Until you turn 18, you are not considered an adult, and your parent has the legal right to determine where you live. The only exception is if you went to court to have yourself declared an emancipated minor, but you would have to show that you are supporting yourself.
If you do not obey your mother, she can file a juvenile petition to have you judicially determined to be "undisciplined." Once you are 18, you are an adult and do what you wish.
