The 6-story, 61-unit residential building at 545 West 236th Street in Riverdale, owned by Ronald Katz and built in 1939, has experienced several notable maintenance issues in recent years. Most concerning are the recurring heat and hot water problems, with complaints reported in January 2025 and December 2024 affecting both individual apartments and the entire building, though these issues were resolved upon inspection. The building has also faced multiple sanitary challenges, particularly between September and October 2024, including garbage/recycling storage issues, mold, and pest problems, with some violations issued during these inspections. There are active violations related to the building's exterior facade, with two Environmental Control Board violations issued in September 2024 regarding cracked spalling brick/mortar joints, with penalties totaling $5,000. The building's third floor apartment 3D has multiple open violations from September 2024 concerning water leaks, defective plaster surfaces, and lead paint hazards, though some violations from this inspection were certified as corrected by December 2024.
Additional infrastructure concerns include plumbing issues, as demonstrated by multiple emergency complaints in 2025, and a history of elevator problems, with a 2020 violation for an inoperative phone being documented. Recent rodent inspections in 2024 and 2025 have shown evidence of rat activity, though this has not been consistently reported in previous years. The building's maintenance history shows some improvements, as demonstrated by the bedbug reporting showing no infestations in recent years after previous occurrences in 2018-2019, and the absence of recent elevator-related complaints since the 2020 violation was addressed. The property has had several building department complaints and inspections, including a 2024 vibration complaint that was investigated but found no violations.
