Augrented Insights Report for 5605 4th Avenue

The 16-unit, 4-story tenement building at 5605 4th Avenue in Sunset Park, owned by Qui Liu, has experienced several significant maintenance and safety issues in recent years. Most notably, from March to April 2025, the building faced multiple emergency safety concerns, including problems with carbon monoxide detectors and smoke detectors, along with door-related issues. There are currently open violations from 2024 regarding missing smoke detectors and carbon monoxide detectors in Apartment 2B, and an unresolved 2024 violation related to not filing the annual bedbug report.

Earlier in 2024, the building experienced heating and power outage issues affecting the entire structure, though inspections did not result in any violations. A series of maintenance complaints filed in November 2023 regarding various issues including water leaks, plumbing problems, and multiple structural concerns (doors/windows, walls, and ceilings) could not be inspected due to access issues. The building has an active pest management situation as of 2024-2025, with violations related to unsanitary conditions and pest infestations.

Previous inspections from June 2023 revealed multiple violations requiring attention, including missing smoke detectors, carbon monoxide detectors, and issues with self-closing doors in Apartments 2A and 3A. Historical records show a rodent inspection in 2011 passed, but more recent violations from 2024 indicate ongoing pest problems. An illegal conversion complaint from December 2020 was filed but access for inspection was denied in March 2021. While some violations have been resolved, most notably several classified as "Closed" during 2025, many critical safety and maintenance issues remain open or were not fully addressed during inspections, indicating persistent building maintenance challenges.
