4122 10th Avenue, Brooklyn, NY 11219

The 4-story, 12-unit tenement building at 4122 10th Avenue in Borough Park, constructed in 1922, has experienced several significant maintenance and safety issues over recent years. Most recently, in 2025, there were complaints about unsanitary garbage storage and lighting issues, though HPD inspections found no violations in the former case, and the latter inspection was unable to be completed. A concerning pattern of maintenance delays is evident, with multiple instances of HPD being unable to complete inspections for complaints about cooking gas (2024) and window conditions (2021), as well as inspections showing either rat activity or compliance issues in 2025.

The building has a history of emergency maintenance requests, particularly regarding heating and hot water systems (2022), and multiple complaints about pests (2021). The property has also accumulated several active violations as of June 2023 for failing to file required External Low-Pressure Inspection reports for the years 2018-2021, though these violations are administrative in nature. Previous maintenance issues have included electrical wiring problems, window repairs, and various plumbing concerns documented in 2020-2021.

Notably, the building has maintained a clean record regarding bedbug infestations, with zero reported cases in the past eight reporting periods (2019-2024). While rodent inspections have shown mixed results over the years, the most recent (2025) inspection passed, indicating some improvement in pest management. The owner, Charles Rosenwasser, has made efforts to address building violations when documented, as evidenced by multiple certifications of correction between 2020-2021, though the pattern of recent complaints suggests ongoing maintenance challenges.
