Augrented Insights Report for 5817 4th Avenue

5817 4th Avenue is a three-story, four-unit old law tenement building located in Sunset Park, Brooklyn, built in 1931 and currently owned by Michael Dong. The property has experienced recurring maintenance issues over the past several years, with the most recent significant concerns occurring in December 2023, when the building received violations related to lack of hot water, heating system access, and inadequate safety equipment in the third-floor apartment.

Between 2020 and 2023, the building has faced multiple heat/hot water complaints, with a notable cluster of three separate heat/hot water issues in November 2020, and multiple pest-related complaints that the Housing Preservation and Development (HPD) department was unable to access for inspection. The building's recent history shows some improvement in pest management, with no reported infestations in the past two bedbug reporting periods (2023-2025). However, significant safety and maintenance concerns have persisted, as evidenced by HPD violations issued in 2024 related to various code requirements, including self-closing doors and heating system access.

The Department of Buildings (DOB) records show multiple failed inspection attempts regarding illegal conversion complaints in 2021 and 2023, though these were ultimately closed. Six external low-pressure inspection violations from 2019-2023 were dismissed, and the property has obtained multiple plumbing and electrical permits, suggesting ongoing maintenance and improvement efforts. The most recent bedbug report from February 2025 indicates no current infestations, with the building having maintained a status of zero infested units since 2022.
