Firefighters have "knocked down" a single-story guest house fire at 20 Ciervos Road in Los Trancos Woods, an unincorporated community in the hills south of and above Portola Valley, that had been burning since around 5:30 p.m. Thursday, Fire Chief Dan Ghiorso of the Woodside Fire Protection District said less than an hour after the fire was reported.
In a message issued at 6:53 p.m., the San Mateo County Office of Emergency Services described the fire as "under control."
The alarm came in at 5:49 p.m., according to firedispatch.com, and dispatchers deployed six fire engines in the initial response.
The first engine on the scene appeared to be in need of water, which became available a few minutes after it arrived.
Firefighters were advised to proceed with caution up Alpine Road and be on the lookout for people on foot and in vehicles who were leaving the area, according to an emergency services radio report.
Firefighters are now with the homeowner and attributed the fire to sparks escaping from an existing fire, according to the radio report.
