Firefighters were dispatched shortly after midnight to reports of flames on the roof of a two-story commercial building at 9160 Gramercy Road. When crews arrived, the building was fully engulfed in flames, according to the San Diego Fire-Rescue Department.
Firefighters initially entered the area but switched to a defensive attack from outside after determining the structure was unstable, officials said. Ladder trucks poured water onto the fire from the front and right side of the building as the blaze grew.
