Augrented Insights Report for 643 9th Avenue

The five-story, 19-unit tenement building at 643 9th Avenue in Hell's Kitchen has experienced several ongoing maintenance issues since 2023, notably concerning pests and structural maintenance. Most concerning are the repeated pest-related complaints, with multiple HPD violations between 2024 and 2025 regarding rodents, unsanitary conditions, and garbage/recycling storage problems. The building has also faced significant open violations related to fire safety and building maintenance, including defective self-closing doors, fire retardant material issues, and water leaks.

There are active violations from 2020 regarding improper transient use of Apartment #2A, with penalties totaling $31,250 for various safety code violations, though this appears to be historically related to unauthorized short-term rental activity. Recent inspections and service requests indicate ongoing rodent control efforts, with bait applied consistently through early 2025, though a significant rat sighting was reported in June 2025. The building has undergone multiple inspections resulting in both passed and failed rodent inspections, particularly noting failures in July 2024 and August 2024.

Other maintenance issues include recent complaints about door/window problems, garbage storage, and various unsanitary conditions. The building's bedbug reporting history from 2019 to present shows no documented infestations or remediation efforts, suggesting proper monitoring of this particular pest issue. The property owner, John Catalic, has shown attempts to address certain violations, as evidenced by the pattern of closed complaints, though many violations remain open as of 2025.
