Augrented Insights Report for 428 47th Street

The three-story, four-unit residential building at 428 47th Street in Sunset Park, owned by Min Jiang and built in 1923, has experienced several significant maintenance and safety concerns over the past five years. Most notably, in March 2020, there were multiple complaints regarding water supply issues and cooking gas problems, with some complaints being classified as emergencies.

There was also an unsanitary condition complaint regarding garbage/recycling storage, though HPD inspectors were unable to gain access in several cases. Between 2021 and 2024, the building received four consecutive Bedbug Reporting violations under § HMC for failing to file annual bedbug reports, though recent records from July 2025 show no current infestations or eradication issues. The building has faced multiple complaints about potential illegal conversions and improper uses, with inspection access repeatedly denied, most recently in 2023.

A December 2021 complaint regarding blocked egress resulted in an Oath Violation being served. Additionally, the building received an ECB violation in December 2021 regarding obstructed access at front porch stairs, though this issue was resolved with no penalties imposed. The most recent bedbug reporting shows proper compliance with no current infestations, indicating improved attention to this particular maintenance requirement, while also reflecting positively on the building's overall current condition.
