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.

Local Law 97 of 2019, estimated
Local Law 97 emissions limit
At its 2024 energy use, 300 Madison Avenue comes to about 6,727 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 8,854 tons for 2024 to 2029 (76% of the limit), so it would owe no penalty. From 2030 the limit drops to 3,215 tons and the same energy use counts as about 3,921 tons, about 706 tons over, or an estimated $189,000 a year unless the building cuts its emissions.

Estimated from the owner's 2024 Local Law 84 filing, which reports energy by source and floor area by use: Office 1,123,417 SF; Data Center 12,000 SF; Retail Store 7,000 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.

This is an estimate from the owner's 2024 benchmarking filing using the coefficients and per-use limits in the law and the Department of Buildings rule, at $268 per ton over. It is not the building's Local Law 97 report, which can count credits and deductions this estimate cannot.
