Los Angeles Fire Department firefighters were called out just before 7:30 p.m. Thursday. Crews were seen surrounding the building near E. 57th St.
The fire department said there was a partial roof collapse inside where debris initially stopped firefighters from fully extinguishing all hot spots within the rubble.
They put out the fire shortly after.
No injuries were reported and it's unclear what sparked the car fire.
The incident remains under investigation.
