Augrented Insights Report for 533 Knickerbocker Avenue

The 8-unit, 4-story tenement building at 533 Knickerbocker Avenue in Bushwick, owned by Leib Flohr, has experienced several significant maintenance and safety issues in recent years. Most notably, there have been multiple heating and electrical problems, including two building-wide heat/hot water complaints in late 2024 that were classified as emergencies, and two electrical issues in 2025, one involving no lighting that resulted in violations being issued.

The building has also faced persistent pest and sanitation challenges, with complaints about mice and roaches in apartment 4L during late 2024, and multiple unsuccessful inspections regarding various unsanitary conditions in November 2024. In terms of safety concerns, inspections in late 2024 revealed multiple violations in apartments 3L and 4L that required attention, including issues with lead-based paint hazards, carbon monoxide detectors, smoke detectors, and fire escape obstructions in apartment 3L, and various maintenance issues in apartment 4L including problems with the roof, bathroom fixtures, and pest infestations.

The building's rodent inspections show a concerning pattern, with repeated rat activity detected in 2024, though recent inspections in 2025 passed. While there have been bedbug reports in past years, recent filings for 2022-2024 show no current infestations. The property was built in 1905 and underwent some documented improvements, with a permit issued in June 2020 for unspecified work.
