Ah, but if the building is big enough (huge S-2) then the Business portion could be possibly less than 10 percent of the overall and considered an accessory occupancy - even better!Big Mac said:depending on the size of the building non-separated use might not be an option. The premise behind the code is that when separations are required the less hazardous occupancy needs to be separated and protected from the more hazardous occupancy. Based on separation requirements found in Table 508.3.3, one has to assume that the code considers the 'Use Group B' occupancies and the 'Use Group S-1' occupancies to be on an equal footing with regard to hazard. Conversely the code considers the 'Use Group S-2' occupancy to be less hazardous than the 'Use Group B' and therefore needs a fire resistive protection for the S-1.
