312 West 89th Street, Manhattan, NY 10024

312 West 89th Street is a four-story, 20-unit residential building located in Manhattan's Upper West Side, owned by Magdalena Kos. The 1890 property has experienced recurring heating and pest management issues over the past several years that warrant attention. Most notably, there have been multiple incidents of heat and hot water outages between 2020 and 2023, with the most recent emergency complaint regarding a smoke detector issue in late 2023/early 2024 showing HPD's inability to gain access for inspection.

The building has faced persistent rodent challenges, with multiple rat sightings documented between 2021 and 2022, though recent inspections in 2025 show improved compliance with passed inspections and bait applications. While the building has maintained a clean record regarding bedbug infestations in the past three years, three open violations from a November 2021 inspection remain active, related to proper signage requirements for carbon monoxide detection, heating system access, and gas leak procedures. Recent developments indicate some improvements in building maintenance, with 2025 rodent inspections showing passed compliance.

The most concerning pattern has been the intermittent heating issues, as evidenced by multiple emergency complaints and service requests over the years. The building's maintenance history reveals a combination of emergency situations requiring immediate attention (primarily heat-related and safety concerns) and ongoing pest management efforts, particularly during 2022 when multiple bait applications were executed. The property has demonstrated some responsiveness to regulatory requirements, as evidenced by recent rodent inspection compliance, though the persistence of certain open violations from 2021 suggests ongoing monitoring is necessary to ensure full compliance with housing maintenance codes.
