4520 12th Avenue is a 6-story, 48-unit residential building located in Borough Park and owned by Yakov Gelb. The building, constructed in 1940, has experienced several recurring maintenance issues in recent years, with the most significant concerns centering around fire safety and elevator reliability. In May 2025, multiple complaints were registered regarding fire escapes and unsanitary conditions, with violations issued that required the owner to correct these conditions.

The building has also faced ongoing elevator-related challenges, with multiple complaints about the single device service during 2023-2024, though most inspections found no violations at the time. A significant set of violations was documented in December 2024 for apartment A3, including missing smoke detectors, carbon monoxide detectors, and a non-compliant door, though these were certified as corrected by January 2025. The property's maintenance history shows a pattern of issues requiring attention, including water leaks, plumbing problems, and various unsanitary conditions such as mold and pest infestations.

Of note, there have been no reported bedbug infestations in the past three years (2023-2025), and the building has consistently passed rodent inspections in 2017, 2019, and 2020. Recent violations and complaints indicate ongoing maintenance challenges, with particular attention needed to address fire safety compliance and building systems reliability. The property has maintained compliance with bedbug reporting requirements, showing no infestations or eradication efforts needed in recent years.
