609 West 186th Street, Manhattan, NY 10033

609 West 186th Street is a 5-story, 26-unit residential building constructed in 1915, currently owned by Kenneth Diamondstone. The property has experienced recurring heating and hot water issues, particularly during October 2023, when multiple complaints were filed regarding both building-wide and apartment-specific problems. Ten separate heat/hot water complaints were filed between October 9-24, 2023, with several requiring emergency responses.

A similar heating complaint was logged in December 2024, though inspectors were unable to gain access for verification. The building has also faced rodent issues, with the most recent complaint in May 2025 resulting in an inaccessible inspection, following a pattern of rodent activity noted in October 2024 and another inspection failure in December 2023. Significant maintenance concerns have emerged from inspections in November 2023, particularly in Apartment 21, which showed multiple open violations including lead paint hazards, a mouse infestation, broken glass issues, and problems with water temperature and flooring.

The building's recent history includes three successful rodent inspections (2025, 2024, and 2022), though a rat activity report was noted in late 2024. While the building experienced bedbug infestations in 2022 (two units affected), subsequent annual reports in 2023, 2024, and 2025 show zero cases. The property's heating system was previously inspected in 2020, with no violations found, though this was several years before the recent heating complaints.
