AI summary · updated June 2026

1042 45th Street is a 4-story, 32-unit residential building constructed in 1921 in Borough Park, currently owned by Louis Koplowitz. The building has experienced recurring maintenance issues in recent years, with particularly concerning problems centered around sanitation and structural maintenance. Most recently, in May 2025, multiple violations were documented, including mold, wall damage, and pest infestations, with HPD inspections resulting in violations that require corrective action by the owner. April-May 2025 also saw complaints regarding flooring issues and cabinet problems, though some of these inspections were either inconclusive or not completed.

The building's documented history reveals ongoing infrastructure challenges, including water leak issues, particularly noted during 2024 inspections that cited problems with the roof and water-related maintenance in public areas. Previous violations from 2024 included concerns about fire safety (self-closing doors) and exposed electrical wiring in public areas. Rodent inspections have shown inconsistent results, with the most recent inspection in July 2025 confirming rat activity, following a pattern of varying compliance since 2019. While the building has shown adherence to bedbug prevention protocols, with no reported infestations in recent years, the overall maintenance record suggests persistent challenges with water management, pest control, and general building upkeep. The property has also faced various Department of Buildings complaints over the years, including issues with gas hook-ups and ventilation systems, though these were typically resolved upon inspection.
