Augrented Insights Report for 535 East 21st Street

The 49-unit, 6-story residential building at 535 East 21st Street in Flatbush, owned by Yechiel Weinberger and constructed in 1962, has experienced significant maintenance challenges over the past year. Between January 2024 and July 2025, there were multiple complaints and violations related to heat and hot water issues, with two January 2024 complaints about lack of these services in apartment 2D.

The building has also faced persistent elevator problems, as evidenced by multiple Department of Buildings complaints regarding single device operation without alternate service between 2020 and 2024, with the most recent such complaint in May 2024 resulting in a violation. Additional infrastructure concerns include recurring plumbing issues, with several HPD complaints about bathtub/shower problems in 2025, and multiple reports of electrical issues such as non-lighting in May 2025. The property has documented rodent activity, with multiple bait applications recorded between April 2025 and July 2025, suggesting an ongoing pest control challenge.

Health-related complaints have included unsanitary conditions and mold issues, particularly affecting apartment 2D, as indicated by both HPD complaints and Housing Maintenance Code violations. The building's maintenance history shows attention to energy compliance matters, with several violations regarding failure to file required benchmarking reports and energy efficiency documentation between 2018 and 2023, though these violations have been dismissed. Recent rodent inspections and comprehensive bedbug reporting (showing no infestations in recent years) suggest some level of ongoing monitoring and maintenance, though the frequency of recent complaints indicates persistent maintenance challenges affecting resident comfort and safety.
