AI summary · updated June 2026

The four-story, three-unit residential building at 617A Vanderbilt Avenue, owned by Johnsie Mitchell, was constructed in 1901 and has experienced several notable maintenance issues over the past few years. The property has faced recurring problems with heat and hot water systems, particularly during a significant period between late 2020 and early 2021 when multiple emergency complaints were filed regarding entire building heating problems. While these issues appear to have been resolved, the building experienced pest-related challenges in 2021, including multiple complaints about rodents and unsanitary conditions, though inspections did not always result in violations being found. The most recent bedbug reporting period (2022-2023) indicated infestation in all three units, representing a deterioration from the 2023-2024 period which reported no infestations.

The building has undergone regular rodent inspections since 2017, with all recent inspections (2022-2025) showing passed results, suggesting improved conditions in this regard. Housing Maintenance Code violations have been relatively stable, with several Class A violations related to bedbug reporting observed between 2021-2024. There are currently several open Class B and C violations from 2020-2021 that require attention, including issues with water leaks, heating systems, door functionality, and plastered surfaces in Apartment 1. The property has maintained a generally adequate response to complaints, though there have been instances where inspectors were unable to gain access for verification. An illegal commercial use complaint from 2018 was investigated but found no violations. The building's age and history suggest ongoing maintenance challenges, though recent rodent inspections indicate some improvement in pest management.
