1047 Avenue St John, Bronx, NY 10455
1047 Avenue St John is a 6-story, 42-unit New Law Tenement building located in Longwood and constructed in 1928, currently owned by Andrew Kleiman. The building has experienced several significant maintenance issues in 2025, including multiple plumbing and water-related problems, with three separate incidents involving toilets (most recently in June 2025), as well as complaints about water leaks and various paint/plaster issues affecting both ceilings and walls.
There were also emergency-level complaints about mold, a door issue, and heat/hot water problems in March 2025, suggesting ongoing maintenance challenges. The building's violation history shows improvements in some areas, with earlier violations from October 2024 regarding an obstructed fire escape and defective safety equipment (smoke and carbon monoxide detectors) in apartment 5F, as well as mold and various maintenance issues in apartment 4D, all of which were certified as corrected by late 2024. The property has faced recurring boiler-related complaints between 2020-2023, though most inspections did not find violations when access was granted.
While there were some failed rodent inspections between 2016-2019, most recent inspections (including all of 2020) have passed, indicating improvement in pest control. The building has maintained a clean bedbug record, with no reported cases between 2019 and 2024. The most pressing current concerns appear to be the recurring plumbing issues and interior maintenance problems, as evidenced by the multiple recent complaints and violations.
