What is a triple-net lease?
Reviewed August 2026 by Shannon Miles Group
A triple-net (NNN) lease is a commercial lease structure that generally allocates certain property expenses to the tenant in addition to base rent. These expenses typically include property taxes, insurance, and maintenance or operating costs. However, the actual executed lease controls, and not all NNN leases allocate expenses identically. The term triple-net is used broadly in commercial real estate, but the specific expense allocation depends on the lease language. Some leases described as NNN may leave certain expenses with the landlord. Understanding the expense allocation in the actual lease is essential.
Understanding triple-net leases at a high level.
Triple-net leases are common in commercial real estate, but the term is used loosely. Here is a general overview of how these leases work and how they compare to other lease structures.
Gross lease
In a gross lease, the landlord pays most or all operating expenses from the rent collected. The tenant pays a fixed rent amount, and the landlord covers property taxes, insurance, and maintenance. Gross leases are more common in multifamily residential and some office leases.
Modified gross lease
In a modified gross lease, the landlord and tenant share certain expenses. The specific allocation varies by lease. For example, the tenant might pay utilities and janitorial services while the landlord pays taxes, insurance, and structural maintenance. Modified gross leases fall between gross and triple-net structures.
Triple-net (NNN) lease
In a triple-net lease, the tenant generally pays property taxes, insurance, and maintenance or operating costs in addition to base rent. The landlord's expense responsibility is typically limited to structural repairs, roof, and parking lot in some cases. However, not all NNN leases are structured the same way. Some NNN leases require the tenant to pay all expenses. Others allocate certain capital expenses or structural maintenance to the landlord. The actual lease language controls.
Why the label matters less than the lease language
Two properties both described as triple-net could have very different expense allocations. The term NNN is a shorthand, not a legal definition. A buyer or tenant should always read the actual lease to understand who pays for what. Do not rely on the label alone. Commercial real estate leases are negotiated documents, and the terms vary widely.

NNN leases in Northeast Texas.
Lease structures vary by property type and market in Northeast Texas. Retail properties in Paris, Sherman, and Greenville may use NNN leases. Office and industrial properties may use modified gross or full-service leases. The local market convention for a particular property type may influence the lease structure, but every lease is individually negotiated.
Rural commercial properties may have lease provisions that differ from urban commercial leases, such as well and septic maintenance, road maintenance, or agricultural use restrictions. Understanding the expense allocation in the actual lease is essential regardless of the label used.

Key points about NNN leases.
- The label is not a definition. Two properties both described as NNN can have very different expense allocations. Read the actual lease.
- Understand who pays for what. Taxes, insurance, maintenance, utilities, structural repairs, and capital expenses each may be allocated to the landlord or tenant.
- Compare gross, modified gross, and NNN. Each structure shifts different expense risks between landlord and tenant.
- Consult a commercial real estate attorney. Lease review is important for buyers and tenants. Do not rely on a verbal description of the lease terms.
