The buildings were reportedly built by villagers in the 1970s and were in a poor condition.
Most victims were migrant workers who had been renting cheap rooms.
"They lost their lives to take advantage of cheap rent. It is horrible," Guo Lin, a witness told news outlet China News Service.
Six people have been pulled out of the rubble alive.
One survivor was a young girl who was protected by the bodies of her dead parents, reported the Global Times.
