SEC. 16-31.  FRONT YARD.
   (A)   There shall be a front yard setback of not less than 20 feet; except that houses constructed with garages having a swing driveway, with the entrance facing the side property line, may have a minimum 15-foot setback.  Where standard dwellings within any block vary from the required setback, the average setback of such standard dwellings shall determine the required setback within that block if the standard dwellings comprise at least 60% of the block.
   (B)   In calculating the average setback, houses on reverse corner lots and houses wholly on the rear half of the lot shall not be counted.  In no case shall setbacks of less than 15 feet be allowed, or setbacks of more than 60 feet be required.
   (C)   There shall be a distance of not less than 20 feet, measured at the center line of the driveway, between the garage door and the front property line.
