438 49th Street, Brooklyn, NY 11220
The 32-unit, 4-story residential building at 438 49th Street in Sunset Park, owned by Jennifer Lau, has experienced multiple recurring maintenance issues in recent years, most notably regarding pest control and safety systems. In June 2025 alone, the building received multiple violations across various categories including rodent problems, flooring issues, wall conditions (paint/plaster), and unsanitary conditions.
More concerning are the safety-related violations during this period, including issues with smoke detectors and carbon monoxide detectors that were classified as emergencies. The building has a documented history of pest management challenges, as evidenced by multiple unsanitary condition complaints regarding pests in 2024 and 2025, as well as three consecutive rodent inspections (December 2023, February 2024, and July 2025) showing rat activity.
Earlier violations from 2024 highlight significant concerns including a lack of heating/hot water access in December 2024 (when inspectors were unable to gain access), mold issues in apartment 2C, and multiple safety violations in apartment 2D including missing carbon monoxide and smoke detectors. The building's maintenance history shows some attention to various issues, with many violations being closed after inspection, but there remain several persistent problems that have been documented over multiple years. The property has demonstrated compliance with bedbug reporting requirements, showing no infestation cases since 2023, and there were two historical instances of bedbug issues (one in 2022-2023 and another in 2021-2022) that were reportedly addressed.
