645 Warren Street, Brooklyn, NY 11217

645 Warren Street is a three-story, three-unit residential building located in Park Slope, Brooklyn, and constructed in 1901 under the Old Law Tenement classification. The building has experienced several concerning pest-related issues in recent years, with multiple rodent sightings documented between July and August 2021, including both mouse and rat sightings.

While the DOHMH conducted inspections in response to these complaints, only one inspection resulted in violations requiring follow-up inspections. More significantly, the building currently has three open Class A Housing Maintenance Code violations from 2022 to 2024 related to the failure to file annual bedbug reports as required by HPD rules, though it should be noted that the building's bedbug reporting for the period of November 2019 to October 2020 showed no infested units, no units requiring eradication, and no re-infestation.

The property's rodent inspection history shows mixed results, with rat activity being detected during the December 2021 inspection, though earlier inspections in 2018 and July 2021 passed without incident. The current owner, Neil Donahue, has been responsible for the property during this period of recurring pest-related issues, with the most recent bedbug reporting violations still remaining open as of April 2024. While the building has passed some inspections and shown no bedbug infestation in its most recent reporting period, the combination of open violations and documented rodent sightings suggests ongoing challenges with maintaining compliance across various health and safety requirements.
