How to find who owns any NYC buildingSource: NYC Department of Finance, Property Valuation and Assessment Data (2026/27 roll; owner names as the roll records them, which cuts some long names short), pulled 2026-10-16; tax rate from the Department of Finance tax rates page, checked 2026-09-28. The estimate is the taxable value times the class rate. It leaves out abatements, payment-in-lieu-of-taxes agreements and charges, so the actual bill can differ.
