy cost equals $36 per square foot annually rather than the advertised $30 base rate.

What Are Common Area Maintenance (CAM) Charges?

CAM charges typically cover the upkeep and operation of shared areas, including:

  • Landscaping

  • Parking lot repairs and maintenance

  • Exterior lighting

  • Sidewalks

  • Trash collection

  • Security services

  • Ice and snow removal, where applicable

Most Lessees pay a pro rata share based on the amount of space they occupy.

Advantages for Lessors

Triple net leases offer several benefits to property owners:

  • More predictable income

  • Less exposure to rising operating costs

  • Protection from increases in property taxes and insurance premiums

  • Reduced day-to-day management responsibilities

Because the Lessee pays many operating expenses, the Lessor can focus on asset management and long-term value.

Advantages for Lessees

Triple net leases also provide advantages to tenants:

  • Lower base rental rates than full-service leases

  • Greater transparency regarding property expenses

  • More control over maintenance standards and operating costs

  • Access to professionally managed, high-quality properties

What Should Lessees Review?

Before signing a triple net (NNN) lease, tenants should review:

  • Which expenses CAM charges include

  • Whether the Lessor assesses management fees

  • Annual caps on controllable expenses

  • The method used to allocate taxes and insurance costs

  • Responsibility for repairs and replacements

  • Renewal options and rent escalations

A careful lease review helps tenants avoid unexpected expenses and confirm that occupancy costs align with their budgets.

Is a Triple Net Lease Right for You?

Triple net leases remain common in retail centers, Class A medical buildings, and industrial properties throughout the United States. They often offer flexibility and lower base rents. However, tenants should evaluate the total occupancy cost rather than focus solely on the advertised rental rate.

Whether you want to expand your business, open a new location, or invest in commercial real estate, a thorough understanding of triple net leases can help you make informed decisions and avoid costly surprises.
