A Brooklyn building collapse that killed eight people, including two children, has triggered a criminal investigation after city records revealed that contractors at the neighboring construction site violated a stop-work order and that an earlier inspection documented serious deficiencies in the building's exterior walls.
The three-story building at 1321 Flatbush Avenue collapsed into an excavation site at 2625 Bedford Avenue on November 11, 2026, injuring at least 18 others. The disaster has prompted inspections at more than 160 other construction sites associated with companies involved in the project.
Records from the New York City Department of Buildings show that inspectors ordered demolition stopped at the Bedford Avenue property on March 20 after finding inadequate overhead protection for neighboring buildings. When inspectors returned on April 23, they discovered that demolition had continued despite the order.
N Tech Design of America, the demolition contractor, received a $10,000 penalty for violating the restriction. The city lifted the stop-work order on May 8 after the violations were corrected. Records show the fine was paid in October.
Excavation for the new building's cellar began September 10, approximately two months before the collapse. Workers were excavating the property when the neighboring structure fell into the construction site.
A pre-construction survey conducted on March 5 had already documented cracks and other deficiencies along the exterior walls of 1321 Flatbush Avenue. The inspection rated the north facade in poor condition, indicating major deficiencies.
The survey was intended to establish the neighboring building's condition before construction began. Investigators are now examining whether excavation affected the foundation of a structure whose walls already showed signs of damage.
Following the collapse, the Department of Buildings issued a new full stop-work order at the Bedford Avenue property. An inspection notice cited unsafe construction operations at the neighboring site, although engineers are still determining the precise cause of the structural failure.
Brooklyn District Attorney Eric Gonzalez is investigating whether criminal conduct contributed to the deaths. Prosecutors are examining whether contractors, developers or other parties failed to take required precautions to protect surrounding properties during demolition and excavation.
New York City construction rules require contractors excavating near existing structures to provide appropriate support and protection against damage. Such precautions are particularly important when excavation extends below the foundations of neighboring buildings.
The city had approved excavation and foundation work for a three-story building at 2625 Bedford Avenue. A separate proposal called for a nine-story mixed-use development, but the larger project had not received approval.
Townhouse Builders Inc., the project's general contractor, previously faced lawsuits alleging damage to neighboring properties during separate construction projects in Manhattan and Brooklyn. The allegations involved structural damage during excavation and renovation work. The company denied the claims in the Manhattan case, which appears to have been resolved outside court.
Mayor Zohran Mamdani has ordered inspections of more than 160 construction sites linked to six entities involved in the demolition and excavation project. The city has also commissioned an independent engineering investigation into the collapse.
The disaster has drawn attention to staffing shortages at the Department of Buildings, which had 168 vacant positions out of 1,855 authorized jobs as of Friday. City Council Speaker Julie Menin has called for those vacancies to be filled as officials examine the city's enforcement of construction safety rules.
Buildings at 1323, 1325 and 1327 Flatbush Avenue remain subject to vacate orders as engineers assess their stability. The city has halted work at the excavation site while independent engineers investigate the structural failure and Brooklyn prosecutors examine whether criminal charges are warranted.
