6813 21st Avenue, Brooklyn, NY 11204

6813 21st Avenue is a 42-unit, 4-story residential building built in 1926 and currently owned by Mark Polanski. The property has experienced several significant maintenance issues in recent years, with the most concerning being multiple water supply problems and cooking gas issues reported between late 2023 and early 2024. In total, there were four separate water supply complaints in January 2024, with some being classified as emergencies, though HPD was often unable to gain access for inspection.

The building experienced heat and hot water problems in both November 2023 and May 2022, though in both cases tenants reported that the issues were resolved before inspection. Other notable concerns include a mold issue reported in November 2023, inspections revealing defective fire doors in 2024, and a 2023 violation regarding an obstructed fire escape due to an air conditioner unit. The building's maintenance history shows consistent attention to pest control, with no reported bedbug infestations in the past five years from 2019 to 2024, and successful rodent inspections in 2012 and 2019.

Recent violations indicate ongoing concerns with building safety features, particularly regarding fire safety, including issues with self-closing doors and various problems with fire retardant materials in public areas. While most HPD inspections have resulted in no violations being issued, the frequency of complaints, particularly regarding essential services like water and heat, suggests some challenges in maintaining consistent building systems. The building's age and history as a New Law Tenement are reflected in its varied maintenance needs, though the complete lack of reported bedbug infestations in recent filings is notable.
