When evaluating commercial real estate, the quoted rent is only one part of the total occupancy cost. Two

properties with similar rental rates can create very different financial obligations depending on how the lease

allocates property taxes, insurance, maintenance, utilities, and other operating expenses.

Understanding the difference between gross, modified gross, and net leases allows a tenant to compare

alternatives more accurately and avoid unexpected costs after the lease is signed.

What Is a Gross Lease?

In a gross lease, the tenant generally pays one rental amount while the landlord pays most of the property’s

operating expenses. Depending on the agreement, those expenses may include real estate taxes, building

insurance, common-area maintenance, and certain utilities.

The primary benefit to the tenant is predictability. A single rent figure can simplify budgeting and reduce direct

exposure to changes in building expenses. However, “gross” does not necessarily mean that every cost is

included. Tenants may still pay for electricity within the premises, internet service, janitorial work, repairs caused

by their operations, or other specifically identified expenses.

Some gross leases also contain a base-year provision. Under this structure, the landlord pays operating expenses

up to the amount incurred during an established base year, while the tenant pays its proportionate share of

increases in later years.

What Is a Modified Gross Lease?

A modified gross lease combines elements of both gross and net structures. The landlord and tenant divide

responsibility for operating expenses according to the negotiated terms of the lease.

For example, the landlord may pay property taxes, building insurance, and structural repairs, while the tenant pays

utilities, interior maintenance, and janitorial expenses. In another transaction, the tenant may be responsible for

increases in operating expenses above a base year.

Modified gross leases are common because they allow the parties to tailor the expense allocation to the property

and the transaction. That flexibility also means the term itself provides limited guidance. Two leases described as

“modified gross” may allocate costs very differently, so the actual lease language is more important than the label.

What Is a Net Lease?

In a net lease, the tenant generally pays base rent plus some or all of the property’s operating expenses. These

additional amounts are often referred to as pass-through expenses or additional rent.

The three expenses most commonly associated with net leases are property taxes, building insurance, and

common-area maintenance. A single-net lease may pass through property taxes. A double-net lease may add

insurance. A triple-net lease generally requires the tenant to pay its proportionate share of all three categories.

Because more expenses are passed through to the tenant, the stated base rent may appear lower than the rent

under a gross lease. That does not necessarily make the net lease less expensive. The total cost depends on the

base rent, current pass-through expenses, annual increases, administrative fees, capital expenditures, and the

specific exclusions or limitations contained in the lease.

Why Lease Structure Matters

Lease structure affects both cost and risk. A gross lease may provide greater predictability, while a net lease may

expose the tenant to increases in taxes, insurance premiums, maintenance expenses, and other property-level

costs. A modified gross lease can fall anywhere between those two approaches.

Before comparing properties, tenants should estimate the total occupancy cost for each alternative. The review

should include:

 Base rent and scheduled rent increases

 Operating expense pass-throughs and base-year adjustments

 Utilities, parking, insurance, and maintenance obligations

 Administrative or management fees

 Capital expenditures and major repair responsibilities

Questions to Ask Before Signing

The lease should clearly identify which expenses are included in rent, which are billed separately, and how the

tenant’s share is calculated. Tenants should also determine whether expense caps, exclusions, audit rights, or

reconciliation procedures apply.

The most useful question is not simply whether a lease is gross, modified gross, or net. The better question

is: Which expenses will the tenant pay, how will those expenses be calculated, and how could they change over

the lease term?

A knowledgeable commercial real estate advisor can help a business evaluate these provisions, compare total

occupancy costs, and negotiate a lease structure that supports both current operations and long-term objectives.
