Question: can floor area be bigger than lot area

Answer: No, For example, if lot must adhere to a 0.1 FAR, then the total area of all floors in all buildings on the lot must be no more than one-tenth the area of the parcel itself. In other words, if the lot was 10,000 sq. ft, then the total floor area of all floors in all buildings mustn't exceed 1,000 sq. ft.
