Augrented Insights Report for 1020 45th Street

1020 45th Street is a 4-story, 32-unit residential building constructed in 1921 in Borough Park, currently owned by Louis Koplowitz. The property has experienced recurring maintenance issues in recent years, with the most significant concerns emerging in 2024-2025. Current violations from 2024 include lead paint hazards, pest infestations (including mice and roaches), and missing window guards in apartment 3D, along with multiple plumbing issues.

The building has shown persistent plumbing problems, with four complaints regarding basins/sinks between 2024-2025, three of which resulted in violations. Other notable issues include water leaks, wall paint/plaster problems, and rodent sightings, with inspections confirming rat activity in 2025. The building's recent history shows recurring problems with both sanitation and structural maintenance.

In late 2024, there were multiple violations related to pest infestations, mold, and door issues in apartments 3F and 3A, as well as concerns about the heating system access. Historical complaints dating back to 2019-2022 include issues with building stability, debris, and work being conducted without permits, though these complaints were ultimately closed without confirmed violations. The property has maintained a clean record regarding bedbug infestations, with all annual reports from 2019-2024 showing zero infested units. While some violations have been resolved, including a 2019 ECB violation regarding stairwell windows and exterior walls, the building continues to have open violations as of 2025, particularly regarding lead paint and window guard requirements.
