536 Isham Street, Manhattan, NY 10034

The 5-story, 46-unit building at 536 Isham Street in Inwood, owned by David Radoncic, has been experiencing numerous maintenance issues throughout 2025. As of June 2025, there are multiple open HPD complaints regarding unsanitary conditions (pests), flooring issues, wall conditions, and plumbing problems that remain unresolved despite notifications to the property owner. The building has a documented history of pest infestations, with the most recent Housing Maintenance Code Complaints from June 2025 showing issues with doors, walls, and plumbing facilities.

A significant cluster of violations was recorded in late 2024, particularly affecting apartment A22, which included problems with heating, smoke detectors, mold, and plumbing, though most of these were subsequently closed after inspections and repairs were documented. The property has demonstrated ongoing rodent control challenges, with multiple rat activity reports recorded between 2024 and 2025, though a March 2025 inspection passed without immediate concerns. The building's recent maintenance history shows a mixture of closed and open violations, with some requiring tenant access for resolution.

Interestingly, the building has maintained a bedbug-free record for the past three reporting periods (2021-2024), with only two infestation cases noted in 2020 and 2018, both of which were reportedly eradicated. While there was a minor violation regarding energy efficiency display requirements in 2021, this was dismissed by the Department of Buildings. The persistent nature of the current open complaints and the sequence of maintenance issues throughout 2024-2025 suggests ongoing challenges with building upkeep and resident comfort.
