How to find the owner behind an LLC on a NYC commercial property (2026)

Of the 155,860 active commercial mortgages of $1 million or more in New York City's four ACRIS boroughs, 91,685 — 59% — are held by an LLC, corporation, partnership or trust, and those loans average $14.3 million against $4.6 million for the ones held in a person's name. The bigger the deal, the more certain it is that the recorder will hand you a shell with a street address for a name. Every broker who works maturities runs into the same wall: the loan is real, the maturity is real, and the borrower is "1140 [STREET] OWNER LLC".

The obvious hope — that the state would finally publish who is behind these entities — was cancelled before it started. New York's LLC Transparency Act took effect on January 1, 2026, but the chapter amendment that made it law removed the public database; beneficial-owner filings go into a system open only to government agencies and law enforcement. For a broker, the Act changes nothing.

What does answer the question is a set of city records that each, for their own reasons, require a natural person's name. None of them covers everything. So rather than list them, we measured them: for every active NYC commercial loan over $1 million, which public records name a person tied to the borrower, its building, or the instrument itself? The answer is that 85% of loans have at least one, and the sources rank in a way that is worth knowing before you spend money on a data vendor.

Active liens above $1 million, four ACRIS boroughs. A loan counts for a source if that source names a natural person on any parcel securing the loan, on the borrower entity, or on the recorded instrument. Measured 2026-08-29.

1. The HPD registration: the officers an LLC must name

Every multiple dwelling in New York — three or more residential units — must be registered with the Department of Housing Preservation and Development each year under Housing Maintenance Code §27-2097. The statute is the reason this record is so good: when the owner is a corporation, the registration must include the names and business addresses of its officers and of any person whose share of ownership exceeds twenty-five percent; and every registration must designate a managing agent who is a natural person over 21 with a residence or business office in the city. HPD needs someone to serve with legal notice, so a shell will not do.

The city publishes the whole thing as open data. Registrations (203,887 of them) map to a borough, block and lot; contacts (782,000 rows) hang off each registration with a type — HeadOfficer, Officer, Shareholder, IndividualOwner, JointOwner, Agent, SiteManager — and a name, title and business address. For a building held by "141 [Street] Owner LLC" you get, in the registration's own words, something like "J. Doe, Principal, 141 [Street], New York NY" — a person, a title, a business address.

Across our loan book, an HPD registration names an officer or owner for 45.7% of active commercial loans over $1 million, and a managing agent for 44.0%. That is the ceiling for this source, and it is a structural one: HPD registers residential buildings. Office, retail, industrial, hotel and land have no registration, so the coverage is really "most of multifamily" and "none of the rest".

Two things to know when reading it. The HeadOfficer is usually the principal — the person who can say yes to a refinance — while an Agent is the management company's employee, who can route you to ownership but does not decide anything. And the addresses are business addresses: for a small landlord that is often their home; for an agent it is the management office.

2. The signature page of the recorded instrument

This is the source nobody uses, because it is not in any index. ACRIS's structured data gives you the mortgagor as "1140 [STREET] OWNER LLC" and nothing more. But ACRIS also serves the scanned instrument, page by page, and a mortgage or consolidation agreement has to be signed — by a person, in a stated capacity, with a notary acknowledgment recording who appeared:

By: /s/ [signature] — Jane Doe, Managing Member

That line is the borrower's decision-maker, in the borrower's own filing, with the title the borrower chose. It is also, in provenance terms, the best evidence there is — read off the recorded document rather than compiled from it.

We read the last pages of 59 instruments on active loans and found a named borrower-side signer with a title on 44 (75%). The mechanics matter if you try this by hand: the signature block and the acknowledgment sit just before Exhibit A (the legal description) and the riders, so on a typical 34-page mortgage they are around pages 25–30, not the last page. ACRIS does not tell you how many pages a document has — it serves a placeholder image past the end rather than an error — so you page forward until the scans stop being scans. Consolidation agreements and CEMAs are signed by both sides; take the mortgagor's block, not the bank's.

