Lease Types

Modified Gross Lease

Also known as: modified net lease

Definition

A modified gross lease is a commercial lease that splits operating costs between landlord and tenant. The tenant pays a base rent that includes some expenses, while others, such as utilities or janitorial, are paid separately. It sits between a full gross lease and a triple net lease.

A modified gross lease is a middle-ground structure. It blends the simplicity of a gross lease with the cost-sharing of a triple net lease. The landlord bundles some operating costs into the base rent, and the tenant pays the rest separately.

What’s typically included vs. separate

The split is negotiated lease by lease, but a common arrangement is:

Included in base rentPaid separately by tenant
Property taxesElectricity / gas
Building insuranceJanitorial for your unit
Structural maintenanceSometimes a share of CAM

The catch for small businesses

“Modified” gives landlords room to define exactly which costs you carry, and those costs can still change year to year. You get fewer pass-throughs than NNN, but the total is still not fully predictable.

WareSpace keeps it simple with a fully all-inclusive rate: docks, HVAC, utilities, security, and maintenance in one flat monthly number. Compare structures in our cost-to-rent guide or get an instant quote.

Frequently asked questions

What is the difference between a modified gross and a triple net lease?
In a triple net lease the tenant pays base rent plus taxes, insurance, and CAM separately. In a modified gross lease the landlord covers some of those costs inside the base rent while the tenant pays others, so fewer expenses are passed through.
Who pays utilities in a modified gross lease?
It varies by lease. Often the tenant pays their own utilities and janitorial while the landlord covers taxes, insurance, and structural maintenance. The exact split is negotiated, so always read which expenses are included.
