902 43rd Street, Brooklyn, NY 11219
902 43rd Street is a 4-story, 44-unit New Law Tenement building constructed in 1925 and currently owned by Jack Rosenwaser. The property has experienced recurring issues with indoor air quality, particularly chemical vapors and odors, with multiple complaints filed between January 2025 and May 2025. The building has also faced significant heat and hot water system problems, with emergency complaints recorded through HPD in February 2025 indicating building-wide and apartment-specific failures.
Recent maintenance issues have included a sewage leak in December 2023, along with various housing code violations. The building has been subject to multiple pest control challenges, with documented bedbug infestations in apartments 1D and 4C, and ongoing rodent issues noted in inspection records. Apartment 4C in particular has multiple open violations as of January 2024, including problems with window guards, floor tiles, and various repair needs.
The Department of Buildings has issued two active violations related to energy efficiency documentation in 2023-2024. Historical data shows a pattern of maintenance and infestation issues, with the most recent bedbug report from December 2024 showing one unit required treatment. While some past violations have been resolved, including those related to safety and sanitation, the persistence of recent complaints suggests ongoing challenges with building systems and maintenance.
