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.

NYC energy benchmarking (Local Law 84)
Energy use and emissions
41 East 51st Street's 2024 Local Law 84 benchmarking filing got no ENERGY STAR score, and Local Law 33 letter grades come from that score, so the filing does not yield an A to D grade. Its site energy use came to 12.5 kBtu per square foot, less than half the national median of 51.2 for a similar property. Its greenhouse gas emissions were about 466 metric tons of CO2e (1.24 kg per square foot).

Local Law 97 emissions limit
At its 2024 energy use, 41 East 51st Street comes to about 336 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 2,850 tons for 2024 to 2029 (12% of the limit), so it would owe no penalty. From 2030 the limit drops to 1,014 tons and the same energy use counts as about 201 tons, still under the limit.

Estimated from the owner's 2024 Local Law 84 filing, which reports energy by source and floor area by use: Office 370,479 SF; Food Service 1,325 SF; Retail Store 3,421 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.

Does 41 East 51st Street have an energy grade?
