480 Warren Street, Brooklyn, NY 11217

480 Warren Street is a three-story, four-unit residential tenement building constructed in 1925, currently owned by David Cohen in the Gowanus neighborhood. The property has experienced persistent water issues, with three separate water leak complaints filed between November 2023 and January 2024, including one classified as an emergency due to heavy flow, though only one of these prompted an HPD inspection resulting in no violations. More recently, as of April 2024, there is an open Class A violation regarding damaged plaster and paint in a ceiling of Apartment 2.

The building has maintained a clean record regarding bedbug infestations, with all recent annual reports from 2021 through 2025 showing zero cases of infestation, eradication, or re-infestation. The property underwent some construction work in 2022-2023, which revealed several compliance issues. An Environmental Control Board violation was recorded in January 2023 for combustible debris accumulation during construction, and another violation from May 2022 noted failure to provide inspection access to construction work.

While these violations were ultimately resolved, they indicate periods of construction-related disruption. The building has a generally poor access record for inspections related to the recent water leak complaints, with inspectors unable to gain access on two occasions. Heritage reporting shows regular compliance with City requirements, though there was a period in 2023-2024 requiring two reminders for bedbug reporting compliance. Despite the water issues and open violation, the building's overall record shows no recent instances of pest infestations and consistency in annual bedbug reporting compliance since 2020.
