858 42nd Street, Brooklyn, NY 11232

The two-story New Law tenement building at 858 42nd Street in Borough Park, owned by Qiyuan Chen, has experienced several significant maintenance issues, particularly during 2018-2019. The most pressing concern during this period was a recurring mold problem, with multiple complaints filed between March and April 2019, one of which led to a Housing Maintenance Code violation in April 2019 specifically citing mold conditions in Apartment 2R. This unit also had several other violations that year, including issues with paint quality, missing smoke and carbon monoxide detectors, and inadequate gas supply to the stove, all of which were resolved by mid-2019.

The building faced heat and hot water issues in December 2018, though inspectors were unable to gain access to verify the conditions. More recently, the building has shown improvement in maintenance and reporting compliance. As of 2025, the building has submitted four consecutive bedbug reports (2021-2025) showing zero infestation cases during the reporting periods.

Two Department of Buildings complaints from 2022 regarding illegal conversion and work without permits were recorded, but both were closed due to inspectors being unable to gain access during final attempts. Additionally, there are two Housing Maintenance Code violations from 2022-2023 related to annual bedbug reporting requirements, though these appear to have been resolved based on the current filings. The building's most recent bedbug report filing in May 2025 indicates no current issues, with the property maintaining an active record of reporting compliance for the past two years, though the reports cover periods from November 2023 to October 2024.
