Augrented Insights Report for 673 Liberty Avenue

The three-story, five-unit tenement building at 673 Liberty Avenue in East New York, owned by Sheldon Nimchan and built in 1905, has experienced several concerning issues in recent years. Most notably, there are multiple open violations related to fire safety, including blockages of the fire escape and drop ladder, which were documented in October 2022 with penalties totaling $31,250. The building has also faced serious safety concerns in January 2023, with violations issued for missing smoke detectors and carbon monoxide detectors in Apartment 3L, though inspections later found no violations related to sprinklers or mold.

An emergency heat/hot water issue was reported and resolved in December 2022. The property has had persistent rodent-related problems, with rat sightings reported in late 2022 and again in mid-2023, though the most recent inspection in September 2023 passed without violations. Additional ongoing concerns include two active bedbug report violations from 2023 and 2024 that have not yet been certified as resolved.

The building's maintenance history shows recurring issues with unsanitary conditions, particularly regarding garbage storage, and multiple complaints about egress problems in late 2022. While some earlier 311 complaints were resolved through inspections, such as sewage odors in October 2022 and various safety inspections in early 2023, the property has demonstrated ongoing challenges with maintaining basic safety systems and addressing pest control issues. The information presented here is based on data up to October 2023, and while some violations have been closed since then, several remain open as of the most recent inspection records.
