NYC owner networks

The deed record links 346 companies into 27 networks, covering 463 buildings and $1.61B in stated prices on the priced deeds.

New York property is held one building at a time, each in its own limited liability company. That is ordinary practice, and the side effect is that a single operation appears in the public record as dozens of unrelated strangers. These are the 27 groups the deed record links back together.

11 networks moved as a block: five or more buildings changing hands on one date, which is one transaction wearing many names. The largest is FLGSP, 82 buildings on March 31, 2026.

Every network

Ranked by the largest number of buildings taken on a single day, then by portfolio size. Each links to its companies, its buildings, and what those buildings carry. Deeds recorded through September 29, 2026, the most recent day the city has published.

How the record links these companies

Grouping needs two independent things in the record to agree: a shared naming pattern across numbered siblings, and a shared mailing address on the deed filings, corroborated by a distinctive token that at least half the companies at that address carry. A third pass adopts a company whose coined name belongs to a group and which files from a ZIP that group already uses, which is how a portfolio loses no member to a typo in a management address.

One signal alone is not enough. Dozens of unrelated companies file from a single attorney's or title company's address, and grouping on that would invent a landlord who does not exist. Roughly seven in ten shared-address groups in the deed record fail this test and appear nowhere on this site. A transfer between two companies in the same family is not counted as a sale, and condominium unit deeds collapse to the building they sit in, so a whole-condo purchase does not read as a portfolio.

What that leaves is a documented link, not a finding about ownership. The deeds say these companies share a name and a mailing address. They do not say who controls them.

Common questions

What is an entity family?

A group of limited liability companies that the public deed record links to each other, usually because they share a naming pattern and file from the same address. NYC property is commonly held one building per company, so a single operation appears in the record as dozens of unrelated strangers. These pages put them back together.

How are the companies linked?

Two independent things in the record have to agree: a shared naming stem across numbered siblings, and a shared filing address corroborated by a distinctive token that at least half the companies at that address carry. One signal alone is not enough. Dozens of unrelated companies file from a single attorney's or title company's address, and grouping on that would invent a landlord who does not exist. Roughly seven in ten shared-address groups in the deed record fail this test and appear nowhere on the site.

Does this prove common ownership?

No, and nothing here claims it. The deeds say these companies share a name and a mailing address. They do not say who controls them. Confirming that means a New York Department of State entity search, or asking the parties.

Why do some families hold nothing?

Because they have sold everything. A portfolio being unwound is as much a family as one being assembled, and often the more interesting one: it is the shape that shows a bulk exit.

A deed names the buyer of record. It says nothing about how a building is run. How PulseCities reads the record
