1733 1st Avenue, Manhattan, NY 10128
1733 1st Avenue is a 6-story, 41-unit New Law Tenement building constructed in 1930, currently owned by Greg Katz. The building has experienced several significant maintenance issues in recent years, with particular concern about building systems and pest control. Most recently, there were complaints in May 2025 about electrical lighting issues and in April 2025 related to food establishment concerns.
Notable recurring problems include multiple instances of inadequate heat and hot water (emergency complaints in December 2024 and January 2021), unsanitary conditions including mold (July and May 2024), and pest-related issues (July 2023 and February 2022). The building's electrical system has shown ongoing concerns, with a 2025 violation regarding countertop receptacle outlet spacing requirements and previous electrical wiring complaints. The property has also faced structural and safety challenges, with building shaking/vibration complaints recorded in October 2023 linked to exhaust fan issues, though these were ultimately resolved through a violation.
Various apartment maintenance issues have been documented, including a 2024 violation regarding defective cabinetry in Apartment 3C and multiple violations in Apartment 5D from 2020 related to safety equipment (carbon monoxide detector, smoke detector) and door issues. The building's maintenance record shows regular inspections and efforts to address violations, with the most recent bedbug reporting (for 2023-2024) indicating no reported infestations. However, rodent inspections in 2024 and 2025 showed varying results, with some inspections passing and others noting rat activity or other issues, suggesting ongoing challenges with pest control. The property has active Department of Buildings violations regarding FISP Cycle 8C Technical Report filing requirements from 2019 and 2020, indicating possible concerns with building facade maintenance compliance.
