517 West 59th Street is a 34-story, 465-unit residential building constructed in 1973, currently owned by Thomas Ahn. The property has experienced recurring issues with its heating and plumbing systems over the past several years, with multiple complaints and violations related to heat and hot water failures affecting both individual apartments and the entire building. Most recently, in 2025, there were two incidents involving heat/hot water problems and one water supply issue, all of which were investigated by HPD though some were resolved without violations.

Significant violations were documented in September 2024, including broken steam pipes in the boiler room and hot water issues in apartment 30E. A water leak incident requiring attention was reported in June 2024. The building's elevator system has been a recurring complaint subject to inspection, though no violations were found during inspections in 2020-2021. The building's maintenance history shows attention to various maintenance issues, with documented pest control efforts including bedbug inspections showing varying levels of infestation between 2019-2024, though recent reports from 2024-2025 indicate no current infestations.

Rodent inspections have generally resulted in "Passed" results, with one instance of rat activity noted in September 2023. The property has active DOB violations for failing to submit an Elevator Inspection Report (EER) for multiple years (2021-2022). Historical records show previous issues with water supply systems, including multiple complaints in 2020 and 2021, though these were often related to other ongoing building-wide problems. While there have been various maintenance issues documented through 311 complaints and DOB inspections, the building has generally addressed these through HPD inspections and compliance measures, with most violations being resolved in a timely manner.
