the sum of the area of all of a building's floors existing within its exterior walls. A municipal zoning ordinance may define gross floor area as extending to the outer surface of the exterior walls; in commercial leasing, however, gross floor area is measured to the inside finish of these walls.
A total of all the floor area above grade measured from the outside walls.
The area within the perimeter of the outside walls of a building taking into account the number of stories contained in the structure. Space used for interior features, such as stairwells and elevator shafts, is included in the gross floor area.
Covered floor space (whether within or outside a building and whether or not enclosed) measured between party walls including thickness of external walls and any open area used for commercial purposes.
The sum of the floor areas of the spaces within the building including basements, mezzanine and intermediate-floored tiers, and penthouses with headroom height of 7.5 ft or greater. It is measured from the exterior faces of exterior walls or from the centerline of walls separating buildings, but it excludes covered walkways, open roofed-over areas, porches and similar spaces, pipe trenches, exterior terraces or steps, chimneys, roof overhangs, and similar features.
The total floor area contained within the outermost walls, roof and lowest floor level of any building.
In the Seattle Municipal Code this refers to the number of square feet of total floor area bounded by the inside face of the outside wall of the structure, measured at the floor line. Referred to as GFA.
The measurement of the total floor area in a building, including core spaces, common areas and vacant spaces.
The total (usable) area of all floors of a building; it is the total floor space including the thickness of external walls (incl. plaster or other cladding).
the total floor area of a building measured from the outside of the external walls, plus for roofed unenclosed areas, any portion of floor area beyond a distance of 3 metres from the external wall. It does not include the area of spaces used for the parking of motor vehicles.
means the total area of all the floors in each building on a lot, measured to the extreme outer limits of each building. See the Cityâ€(tm)s Zoning Bylaw for a more detailed definition.
