2-alarm fire burns in San Francisco Presidio Heights neighborhood

San Francisco crews knocked down a two-alarm fire in the city's Presidio Heights neighborhood early Friday morning, fire officials said.

A three-story building in the area of Lyon and Clay Streets went up in flames around 4:45 a.m., and the blaze was raised to a second alarm response due to heavy fire from all floors of the structure, the San Francisco Fire Department said on social media.

The vacant six-unit residential building was under renovation. No injuries were reported. Residents in the area were earlier advised to shelter in place.

Crews were continuing to extinguish flames in void spaces to confirm all of the fire was out, while smoke has decreased, fire officials said.
