It happened just before 2 Saturday morning on Lynn Road near North Avenue and the North-South Tollway.
The fire burned through the roof and 12 units on the north side of the building.
"Everybody was like trying to help, everybody get out of the building and when we arrived on the side of the building there was already a lot of people standing on the side. So it looks like everybody got out safe and on time," said building resident Natasha Love.
No one was injured in the fire.
