Gross Floor Area
The gross floor area is the total floor area (measured in square feet or meters) of all floors in the building that you would like considered in your valuation. This includes stairwells and elevator shafts, but does not include areas such as basements and mezzanines.
A one-story building with exterior wall dimensions of 100' x 100' has a gross floor area of 10,000 square feet. If the same building had three-stories, the gross floor area would be 30,000 square feet. If the first two stories were 10,000 square feet each and the third floor was 5,000 square feet, then the gross floor area would be 25,000 square feet.
- To determine the gross floor area, you first need to calculate the ground floor area. For a valuation to be accurate, proper determination of the floor area is crucial.
- After you calculate the individual ground floor areas, compute gross floor area by multiplying the ground floor area by the total number of stories.
