I'm of two minds about it...

On the one hand, people should know better than to buy a house on a mud
pile, near a flooding river, at the top of a steep hill they can't drive
up in the winter, in a hole that will flood and/or they can't get out of
in the winter; but people do all those things.

On the other hand, what is the point of having building codes if the city
will allow developers to build on poor soil?
