Residential Floor Area Ratio (Far) Worksheet

For more FAR information click here (Word .doc).
For non-automated FAR worksheet click here (Excel .xls).

Update: 10/9/02 Error corrected for lots 15,000 to 30,000 square feet (was computing a gross residential floor area 1.9% too high).

Notes:  This online worksheet will do all FAR calculations automatically, please enter all the required measurements and information.  All measurements are in feet or square feet.  All measurements must be represented in decimal form.  For example, 2 feet and 6 inches should be represented as "2.5".  Users may only enter information into the user input column, all other fields will be automatically calculated.  Users may only type numbers and decimal points into input fields.  For example, "12,000" would not be accepted because it has a comma in it.  The calculations column should be ignored by the user.  A message of "N/A for this property" means that this field is irrelevant to the calculation of FAR.  Fields with the value "N/A for this property" should be ignored by the user.  No fields in the user input column should be left blank.  After all user input fields have been completed, the worksheet should be printed and signed.
