Augrented Insights Report for 724 Knickerbocker Avenue

The 6-unit, 3-story 724 Knickerbocker Avenue building in Bushwick, owned by Roberto Mateo, has a considerable history of heat and hot water issues affecting the entire building. There have been five documented incidents between 2019 and 2024, with the most recent occurring in January 2024, though heat and hot water were reportedly restored in that instance.

The building is also facing ongoing compliance issues, with three open violations related to the failure to file the required annual bedbug reports between 2022 and 2024. Additionally, there is an active violation from April 2023 regarding the failure to file the 2022 external low-pressure inspection. The property has experienced security and maintenance concerns, including a period of rat activity in summer 2021, though subsequent inspections in 2022 and 2024 showed no further issues.

There were also two safety violations in January 2022 regarding broken and missing glass at the building entrance, which were subsequently resolved. The building has undergone rodent inspections showing mixed results, with the most recent inspection in April 2025 resulting in a failure for "Other Reasons." A complaint regarding an alleged illegal conversion was filed in January 2022, but inspectors were unable to gain access on multiple attempts. While the building has passed several rodent inspections and had some maintenance issues resolved, the persistent problems with heat and hot water, bedbug report compliance, and the recent rodent inspection failure suggest ongoing maintenance challenges.
