What are American houses typically made of?

Depends on where people live. Where I live there are hurricanes, most houses are made of cinderblocks. When I lived in NYC most houses were made of bricks. Even if they were detached, like in one of the outer boroughs. Some houses are made of concrete and covered with stucco. Really depends on where.

depends where it is. houses in hurricane zones have full concrete walls. most others are wood frame. I think california has strict building codes too for earthquakes

Gingerbread and jelly beans.
