A large fire burned at a six-story residential building in San Francisco's Tenderloin District early Friday morning, leaving dozens displaced, officials said.

The fire started at around 3 a.m. at a building on Golden Gate Avenue near Taylor and Market streets, adjacent to the Golden Gate Theatre. The San Francisco Fire Department said the fire started on the top floor and reached three alarms, spreading to the attic and roof of the building. Over 100 firefighters at the scene were able to prevent it from spreading to lower floors and nearby buildings, the department said.

Multiple people were rescued and self-evacuated, and a total of 45 residents were displaced, but there were no injuries, the department said. Two cats were also rescued, one that was treated by medics at the scene and another cared for by Animal Control.

Evacuated residents were provided temporary shelter at the corner of Golden Gate and Jones Street aboard a Muni bus. The Red Cross and other city agencies were called in to assist the displaced residents, the department said.

The fire was contained by 5:30 a.m., and firefighters remained on the scene for several hours. The cause of the fire was not immediately known.
