Residents had self-evacuated the building mostly by the time units arrived. Firefighters initially moved in for an offensive attack, but later pulled out and assumed a defensive posture. 

Approximately 33 units were rendered uninhabitable as a result of varying degrees of fire, smoke and/or water damage. The damage displaced an unspecified number of residents, but the American Red Cross responded to assist with their needs.
