Find a property owner in Suffolk County, New York

Updated October 2026 · Suffolk County, New York

Suffolk County takes in Long Island and the surrounding area. In New York, deeds are recorded by the county clerk (the City Register in New York City), and property is assessed by the city or town assessor. Those offices give you the owner of record and mailing address one parcel at a time; for a whole list, an owner-data tool returns owners, phones (DNC flagged) and emails in one pass.
