SAN FRANCISCO (KRON) — A two-alarm fire at 400 Upper Terrace Drive in the Ashbury Heights neighborhood displaced 40-50 people, officials stated in a tweet.

Officials tweeted that the apartment building’s third floor was on fire.

Two people have been rescued and no injuries were reported, authorities say. Multiple people were evacuated from the building. Firefighters spent hours containing the fire, checking out hot spots, looking into the cause, and reuniting pets with their owners.

Firefighters are working with Red Cross to help those displaced by the fire.

The fire is currently contained. Residents are asked to avoid the area.

The building is yellow tagged (not to be populated) and will be reevaluated Tuesday. One firefighter suffered minor burns but will be OK, according to a tweet from the San Francisco Fire Department.
