(AKA GLA) Expressed in square feet. It is the total floor area designed for the occupancy and exclusive use of tenants, including basements and mezzanines. It is the standard measure for determining the size of retail spaces, specifically shopping centers, where rent is calculated based on GLA occupied. There is no real difference between RBA (Rentable Building Area) and GLA except that GLA is used when referring to retail properties while RBA is used for other commercial properties.
