The maximum size or gross area of a building on a lot is controlled also by the FAR or Floor Area Ratio. This is the ratio of the Gross Floor Area of all the buildings on a lot to the area of the lot. In cases in which portions of the gross floor area of a building project horizontally beyond the lot lines, all such projecting gross floor area are also included in determining the floor area ratio.

The way it is calculated is by multiplying the lot area to the FAR number corresponding with the assigned zoning of the lot.

Ex.: lot area = 3,000 sqft and FAR = 1.8

Maximum area of a building on this lot is 3,000 x 1.8 = 5,400 sqft
