Augrented Insights Report for 843 Knickerbocker Avenue

843 Knickerbocker Avenue is a three-story, six-unit New Law Tenement building located in Bushwick, constructed in 1906 and currently owned by Nelo Rojas. The building has experienced consistent challenges with pest management, particularly regarding rodents, with multiple inspections between 2022 and 2025 showing repeated rat activity. Most recently, rodent issues were documented in inspections conducted in April and May 2025, following a rat sighting complaint in May 2024.

The property has also had ongoing bedbug reporting requirements, with violations noted in 2021-2024 for failure to file annual bedbug reports as mandated by HPD regulations. Despite these violations, the most recent bedbug report filed in March 2025 for the period of November 2023 to October 2024 shows no infested or re-infested units. The building has two significant outstanding violations with the Department of Buildings from June 2023 related to the failure to file low-pressure inspection records for 2019-2021, though these violations are categorized as active.

This pattern of non-compliance with both pest control regulations and building safety inspections suggests ongoing maintenance challenges. The property's historical rodent inspection records show a mix of passed and failed inspections between 2012 and 2013, with the most recent inspections continuing to indicate rodent activity despite compliance inspections in 2024 and 2025. While the bedbug situation appears to be currently under control with no reported cases in the latest filing period, the building's pest management history shows persistent challenges that merit attention.
