New York City is checking about 100 construction sites connected to firms involved in the project next to a building that collapsed in Flatbush, Brooklyn. Mayor Zohran Mamdani said Thursday that eight people died in the collapse, including two children and two construction workers. He said 18 people were injured, including four firefighters, and one person was in critical condition.

The three-story building at 1321 Flatbush Ave. fell into the open construction site next door at 2625 Bedford Ave. just after 4 p.m. Eastern on Wednesday, Nov. 11. The mayor asked people to avoid the area. Flatbush Avenue was closed between Clarendon Road and Bedford Avenue.

Firefighters pulled several survivors from the rubble Wednesday evening. Bonsignore said Thursday that rain would hinder the work and firefighters would stay until they were sure nobody was still trapped. The city set up a reception center for affected families at the Flatbush YMCA, 1401 Flatbush Ave. The FDNY finished searching the site Thursday afternoon.

The lot at 2625 Bedford Ave. is being prepared for a new building. Department of Buildings filings in the city's public job filing data show a January 2026 application for a nine-story mixed-use building with a cellar, filed for the owner, W6 Facility X LLC. Separate filings for the foundation and for support of excavation, the shoring that holds back soil and neighboring structures while a lot is dug out, have permits that were last updated Sept. 9. The main new-building application was still listed with open objections from the department.

The lot was cleared earlier this year. A city violation record shows that on April 23, a Buildings Department inspector cited the demolition contractor, N Tech Design of America, for continuing work while a stop-work order was in effect. The inspector compared photos with ones taken March 20, when a one-story building was still standing on the lot. The violation was Class 1, the most serious category, with a $10,000 penalty, and the record shows the contractor admitted it. It is listed as resolved.

The cause remains under investigation. Mamdani said the Department of Buildings and law enforcement were examining both the collapsed building and the adjacent construction site, with the Brooklyn district attorney's office taking part.
