1411 Madison Avenue, a 5-story, 8-unit residential building located in East Harlem and built in 1920, has experienced several significant maintenance and safety events over recent years. Most notably, there have been four tenant safety inspections in December 2021 and December 2023, with the latter resulting in an Oath Violation being served. The building underwent multiple electrical safety issues in December 2021, including unauthorized electrical work and temporary electrical installations, leading to four Environmental Control Board (ECB) violations totaling $7,350 in penalties, though these have since been resolved. In 2022, there were three instances of failure to certify corrections on immediately hazardous (Class 1) ECB violations, though these violations were eventually dismissed.
The building's more recent history shows some continuing challenges with building maintenance and safety. In early 2023, there were reports of rat activity during a rodent inspection, though subsequent inspections in late 2023 and 2024 returned passing results. The most recent tenant safety inspection in December 2023 has resulted in correspondence with the Department of Buildings regarding non-compliance with a previous order. Despite these issues, the building has maintained a clean record regarding bedbug infestations since 2019, with no reported cases in the past six filing periods between 2019 and 2024. The property is currently owned by Thomas Ahn and has undergone various permitted electrical work, as evidenced by permits issued in 2019. The building's inspection history shows a mix of passing and failing results, particularly during 2023-2024, suggesting ongoing attention to maintenance and compliance requirements is necessary.
