Glossary Term Defined

The total of all the enclosed floor areas (as viewed on a floor plan) of all floors of a building contained within their measure lines, excluding voids (with the exception of occupant voids), interstitial space, unexcavated space and crawl space. No deductions are recognized for columns or any structural elements within the measure line.

The total floor area contained within the measure line (generally, the outside surface of the exterior enclosure of a building) including structured parking. Typically, unenclosed areas are excluded except for external circulation and the top level of a parking structure. It may be an appropriate measure of area for use in planning and design of buildings with respect to zoning floor area ratios (FAR), for real estate tax assessment purposes for some occupancies, for valuation using income or comparable value approaches, or for determining a lease rate when a building is leased to a single tenant.

The total of all the horizontal floor areas (as viewed on a floor plan) of all floors of a building contained within their measure lines, excluding voids (with the exception of occupant voids), interstitial space, unexcavated space and crawl space. Make no deductions for columns or any structural elements within the measure line.
