Augrented Insights Report for 422 45th Street

The three-unit, three-story tenement building at 422 45th Street in Sunset Park, owned by Dengyundi Chen, has experienced significant pest control challenges over the past two years, particularly concerning rodent activity. Most notably, between March 2024 and March 2025, there were multiple rat sightings reported to the Department of Health and Mental Hygiene (DOHMH), with inspections revealing violations in April 2024 when the Health Department found conditions requiring follow-up inspections.

The building underwent several rounds of rodent control measures, with bait being applied consistently from June to October 2024, though inspections in both May and June 2024 indicated ongoing rat activity. A recent rodent inspection in May 2025 did pass, suggesting some improvement in pest control measures. Additionally, the property has had recurring issues with bedbug reporting compliance between 2021 and 2023, with four Housing Maintenance Code violations issued for failure to file the required annual bedbug report, though no actual infestations were reported during any filing periods.

The most recent bedbug report filed in March 2025 for the period November 2023 to October 2024 indicated zero infested, eradicated, or re-infested dwelling units. The building also had one unsanitary condition complaint filed in April 2024 regarding garbage/recycling storage, which was inspected by the Department of Housing Preservation and Development (HPD) but resulted in no violations being issued. While some of these issues have been addressed, the building's historical challenges with both rodent activity and bedbug reporting compliance suggest that pest control and sanitation management will require continued attention.
