On the afternoon of November 11, 2026, the three-story building at 1321 Flatbush Avenue in Flatbush, Brooklyn, collapsed into a construction pit next door. As of Thursday, November 12, officials say at least eight people have died and more than a dozen were injured.
Many readers now want to know who owns the property. This article sticks to public records and published news reports, and it will change as the investigation moves forward. Our thoughts are with the families and everyone affected.
Who Owns 1321 Flatbush Avenue?
According to property records reported by The Real Deal, the building is owned by Isolag Realty Corp. A deed signed in 2024 moved the property into that company. 6sqft reported that Olufemi Falade signed the deed and described the company as his corporate entity.
Older listings point elsewhere. Tenant-data sites such as Augrented still list Femi Realty Corp. as the owner, which may reflect an earlier registration. The more recent property record naming Isolag is the one news outlets are relying on.
Ownership and Key Stakeholders Table
| Party | Role | Status | Key Detail |
|---|---|---|---|
| Isolag Realty Corp. | Owner of record, 1321 Flatbush Ave | Current owner per property records | Received the property through a 2024 deed |
| Olufemi Falade | Signed the 2024 deed | Reported as the person behind the transfer | The Real Deal and 6sqft describe Isolag as his corporate entity |
| Femi Realty Corp. | Earlier listed owner or manager | Appears on older listings | Likely an earlier registration |
| W6 Facility X LLC | Owner of the lot at 2625 Bedford Ave | Filed a nine-story mixed-use project in January | Reported from Buildings Department filings |

What Records Show About the Building
The building dates to 1930 and was renovated in 1960, according to UPI. It stood at the corner of Flatbush and Bedford Avenues. The collapse also tore away the side of the neighboring building at 1323 Flatbush Avenue.
6sqft reported 61 open HPD violations at the time of the collapse, and Gothamist reported that city inspectors had documented hazards there before the disaster. Violations show a building’s condition, but they do not by themselves explain why it fell.
Who Owns the Construction Site Next Door?
The building fell into an excavation at 2625 Bedford Avenue. SNJ Today, reviewing city open data, reported that a nine-story mixed-use building was filed for that lot in January by W6 Facility X LLC. Gothamist reported that the lot is owned by a limited liability company tied to its developers.
The Department of Buildings said the developers held an active permit for excavation and foundation work, according to the local ABC station, ABC7 New York. Gothamist also reported that the developer had a record of flouting orders from a city agency. Whether any of this played a role in the collapse is for investigators to determine.
What Happened on November 11
The collapse happened shortly after 4 p.m., and more than 250 fire and EMS personnel responded, 6sqft reported. Mayor Zohran Mamdani said Thursday morning that eight people were dead and at least 17 injured, including three firefighters.
The Department of Buildings is investigating alongside law enforcement, according to CNN’s live coverage. Other reports put the injured at 19, note that officials have not established the cause, and say a reception center opened at the Flatbush YMCA for affected residents.
About the Address
Flatbush Avenue runs about 9.9 miles through Brooklyn, and the roadway itself is owned by the City of New York, according to Wikipedia. The Flatbush neighborhood is home to a large Black and Caribbean community, which is part of why this collapse has drawn so much attention to housing safety.
Owner of Record Is Not the Same as Responsibility
Being named on a deed or in property records tells you who holds title. It does not tell you who managed the building, who did the nearby construction, or who is responsible for what happened. Those questions belong to the Department of Buildings and law enforcement.
In New York, the title owner, a leaseholder, a manager, and a developer can all be different parties. That split also explains the layered ownership of the Twin Towers site.
How to Check Who Owns a New York City Building
Three public tools cover most questions. ACRIS shows deeds and mortgages, HPD shows landlord registrations and housing violations, and the Department of Buildings shows permits and building violations.
Records can lag behind real events, and registrations can expire. It is worth cross-checking at least two of them before drawing conclusions.
