Gross Rentable Area

We have a project where the lease is based on Gross Rentable area. Building is a two story multi-tenant office building. Would this building be calced per office standard method A only using the building exterior gross area in lieu of interior gross area?

Hi Richard,

The 2010 Office Standard is intended for calculating Rentable Area only, according to Method A or Method B, as prescribed. The standard does not define either "Gross Rentable Area" or "Exterior Gross Area", so be careful interpreting and utilizing these terms. EGA is defined in the Gross Areas of a Building Standard (a totally separate standard) and has no place in Rentable Area calculations.

Assuming that Gross Rentable means the aggregate of all Rentable Areas in the building, you should use the Total Rentable Area (last row, column Q of the BOMA 2010 Method A).
