It is currently unknown what ignited the fire.

Battalion Chief Benny Fulkerson told KFOR that the structure had electricity going, but no gas.

Firefighters used ladder trucks to battle the five-story-high blaze.

Crews used ladder trucks to climb high and battle large flames burning on the building’s rooftop.

Rubber on the roof that Fulkerson described as a material that doesn’t respond well to water when there’s a fire exacerbated the situation, the battalion chief said.

The 80-90 firefighters at the scene will likely be battling the blaze into the night, and one floor might be lost, Fulkerson said.

KFOR crew witnessed large pieces falling from the top of the building, including a balcony.

The blaze grew larger into the night and was classified a five-alarm fire.

The 326-room luxury apartment complex was scheduled to open sometime in the spring with rooms starting at 600 square feet, ranging from $1,100 to more than $4,000 a month.
