773 4th Avenue, Brooklyn, NY 11232

The 773 4th Avenue building in Sunset Park is an 8-unit, 4-story old law tenement constructed in 1960, currently owned by Jacob Zimmer. The building has experienced recurring maintenance issues throughout recent years, with the most recent complaint in January 2025 regarding heat and hot water problems affecting the entire building.

Significant issues were documented in August 2024, including multiple reports of water leaks with heavy flow, mold (unsanitary conditions), ceiling paint/plaster problems, plumbing issues, and safety concerns regarding carbon monoxide detectors. These complaints resulted in several Housing Maintenance Code violations, particularly affecting apartment 2L, which had issues with its smoke detector, hot water temperature, vinyl tile floor, and other safety concerns that were addressed by December 2024. The building's history shows persistent access issues during inspections, as evidenced by multiple "Inspector Unable To Gain Access" dispositions for complaints related to plumbing, electrical, and gas concerns between 2019 and 2024.

In late 2024, several violations were issued following an October inspection, including problems with fire retardant materials in the 3rd-story public hall, hot water temperature in 2R, and various maintenance issues in 2L, though most were subsequently certified as corrected. The Department of Buildings records show multiple violations for failure to file external low-pressure inspections between 2018 and 2022, though these were ultimately dismissed. Recent pest control efforts indicate both rodent activity and bedbug cases in the building, with the most recent rodent inspections in 2025 showing continued pest presence and prior bedbug infestations reported in 2023 and 2022.
