The NYC Department of Finance's 2026/27 assessment roll lists 110 WILLIAM PROPERTY INVESTORS III, LLC as the owner of record of 110 William Street (BBL 1000770008). 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.

110 William Street last sold in May 2014 for $261.1 million, according to the deed recorded with the city. 110 WILLIAM, LLC sold it to 110 WILLIAM PROPERTY INVESTORS III, LLC. That comes to about $331 per square foot of floor area. The deed is ACRIS document 2014050600120001 (BBL 1000770008) 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.

110 William Street's 2024 Local Law 84 benchmarking filing got no ENERGY STAR score, and Local Law 33 letter grades come from that score, so the filing does not yield an A to D grade. Its site energy use came to 45.1 kBtu per square foot, 23% below the national median of 58.5 for a similar property. Its greenhouse gas emissions were about 3,211 metric tons of CO2e (4.07 kg per square foot).

At its 2024 energy use, 110 William Street comes to about 2,292 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 5,988 tons for 2024 to 2029 (38% of the limit), so it would owe no penalty. From 2030 the limit drops to 2,119 tons and the same energy use counts as about 1,522 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.
