Augrented Insights Report for 519 Knickerbocker Avenue

The 6-unit residential building at 519 Knickerbocker Avenue in Bushwick, owned by Justina Rodriguez, has experienced multiple maintenance challenges in recent years. The most significant issues emerged in early 2023, when the building faced multiple emergency complaints including unsanitary conditions (mold), electrical problems (no lighting), and paint/plaster issues.

These complaints led to violations being issued by the Department of Housing Preservation and Development (HPD), which remain notable given the building's current open violations status. As of 2024-2025, the building has several ongoing violations requiring attention, including improper window maintenance, plaster surface repairs, lighting issues, and concerns about mold.

The property also shows a pattern of rodent activity, with multiple inspections between 2023 and 2025 revealing rat activity, though recent inspections in April 2025 resulted in passing compliance. The building's management has also failed to provide required annual bedbug reports for 2021-2022, though the reported unit count for bedbug infestation during that period was recorded as zero. While there have been various maintenance complaints in the past, including window safety concerns and water leaks, the most pressing current issues appear to be related to the 3rd floor apartment's maintenance needs and the building's external inspection compliance.
