6521 20th Avenue, Brooklyn, NY 11204
The three-story, 4-unit residential building at 6521 20th Avenue in Bensonhurst, owned by Tony Tang, has experienced a series of maintenance issues throughout 2024, with the most recent incidents occurring in June 2024 involving window frame and electric/gas range problems. Significant issues were documented in May 2024, including water leaks (both damp spots and slow leaks), unsanitary conditions with pest infestations, and problems with doors and windows.
The building is currently classified as a "HEREAFTER CONVERTED CLASS A" structure and has been subject to multiple Housing Maintenance Code violations, including electrical wiring issues, door problems, and maintenance deficiencies in apartment 2F, which experienced pest infestations (mice and roaches) that required remediation. Recent violations from July 2024 also noted issues with ceiling maintenance and historical plaster problems in public areas. The building has a documented history of permit violations from 2018 regarding unpermitted sign installation on the front facade, though this was resolved with no penalties.
Importantly, there have been no bedbug infestations reported in any of the annual filings from 2021 through 2025, suggesting effective pest management in this regard. The most recent 311 service requests indicate that while some complaints resulted in violations being issued (e.g., water leaks and pest issues in May 2024), many others were inspected and closed without violations being noted. The property has maintained a consistent pattern of 311 complaints and housing maintenance code inquiries, particularly around doors, windows, and various maintenance issues, with the most frequent problems appearing to relate to pests, water, and appliance systems.
