Augrented Insights Report for 7401 4th Avenue

7401 4th Avenue is a 6-story, 63-unit residential building in Bay Ridge, constructed in 1924 and currently owned by Mehmet Kalkan. The property has experienced recurring heat and hot water issues, with multiple emergency complaints filed between late 2021 and early 2023, affecting both individual apartments and the entire building. While some violations were eventually resolved, the building has required multiple inspections and follow-ups.

More recently, rodent activity has been a concern, with several complaints in 2023 leading to inspections that both confirmed rat activity and found no violations, though baiting was required. The building currently has several active Department of Buildings (DOB) violations from 2024-2025, including issues related to work without a permit for an unapproved ventilation system, and failure to maintain proper building ventilation. Recent inspections have addressed various elevator maintenance concerns, though some violations remain active.

The property has consistently filed Bedbug Reporting forms showing no infestations, and regular rodent inspections have been conducted with varying results. Historical violations from previous years included issues with building access to heating systems, hot water provision, and fire escape maintenance, though most of these have been resolved through proper remediation. The building's compliance history shows a pattern of addressing violations, though some recent matters remain open as of mid-2025.
