This has probably been discussed before but am unsure how to find it. I am analyzing a 3 story building as a non-separated...ground floor B occupancy, with 2 floors directly above as R-3 occupancy. Per CBC section 508.3, the allowable height (and area) of the building or portion thereof, is based on the most restrictive occupancy (in this case B). Table 504.4 allows 2 stories for B occupancy type VB (non sprinklered). If the building is 3 stories (which exceeds the B maximum of 2 stories), but the B portion of the building is only 1 story, would this be allowed? Is this what they mean by the portion thereof? Thank you.
