AI summary · updated June 2026

The three-story, three-unit residential building at 663 East 21st Street in Flatbush, owned by Absarul Mowla and constructed in 1970, has experienced several concerning issues over recent years. Most notably, there are ongoing bedbug reporting violations, with the Department of Housing Preservation and Development (HPD) issuing citations in 2022, 2023, and 2024 for failure to file the required annual bedbug reports. The building has also faced multiple heating-related problems, including a significant heat/hot water complaint in November 2021 that resulted in violations being issued. Several heating system-related violations remain open, including issues with a locked cellar door access and missing heating system key notice.

The property has been subject to rodent activity, with inspections in late 2023 and early 2024 confirming rat activity, though bait was applied in November 2023. Environmental Control Board violations were recorded in January 2021 regarding a lack of required green space in the front yard, which was reportedly covered in concrete, though this violation was resolved without any penalty. The Department of Buildings has recorded several complaints, including one in 2024 about work without a permit, though access was denied for inspection. While the building has maintained some compliance with bedbug reporting in the 2020-2021 period, with no reported infestations during that specific filing period, the recurring nature of code violations and the presence of rodent activity suggest ongoing maintenance challenges.
