No one was killed in Thursday's blaze on Hillcrest Avenue, which left the 10 people who lived there homeless. But two of them were treated for smoke inhalation.
Nineteen-year-old Shanta Dargbeh of Bristol Township was arrested the next day and now faces 10 felony charges, including aggravated arson.
Authorities say Dargbeh became angry after hearing that her ex-boyfriend had taken another girl to the Trenton High School prom last weekend.
Dargbeh is being held on $250,000 bail.
