In a lot of ways much the same:

When you get into the hills it gets different since you have areas of very stable limestone with pockets of unstable clay. That presents some foundation engineering issues.
The problem is that a lot of volume builders will throw a slab foundation down that is only supported with grade beams. It usually takes piers to have a stable slab. Piers are expensive.