The signer's name comes with no address of its own. Pair it with the mortgagor's mailing address from ACRIS Parties, which is on the same document and is usually where the LLC's principal actually receives mail.

3. DOB NOW permit filings: the owner on every job

Every permit application filed with the Department of Buildings since 2019 names the property owner — first name, last name, owner type, and for a corporation the business name. It is filed by the owner's architect or expediter, so the "owner" is whoever they typed, and on a large project it is sometimes the construction manager's contact rather than the principal. But it covers the buildings HPD does not: a permit gets pulled on an office lobby renovation or a retail build-out just as it does on an apartment building.

DOB NOW owners exist for 42.6% of loans in our book, and the overlap with HPD is only partial — which is why the combined number is so much higher than either alone. Weight it below the HPD officer and the signer, and above nothing.

4. When the borrower is a person after all

For 33.4% of loans the recorder or the assessor already names a natural person: the mortgagor of record is "SMITH, JOHN" rather than an LLC, or the assessor's owner of record is. These are the smaller loans — the $4.6 million average above — and they come with the best address of all: the mortgagor's mailing address on the ACRIS Parties record, which is where the bank sends the statements.

5. What the state gives you (and doesn't)

The Department of State's entity search returns the LLC's name, county, formation date, and an address where the Secretary of State will forward process — often the formation service's address, not the owner's. It does not list members or managers, and the LLC Transparency Act does not change that for the public. Use it for one thing: confirming the exact legal name and formation date when two similar LLCs are in play.

Together: 85% of loans, and a clear order of preference

Stacked, the sources name at least one person for 85.1% of active NYC commercial loans over $1 million. The remaining 15% skew commercial (no HPD), permit-quiet (no DOB), and held in an entity (no person of record) — which is exactly the population where the signature page earns its keep, and why we read it on demand rather than for every loan.

When a loan has several names, rank them by how close they stand to the decision:

1. The signer of the instrument — committed the entity to the loan.
2. HPD officers, owners and >25% shareholders — the entity's own filing of who runs it.
3. The person of record (mortgagor or assessor owner) — the small-landlord case.
4. DOB filing owners — real people, sometimes one step removed.
5. Managing agents — the door, not the decision-maker.

From a name to a phone number: where the money goes wrong

A name and an address are what a skip-trace vendor needs; the vendor's job is to turn them into phones and emails. We tested one of the largest, BatchData, on names from the records above, and the result is a lesson about what to key the lookup on.

Property-skip-trace products take an address and return the people they associate with it. Keyed on the building — the collateral — the vendor returned a tenant or a prior resident for every one of 25 HPD officers we asked about, and never the officer. Keyed on the officer's own registered address from the HPD filing, 4 of 10 came back with the right person: a shareholder with five phone numbers and three emails, a joint owner with a work email, a partner with an office line. Managing agents at a management-office address matched 0 of 6, because the vendor's answer for an office building is its occupants. For agents, skip the vendor and call the company.

Two guards are non-negotiable. Accept a vendor answer only when the returned name matches the person you asked about — a match on the address alone is a stranger's phone number with a bill attached. And keep the vendor's Do-Not-Call and TCPA-litigator flags on every number; calls to a DNC number and any autodialed or prerecorded call without consent are the fastest way to turn a prospecting list into a lawsuit.

How Circlemark does it

Every loan on Circlemark carries the people the public record ties to it — HPD officers and agents, DOB owners, the person of record, and the instrument's signer where we have read it — and shows, before any click, who is there by role and source: "Head officer · HPD registration", "Managing Member · signed the recorded instrument". One credit unlocks the names, firms and addresses for that borrower, with each source and provenance tier next to the name, and includes phone numbers and emails where a vendor has them for that exact person (the vendor is asked at the person's own address, and its answer is accepted only if the name matches). Where the public record names nobody, the click reads the instrument's signature pages on the spot.

That is the difference between a contact database and a public-record method: you can see why a name is there, and you only pay when it turns into a way to reach someone.
