How to find who owns any NYC building

Source: 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.

Estimated from the owner's 2024 Local Law 84 filing, which reports energy by source and floor area by use: Office 199,365 SF. It applies the coefficients and per-use limits in Department of Buildings rule 1 RCNY 103-14 and Administrative Code 28-320.3.1.1 (as the Department lists them) and the $268 per ton penalty, checked 2026-10-04. It is not the building's Local Law 97 report: that report can count renewable energy credits, solar and storage deductions and, for 2024 and 2025, the law's occupancy group limits where higher, and penalties can be reduced for good faith efforts.

Source: NYC Department of Buildings, DOB NOW: Build Approved Permits, pulled 2026-10-24 (permits issued through 2026-10-22). A job counts once, when its first permit is issued; renewals are not new work. A build-out groups jobs on the same floors first permitted within 120 days of each other. 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.

Under Local Law 33, as amended by Local Law 95 of 2019, a score of 85 or higher earns an A, 70 to 84 a B, 55 to 69 a C and under 55 a D, so 86 earns an A.
