Question 1

Floor Area Ratio (FAR)

Answer 1

FAR = the total building square footage (building area) divided by the site size square footage (site area).

Example 1: Consider a big box retail store with a large parking lot. The actual building
may take up only 1/4 of the project site and the other 3/4 is paved for parking spaces.
The FAR would be 0.25.

Question 2

Building Density

Answer 2

Bldg floor area/ site area (sq ft / acre)
