Augrented Insights Report for 302 Knickerbocker Avenue

302 Knickerbocker Avenue is a three-story, four-unit Old Law Tenement building in Bushwick, constructed in 1931 and currently owned by Yong Hyun. The building has experienced several maintenance issues over the past five years, with the most recent situation involving an open violation from May 2024 regarding an unauthorized partition installation in apartment 2R. During the same May 2024 inspection, multiple safety and maintenance violations were documented and subsequently closed, including issues with windows, doors, and fire retardant materials in the public areas.

The building has a history of unsanitary conditions, particularly in 2019, when complaints about mold, pests, and various maintenance issues were recorded. Window safety concerns have also been noted, with a broken window guard complaint in 2020, though no violations were ultimately issued. The property has undergone regular bedbug inspections from 2020 through 2025, consistently reporting zero infested or re-infested units, indicating effective pest management.

However, recent rodent activity has been noted, with inspections in 2024 showing rat activity, though a compliance inspection in April 2025 passed without issues. The building's maintenance history includes various repairs and violations related to safety features such as door latches and window sashes, particularly in May 2024 when multiple violations were documented and resolved. The Department of Buildings conducted a storefront sign inspection in 2021, which resulted in no violations being warranted. The property has remained actively maintained, with regular inspections and prompt attention to violations, though some concerns about building safety features and unauthorized modifications persist as of the most recent inspection records.
