Floor Area Ratio

« Back to Land-Use Planning Dictionary

FAR is the ratio of a building’s total floor area to the area of the lot on which the building stands. The gross floor area permitted on a site divided by the total net area of the site, expressed in decimals to one or two places. For example, on a site with 10,000 net square feet of land area, a floor area ratio of 1.0 will allow a maximum of 10,000 gross sq. ft. of building floor area to be built. 0n the same site, an FAR of 1.5 would allow 15,000 sq. ft. of floor area; an FAR of 2.0 would allow 20,000 sq. ft.; and an FAR of 0.5 would allow only 5,000 sq. ft. Also commonly used in zoning, FARs are typically applied on a parcel-by-parcel basis as opposed to an average FAR for an entire land use or zoning district.
