Officials say flames from a car fire grew and spread to a nearby home near Ninth Street and Jensen Avenue at around 3 am.
Pictures from the scene show several cars destroyed by flames and you can see there are some homes in the surrounding area.
Flames damaged nearby power lines and PG&E has since de-energized power in the area as crews extinguish the flames.
Fire crews worked to keep the damage to one home.
No injuries have been reported at this time.
