The actual physical space a tenant exclusively occupies for their business operations, measured to the interior walls of the leased premises.
USF represents the real footprint where the tenant places desks, inventory, and equipment. It excludes shared areas like lobbies, elevators, and restrooms. Space planners use USF to determine whether a company's headcount will fit in a suite. While the landlord advertises and charges rent based on the larger RSF figure, the ratio of USF to RSF (the "efficiency ratio") reveals how much non-usable space the tenant is paying for. Older buildings with large lobbies tend to have higher load factors and lower efficiency.
