Not legally.
In the state of NY, a 16 year old cannot legally move out of their parents house without their consent. They would have to go to court to become an emancipated minor to do so.

If a 16 year old gets kicked out of his parents house, they can inform the police. Parents are not allowed to legally kick a minor out of the home.
No.
