Investigators in Northwest Washington are trying to figure out what sparked a fire that began in one rowhouse and spread to another.
Fire and EMS units responded to an emergency call in the 1300 block of Oak Street NW around 1:30 a.m. Sunday. The flames were so heavy a second alarm crew was called to help put out the fire, which took about 90 firefighters to put under control approximately an hour and a half later.
A wall of the home collapsed during the fire, and heat from the blaze caused damage to nearby homes, WTOP reported.
One firefighter was also taken to a local hospital, where he was treated for non-life threatening injuries. Several residents from nearby homes were evacuated and three resident displaced due to the fire, heat and smoke, according to firefighters.
No one was living in the building, which suffered significant damage and is believed to have been under construction or renovation, officials said.
