What is the definition of gross square feet in a building?

The definition of gross square feet in a building is the total area of all floors measured. This measurement includes every area within the outer walls of a building, encompassing not only the occupiable spaces but also the areas taken up by structural elements, such as walls and columns. It provides a comprehensive view of the building's total floor area, which is essential for various purposes, including real estate valuation, leasing, and compliance with local building codes.

The total area reflects the full extent of a building's size, making it a crucial metric for anyone analyzing property dimensions or planning renovations. Understanding gross square footage helps real estate professionals, landlords, and tenants assess the full scale of a building and its potential uses.
