NYC LLC directory, A to Z

What these names are

When a NYC building changes hands, the deed is recorded with the city and both sides are named on it. Most of the time the name on the buyer's line isn't a person — it's a company formed to hold that one building, or that one block, or that one fund's worth of buildings. This directory lists the company names that appear on five or more of those records.

Names are shown as they were filed. The city doesn't clean them up, and neither do we: the same operator can appear as three slightly different spellings, and two unrelated companies can share a generic name. A name here is a starting point for a search, not a verdict about who controls a building.

What you get when you open one

Each company page lists the buildings the name appears on, the dates those records were filed, and the party on the other side of the transaction. From any building you can open the full report — open violations, complaint history, and the rating that comes out of them.

That's the useful part of a deed record: it isn't a list of what a landlord owns today, it's a list of when things moved and who was standing there when they did. Buildings sell. Violations don't clear on sale — they stay with the building for the next owner to cure.

How to use the directory

Pick the first letter of the company name. Numbered names — the 123 Main Street LLC pattern, which is most of them — sit under 0–9. Each letter page is ordered by how many buildings the name appears on, so the operators with real portfolios sit at the top.

If you already know the address and want the owner rather than the company, start from the building instead. The report names the registered owner and managing agent, and links out to the portfolio behind them.

Common questions

Why is my building owned by an LLC I've never heard of?

Single-asset LLCs are the normal way NYC property is held. The company is often formed for one building and named after its address, which is why so many entries here read like a street sign. It doesn't imply anything is wrong — it just means the name on the deed isn't the name of a person.

How do I find the person behind an LLC?

Two paths. Housing registration filings name a head officer and a managing agent for most residential buildings with three or more units, and those names carry across a portfolio. Deed records name the signing parties. Brix links both from the building report, so you can move from the address to the company to the people filed against it.

Does an LLC on this list still own the building?

Not necessarily. This directory is built from recorded transactions, so a name stays on the record for a sale that closed years ago. Current ownership is shown on the building report, which reads from the most recent registration and deed on file.

Why do some companies appear more than once?

Because the record does. Party names on deeds are typed by hand and arrive with abbreviations, missing punctuation, and occasional misspellings. We show what was filed rather than merging names that only look alike — a bad merge would attribute buildings to the wrong company.

Is this free?

Yes. Company pages, building reports, ratings, and landlord portfolios are free and need no account. Only unit-level apartment history and ongoing change alerts are paid.
