A two-alarm fire early Thursday in San Francisco's Mission District sent two people to the hospital and displaced a total of 22 people, according to fire officials.
Crews responded to a 12:18 a.m. report of the fire at 3036 16th St., where a debris fire that started outside the building wound up damaging 13 units and rendering the building uninhabitable, officials said.
Two people were taken to a local hospital with smoke inhalation injuries, and 20 more were displaced in the incident. Firefighters rescued two people using walkers, SFFD said.
The blaze also damaged the popular Taqueria Los Coyotes restaurant on the building's ground floor, and the building was red-tagged, fire officials said.
Firefighters had the fire under control by 1:46 a.m. and began an investigation, according to a 3:16 a.m. tweet from the San Francisco Fire Department.
Fire officials said later Thursday morning it was too early to tell if it was arson or how the debris pile ignited.
Red Cross and city services were at the scene, assisting the displaced residents.
