442 51st Street, Brooklyn, NY 11220

The four-story, eight-unit tenement building at 442 51st Street in Sunset Park, owned by ADG 442 Realty Co LLC, has experienced several significant maintenance and safety issues in recent years. Most notably, there have been recurring indoor air quality concerns in early 2025, with two separate complaints about chemical vapors, gases, or odors reported to DOHMH in February 2025. The building has a problematic history with heat and hot water systems, evidenced by complaints in December 2022 and September 2023 regarding insufficient service throughout the entire building, though these issues were temporarily resolved according to HPD reports.

The 1L apartment specifically has been the focus of multiple recent violations, including issues with self-closing doors, hot water temperatures exceeding the 130-degree maximum, and problems with smoke and carbon monoxide detectors, all documented during a June 2024 inspection. The building's maintenance history shows persistent challenges with basic building systems and safety features. In 2024, multiple emergency violations were documented concerning safety equipment, including smoke and carbon monoxide detectors, as well as various door-related issues.

The property has also faced concerns regarding cooking gas supply to the kitchen fixtures in 2023. While there have been three illegal conversion complaints filed (in 2019, 2024, and as recently as 2025), access issues prevented inspections in some cases. The building has three active violations related to pressure inspections from 2019-2020 that remain unresolved, as per records from June 2023. On a more positive note, the building has maintained a clean record regarding bedbug infestations, with no reported cases from 2019 through 2024, and passed a rodent inspection in February 2023.
