The NYC Department of Finance's 2026/27 assessment roll lists EMMY ENTERPRISES LLC as the owner of record of 47 Onderdonk Avenue (BBL 4033940008). 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.

47 Onderdonk 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 51.9 kBtu per square foot. Its greenhouse gas emissions were about 205 metric tons of CO2e (4.27 kg per square foot).

At its 2024 energy use, 47 Onderdonk Avenue comes to about 190 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 364 tons for 2024 to 2029 (52% of the limit), so it would owe no penalty. From 2030 the limit drops to 68 tons and the same energy use counts as about 169 tons, about 101 tons over, or an estimated $27,000 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.
