| The table below summarizes the floor elevations by room. The elevation differences (column 4) were obtained from CAD Drawings 1 in Appendix A. The NAHB Performance Standard for floor elevation difference is 0.50" in 20 feet or .025" per foot (see NAHB Performance Standards in Appendix D). The allowable elevation difference (column 5) was obtained by multiplying the room dimension with the asterisk by 0.25. The defect factor is column 4 divided by column 5. The defect factor is a measure of the severity of the slope or sag in the room. The factor should not be over 1.00 to meet the NAHB standard. |
