About 25 people evacuated from an apartment building during a two-alarm fire early Tuesday were expected to be back in their homes by today.

Salt Lake City firefighters were called at 12:18 a.m. to a three-story building near 300 East and 200 South. The first arriving units saw smoke billowing from the attic.

A second alarm was called because of the building's size and the evacuations, Salt Lake City Fire spokesman Dennis McKone said.

The evacuated residents — wearing bathrobes and wrapped in blankets — watched the fire from across the street.

"We just grabbed a jacket," said Kristen Lemon, who lives in a basement apartment.

Firefighters battled the blaze inside the building and on its roof. The fire was under control in about 20 minutes, McKone said.

Damage was estimated at $100,000. The cause was still under investigation Tuesday afternoon.

The Red Cross provided shelter for the displaced residents Tuesday.
