If you are looking for office space for your business, you'll be talking to commercial real estate people. Like other professions, they throw out terms like everyone is supposed to know what they are talking about.

To help you navigate the real estate jargon and terms you will see in a commercial lease, here are some common office and commercial leasing terms and their general explanations. Some of these terms may be used differently in various regions of the country, so be sure to ask the precise meaning of a term when you are negotiating a lease.


The lessor is the person who is granting the lease and who has the legal obligations related to the lease contract; the landlord. Sometimes this is an owner, but it may also be a property management company or commercial leasing company.


The lessee is the person leasing the space; the tenant. Although you may need to personally guarantee a lease, your business entity should be the official lessee on all documents relating to the lease.

Common Area Maintenance (CAM)

This term describes costs for areas in a building that are not directly leased but which are a common responsibility, such as hallways, restrooms, stairways, and walkways. Most lessors add CAM costs to square footage costs to calculate lease payments.

Fully Serviced Lease

A lease in which the rental payment includes other services, such as utilities, maintenance, and lawn/snow removal services. The landlord pays these fees and passes them on to the tenants in the lease. This can be a benefit to tenants as it saves from having to pay these additional fees, but the landlord may be charging more than actually is being paid for these services.

Gross Lease

A lease that includes the landlord agrees to pay for all common expenses, including utilities, repairs, insurance and (occasionally) property taxes. The cost of a gross lease is higher than for other types of leases because all of these items are included in the amount of the lease.

Net Lease

A lease which includes the square footage costs, CAM costs, and all other ownership expenses, including utilities, repairs, insurance, and property taxes.

Double Net Lease

A lease in which taxes and insurance expenses are included in the lease payment. The lessor pays maintenance costs.

Triple Net Lease

A lease which includes all taxes, insurance, and maintenance costs in the monthly payment.

Gross Square Foot

The total square footage of the building or office being leased. This figure usually includes common space. 


An abbreviation for 'heating, ventilating, and air conditioning.' It's often pronounced as "H-VAC." 

Build-out/Leasehold Improvements/Tenant Improvements

The improvements to the office or building to make it usable for the tenant. In accounting terminology, these costs are called "leasehold improvements," and they can be depreciated as expenses.


An office or building that is ready to occupy. In most cases, this is a commitment by the landlord to bear the cost of any build-out.


A sublease is an agreement between the lessor and lessee to allow someone else to use all or part of the space. In some cases, a business may wish to have another business to share the space - and the rent. In other cases, the tenant may want to leave before the lease term is up, and to have someone else take over the lease, to avoid having to re-negotiate.

Common Sections in a Commercial Lease Agreement

Premises. The detail of the building or unit, including the address, condition. Most commercial leases are made "as is," meaning that the lessee accepts the condition.

Lease term, usually expressed in months. This section includes both the date the lease is effective and the date the lessee begins to occupy the space.

Rent and payment. There may be a base rate and a separate CAM rate. This section describes when the rent is due, what happens if it's late,

Security deposit. This amount may be equal to the first month's rent, to be returned to the lessee at the end,

Rent adjustment explains when the rent might be adjusted for taxes, cost of living increases, or additional operating expenses.

Renewal option relates to how and when the tenant can renew the lease and any changes in rent for the additional terms.
