505 East 70th Street, Manhattan, NY 10021
The 37-story residential building at 505 East 70th Street in Manhattan's Upper East Side, owned by Kenrick Ou and constructed in 1987, has experienced several notable maintenance and habitability issues over recent years, particularly related to heat/hot water systems and mold. Between 2021 and 2025, there have been multiple emergency complaints regarding building-wide heat and hot water outages, with documented responses showing restoration in some cases. More recently, in 2024, a mold violation was issued for Apartment 22X, and as of April 2025, this appears to still be open.
The building has also had recurring issues with bedbug infestations, with the most recent reports (2023-2024) documenting one infested unit each year, though all were reported as eradicated. Other notable concerns include a period of sanitary violations in 2023 related to garbage/recycling storage, and a 2024 inspection that revealed exterior facade maintenance issues, with spalled bricks documented on multiple elevations. The property has undergone several safety inspections, including multiple Tenant Safety Inspections in 2023, all of which were found to have no violations.
While there have been complaints about various building conditions, many have been resolved promptly, including food establishment inspections by the Department of Health. The building's management has obtained various permits for maintenance work, particularly in 2019-2021, suggesting ongoing maintenance efforts. Historical records show that while most building and housing maintenance code violations have been addressed, there remains an open mold violation as of 2025. The building's unit count stands at 517, representing a significant residential population in one of Manhattan's established neighborhoods.
