520 East 83rd Street, Manhattan, NY 10028

520 East 83rd Street is a 5-story, 11-unit old law tenement building located in Manhattan's Upper East Side, owned by Sefik Gunes and constructed in 1910. The property has experienced recurring issues with heat and hot water, particularly during the winter of 2020-2021 and again in 2023, with violations issued for inadequate systems affecting multiple apartments.

More recently, in 2025, there have been ongoing concerns with mold issues, with the most recent HPD inspection being inconclusive and requiring tenants to submit new complaints if problems persist. The building has also faced maintenance challenges, including a significant water leak reported in 2019, and multiple housing code violations related to the condition of public areas and building systems, including locked heating system access and inadequate hot water provision, all of which have been subsequently addressed and certified as corrected. The property has undergone regular rodent inspections, with mixed results.

While the most recent inspections in 2023 and 2024 passed, there were periods of rat activity requiring bait application in 2021 and 2022, though these were addressed through pest control measures. The building has consistently reported zero bedbug infestations during the annual reporting period from 2018 through 2024, indicating effective pest management in this regard. The property's maintenance record shows a pattern of addressing violations and complaints, though the recurring nature of heat, hot water, and mold issues suggests these remain persistent challenges for residents.
