Augrented Insights Report for 839 Bay Ridge Avenue

The 6-unit, 3-story New Law Tenement building at 839 Bay Ridge Avenue in Dyker Heights, owned by Xuehong Yang, has experienced recurring heat and hot water issues over recent years, with the most recent incidents occurring in January 2025 (apartment only) and October 2023 (entire building), both of which required HPD intervention. The building has also faced several maintenance challenges, including a significant pest control situation in 2023 when roach and mice infestations were reported in apartment 3F, along with multiple code violations related to heating and hot water supply, particularly affecting the same apartment.

Additional violations have been documented regarding self-closing doors in the public hall and encumbrances in the 3rd-story hallway. The building underwent multiple emergency inspections in 2021 related to plumbing, electrical, and unsanitary conditions, though no violations were found during those inspections. The property has maintained active compliance with bedbug reporting requirements from 2019 through 2025, consistently reporting zero infested units.

Recent inspections reveal one open violation from 2023 regarding access to the building's heating system in the basement, while previous bedbug-related violations from 2022-2024 were appropriately closed. Two complaints in 2024 regarding construction plans and fencing, and a 2020 complaint about possible illegal conversion, were all found to have "No Violation Warranted" upon inspection. Despite the building's age (constructed in 1931), the property has shown to be generally responsive to inspection requirements, with most violations being addressed and closed through proper certification processes, though the recurring heating system issues suggest an ongoing maintenance concern.
