Firefighters are investigating a condominium fire in Norcross that left 20 people homeless Tuesday, officials said.

About 60 Gwinnett County firefighters responded to a 4:30 p.m. report of a fire at the Olde Mill Crossing condominiums on Olde Mill Lane at Graves Road, Gwinnett fire spokesman Capt. Tommy Rutledge said.

No one was injured in the blaze, which Rutledge called the equivalent of a two-alarm fire.

"It certainly was a challenging fire," Rutledge said. "We had two multi-family buildings burning."

Buildings 800 and 900 — with two stories and eight units each — were burning when firefighters arrived.

"The roof was completely burned on building 900 and [at least] partially burned in building 800," Rutledge said.

He said many of the units had at least fire, smoke, heat or water damage.

"The fire originated outside building 900 in some landscaping underneath a stairwell," Rutledge said.

Wind and radiant heat likely spread the fire to the adjacent building 800, he said.

Firefighters had the blaze under control by 6:51 p.m., Rutledge said.

Officials from Red Cross of America were onsite to aid victims, he said.
