1401.6.1.1 Height Formula
The following formulas shall be used in computing the building height value.
EBH = Existing building height in feet (mm).
EBS = Existing building height in stories.
CF = 1 if (AH) — (EBH) is positive.
CF = Construction-type factor shown in Table 1401.6.6(2) if (AH) — (EBH) is negative.
Note: Where mixed occupancies are separated and individually evaluated as indicated in Section 1401.6, the values AH, AS, EBH and EBS shall be based on the height of the occupancy being evaluated.
