Introduction
Usable Area, often synonymous with Net Leasable Area, refers to the actual space within a property that can be utilized for its intended purpose. Unlike Gross Floor Area, which includes all parts of the building, Usable Area focuses on the space that can be directly used by tenants or occupants.
