Augrented Insights Report for 239 East 51st Street

This 5-story, 10-unit Old Law Tenement at 239 East 51st Street in Midtown, owned by Howard Li and built in 1900, has experienced several significant maintenance and safety issues over the past few years. Most recently, in October 2023, inspections revealed rodent activity prompting health department violations, with a follow-up inspection in February 2025 passing compliance.

The building has had recurring rodent problems, with inspection results showing rat activity in 2017, 2018, and 2023-2025. The property has also faced multiple air quality concerns, including chemical vapors in December 2022 and construction dust in July 2020. Significant violations were documented during a 2019 construction period, including inadequate tenant protection plan compliance, removal of fire stopping, unauthorized electrical work, and poor housekeeping, resulting in various fines totaling $12,500.

The building has had multiple inspection-triggered complaints regarding garbage storage (2018-2019), door issues (2018-2019), and a heat/hot water complaint in June 2019 where inspectors were unable to gain access. Despite these challenges, recent bedbug reports (2020-2025) show no active infestations. The property has maintained regular permit issuance for various works, with records indicating consistent oversight and attempts at maintenance, though many historical complaints have resolved without violations being found upon inspection.
