Augrented Insights Report for 309 Knickerbocker Avenue

The 6-unit, 4-story building at 309 Knickerbocker Avenue in Bushwick, owned by Sam Kafif, has a documented history of maintenance issues since at least 2020. Most recently, in September 2024, two emergency complaints regarding mold were filed and subsequently closed without violations being issued. The building has experienced recurring issues with heat and hot water, with multiple complaints spanning 2022-2023, though in most cases, residents reported restoration of services during inspections.

Electrical problems were notable in December 2020, including a power outage and complete loss of lighting, though no violations were recorded following these incidents. The property has also faced rodent-related challenges, with multiple inspections between 2022 and 2025 confirming rat activity, most recently in June 2025. Current open violations include issues with fire escape egress on the third story (2023), and requirements regarding bedbug reporting (2022-2024).

A recent violation was issued in September 2024 for failure to file the 2023 external low pressure inspection. The building's maintenance history shows regular inspections and attempts to address various issues, with contractors being active on-site between 2019-2020, including work related to plumbing and electrical systems. While many complaints have been resolved through inspections or repairs, the recurring nature of heat, electrical, and rodent issues suggests ongoing maintenance challenges.
