The NYC Department of Finance's 2026/27 assessment roll lists 101 PARK AVENUE ASSOCIATES II LLC as the owner of record of 101 Park Avenue (BBL 1012950001). 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. Deeds and mortgages for the lot are public in ACRIS, the city's property records system.

Leasemark does not have the building's tenant roster, but SEC filings name companies with offices at 101 Park Avenue. One public company reports the address as its principal executive office: FEDERAL HOME LOAN BANK OF NEW YORK. 2 investment managers and funds file 13F holdings reports from the address: FEDERATED GLOBAL INVESTMENT MANAGEMENT CORP; and Nippon Life Global Investors Americas, Inc.. Private companies do not file with the SEC, so the full list of tenants is longer, and a company can also report a building it owns.

101 Park Avenue reported an ENERGY STAR score of 71 for calendar year 2024 in its Local Law 84 benchmarking filing. 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 71 earns a B. The Department of Buildings assigns the grade a building posts, so the posted label can differ if a filing was corrected. Its site energy use came to 73.4 kBtu per square foot, 26% below the national median of 99 for a similar property. Its greenhouse gas emissions were about 7,871 metric tons of CO2e (7.23 kg per square foot).
