Flatbush Building Collapse at 1321 Flatbush Avenue: What Injured Families and Workers Should Know About Their Legal Rights

What Happened in the Flatbush Building Collapse on November 11, 2026?

Shortly after 4 p.m. on November 11, a three-story building at 1321 Flatbush Avenue in Brooklyn collapsed into an active excavation at 2625 Bedford Avenue. At a November 12 briefing, Mayor Zohran Mamdani said eight people had died, including two children, and at least 18 people had been injured. The cause remains under investigation.

Workers were digging at the site when the building came down. The neighboring building at 1323 Flatbush Avenue lost part of an exterior wall, leaving apartments exposed, and the FDNY has warned that a secondary collapse is the main danger as recovery continues.

Many were taken to Kings County Hospital, and ABC7 New York reports that several of those killed appear to have been construction workers. Public schools were closed for Veterans Day.

What Caused the Flatbush Building Collapse?

The cause of the Flatbush collapse has not been officially determined, but the stop-work order the NYC Department of Buildings (DOB) issued at the construction site next door cites unsafe construction operations that caused the collapse, and DOB is still investigating.

• DOB tied its stop-work order to the construction next door. DOB Commissioner Ahmed Tigani said crews were "digging down" when the building fell. The stop-work order DOB issued Wednesday cites "unsafe construction operations causing adjacent building (1321 Flatbush Avenue) to collapse," as reported by Construction Dive.
• The construction lot had already been cited this year. DOB issued a stop-work order at 2625 Bedford Avenue in March, during demolition of a one-story building, because required safety measures such as netting and sidewalk sheds were missing. In April, an inspector found demolition had continued in violation of that order and issued another penalty, Gothamist reports.
• The excavation plans called for protecting the building next door. Engineering plans filed with DOB called for shoring to support neighboring buildings, vibration monitors, and crack gauges on surrounding buildings, under a special inspector's supervision. It is not yet known whether those steps were followed.
• The collapsed building was 96 years old. 1321 Flatbush Avenue was built in 1930, according to NY1. Records from the NYC Department of Housing Preservation and Development (HPD) list 98 open housing-code violations against the building.
• Plans for the lot grew. DOB approved a three-story building for the site. A newer plan for a nine-story building had not been approved, according to CBS New York.

NYC Building Stability and Excavation Complaints Topped All of 2025 Before the Collapse

Before the collapse, the NYC Department of Buildings (DOB) had already recorded 5,294 complaints in 2026 involving building movement, structural stability, excavation, or inadequate protection or support, more than in all of 2025, according to our review of DOB complaint data on NYC Open Data.

That’s about 17 complaints a day citywide. In Flatbush and East Flatbush, October was the busiest month of 2026 through November 10, with 18 complaints. Citywide, complaints that an excavation was undermining an adjacent building rose 53%, from 107 in all of 2025 to 164 in 2026 through November 10.

Who’s Responsible When a Building Collapses Into a Construction Site in New York?

In New York City, whoever causes an excavation generally must protect neighboring buildings at their own expense under NYC Building Code § 3309.4, so the construction site's owner, developer and contractors may be responsible when that protection fails. Whether the neighboring owner gave permission to access their property can affect how that duty applies.

The investigation into this collapse is ongoing. Nothing here is a conclusion about any party's responsibility.

Depending on what investigators find, parties who may be responsible could include:

• The owner and developer of the construction site at 2625 Bedford Avenue
• The general contractor and excavation, shoring or foundation subcontractors
• The owner or manager of 1321 Flatbush Avenue, if the building's own condition played a role
• More than one party at once, since New York law allows responsibility to be shared

Property owners must keep their buildings reasonably safe, which is the core of New York’s premises liability law. Workers' claims under the Scaffold Law (Labor Law § 240) and Labor Law § 241(6) depend on the work being done.

Families who have lost a loved one can bring wrongful death claims under N.Y. Estates, Powers and Trusts Law § 5-4.1, and a separate survival claim may cover a person's conscious pain and suffering before death.

What Evidence Matters After a Building Collapse?

After a building collapse in New York, the evidence that matters most is the construction site's permits, shoring and monitoring records, inspection history and video, and much of it can disappear once the site is cleared.

Records that may matter include:

• FDNY and NYPD incident reports
• DOB permits, inspection records, stop-work orders and violation history for both properties
• Excavation, shoring and underpinning plans, plus vibration and crack monitoring records for the neighboring building
• Site safety logs, special inspection reports, daily reports and photos from the construction site
• Surveillance and phone video from nearby buildings and stores
• Witness statements from residents, workers, neighbors and first responders
• Medical records from Kings County Hospital and other providers

Video is often overwritten within days. Our building collapse lawyers can send preservation letters to the owners, contractors and nearby businesses so this evidence is kept.

How Long Do You Have to File a Claim After a Building Collapse in New York?

In New York, injury claims from the Flatbush collapse generally must be filed within three years, wrongful death claims within two years of the death, and any claim against New York City needs a Notice of Claim within 90 days.

Our New York building collapse lawyers review each situation individually, and confirm which deadlines apply.

What Should You Do in the First Days After the Flatbush Collapse?

In the first days after the Flatbush collapse, get medical care, keep every record, and get legal advice before you give a statement or sign anything.

1. Get medical care, even for injuries that seem minor. Crush injuries, head injuries and dust exposure can get worse over time.
2. Get help with housing and supplies. New York City Emergency Management and the Red Cross opened a reception center at the Flatbush YMCA, 1401 Flatbush Avenue.
3. Keep every record: hospital paperwork, your lease, messages with your landlord or employer, Red Cross paperwork and receipts.
4. Save photos and videos you or neighbors took before or after the collapse, including any of the construction next door.
5. Write down what you saw and heard, such as cracking, shaking or work at the site in the days and weeks before.
6. Don't give recorded statements or sign anything from an insurance company, developer or contractor before you get legal advice.
7. Talk to a lawyer early so evidence can be preserved. The consultation is free.
