The fire was reported around 9 p.m. in a three-story home at 8910 Burr St., according to fire Battalion Chief Eleanor Bolin-Chew.
One woman was rescued from the home by firefighters and transported to Highland Hospital, Bolin-Chew said.
While initial reports overnight from a fire dispatcher indicated the woman had died, the Alameda County coroner's bureau said this morning that no deaths have been reported in connection to the fire.
Bolin-Chew said she had no information on the woman's condition after she was transported to Highland Hospital.
The fire, which was under control by 9:29 p.m., is thought to have been accidental in nature, Bolin-Chew said. A final report on its cause is expected to be ready by early next week.
