ORINDA (CBS SF) — Crews put out a fire that burned an outbuilding and some vegetation in Orinda on Monday and threatened to spread to a nearby home, Moraga-Orinda fire district officials said Tuesday.

Neighbors on Muth Drive called the fire district around 1:20 p.m.  to report a blaze that was burning an outbuilding and deck and had spread to adjacent brush, Interim Fire Chief Stephen Healy said.

Crews were able to bring the fire under control in less than 15 minutes and no homes were damaged, Healy said.

The cause of the fire was under investigation.

Healy said staffing had been beefed up because of the red flag warning currently in effect, allowing crews to respond more quickly and aggressively to the fire.

Fire officials were reminding residents not to mow any vegetation while the fire warning was in effect, and that any open flame can spark a large fire.
