Too soon to tell. They need undisputable facts about the building shifting positions, and exactly what the risk is. High risk means the governing authority can condemn it, get people out, and sort out liability later.

No doubt determining liability will involve a lot of insurance negotiations along with various court cases. Maybe there's a code violation, but plans showing an inevitable violation were approved? Who is liable for that? Etc. There are many possible sources, even distributed sources, for a mistake like this. But central is determining the scope of the damage.
