I'm 16 ganna be 17 in a few months I go to school and get good grades and have a job. I live in WI. And I live with my grandma. What do I need to do to get out of this house?

Who has legal custody of you, you can go live with them if that is not grandma. Beyond that you wait till you are 18,
Is there some reason you need to move, are you not safe in this home

Does she have legal custody of you? If not then you can live with the person that does. Otherwise as just stated you have to wait until you are 18 then you can move where ever you want to.
