The NYC Department of Finance's 2026/27 assessment roll lists 425 PARK AVE GROUND OWNER LLC as the owner of record of 425 Park Avenue (BBL 1013100001). 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.

425 Park Avenue last sold in November 2019 for $616.8 million, according to the deed recorded with the city. T-C 425 PARK AVENUE, LLC sold it to 425 PARK AVE GROUND OWNER LLC. That comes to about $925 per square foot of floor area. The deed is ACRIS document 2019120600855001 (BBL 1013100001) 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.

425 Park Avenue reported an ENERGY STAR score of 32 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 32 earns a D. 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 97.7 kBtu per square foot, 26% above the national median of 77.6 for a similar property. Its greenhouse gas emissions were about 6,852 metric tons of CO2e (9.79 kg per square foot).

At its 2024 energy use, 425 Park Avenue comes to about 5,272 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 5,400 tons for 2024 to 2029 (98% of the limit), so it would owe no penalty. From 2030 the limit drops to 1,913 tons and the same energy use counts as about 3,079 tons, about 1,166 tons over, or an estimated $312,000 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.
