The girl faces two counts of aggravated arson and six counts of attempted murder in the early Saturday morning fire in Clayton. She is to appear in Family Court Monday in Woodbury.
The Gloucester County Prosecutor's Office said six members of the family, including the girl, were injured in the fire. The office said the teen suffered burns to her feet. Another girl injured her hip when she jumped from the second floor.
A woman and another relative were taken to a hospital. The woman's husband and a 9-year-old child were treated for burns. Investigators believe the fire was set with gasoline.
