(AKA RBA) Expressed in square feet, this area includes the usable area and its associated share of the common areas. Typically rents are based on this area. It is the space the tenant will occupy in addition to the associated common areas of the building such as the lobby, hallways, bathrooms, equipment rooms, etc. There is no real difference between RBA and GLA (Gross Leasable Area) except that GLA is used when referring to retail properties while RBA is used for other commercial properties.
