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.

The NYC Department of Finance's 2026/27 assessment roll lists 525 DELAWARE LLC as the owner of record of 525 Seventh Avenue (BBL 1008140001). Big buildings are usually held through a company set up for that one property, so the name on the roll can differ from the landlord's brand or the managing agent.

What is the energy grade of 525 Seventh Avenue?
525 Seventh Avenue reported an ENERGY STAR score of 92 for calendar year 2024 in its Local Law 84 benchmarking filing.

Its site energy use came to 44.3 kBtu per square foot, less than half the national median of 95.6 for a similar property. Its greenhouse gas emissions were about 1,861 metric tons of CO2e (4.48 kg per square foot).

From 2030 the limit drops to 1,145 tons and the same energy use counts as about 949 tons, still under the limit. 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.
