Floor Area Ratio (FAR)
Columbus City Codes § 3325.311
in effect3325.311 - Floor Area Ratio (FAR)
A. Floor Area Ratio defined. Floor area ratio (FAR) is a measure of intensity of development. FAR compares the floor area of a building to the area of the lot on which the building is located. The accompanying diagram illustrates how FAR works. It does this using an FAR of "1.0" and shows three simple ways that a 1.0 FAR might be reached: one story covering the entire lot, two stories covering half of the lot, or four stories covering a quarter of the lot-all result in the same FAR.
B. FAR Calculation Method. Within the Regional Commercial (RC) subarea FAR will be calculated using all interior space, regardless of use. This includes interior stairways, hallways, etc. Basement and attic spaces that are finished for habitation will also be included. Structured parking does not count towards FAR minimums or maximums.
Note: A different FAR calculation method applies within the residential zoning and apartment residential districts of the University District Zoning Overlay as described in C.C. sections 3325.805 and 3325.913, respectively.
