At 2302 hours, Stations 51 and 53 were dispatched to the area of South Darlington Street and Holly Alley for the dwelling fire. Prior to arrival, Chief 53 was advised of multiple reports from neighbors and the West Chester Police Department of a working fire. Chief 53 called for the working fire dispatch, adding Station 52, as well as 56 for the RIT and Medic 91. The incident location was then updated to the 100 block of West Union Street. Upon arrival, 52 crews reported to manpower and stretched a 1-3/4" handline through the front door, to extinguish the fire in the rear of the dwelling and on the rear exterior wall, while the crew from Engine 51-1 knocked the bulk of the fire on the second floor. The fire was quickly placed under control. Crews performed overhaul and salvage operations before returning to quarters.
