4420 10th Avenue, Brooklyn, NY 11219

The three-story, five-unit residential building at 4420 10th Avenue in Borough Park, owned by James Ostrowski, has a documented history spanning several years since its construction in 1930 as a New Law Tenement. The building's most pressing recent issue was identified in 2024, when a violation was issued for failing to file the required annual bedbug report, though this was consistent with previous violations in 2023, 2022, and 2021.

Despite these violations, the building's bedbug reporting history shows no actual infestations, with all four annual reports from 2021 through 2025 (most recent filing in May 2025) indicating zero infested units, zero eradicated units, and zero re-infested units. The building underwent various safety inspections and corrections between 2019 and 2022, including a significant cluster of violations in 2019 related to window guards and door self-closing mechanisms, particularly in apartment 1B and throughout public areas.

These included missing or defective window guards in apartment 1B and the public hall, along with other safety-related issues such as the need to discard three radiators from the first-story public hall area. More recent inspections have generally shown compliance, including a passed rodent inspection in May 2022 following a reported rat sighting earlier that month, for which the Department of Health and Mental Hygiene found no violations upon inspection. The most recent documented violation from 2024 regarding bedbug reporting requirements appears to be an administrative oversight rather than an indication of pest problems, given the building's consistent recent history of maintaining a pest-free status across multiple reporting periods.
