To find who owns a New York City building, convert its address to a BBL (Borough-Block-Lot), pull the most recent deed in ACRIS, and read the grantee — that is the legal owner of record. When the owner is an LLC, the deed, mortgage and related filings usually name the person behind it. Crezly does all three steps for you on each building page.
Every NYC tax lot has a unique Borough-Block-Lot number. Once you have the BBL you can pull every public record tied to that lot. Enter an address on the Crezly property map or search it on the data suite and the BBL is resolved for you.
ACRIS is the city's register of deeds and mortgages. The grantee on the most recent deed is the current owner of record. Most commercial buildings are held by an LLC, so the grantee will read like "123 MAIN STREET OWNER LLC" rather than a person's name.
The LLC name, the mortgage documents, and the entity's other filings usually point to the principal. For the full method — including portfolio and skip-trace techniques — see how to find a property owner (even behind an LLC) and how to skip trace a property owner.
Crezly rolls every building an owner controls into one owner portfolio page, so you can see whether the LLC behind one address is part of a much larger holding.
What is the fastest way to find a building's owner?
Look up the building's BBL from its address, then read the grantee on the most recent ACRIS deed. Crezly shows the owner of record on each building page automatically.
Can I find who owns a building held by an LLC?
Usually yes. The deed, mortgage and assignment filings tied to the LLC, plus its portfolio of other holdings, typically point to the principal behind the entity.
Is NYC building-ownership data free?
The underlying ACRIS and PLUTO records are public. Crezly aggregates and cross-references them; verified owner contact details are a gated premium feature.
