Flames broke out at about 10:00 p.m. in building E at the Spring Village Apartments, located on the 600 block of Polar Street in Sharon Hill.
Fire crews pulled one person from the building. Paramedics treated the person at the scene, and at this point there is no word on that person's exact condition.
The fire has left 12 people from four families homeless. Four other families are trying to determine if they will be able to return to their apartments.
The Red Cross of Southeastern Pennsylvania is helping those who are displaced with food, clothing and temporary shelter at a nearby motel.
