9727 3rd Avenue, Brooklyn, NY 11209
The 14-unit, 4-story residential building at 9727 3rd Avenue in Fort Hamilton, owned by Vincent Iannelli, has experienced several recurring maintenance issues over recent years, particularly relating to heating systems and safety equipment. Most notably, there have been multiple heating system complaints in 2024-2025, with the most recent related to a radiator issue reported in March 2025.
The building has also faced electrical system challenges, including wiring and outlet problems reported in March 2025, which HPD was unable to inspect despite being classified as emergencies. Additional concerns have included sanitary issues such as garbage storage violations (September 2024) and two apartments (B3 and C2) facing multiple violations in late 2024 regarding defective smoke and carbon monoxide detectors, as well as various maintenance issues including window frame problems and cabinet concerns. The building's inspection history reveals some significant safety concerns, particularly in 2018, when violations were issued regarding blocked exit passageways and a failure to provide unobstructed fire escape access, resulting in Environmental Control Board penalties.
There were also past concerns about illegal commercial use and unauthorized signage, though these were resolved with no violations found upon inspection. Importantly, the building has maintained a clean record regarding bedbug infestations, with consistent reporting of zero infested units across all reported years from 2019 through 2025. The property, built in 1926, has been subject to regular city inspections and monitoring, with violations generally being addressed though some open violations from late 2024 remain pending follow-up inspections.
