Crews knocked down a two-alarm fire Friday morning at a vacant building in San Francisco, but the structure suffered significant damage, according to the fire department.
The fire ignited just before 4:30 a.m. and was burning on four floors of a residential bulding at Lyon and Clay streets in the city's Presidio Heights neighborhood, fire officials said. By 6 a.m., firefighters knocked down the blaze and were monitoring for hot spots.
No injuries were reported, and the owner of the building told fire officials it was vacant and undergoing a paint job.
Residents in the area initially were advised to shelter in place if there was heavy smoke in their area. No evacuations were issued.
About 60 firefighters responded to the scene, and as of 6 a.m., they had contained the blaze to the one building, fire officials said. When they first arrived, crews were challenged by the weather, heavy smoke and poor visibility, Capt. Justin Schorr told NBC Bay Area.
The cause of the fire was unknown and under investigation.
