Fire crews responded to a house on Vassar near Walnut around 3 a.m.
Several engines spent the morning hours working to put out the flames.
Visalia fire crews haven't specified how much damage was done to the home or how many people lived in the house.
Several neighbors said they believe the home was unoccupied because it was up for sale.
