Three people have been taken to the hospital after flames broke out at the Pebblecreek Apartments in Springfield late Sunday night.
Firefighters were called to the scene on south Fort between Sunset and Battlefield around 10:30pm Sunday.
When crews arrived, they found a large fire on the south side of the 1200 building.
The fire is believed to have started on the first floor and worked its way up to the attic.
Firefighters pulled two people from the building.
The flames damaged around 30 units, and the Red Cross has been called in to help find housing for those who have been displaced.
