3621B Greystone Avenue, Bronx, NY 10463

This three-story, four-unit residential building located at 3621B Greystone Avenue in Fieldston was constructed in 1980 and is currently owned by Brendan Osullivan. The building has experienced recurring maintenance issues, particularly with its heating system, with multiple complaints about lack of heat and hot water in recent years.

Most notably, there have been three heat/hot water complaints in the most recent year (2024-2025) alone, with the most recent occurring in January 2025, which was classified as an emergency situation. The building has also had issues with electrical power outages, unsanitary conditions including pest problems, and water supply plumbing issues between late 2024 and early 2025. These complaints often required HPD intervention, though several inspection attempts were met with tenant access issues.

In addition to these ongoing maintenance concerns, the building has several open housing maintenance code violations from December 2021 related to safety and communication requirements, including failure to properly post notices regarding smoke detector requirements, carbon monoxide detection, and gas leak procedures, as well as not providing completed certificate of inspection visits at mailboxes. Despite these violations, the building has maintained a pest-free status according to bedbug reports filed between 2021 and 2024, with no infested units reported in the past four filing periods. The most recent bedbug reports from 2024-2025 show a consistent pattern of zero infested, eradicated, or re-infested units, suggesting effective pest management practices.
