5819 4th Avenue, Brooklyn, NY 11220

5819 4th Avenue is a three-story, four-unit old law tenement building located in Sunset Park and owned by Xu Dong. Built in 1931, the property has experienced several notable maintenance and safety issues in recent years.

Most pressing are multiple active and unresolved violations from 2023-2024, including an ongoing issue with broken vinyl floor tiles in the public hall on the third story, and several problems in unit 3L involving defective plaster surfaces, improper heating installation, and maintenance violations. The building has also faced safety concerns, with violations documented in July 2024 regarding an illegal double-cylinder lock at the building entrance and defective self-closing doors to the rear yard and cellar. The property has a history of heat and hot water issues, evidenced by a 2019 complaint that HPD could not inspect due to lack of access.

While the building has maintained a record of zero bedbug infestations in recent years (as per official reports from 2019-2025), there have been multiple housing maintenance code violations that required attention, including combustible material accumulation and fire safety concerns in the cellar. The Department of Buildings has issued multiple violations for failure to file external low-pressure inspections between 2018 and 2021, though most of these have since been dismissed. Recent permits for plumbing and electrical work were issued in July 2023, indicating some ongoing maintenance activity, but the number of open violations and recent issues suggests that various building systems and safety features may require continued attention.
