What is the maximum number of stories for wood-frame construction?
Five-story wood buildings are increasingly common, but some designers used to other materials still aren’t aware that the International Building Code (IBC) allows five stories of wood-frame construction for most occupancies—including multi-family, military, senior, student and affordable housing—and six for business.
