528 West 143rd Street, Manhattan, NY 10031

528 West 143rd Street is a three-story, four-unit residential building located in Hamilton Heights and owned by Sangchoon Cho. Built in 1910, this former Class B building has undergone several regulatory challenges in recent years. Of particular note is an active ECB violation from March 2023 regarding alterations and occupancy issues related to a conversion from SRO to apartments (Penalty: $1,250), and a historical violation from January 2020 concerning incomplete boiler inspection reporting (Penalty: $625).

The building experienced multiple electrical issues in August 2019, with three documented incidents of power outages and lighting failures, though no violations were ultimately issued. Recent inspections (2024) revealed several "C" class violations related to self-closing doors throughout the building, including the main entrance and vestibule doors, along with a "B" class violation for a faulty door stop in the basement. There are also various administrative violations requiring the posting of safety and regulatory notices, including those related to gas leak procedures and building registration.

The property has maintained relatively consistent rodent control measures, with multiple bait applications recorded throughout 2024-2025, though recent inspections have generally resulted in "Passed" findings. Notably, there have been no reported bedbug infestations in the past three reporting periods (2022-2025). Several Department of Buildings (DOB) violations from 2019-2020 related to boiler inspection filings were dismissed in 2024, including failures to submit external low-pressure inspection reports for 2018-2020. The building's electrical system appears to have stabilized since the 2019 incidents, and while there are multiple current violations regarding door safety, the property has generally complied with recent inspection requirements.
