Shaun Aspey, watch manager at Wigan fire station, said: "Once we got there we found somebody had been in, maybe sleeping rough. They had lit a fire on the third floor.
"Unfortunately it had been going for quite a while before it was discovered so had tracked along the floor. We had to rip up a lot of the floor and there was a lot of smoke."
The third floor of the building is vacant, but people had to be evacuated from the occupied ground floor while the fire burned.
Crews used a hose reel and thermal imaging camera to tackle the blaze and were there for around 90 minutes.
