Last month, family members discovered the body of 58-year-old Crosby Lipscomb on the floor of his bedroom.
The medical examiner said Lipscomb died from carbon monoxide poisoning and inhalation of smoke and soot from the fire.
Firefighters were disciplined following the incident.
And now under new procedures specific fire companies will be assigned to search specific parts of fire-affected buildings. Progress of the searches will be tracked in writing by command staff on the scene.
