400 4th Avenue, Brooklyn, NY 11215

400 4th Avenue is a 4-story, 6-unit Old Law Tenement building constructed in 1931 in Gowanus, currently owned by Iftikhar Din. The property has faced recurring housing maintenance challenges, most notably regarding bedbug reporting compliance, with open violations in 2023 and 2024 related to the failure to submit annual bedbug reports as required by HPD rules. The building's safety compliance record shows several significant open violations from 2018 related to missing safety notices in common areas, including smoke detector and carbon monoxide detector requirements, as well as inadequate building registration and emergency gas leak procedures.

These violations also include a 2018 issue concerning self-closing entrance doors. More recently, in June 2025, there is an active complaint with the Department of Health and Mental Hygiene regarding spoiled food at an unspecified establishment in or near the building. The building has experienced maintenance issues in the past, including a drainage system problem noted in November 2019 that resulted in a $500 Environmental Control Board violation, though this appears to be an active status rather than currently due.

Historical records from 2010-2012 show instances of rodent activity, though the building passed subsequent inspections. There have been three 311 service requests (all closed) from 2018-2022 regarding various building issues, including work without a permit, construction enforcement, and drainage concerns. The most recent bedbug report in 2022 indicated no units were infested, though it's worth noting that the reporting period covers the years 2020-2021 when no infestations were reported, and there have been recurring violations related to the annual reporting requirement.
