[NAME] Calculator | Unnamed: 1 | Unnamed: 2 | Unnamed: 3
Instructions:  Enter the information in the white boxes below.  The spreadsheet will calculate the proposed FAR (floor area ratio), the 100% max FAR (per the Zoning Ordinance), and the 85% [NAME] FAR (per the Zoning Ordinance).  Additionally it will determine whether a FAR Modification is required.  The Net Lot Area does not include any Public Road Easements or Public Road Right-of-Way areas.  The proposed TOTAL Net FAR Floor Area shall include the net floor area of all stories of all building, but may or may not include basement/cellar floor area.  For further clarification on these definitions please refer to SBMC §28.15.083.

1. NET LOT AREA excludes the public road easements and right-of-way
2. NET FLOOR AREA includes all floors of all buildings, garages, carports and accessory buildings, but not secondary dwelling units. Net Floor Area is the area within the surrounding exterior walls of a building exclusive of the area occupied by the surrounding walls, vent shafts and courts. Do not include crawl space or attics if interior floor to ceiling height is less than 5’ (This is the same for FAR and zoning.)
3. BASEMENT LESS THAN 5' FROM GRADE TO CEILING - If a basement or cellar is less than 5' from exterior grade to ceiling, it is NOT counted as floor area. (This is different for FAR and zoning. It will still count as floor area for zoning purposes i.e., parking, density, coastal, if interior floor to ceiling height is greater than 5’)
4. BASEMENT GREATER THAN 5' FROM GRADE TO CEILING - If a basement or cellar is greater than 5’ from exterior grade to ceiling, the net floor area for FAR purposes may be reduced by 50% if the vertical distance from exterior grade to ceiling is 4’ or less for at least one-half the circumference of the exterior walls of the basement or cellar.
