Assignable Square Footage (ASF) represents the usable portion of a building’s total square footage. This measurement focuses specifically on space that tenants and occupants can directly use for their daily operations and specific needs.
What ASF Includes
ASF includes functional spaces like offices, classrooms, retail areas, and laboratories. These areas serve a direct purpose for end users and contribute to productive activities within the building.
What ASF Excludes
ASF excludes common areas such as hallways, stairwells, mechanical rooms, and restrooms. These non-assignable spaces, while necessary for building function, cannot be used by tenants for their specific business purposes.
Commercial Building Example
Commercial office buildings calculate ASF by including private offices, conference rooms, and workstations. However, these buildings exclude lobbies and elevator shafts from ASF calculations since these areas serve the entire building rather than individual tenants.
Why ASF Matters
Understanding ASF benefits space planning efforts significantly.ASF knowledge improves leasing agreement negotiations by providing clear metrics for usable space. ASF calculations help determine building design efficiency by showing the ratio of usable to total space.
Practical Applications
ASF measurements assist tenants in evaluating available operational space.Property managers use ASF data to assess space utilization effectively. This information proves essential for making informed decisions about space allocation and rental arrangements.
