731 Flatbush Avenue, Brooklyn, NY 11226

731 Flatbush Avenue is a three-story, two-family residential building constructed in 1930 in the Prospect-Lefferts Gardens neighborhood, currently owned by Jackson Hoo. The property has experienced recurring heat and hot water issues, particularly during 2020, when multiple complaints were filed between April and December regarding building-wide temperature problems, despite HPD's frequent inability to gain access for inspection.

The building underwent significant renovations in 2023-2024, with records showing multiple permit applications and work being conducted on all levels, including new floor/ceiling joists, electrical and plumbing systems, for which a violation was issued in April 2023 with a penalty of $2,530 related to an observed full gut renovation in progress. The property has also faced various maintenance challenges, including pest control issues in late 2019 (roaches and mice infestations), multiple housing maintenance code violations in early 2020 regarding inadequate heat and hot water supply, and several apartment-specific issues requiring repair, such as ventilation problems, door repairs, and bathroom fixture maintenance. Recent complaints as of 2025 suggest ongoing concerns, including an active illegal conversion complaint and previous investigations into work without a permit and construction contrary to approved plans in 2023, though these were ultimately found to have no violations warranting penalties.

A 2024 violation regarding failure to file the 2023 external low pressure inspection is currently active. The building's sprawling history of complaints and violations, particularly during 2020 and in relation to heating and hot water systems, indicates recurring maintenance challenges, though many older violations have been closed. The most recent complaint in March 2025 involved ventilation issues related to a food establishment, which was subsequently closed following a Health Department inspection.
