Older couple now homeless after being rescued from flood (KING 5 Seattle channel)

Do they have to raise it to legally live in it? When I was a child, our home got flooded a few times, we just cleaned it up.... I mean it was a lot of work.... and then lived in it... There must be hundreds in the same position as them..... lets get them some help! https://www.youtube.com/watch?v=-MdLV2yzG-c
