Rentable Area (Concept)

Building owners, architects, and appraisers use the rentable area in analyzing the economic potential of a building. Tenants use the rentable area for lease verification and negotiation.

The rentable area of a floor is fixed for the life of a building and is not affected by changes in corridor size or configuration.

How it is Calculated

A floor’s rentable area is calculated by subtracting the vertical penetration area from the internal gross area.
