Augrented Insights Report for 401 East 23rd Street

401 East 23rd Street is a 4-story, 23-unit New Law Tenement building constructed in 1925 in the Flatbush neighborhood, currently owned by Sam Klein. The building has experienced recurring maintenance issues in recent years, particularly in 2025, with multiple complaints related to heat and hot water outages, unsanitary conditions including pest infestations, and water damage. In January 2025, there was a notable series of complaints regarding heat and hot water problems, with both apartment-specific and building-wide reports, though inspections indicated restoration of services. More recently, in June 2025, there were reports of water leaks and pest issues resulting in Housing Maintenance Code violations.

The building has a documented history of various maintenance violations that have been addressed over time. Significant issues identified in 2023-2024 included problems with carbon monoxide detectors, pest infestations (including rats and roaches), and building systems including heat and hot water. Recent inspections from July 2025 confirmed ongoing rat activity, continuing a concerning pattern from previous inspections. The property has also shown some improvement in bedbug management, with only one reported case in the 2023-2024 filing period, representing a decrease from previous years when multiple units were affected.

The building's maintenance record shows a mix of resolved and ongoing issues, with recent violations including unsanitary conditions, water leaks, and various safety-related maintenance needs. While many historical violations have been closed and addressed, the recurrence of heat/hot water complaints and pest problems suggests continuing challenges with building maintenance and resident comfort. Recent violations include pest control issues (June 2025), water damage (June 2025), and a ceiling paint/plaster issue (June 2025). The building's history also shows attention to safety systems, with violations related to carbon monoxide detectors, fire retardant materials, and self-closing doors being addressed through inspections and repairs.
