237 West 109th Street, Manhattan, NY 10025

237 West 109th Street is a 6-story, 25-unit residential building located in New York City's Upper West Side neighborhood, constructed in 1925 and currently owned by Nikolaos Leonardos. The building has experienced persistent rodent problems over recent years, with multiple inspections showing rat activity, including as recently as April 2025.

The Department of Health and Mental Hygiene (DOHMH) has documented several rodent-related complaints, with the most recent in 2023 showing conditions still requiring attention. Water leak issues were also reported in early 2023, with both slow and heavy flow leaks investigated by the Department of Housing Preservation and Development (HPD), though no violations were issued for these incidents. The building's history includes a significant construction-related incident in 2019 that resulted in a Stop Work Order, though this was fully rescinded within a few months.

While there was one violation in 2021 related to bedbug reporting requirements, records show that from 2021 through 2024, the building reported zero infested, eradicated, or re-infested dwelling units in its bedbug filings. The persistent rodent issues stand out as the most pressing concern, with multiple inspections between 2022 and 2025 consistently identifying rat activity. The building's management has taken some measures to address these issues, as evidenced by bait application in 2022, though the ongoing nature of the complaints suggests challenges in achieving long-term resolution.
