FAR is the relationship between the total square footage of a building and the total square footage of the parcel on which the building is located. It is typically calculated by dividing the total square footage of the building by the land area in square feet. For example, if a 20,000-square-foot building is built on a 10,000-square-foot lot, the FAR is 2.0.
