4912 7th Avenue, Brooklyn, NY 11220

The 6-unit, 3-story building at 4912 7th Avenue in Sunset Park, owned by Lizhu Zhu, has experienced several concerning maintenance issues in recent years, particularly between 2022-2024. Most notably, there was a persistent rodent problem in 2022, with multiple complaints recorded between August and October 2022, and two inspections in December 2022 and October 2022 confirming "Rat Activity." The building has also faced recurring heat and hot water issues, with multiple complaints filed through HPD in January 2022, some being duplicates of previously reported problems, indicating possible systemic heating system failures.

More recently, in October 2024, the building underwent inspections revealing multiple safety concerns, including defective smoke and carbon monoxide detectors, problematic door/window frames, and issues with window guards. Violations were issued for encumbrances blocking public hallways on the 2nd and 3rd stories, though these were later closed. The building's safety systems have been a particular focus, with separate violations noted for a defective self-closing door mechanism in the vestibule.

While the building is required to file annual bedbug reports, the most recent filings from 2025 show no infested units or reported infestations. A previous bedbug-related violation from April 2024 regarding the annual report filing was closed. Despite multiple violations and repeated complaints, the property has shown some responsiveness to inspections, though the pattern of recurring issues suggests potential ongoing maintenance challenges.
