The fire broke out Friday afternoon in the 5500 block of Edgebrook Forest Drive.
According to the Harris County Fire Marshal's Office, the home belonged to a hoarder, filled with debris and making it difficult to battle the fire and perform an investigation.
"Hoarding causes a whole lot of problems not only for firefighters but the residents," an investigator said. "If a fire starts inside a residence where there is a hoarder, it makes it extremely difficult for them to get out."
After several hours of searching, authorities located a body. The victim's identity has not been released.
Neighbors told ABC13 the fire may have started when a guest at the home started a fire outside to stay warm. Officials have not confirmed the cause of the fire.
