1123 Avenue K, Brooklyn, NY 11230
1123 Avenue K is a 6-story, 54-unit New Law Tenement building built in 1929 and currently owned by David Nierenberg. The building has experienced recurring issues with heating systems, as evidenced by multiple heat/hot water complaints in early 2025, including a building-wide emergency complaint in March 2025. These recent complaints follow similar heat-related issues from February 2025 and indicate a persistent problem with building-wide heating infrastructure.
The building has also faced significant maintenance challenges in recent years, including multiple 2024 complaints about unsanitary conditions, with violations issued for pests, and problems with garbage/recycling storage. Of particular concern was an undated water leak issue that received emergency attention in 2024. The property has a history of safety compliance issues, particularly regarding life safety systems.
In August 2024, violations were issued in apartment F7 related to non-functional smoke and carbon monoxide detectors, and there were multiple 2020 violations concerning elevator door monitoring systems that were ultimately resolved. The building underwent several Department of Buildings inspections in 2020-2021, with one gas utility violation resulting in a penalty, though most complaints during this period were found to have no violations warranting penalties. Historical records show consistent passing rates on rodent inspections from 2010 through 2023, and there have been no reported bedbug infestations in the past five years. The building's management has generally addressed violations when cited, with most being marked as closed, though there are currently open violation statuses for certain conditions in apartment C2 related to pests and maintenance issues as of 2024.
