Augrented Insights Report for 523 Knickerbocker Avenue

523 Knickerbocker Avenue is a 4-story, 8-unit apartment building constructed in 1905 in Bushwick, currently owned by Maurice Sohaye. The building has experienced persistent heating issues in recent months, with two separate heating system failures reported in late 2024 and early 2025, both of which were temporarily resolved before inspection verification.

Previous emergencies included a carbon monoxide detector issue in January 2019, a fire escape situation in April 2019, and various maintenance problems in late 2018 affecting an apartment on the 4th floor (4L), including defective doors, a leaking roof, compromised plaster surfaces, lighting problems, and an incident involving window repairs. The building's maintenance history shows some systematic address of these issues, with multiple violations being closed, though one ceiling repair violation from 2018 remains open.

In terms of pest control, the building has maintained a clean record in recent years, with no reported bedbug infestations in the past four annual Bedbug Reporting periods from 2021 through 2025, and the most recent Bedbug Report from June 2025 indicates zero infested units. Rat activity has been a recurring concern, with multiple inspections: while the most recent inspection in May 2025 passed, there were several previous instances of rat activity noted between 2023 and 2024, though some subsequent inspections showed improvements with rat activity being resolved. The building's most recent rodent inspections in 2024-2025 show both compliance and initial inspections with passing results, indicating ongoing monitoring and improvements to pest management systems.
