Brooklyn, NY – Flames tore through the top floor of a three-story mixed-occupancy building on Church Avenue late Friday night, triggering a three-alarm response that brought roughly 170 firefighters to the scene and left five people injured.
The fire broke out at 3322 Church Avenue, where arriving crews encountered heavy fire on the building’s top floor, according to the New York City Fire Department. The intensity of the blaze prompted commanders to escalate the response to a third alarm.
Deputy Chief Edward Esposito said units were met with significant fire conditions upon arrival, requiring additional resources to contain the flames. Approximately 40 FDNY units responded to battle the blaze.
It took firefighters about 90 minutes to bring the fire under control. Smoke and flames were visible from the upper levels as crews worked to prevent the fire from spreading to adjoining structures.
Four civilians and one firefighter sustained minor injuries during the incident and were transported to local hospitals for evaluation and treatment.

The scale of the response underscores the challenges posed by fires in mixed-occupancy buildings, where residential and commercial spaces share the same structure. Firefighters conducted searches of the building while hose lines were advanced to the upper floors.
The injured firefighter was treated for minor injuries sustained during suppression efforts, according to the FDNY.
Officials have not released the identities of the injured civilians. Their conditions were described as minor.
