1251 3rd Avenue, Manhattan, NY 10021
1251 3rd Avenue is a 4-story, 149-unit residential building constructed in 1966 in Manhattan's Upper East Side. The property, currently owned by Neal Rosenberg, has experienced several maintenance issues in 2025, with multiple complaints received in June including unsanitary conditions (sewage and mold), plumbing problems (toilet), and door/window issues.
Notably, this building has an active violation as of January 2025 regarding failure to certify correction on an immediately hazardous violation. A significant cluster of violations was documented in September 2024 involving apartment 16D, including defective smoke and carbon monoxide detectors, self-closing door issues, and problems with floor tiles and ceiling paint.
The building has a history of safety-related concerns, with egress-related complaints in 2019, and the Department of Buildings issued several environmental control board violations between 2018-2024 regarding construction and safety compliance. However, there is some positive news regarding pest management, as recent bedbug reports from 2023-2024 show no infestations, and rodent inspections from 2010-2023 have consistently passed. The building's maintenance history shows regular reporting for required inspections, though there have been some compliance issues noted, particularly regarding parking structure inspections.
