A modified gross lease is a commercial lease in which the tenant pays a fixed base rent on a monthly or annual basis, but also agrees to pay a proportional amount of the operating expenses for the property, such as:

• taxes

• property insurance

• utilities

• maintenance and repairs (including structures such as the roof), systems (heating, ventilation, and air conditioning and electrical)

• common area maintenance (CAM) such as maintenance of the parking lot, landscaping, maintenance staff, security staff, and maintenance of elevators and escalators.

There are many variations of modified gross leases, with different expenses reimbursed by the tenant to the landlord, and different methods of calculating the tenant’s proportionate share of the expenses.

In New Hampshire, a modified gross lease is a type of commercial lease agreement where the tenant pays a set base rent plus a share of certain operating expenses for the property. The specific expenses covered by the tenant can vary, but they typically include property taxes, insurance, utilities, maintenance and repairs, and common area maintenance (CAM) costs. The exact terms of a modified gross lease, such as which expenses are included and how the tenant's share is calculated, are subject to negotiation between the landlord and tenant and should be clearly outlined in the lease agreement. It is important for both parties to carefully review and understand the terms of the lease, and they may seek the advice of an attorney to ensure that their rights and obligations are properly represented and to assist with any disputes that may arise from the lease terms.
