AI summary · updated June 2026

25 West 9th Street is a four-story, six-unit residential building in Greenwich Village, constructed in 1855 and currently owned by Richard Korchak. The building has experienced some maintenance challenges over the past several years, though recent data shows improvement. Notably, there were two Housing Maintenance Code violations in 2021 and 2023 regarding the failure to file annual bedbug reports, though these violations have since been marked as closed. A gas utility complaint was filed in August 2021, which was investigated in January 2022 with no violation found.

The most significant concern during the building's recent history has been rodent activity. In 2022, there were two inspections (January and February) that documented rat activity, though subsequent inspections in 2022 (August), 2023 (May), and 2024 (August) all passed without violations. The building's bedbug management appears to be under control, with the most recent three annual reports (2022-2023, 2023-2024, and 2024-2025) showing zero infested or re-infested units, and all previous bedbug reports from 2020-2021 showing similar results. The property has demonstrated compliance with rodent control measures in recent years, passing all inspections from 2019 through 2024, with the exception of the two violations noted in 2022. While the building showed some maintenance issues in previous years, the current data suggests improved management of both bedbug reporting requirements and pest control measures.
