The NYC Department of Finance's 2026/27 assessment roll lists FULTON SQUARE, LLC as the owner of record of 523 Fulton Street (BBL 3001460053). 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.

523 Fulton Street'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 33.1 kBtu per square foot, less than half the national median of 92.6 for a similar property. Its greenhouse gas emissions were about 390 metric tons of CO2e (3.42 kg per square foot).

At its 2024 energy use, 523 Fulton Street comes to about 297 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 1,275 tons for 2024 to 2029 (23% of the limit), so it would owe no penalty. From 2030 the limit drops to 178 tons and the same energy use counts as about 168 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.

In the 12 months to October 2026, the Department of Buildings issued first permits for 6 jobs at 523 Fulton Street.

These are the Department of Buildings' DOB NOW work permits for tax lot 3001460053. A permit is approval to do the work; it does not say who the work is for or whether it is finished.
