857 Halsey Street, Brooklyn, NY 11233

857 Halsey Street is a 6-unit, 3-story old law tenement building located in Bedford-Stuyvesant and built in 1910, currently owned by Abe Stein. The property has experienced recurring heating system issues, with multiple complaints about lack of heat and hot water in 2022-2024, though in most cases heat and hot water were restored before inspections could be completed.

The building faces several significant maintenance and safety concerns, as evidenced by recent housing maintenance code complaints and violations from April 2025, including issues with doors/windows, carbon monoxide detectors, water supply problems, mold, and pest infestations. The Department of Buildings has active violations regarding failure to file required external low-pressure inspections from 2018-2023, as well as historical concerns about the boiler system. The building underwent a change of ownership to Halsey Estates, LLC in 2020, during which period multiple environmental control board violations were issued related to building maintenance, including problems with walls, bricks, and stucco.

The property has shown recent pest control efforts, with rodent inspections in 2022 (passed), 2024 (passed), and 2025 (failed for other reasons). While there have been serious violations in the past, particularly regarding reoccupying units under repair orders and various maintenance issues, many of these violations have been closed through appropriate corrective actions, though some recent violations remain active. The building's heating system remains a recurring concern, with multiple complaints about insufficient heat and hot water between 2022 and 2024, despite temporary resolutions noted in most cases.
