You cannot move out of your parents' home without their permission until you are 18 years old. If you move without their consent, they can have the cops pick you up as a runaway. Anyway who gives you a place to stay knowing you are a runaway can be charged with harboring a runaway. Why don't you just talk it over with your parents. You are essentially an adult and have demonstrated great responsibility.
Although I have answered the question to try to help you, you should consult with a lawyer in your area in person on the matter. In addition, my answer does not establish an attorney-client relationship between us.
18. Unless you can prove to a court you should be granted emancipation (freedom) earlier by proving you hold a job and can pay all bills including rent, food, gas, etc.
If the cops are involved, you are going to have to follow your parents' direction, and depending on the actions taken by the people you are living with, they could also get in trouble.
