Augrented Insights Report for 861 40th Street

The 3-story, 6-unit tenement building at 861 40th Street in Borough Park, owned by Weihua Tang and built in 1931, has experienced several maintenance issues over the past two years, with the most recent concerns emerging in late 2024. Notable ongoing problems include mold and paint/plaster issues, particularly affecting the bathroom in Apartment 1F, where recent inspections in November 2024 revealed multiple violations related to mold (15-19 square feet on various walls), peeling paint, and an ongoing roach infestation.

The building has also faced recurring heat and hot water access issues in 2024 (most recently reported in October 2024), though inspectors were unable to gain access to verify these conditions during two separate complaints. The property has been the subject of multiple housing maintenance code complaints between 2023 and 2024, with particular attention to unsanitary conditions including mold, sewage problems, and pest infestations.

While some violations have been resolved (such as issues in Apartment 6 concerning a broken window and fire escape concerns, which were certified as corrected in December 2024), others remain open as of the latest inspection in November 2024. The building has maintained a clean record for bedbug infestations, with all annual reports from 2019 through 2025 showing zero affected units. Rodent inspections have shown mixed results, with a compliance inspection passing in March 2024 following a failed initial inspection in January 2024.
