Augrented Insights
AI summary · updated June 2026

640 Coster Street is a two-story, three-unit residential building located in Hunts Point, constructed in 1910 and currently owned by Manuel Singelin. The building has several significant open violations related to bedbug reporting requirements, with the most recent violation recorded in April 2024, and previous violations in March 2023, February 2022, and April 2021, indicating an ongoing issue with compliance regarding mandatory bedbug reporting. Recent maintenance concerns have been documented, including unsanitary conditions relating to pests and flooring issues in August 2023, though the Housing Preservation and Development (HPD) department was unable to gain access for inspection in these cases.

The building has successfully passed multiple rodent inspections over the years, with the most recent inspection showing compliance in March 2025, and previous successful inspections recorded in September 2023, and earlier dates back to 2010. The property has experienced recurring violations requiring annual bedbug reporting, with these violations remaining open as of summer 2025. While the building has an overall record of passing rodent inspections, the persistent bedbug reporting violations and recent complaints about flooring issues and pest problems suggest ongoing maintenance challenges that affect resident comfort and safety.
