Single Tenant

It seems logical and apparent that a landlord may or should use the exterior gross area when leasing an entire building to a single tenant. However the BOMA decriptions are not definitive in this regard (unless I am missing something, which is likely). Are we right to be recommending to our landlord client that she rent her building based on the EGA rather than an interior method?

In the case of a single tenant building, the landlord may use the Exterior Gross Area Method (EGA) if so desired. Keep in mind that EGA derives from the Gross Areas of a Building Standard and not from the 2010 Office Standard. The Standard that you choose should be clearly cited in all supporting documentation.

BOMA does not comment on the appropriateness of one standard over another. However, if you are making a recommendation to your client, consider that EGA does not accommodate multi-tenant leasing at all, so you want to think about the building's potential tenancy in the future. It can be tricky to change from one standard to another down the road.
