Augrented Insights Report for 4307 12th Avenue

4307 12th Avenue is a four-story, 16-unit residential building in Borough Park, constructed in 1916, and currently owned by Aron Gumbu. The property has experienced recurring heat and hot water issues over the past 2.5 years, with three building-wide and two apartment-specific complaints in Winter 2024-2025 alone, all of which were resolved with confirmation of restored services. Notable maintenance concerns have included multiple violations issued in late 2024, particularly affecting apartments C4 and A2, including problems with smoke detector functionality, carbon monoxide detectors, and roach infestations.

Additional issues were documented regarding plumbing fixtures, including a bathtub/shower complaint in May 2024, refrigerator problems in October 2024, and a broken window guard in April 2024. The building's heating system has been a particular focus of regulatory scrutiny, with three active violations for failure to file external low-pressure inspections from 2023-2024. A Department of Buildings investigation in October 2023 identified an unregistered boiler situation in apartment D1, leading to a $625 penalty.

There have been two significant safety-related complaints in 2024 regarding lead dust and construction work, though these remain in progress. The building has maintained a clean record regarding bedbug infestations, with all six annual reports since 2020 showing zero cases of infestation, eradication, or re-infestation. The property has also experienced periodic issues with building access systems, as evidenced by a November 2023 complaint regarding the bell/buzzer/intercom system.
