The NYC Department of Finance's 2026/27 assessment roll lists 19-20 BUSH TERMINAL OWNER LP as the owner of record of 4000 1st Avenue (BBL 3007100001). 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.

4000 1st Avenue last sold in April 2004 in a $44 million sale that covered 2 tax lots, this one among them, according to the deed recorded with the city. BUSH REALTY ASSOCIATES LLC and KAVDO LLC sold it to 19-20 INDUSTRY CITY ASSOCIATES, LLC. The deed is ACRIS document 2004050701078001 (BBL 3007100001) 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.

4000 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 20.9 kBtu per square foot. Its greenhouse gas emissions were about 1,822 metric tons of CO2e (1.73 kg per square foot). The filing covers 2 tax lots together, so these figures are for the whole property.

At its 2024 energy use, 4000 1st Avenue comes to about 1,502 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 7,859 tons for 2024 to 2029 (19% of the limit), so it would owe no penalty. From 2030 the limit drops to 1,582 tons and the same energy use counts as about 1,059 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.

The Department of Buildings issued no permits for new jobs at 4000 1st Avenue in the 12 months to October 2026; the last one was first permitted in October 2024. These are the Department of Buildings' DOB NOW work permits for tax lot 3007100001. A permit is approval to do the work; it does not say who the work is for or whether it is finished.
