The NYC Department of Finance's 2026/27 assessment roll lists 5601 REALTY LLC as the owner of record of 5601 1st Avenue (BBL 3008360005). 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.

5601 1st Avenue last sold in April 2012 for $5 million, according to the deed recorded with the city. SHORECOR REALTY LLC. sold it to 5601 REALTY LLC. The deed is ACRIS document 2012040401124001 (BBL 3008360005) 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.

5601 1st Avenue's 2024 Local Law 84 benchmarking filing got no ENERGY STAR score (no single use that ENERGY STAR scores covers more than half of the floor area), 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 158.4 kBtu per square foot. Its greenhouse gas emissions were about 469 metric tons of CO2e (11.11 kg per square foot).

At its 2024 energy use, 5601 1st Avenue comes to about 413 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 320 tons for 2024 to 2029: about 93 tons over, an estimated penalty of $25,000 a year. From 2030 the limit drops to 60 tons and the same energy use counts as about 336 tons, about 276 tons over, or an estimated $74,000 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.
