(OP)
ASCE/SEI 7-05 12.7.3 states that if you have structural irregularities Type 1a, 1b, 4 or 5 in Table 12.3-1, that a 3-D model is required with three dynamic degrees of freedom...
For residential construction, Type 4 irregularities are quite common, and Type 5 comes up occasionally also. Does this imply that I would have to do a 3-D dynamic analysis for a single family residence with these irregularities? Has anyone ran into this situation?

Is your structure a typical stick built house? Do you have masonry, steel bracing?
