Firefighters responded to the blaze in the 600 block of Kimberley Place at about 2:15 p.m. after the fire was reported by a neighbor, said Martinez-Columbia Fire Rescue spokesman Jeremy Wallen.
No one was inside the two-story brick home in the Wellington subdivision when the fire started, Wallen said.
The homeowner’s identity was not immediately known.
Fire damage to the two-story brick home was contained to the upstairs bonus room, but smoke spread throughout the home, Wallen said.
The cause is currently undetermined, but considered accidental, he said.
