This from Eric Haak:
At approximately 0605 hrs on Sunday morning (2/12), the Englewood Fire Alarm Office received several calls for a fire at the intersection of 44th and Shields Ave. Engine 50 landed on the scene and confirmed a fire in a 2.5-story vacant frame with exposure to a 1.5-story occupied frame. Two minutes later, the 2nd Battalion reported he had heavy fire in the 2.5-story and requested a Box. The first image below was taken just before Engine 50 opened up with their deck gun which knocked down a lot of the visible fire in the front. There was a lot of fire extension into the occupied exposure and companies made an interior attack on that structure. Eventually Squad 5’s Snorkel and Tower Ladder 39 were brought down to mop up the remaining fire in the original building which was under rehab. In an October, 2015 Google Streets image, the building was a Red-X and appeared to have had a basement fire in it previously.
