640 Warren Street, Brooklyn, NY 11217

640 Warren Street is a 4-story, 8-unit Old Law Tenement building located in Park Slope and built in 1920, currently owned by Sam Brown. The building has experienced recurring rodent-related issues over the past several years, with the most recent rat activity noted in January 2023, followed by a successful compliance inspection in March 2023.

Multiple 311 complaints regarding plumbing and water supply issues were filed in February 2022, with investigations conducted showing the complaints were related to a building-wide condition, though no violations were ultimately issued. Earlier records show similar concerns, with rat activity reported in 2022 (November) and 2021 (June), and bait application in November 2022.

Throughout the past five years, 640 Warren Street has maintained a record of being pest-free with respect to bedbugs, as evidenced by consistent reports filed annually between 2019 and 2024 showing zero infested dwelling units or eradication cases. The building has passed several inspections since 2018, indicating some level of effective management regarding pest control, though the recurring nature of the rodent complaints and inspections suggests this remains an ongoing challenge. The most recent building inspection records (2023) indicate improved conditions, with the last recorded rat activity being more than two years ago.
