The death toll from the Brooklyn building collapse has risen to eight, New York City Mayor Zohran Mamdani announced on Thursday, as rescue teams kept digging through the rubble. The building at 1321 Flatbush Avenue collapsed into an adjacent construction site at about 4 p.m. on Wednesday, November 11, 2026. At least 17 other people were injured, including three firefighters.

Key Points

• Eight people have been confirmed dead after the three-storey building at 1321 Flatbush Avenue collapsed on Wednesday afternoon.
• At least 17 people were injured, including three firefighters. Four are in critical condition, five have serious but non-life-threatening injuries, and 10 have minor injuries.
• At least seven children are among the victims, officials said, though details have not been disclosed.
• More than 250 firefighters and emergency medical workers responded within a minute, and rescue teams worked overnight in extremely dangerous conditions.
• The cause is under investigation by the Department of Buildings and law enforcement, and rain through Friday morning is complicating the search.

What Happened

The collapse happened at about 4 p.m. on Wednesday, when the three-storey mixed-use building at 1321 Flatbush Avenue gave way and fell into the open excavation pit at the construction site next door. The building came down completely, leaving a mound of brick, concrete and twisted metal where the apartments had stood,

Firefighters and paramedics reached the scene within a minute. More than 250 firefighters and emergency medical workers were sent to the site, with search dogs and drones brought in to pick through the debris. Rescue teams pulled survivors from the rubble on Wednesday afternoon, including a woman who is six weeks pregnant, a mother with her two young children, and a man freed at about 4:45 p.m. By Wednesday night two people were confirmed dead. On Thursday morning, the FDNY confirmed to USA TODAY at 6:30 a.m. that five patients were dead on arrival, and about an hour later Mayor Mamdani announced the toll had risen to eight.

Background: The Building and the Site Next Door

The collapsed structure was a four-unit apartment building dating to 1930, a nearly century-old brick building. It stood beside a construction site where excavation work was under way for a planned nine-storey, 64-unit building. Permits issued on September 9 allowed excavation to a depth of 14 feet.

That neighbouring site, at 2621 Bedford Avenue, had already drawn the attention of city inspectors. According to earlier reporting, it carries a Class 1 violation from the city's Office of Administrative Trials and Hearings for allegedly working during a full stop-work order. Whether the excavation played a role in the collapse is now a central question for investigators, and officials have not yet said what caused the building to fail.

Brooklyn Building Collapse Death Toll: What We Know

The confirmed toll now stands at eight dead and at least 17 injured, a sharp rise from the two deaths reported on Wednesday night. The victims include at least seven children, and three of the injured are firefighters hurt during the rescue. Officials have not released the names or ages of the dead,

Of the 17 injured, four are in critical condition, five have serious but non-life-threatening injuries, and 10 have minor injuries. The figures were still changing on Thursday. The most urgent unknown is how many people may still be trapped. FDNY Chief John Esposito said authorities do not know how many people might still be missing, and the rescue operation could take several days, with crews removing debris by hand where heavy machinery could endanger anyone still alive beneath it.

Reactions and Quotes

Chief Esposito described the scene as one of the most difficult his crews have faced, saying rescue teams were working under "extremely dangerous conditions" as they searched a pile of rubble that could shift without warning. He said the operation could take "several days", a sign of how much debris must be cleared before officials can say no one else is trapped.

Mayor Mamdani announced the rise in the death toll on social media on Thursday morning, about an hour after the FDNY confirmed five people dead on arrival. Neighbours said they felt the ground shake and ran into the street to find the building gone.

Why It Matters

The collapse matters far beyond one Brooklyn block because it raises direct questions about how the city protects older buildings when deep excavation begins next door. New York has rules that require developers to protect neighbouring structures during construction, and stop-work orders are meant to halt dangerous work. If the excavation beside 1321 Flatbush Avenue was under a stop-work order and work continued anyway, the investigation will need to establish who knew what and when.

It also matters because of the scale of the loss. Eight people dead, seven children among the victims, and a rescue that may take days: the human cost is already among the worst from a building collapse in New York in years.

What Happens Next

The rescue operation will continue for as long as it takes to clear the site, and officials have said it could take several days. Search dogs and listening equipment will be used to check for signs of life and the work will go on around the clock in shifts. Rain is near 100 percent likely through Friday morning, with temperatures dropping to the upper 30s. The investigation will run alongside the rescue, with the Department of Buildings and law enforcement examining the collapsed building, the excavation next door, the permits and the inspection history.
