Two ends units were engulfed in flames, Butz told NBC 7.
Crews arrived to find smoke and flames coming from the building.
Kathy Smith said she saw the flames and drove over to see what was going on.
"I was just hoping there was nobody in there. There was a real loud bang and the flames got really big and it was pretty scary," Smith said.
She told NBC 7, a friend of hers lives in the unit below where the fire began but was able to get out.
Butz said 32 people live in the complex, 20 of who were displaced. Other residents may also be displaced, depending on the extent of the fire damage.
