Firefighters were called to the 100 block of Scarlett Road at about 4:15 a.m. Saturday.
They arrived to find flames coming from a home.
It took them about an hour to bring the blaze under control.
Afterward, they discovered the body of a 55-year-old man inside.
The victim's name is being withheld.
New Garden Township Police say the home was believed to be unoccupied since another fire damaged the property about a year ago.
An investigation into the circumstances surrounding this most recent fire continues.
