It happened at a home in the 400 block of Second Street around 6:30 a.m. Sunday.
Firefighters from multiple departments responded to the blaze. The fire is believed to have started in the garage. A neighbor out for a jog saw the smoke and started to bang on the windows alerting the elderly couple inside. They escaped without any injuries.
Richland Township Fire Chief said there was a problem with getting enough water power from a nearby hydrant.
"We did have water issues down here the hydrants," said Chief Todd Shaffer. "We could not supply the water fast enough for that major of a fire so we had to call in additional crews to get water from old Farm Lane."
The fire marshal from the state was called in to investigate.
