Frequently asked questions
FAR is the ratio of total building floor area to the area of the land parcel. A 10,000 sq ft lot with a 2.0 FAR permits up to 20,000 sq ft of total building floor space.
Buildable Square Feet = Parcel Land Area (sq ft) × Floor Area Ratio (FAR).
It allows developers to compare the true development potential of different land parcels regardless of lot size or height limits.
