It took some doing, but I think I finally have convinced the main architect we work with to quit giving us houses that are XX'- 4" (or 8") wide. They have agreed to go with 0", 3" 6", or 9" because 10 lots 45.33' wide adds up to 453.30' but the overall dimension will always come up 453.33'. Yes, it can be fudged, but everyone's life is easier if you eliminate the potential problem.
