Stranger in the garage

When I got back from Vacation I found someone living in my garage. He was sleeping in my minivan. He also had driven the van to the gas station to get gas for my lawnmower. ( I should be thankful he cut the grass right?) But he got in a little fender bender and now my insurance company has added him to my policy. My rates have doubled. I wanted to tell him to move out and go find his own place to live but he doesn't speak english and besides when my ancestors came to America 300 years ago they built a city on land that didn't belong to them.
I wonder if I should add an addition to the house so he doesn't have to sleep in the garage. I guess I can't afford to go on any more cruise ships for a while.
