Firefighters responded to a report of a structure fire at a two-story home at 704 Claridge Drive at about 5:10 p.m.
Arriving units reported seeing smoke and flames coming from the roof and sides of the house, fire officials said.
Crews located the fire at the rear of the home, and the blaze was extinguished.
No one was injured, and firefighters remained at the scene for about two hours.
Eight adults and one child were displaced, and the American Red Cross Bay Area Chapter was helping those residents find temporary housing.
The cause of the fire remains under investigation.
