The NYC Department of Finance's 2026/27 assessment roll lists MAIDEN & NASSAU LLC as the owner of record of 56 Nassau Street (BBL 1000670023). 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.

56 Nassau Street last sold in February 2012 in a $207.5 million sale that covered 2 tax lots, this one among them, according to the deed recorded with the city. MERIT US REAL ESTATE FUND III, L.P. sold it to FEDERAL RESERVE BANK OF NEW YORK. The deed is ACRIS document 2012030701149001 (BBL 1000670023) 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.

56 Nassau Street reported an ENERGY STAR score of 80 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 80 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 58.4 kBtu per square foot, 33% below the national median of 86.8 for a similar property. Its greenhouse gas emissions were about 3,144 metric tons of CO2e (5.85 kg per square foot).

At its 2024 energy use, 56 Nassau Street comes to about 2,276 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 4,251 tons for 2024 to 2029 (54% of the limit), so it would owe no penalty. From 2030 the limit drops to 1,601 tons and the same energy use counts as about 1,342 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.
