Replace Chapter 14 of the IEBC with the following:
(Equation 14-1)
Note: Where mixed occupancies are separated and individually evaluated as indicated in Section 1404.3.1, the values AH, AS, EBH, and EBS shall be based on the height of the occupancy being evaluated.
(Equation 14-2)
AH = Allowable height in feet (mm) from Section 504 of the VCC.
EBH = Existing building height in feet (mm).
AS = Allowable height in stories from Section 504 of the VCC.
EBS = Existing building height in stories.CF = 1 if (AH) - (EBH) is positive.
CF = Construction-type factor shown in Table 1403.6(2) if (AH) - (EBH) is negative.
EDITOR'S NOTE: Equation 14-3 is amended in the following manner:
(Equation 14-3)
where:
Aa = Allowable building area per story (square feet).
At = Tabular allowable area factor (NS, S1, S13R, or SM value, as applicable) in accordance with Table 506.2 of the VCC.
NS = Tabular allowable area factor in accordance with Table 506.2 of the VCC for a nonsprinklered building (regardless of whether the building is sprinklered).
If = Area factor increase due to frontage as calculated in accordance with Section 506.3 of the VCC.
EDITOR'S NOTE: Equation 14-4 is amended in the following manner:
(Equation 14-4)
where:
i = Value for an individual separated occupancy on a floor.
n = Number of separated occupancies on a floor.
EDITOR'S NOTE: Table 1403.3, Compartmentation Values, has not been amended since being published in the proposed regulation in 39:14 VA.R. 1856-2028 February 27, 2023; therefore Table 1403.3 is not set out.

Table1403.6 (1) contains the appropriate protection values. Multiply that value by the construction-type factor found in 1403.6(2). Enter the vertical opening value and its sign (positive or negative) in Table 1404.1 under Safety Parameter 1403.6, Vertical Openings, for fire safety, means of egress, and general safety. If the structure is a one-story building or if all the unenclosed vertical openings within the building conform to the requirements of Section 713 of the VCC, enter a value of two. The maximum positive value for this requirement shall be two.
