639 Foster Avenue, Brooklyn, NY 11230

639 Foster Avenue is a 6-story, 22-unit residential building in Kensington, constructed in 2019 and currently owned by Solomon Feder. The building has experienced persistent moisture-related issues, particularly mold, with eight documented complaints between 2022 and 2025, including at least one instance (July 2023) that resulted in the issuance of violations.

Other maintenance concerns have included water supply issues (June 2022), heat and hot water problems affecting the entire building (June 2022), stairway safety issues (March 2023), and a violation related to bathroom plaster surfaces in Apartment 403 (2024). The building underwent construction between 2018-2021, during which there were several Department of Buildings Environmental Control Board violations related to safety and compliance issues, including improper window protection and scaffold safety concerns, though these were all resolved with penalties paid. The property has demonstrated effective pest control management, with no reported bedbug infestations in the past five years (2019-2024) and passed rodent inspections in August 2023.

The building's maintenance record shows various housing code violations over the years, though many have been resolved. Most recent complaints regarding unsanitary conditions (mold) have been documented in 2025 (April) and 2024 (February), with the 2025 complaint noting that HPD was unable to complete their inspection. The building's response to emergencies and maintenance issues has generally followed appropriate procedures, though the persistence of mold issues suggests ongoing moisture management challenges within the structure.
