seismic chapter 12 horizontal and vertical irregularities
if i am interpreting the code correctly, chapter12 - asce-7 '05, if my building is in category b for the table 12.3:
12.3-1
i need only consider numbers 1a, 1b, 4 and 5, and i may neglect numbers 2 and 3. and if i happen to have any of these irregularites, i must only abide by the sections noted next to category b on the right side of the table.
12.3-2
i need only consider numbers 4 and 5b and may neglect the rest. if i happen to have any of these irregularites, i also only need to abide by the sections listed by category b.
is this an accurate interpretation? all help is welcomed.  
check out our whitepaper library.
for what it is worth i also have a category b design and i interpreted the code exactly as you state above.
