What Are the Different Types of Commercial Real Estate Leases?

A commercial lease determines more than the monthly rent for a property. It also establishes how expenses, maintenance responsibilities, repairs, insurance, taxes, improvements, and other obligations are divided between the landlord and tenant.

Lease terminology is not always used consistently. Two leases described as “triple net,” for example, may assign different responsibilities to the tenant. The complete lease should therefore be reviewed rather than relying only on its general classification.

Understanding the basic lease structures can help business owners compare properties more accurately and help property owners determine how a space should be positioned and marketed.

Commercial leases generally fall into two broad categories:

Some leases combine features of both structures. These are often described as modified gross leases.

The lease structure affects the tenant’s total occupancy cost and the landlord’s net income. Comparing base rent alone may therefore provide an incomplete picture of the actual cost of leasing a property.

Under a gross lease, the tenant generally pays a fixed rental amount while the landlord pays the property’s primary operating expenses.

These expenses may include:

Gross leases can make occupancy costs more predictable for tenants because many expenses are included in the rent.

However, the landlord may account for those costs when establishing the rental rate. A gross lease may therefore have a higher base rent than a comparable net lease.

The lease should specify whether operating expenses are fully included or whether the landlord can pass along increases above an established base year or expense amount.

A modified gross lease divides property expenses between the landlord and tenant according to negotiated terms.

For example, the landlord may pay:

The tenant may pay:

There is no universal modified gross lease structure. The term simply indicates that the parties have divided expenses rather than assigning nearly all costs to one side.

Because these arrangements vary, tenants should request a clear breakdown of which expenses are included in the rent and which will be billed separately.

Under a single-net lease, the tenant generally pays base rent plus a share of the property taxes.

The landlord typically remains responsible for building insurance, maintenance, and other property operating expenses unless the lease states otherwise.

Single-net leases are less common than some other commercial lease structures, but they may be used when a landlord wants to pass through a specific property expense while retaining responsibility for most building operations.

Under a double-net lease, often written as an NN lease, the tenant generally pays:

The landlord commonly remains responsible for structural repairs and certain maintenance expenses.

As with any lease classification, the precise responsibilities depend on the written agreement.

Under a triple-net lease, commonly written as an NNN lease, the tenant generally pays base rent plus a proportionate share of:

Triple-net leases are common in retail, industrial, office, and single-tenant investment properties.

A lower advertised base rent does not necessarily mean the property will cost less to occupy. The tenant’s additional NNN expenses can substantially affect the total monthly payment.

Before signing, tenants should understand:

Property owners should maintain clear expense records and provide realistic estimates so tenants can evaluate the total occupancy cost.

An absolute net lease assigns nearly all property-related responsibilities to the tenant.

Depending on the agreement, the tenant may be responsible for:

Absolute net leases are most commonly associated with long-term, single-tenant properties.

They can provide predictable income and limited management responsibility for the landlord, but they also place substantial obligations on the tenant. The financial strength of the tenant and the condition of the property become particularly important in this type of arrangement.

A percentage lease requires the tenant to pay base rent plus a percentage of revenue generated at the property.

This structure is most often associated with retail properties.

The lease may establish:

Percentage leases allow the landlord to participate in the tenant’s business performance, while the tenant may benefit from a lower initial base rent.

The calculation and reporting terms should be clearly defined in the lease.

When comparing commercial spaces, tenants should evaluate the complete cost of occupancy rather than focusing only on the quoted rental rate.

Additional costs may include:

Commercial rental rates may also be quoted by the square foot on an annual or monthly basis. Tenants should confirm how the quoted rate is calculated and which measurement of the premises is being used.

Commercial rental rates may also be quoted by the square foot on an annual or monthly basis. Tenants should confirm how the quoted rate is calculated and which measurement of the premises is being used.

Common-area maintenance charges, often called CAM charges, cover expenses associated with operating and maintaining areas used by multiple tenants.

Depending on the property, CAM expenses may include:

The lease should explain how these costs are allocated among tenants.

A tenant’s share may be calculated according to the size of its premises compared with the total rentable area of the property. However, exclusions, vacancies, different building uses, and negotiated terms can affect the calculation.

Tenants should also determine whether CAM charges include capital improvements, administrative fees, or expenses that primarily benefit another tenant.

Repair responsibilities vary significantly among commercial leases.

The landlord may be responsible for:

The tenant may be responsible for:

A lease should clearly assign responsibility for routine maintenance, emergency repairs, major replacements, and building systems.

Tenants should inspect the property and evaluate the condition of major systems before accepting responsibility for them.

Tenant improvements are changes made to prepare a commercial property for the tenant’s use.

They may include:

The landlord may complete the improvements, provide an improvement allowance, reimburse the tenant, or deliver the space in its current condition.

The lease or a separate work agreement should address:

Improvement costs should be evaluated together with the rent and lease term. A lower-cost property may require substantial work before it can support the intended business use.

A landlord may require the business owner or another individual to personally guarantee the tenant’s lease obligations.

A personal guarantee may make the individual responsible if the business fails to pay rent or meet other lease requirements.

The guarantee may be:

The financial consequences can extend beyond the business itself. A tenant should understand the scope of a guarantee before signing it.

Before entering a commercial lease, a tenant should evaluate both the lease terms and the property’s suitability for the business.

Important considerations may include:

A property may appear suitable but still require planning approval, building permits, accessibility improvements, or substantial construction before the business can operate.

The intended use should be investigated before the lease becomes binding whenever possible.

A commercial lease should protect the property while also creating terms that qualified tenants can reasonably understand and satisfy.

Property owners may need to consider:

Clear lease terms and realistic operating-expense estimates can reduce misunderstandings during the tenancy.

Landlords should also consider how the property’s condition, configuration, location, parking, signage, and permitted uses affect its appeal to prospective tenants.

A commercial real estate broker representing a landlord can assist with:

Effective landlord representation involves more than advertising available square footage. The property must be positioned for the types of tenants whose needs, intended uses, and financial qualifications align with the space.

Commercial leases can vary considerably, even when they use the same general terminology.

Tenants should understand the complete cost of occupancy, confirm that the property can support their intended use, and obtain appropriate legal and professional guidance before signing.

Landlords should use clear lease terms, reliable expense estimates, and a marketing strategy designed to reach qualified tenants.
