The NYC Department of Finance's 2026/27 assessment roll lists 345 7TH AVENUE REALTY OWNER LLC as the owner of record of 345 Seventh Avenue (BBL 1008050003). 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.

345 Seventh Avenue last sold in January 2025 in a $73 million sale that covered 4 tax lots, this one among them, according to the deed recorded with the city. 7TH CITY REALTY LLC and EMPIRE 345 SEVENTH LLC sold it to 345 7TH AVENUE REALTY OWNER LLC. The deed is ACRIS document 2025010800879001 (BBL 1008050003) 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.

345 Seventh Avenue reported an ENERGY STAR score of 98 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 98 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 20.8 kBtu per square foot, less than half the national median of 67.3 for a similar property. Its greenhouse gas emissions were about 487 metric tons of CO2e (2.39 kg per square foot).

At its 2024 energy use, 345 Seventh Avenue comes to about 358 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 1,544 tons for 2024 to 2029 (23% of the limit), so it would owe no penalty. From 2030 the limit drops to 548 tons and the same energy use counts as about 180 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.
