The NYC Department of Finance's 2026/27 assessment roll lists 605 THIRD AVENUE FEE LLC as the owner of record of 605 Third Avenue (BBL 1009200012). 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 605 Third Avenue. 3 investment managers and funds file 13F holdings reports from the address: Amova Asset Management Americas, Inc.; Global X Management CO LLC; and GLOBAL X MANAGEMENT COMPANY, 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.

605 Third Avenue reported an ENERGY STAR score of 76 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 76 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 68.6 kBtu per square foot, 32% below the national median of 101.5 for a similar property. Its greenhouse gas emissions were about 6,115 metric tons of CO2e (6.54 kg per square foot).

At its 2024 energy use, 605 Third Avenue comes to about 4,411 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 7,249 tons for 2024 to 2029 (61% of the limit), so it would owe no penalty. From 2030 the limit drops to 2,675 tons and the same energy use counts as about 2,748 tons, about 74 tons over, or an estimated $20,000 a year unless the building cuts its emissions. 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.
