450 6th Avenue, Brooklyn, NY 11215
The 450 6th Avenue building, a 3-story, 4-unit residential tenement built in 1920 in the South Slope neighborhood, has experienced several compliance issues in recent years.
Most notably, the building was cited for failure to file annual bedbug reports in 2021, 2022, and 2023, though a subsequent report filed in March 2024 covering the period from November 2022 to October 2023 showed no confirmed infestations. Between 2020-2024, the property faced multiple Environmental Control Board violations related to building safety systems, including issues with a missing backflow preventer, fire dampers, emergency fuel cut-off switch, and concerns about boiler room safety and storage violations, with one active violation from 2024 carrying a $6,250 penalty.
The building also had administrative violations for failing to file 2021 and 2022 external low pressure inspections in 2023, though these were ultimately dismissed. A recent Local Law 188/17 compliance inspection in February 2024 found no violations, and the property maintained a passing rodent inspection record in 2010 and 2019, suggesting reasonable pest control measures are in place.
