Augrented Insights Report for 424 6th Avenue

The four-story, 12-unit residential building at 424 6th Avenue in Park Slope, owned by Christopher Judd, has experienced several concerning issues over recent years, particularly in health and safety compliance. Most notably, as of February 2024, Apartment 2 is facing multiple open violations including problems with self-closing doors, missing carbon monoxide detectors, a non-functioning smoke detector, inadequate heat supply, and the absence of bedbug reporting documentation - all of which are significant safety and habitability concerns.

The building has also had recurrent problems with garbage and recycling storage in 2023, though no violations were found in these cases. The property has a documented history of heating system issues, with a heat/hot water emergency complaint filed in February 2024, violations related to heating and boiler systems in 2022, and an open violation for inadequate heat supply affecting Apartment 2 as of February 2024.

A notable safety concern was addressed in February 2024 regarding a door device preventing self-closing functionality at the building entrance. While the building passed rodent inspections in 2016 following initial rat activity reports, and had certain violations resolved (including one related to heating system signage in 2022), the persistence of recent open violations, particularly those affecting basic safety systems, indicates pressing maintenance needs.
