Augrented Insights Report for 4721 8th Avenue

This 7-story, 18-unit residential building in Borough Park, owned by Zheng Zheng and constructed in 2008, has experienced recurring issues with heating and hot water systems, with three emergency complaints filed in 2021 (October 3, October 18) and two more in 2022 and 2025. Notably, during the 2021 complaints, HPD was able to verify inadequate heat or hot water in at least one apartment, leading to violations, while access issues were reported in subsequent complaints.

The building has also faced multiple maintenance challenges, including window and door issues (October 2021), multiple sanitation concerns related to pests (March-May 2021), and plumbing problems involving sinks and toilets (March 2021), all resulting in violations. More recent concerns include open violations from October 2021 related to heating system access and an October 2021 violation regarding hot water issues in 5B. The property has multiple outstanding Class A and B violations from July 2021 concerning public hall maintenance, including requirements for repainting, cleaning, and addressing encumbrances at 1st and 6th stories.

The building's elevator system has a history of issues, with multiple violations issued in 2019 for failure to correct defects noted during 2017 inspections, though these were subsequently dismissed. Notably, there have been no reported bedbug infestations since 2020, with the most recent bedbug report (filing period 2023-2024) showing zero infested units. The property has had some compliance issues with annual reports and notices, including a current open violation from 2024 regarding annual bedbug reporting requirements.
