Lt. Dan Dupree with Cobb Fire said 911 received a call about 2:54 p.m. from a resident that said there was a fire in a condo in the Willows by the River complex off Riverlook Parkway.
When they arrived on scene, the fire was through the roof of the three-story building, he said.
The fire affected 16 condo units that housed approximately 19 people. All but one of the residents are adults.
“The fire is still under investigation, and we have no idea how it started,” Dupree said.
Neighbors at the scene said they had heard the source of the fire may have been a grill that was left on at a second-floor unit.
Fire officials are looking into the possibility of a smoking grill but could not confirm that information, Dupree said.
The top floor and attic of at least one third-floor unit were heavily damaged, along with the second and first floors, from smoke and water damage.
Dupree said the roof of the building caved in.
During an initial search of the building, no one was found, but he couldn’t confirm anything until a second search had been completed.
Cobb Police were also called to the scene to keep people at a safe distance from the fire and to direct traffic.
“Access to other buildings is closed off for the next several hours,” Dupree said Monday afternoon.
He was unable to say how many firemen or trucks responded to the scene. He also couldn’t say how many residents were at home when the fire started and had to be evacuated.
Representatives from the American Red Cross showed up around 7 p.m. to assist residents, and multiple firefighters remained on the scene until late Monday.
“We will have guys there through the night to make sure there aren’t any more rekindles,” Dupree added.
