257 Patchen Avenue is a three-story, four-unit residential building located in Bedford-Stuyvesant, Brooklyn, and was built in 1910. The property, currently owned by Joseph Ostrelcher, has undergone a class conversion to a Class A building status. The building has experienced several maintenance issues over the past five years, with the most recent being a heat and hot water complaint in January 2024 affecting the entire building, which was investigated by HPD; while no violations were issued, the inspector noted that heat was not required at the time of the inspection. This complaint marks a concerning pattern, as there was previously a building-wide heat and hot water issue reported in 2024. The building has faced some pest-related challenges, with a rat sighting reported in May 2020 leading to documented violations by the Department of Health and Mental Hygiene, though regular rodent inspections since then (most recently in June 2025) have consistently passed. Notably, there were two Housing Maintenance Code violations in 2021 and 2022 regarding the failure to file annual bedbug reports, though subsequent filings from 2022-2024 show zero infested units and no eradication or re-infestation cases. The property has maintained good compliance with bedbug reporting requirements since these violations were issued, with the most recent filings indicating no infestation issues. The building currently shows no open violations or ongoing pest problems, though the recurring heat and hot water issues remain a notable concern for resident comfort.
