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.

Costs are the estimates filed with the jobs. Jobs filed before DOB NOW (in the older BIS system) are not counted. A permit is approval to do the work; it does not say who the work is for or whether it is finished.
