Floor Area Ratio(FAR) = (Total cover area of all floors/  Plot area)

Floor area ratio for residential buildings is ranging from 1.0 to 2.0 depending on the type ‘of construction. It restricts the height of the building and number of storeys provided. For example, if a plot measures 15 m x 20 m and building bye-laws stipulates permissible FAR as 2.00, then the maximum built-up area which can be put on the plot is 600 m2. If the area covered at ground floor is 150 m2, the total number of floors that can be constructed is (600 / 150) = 4

Thus, with these bye-laws the height of the building cannot be more than 4 storeys. FAR is also used in classifying the type of construction on the basis of resistance offered by building against the fire
