637 Warren Street is a three-story, three-unit residential building located in Park Slope, built in 1899 and classified as an OLD LAW TENEMENT, currently owned by Sally Smith. The building has experienced recurring Housing Maintenance Code violations related to annual bedbug reporting requirements over the past three years, with open violations recorded in 2022, 2023, and most recently in April 2024. Despite these documentation issues, the property has maintained a clean record regarding actual bedbug infestations, as evidenced by the 2021 bedbug report showing zero infested, eradicated, or re-infested units for the period between November 2019 and October 2020.
The building's pest management history includes a rat sighting complaint in August 2021, which was investigated by the Department of Health and Mental Hygiene and resulted in no violations being found. Additionally, rodent inspections conducted in both September 2021 and February 2018 passed without any issues. In terms of improvements or modifications, a permit was issued in August 2020 for exterior work (Job Number: 340749505), though specific details of the work completed under this permit are not provided in the available data. The most significant ongoing concern for the building appears to be the pattern of open violations related to bedbug reporting requirements, which have persisted despite the absence of actual bedbug infestations on record.
