Seven construction workers were hospitalized for smoke inhalation after a fire at the vacant Renoir Hotel on Monday, Fire Department Chief Joanne Hayes-White said.
The three-alarm blaze at 45 McAllister St. was reported at 12:03 p.m. and declared under control at 3:22 p.m.
Firefighters initially went into the eight-story structure to fight the fire, but exited after hearing explosions that possibly came from propane tanks inside the building, according to the department.
About two dozen construction workers were in the building when the fire started in between the first and second floors. All of the workers got out of the building, but seven were hospitalized for smoke inhalation. Their injuries were not considered life-threatening.
The 135-room flat-iron building at Market and McAllister streets is owned and managed by The Kor Group, a real estate company based in Los Angeles. It closed last year for renovations.
The Kor Group did not respond to requests for comment Monday.
Market Street was closed in both directions due to the fire, causing Muni lines to be rerouted.
The cause of the fire has not yet been determined.
