The fire was classified as a "511" fire plus a special alarm for more fire trucks, the Fire Department said.
"This will be an extended operation. No injuries so far. 511 plus special is extremely rare," the department's media affairs office said on Twitter.
The rear part of the vacant building had collapsed, but there were no injuries as of 10 p.m., the TV station said.
