section 506.4 allowed the total allowable building area to increase depending on the number of stories. this logic was consistent with the 1997 ubc, section 504.2.
but in the 2009 ibc, this is only allowed for "single occupancy buildings". huh? i haven't seen a single occupancy building (other than residential) in years. what happened? so potentially any building we did under the 2006 ibc may be three times larger than what is allowed in the 2009 ibc? or did i miss something?
thanks for any help.
