The NYC Department of Finance's 2026/27 assessment roll lists 909 THIRD HOLDING LLC as the owner of record of 909 Third Avenue (BBL 1013280001). 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.

909 Third Avenue last sold in June 2021 for $191.7 million, according to the deed recorded with the city. 909 THIRD FEE OWNER LLC sold it to 909 THIRD HOLDING LLC. That comes to about $145 per square foot of floor area. The deed is ACRIS document 2021061401235002 (BBL 1013280001) in the city's property records. A sale of the company that owns a building is not recorded as a deed, so it would not show there.

909 Third Avenue reported an ENERGY STAR score of 93 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 93 earns an A. 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 54.1 kBtu per square foot, less than half the national median of 122.8 for a similar property. Its greenhouse gas emissions were about 6,416 metric tons of CO2e (5.08 kg per square foot).

At its 2024 energy use, 909 Third Avenue comes to about 4,605 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 9,720 tons for 2024 to 2029 (47% of the limit), so it would owe no penalty. From 2030 the limit drops to 3,555 tons and the same energy use counts as about 2,922 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.
