4905 4th Avenue, Brooklyn, NY 11220

4905 4th Avenue is a 4-unit, 3-story brick building constructed in 1931, currently owned by Jack Cheng and located in the Sunset Park neighborhood. The property has experienced persistent maintenance and sanitation challenges over recent years, with the most pressing current concern being an active rodent infestation as of April 2025, with follow-up inspections confirming rat activity in June 2025. The building has undergone multiple inspections and received numerous complaints between 2022-2025, though many were found to have no violations.

In September 2023, multiple non-emergency housing maintenance code complaints were inspected, including issues with walls, ceilings, electrical outlets, plumbing, and water-related problems, none of which resulted in violations. The building has also had several safety-related issues, including a broken window guard in Apartment 2A (resolved August 2023) and missing smoke and carbon monoxide detectors in Apartment 2B (corrected April 2023). Historical data shows recurring rodent activity, with inspections spanning from 2018-2025 consistently indicating presence except for two inspections in 2018 that passed.

The property has experienced various maintenance issues requiring attention, including problems with paint/plaster surfaces, plumbing fixtures, and unsanitary conditions, particularly in Apartment 2A where multiple unresolved violations were noted in 2022 regarding walls, electrical outlets, bathtub, and other features. Notably, the building's bedbug reporting from 2021-2025 shows no recorded infestations or required treatments during the past five reporting periods, though a violation for not filing annual reports was issued in 2023 and 2024. Recent permit activity shows several plumbing-related permits being issued between 2019-2023, suggesting ongoing maintenance work, though specific details of the work completed are not provided in the records.
