The NYC Department of Finance's 2026/27 assessment roll lists 35TH & 9TH LLC as the owner of record of 440 Ninth Avenue (BBL 1007580082). 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.

440 Ninth Avenue last sold in August 2025 for $105 million, according to the deed recorded with the city. 440 NINTH AVENUE OWNER LLC sold it to 35TH & 9TH LLC. That comes to about $306 per square foot of floor area. The deed is ACRIS document 2025082900511001 (BBL 1007580082) 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.

440 Ninth Avenue reported an ENERGY STAR score of 87 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 87 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 66.5 kBtu per square foot, 47% below the national median of 125.3 for a similar property. Its greenhouse gas emissions were about 2,301 metric tons of CO2e (6.6 kg per square foot).

At its 2024 energy use, 440 Ninth Avenue comes to about 1,776 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 2,814 tons for 2024 to 2029 (63% of the limit), so it would owe no penalty. From 2030 the limit drops to 993 tons and the same energy use counts as about 1,049 tons, about 56 tons over, or an estimated $15,000 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.
