Lot coverage is the amount of area your property covers on a zoning lot when viewed from above. Allowable lot coverage varies based on your zoning designation. For example, if your lot is 2,000 SQFT and your allowed lot coverage is 60%, you’d be able to cover your lot with 1,200 SQFT of building. 

FAR is a multiplier used to determine the total allowable floor area for your lot. The basic calculation takes the size of your lot and multiplies it by the FAR, which is listed in your zoning code. Let’s say you have a townhome that’s currently 3,500 SQFT, but based on the FAR, 4,000 SQFT is allowable. This means you’d be able to create a 500 SQFT extension in most circumstances.
