Augrented Insights Report for 1974 51st Street

The 47-unit, 4-story New Law Tenement building at 1974 51st Street in Borough Park, owned by Joseph Mendelowits, has experienced several significant maintenance issues in recent years, with the most urgent concerns centering around heating and hot water systems. The building has faced consistent heat and hot water problems throughout 2025, with multiple emergency complaints registered from January through March, though most were closed after temporary restoration of services was confirmed.

More recently, in April 2025, multiple complaints regarding flooring conditions were documented, along with unsanitary mold issues, though inspections found some of these did not violate housing laws, while others resulted in violations requiring correction. The building has also encountered rodent issues, with failed inspections recorded in both April and May 2025, following a rat sighting complaint in March 2025. The property has a concerning history of fire escape maintenance issues, with violations documented in December 2024 regarding defective drop ladders requiring replacement and adjustment.

Between 2020 and 2022, the building accumulated several violations related to energy benchmarking and reporting, including failures to file required documentation and display energy efficiency scores, though some of these violations were later dismissed. While the building has experienced one documented bedbug infestation in 2022-2023 (involving one unit), subsequent annual filings (2023-2024 and 2024-2025) show no further infestations. Recent housing maintenance inspections in 2024 identified various interior maintenance issues in Apartment 3C, including problems with bathroom fixtures, kitchen cabinets, and smoke detector functionality, though most of these violations were certified as corrected by early 2025.
