Augrented Insights Report for 234 Union Avenue

234 Union Avenue, a six-story New Law Tenement building constructed in 1930, currently owned by Howard Trachtenberg, has shown concerning maintenance patterns in recent months. The building has multiple open Housing Maintenance Code violations as of 2024-2025, notably including issues with apartment 17's pest infestation, defective smoke and carbon monoxide detectors, and door problems. Recent inspection records from 2025 show the HPD attempted to investigate multiple complaints regarding electrical issues, door/wind window problems, intercom system failures, and pest infestations, but were unable to gain access to conduct inspections.

These complaints, filed in June 2025, were subsequently closed due to lack of access for inspection. The building's history reveals a pattern of maintenance challenges, with significant pest control issues documented through annual bedbug reporting showing infestations in multiple units between 2021-2023. Rodent inspections between 2022-2024 indicate variable results, including periods of rat activity and the application of bait.

Previous Housing Maintenance Code violations in apartment 9 were addressed between 2024-2025, involving repairs to doors, flooring, and plastered surfaces. The property has also accrued certain violations related to energy efficiency documentation in 2021, though these were ultimately dismissed. A food poisoning complaint is currently in progress as of May 2025, and there are persistent concerns about building systems, including a 2025 smoke detector issue noted by HPD that remains unresolved pending access for inspection.
