The roof atop a group of rowhouses collapsed after catching fire in Braddock on Thursday morning.
The fire broke out shortly after 1:30 a.m. on the 200 block of Oliver Street.
Firefighters were on the scene for several hours.
No one was inside the home and there were no reports of injuries.
Braddock VFD Chief C.J. Kaminsky said the fire did spread to another abandoned home behind the row houses. Those homes will have to be torn down.
There was no initial word on the cause of the fire.
