The home was threatened by a fast-moving brush fire that broke out early Tuesday afternoon on San Bruno Mountain in Brisbane.
Air tankers, helicopters and 19 fire engines helped keep the flames from reaching a house at the high end of Bayshore Road, very visible from 101.
The three-alarm fire topped out at about seven acres and no evacuations were ordered.
The fire is expected to be completely under control by 7:00 p.m. Tuesday.
