Augrented Insights Report for 646 Amsterdam Avenue

646 Amsterdam Avenue is a 5-story, 13-unit residential building located in Manhattan's Upper West Side, owned by Joan Cohen and constructed in 1920 as a New Law tenement. The building has maintained a strong record of bedbug prevention, with all interior inspections from 2019 through 2025 consistently showing zero infested or eradicated units, and no reports of any infestations filed during this period.

Regular rodent inspections have also been conducted annually from 2018 through 2025, with the most recent inspections in 2024 and 2025 showing passed results, though a recent 311 complaint regarding food establishment violations related to pests and sanitation (filed June 2025, currently in progress) may require monitoring. The building's maintenance history shows generally positive compliance with city regulations, though there was a notable Housing Maintenance Code violation in 2021 regarding the failure to file an annual bedbug report, which has since been resolved. Four bedbug reporting periods from 2019 to 2024 show consistent zero infestation counts.

Recent food establishment issues were documented in 2022-2024 regarding permit violations, though these were administratively closed. The property has also undergone standard permit processes, with records showing permits issued in 2019 and 2020 for unspecified work. An audit of professional certification compliance in 2019 found no violations warranting inspection.
