521 West 145th Street, Manhattan, NY 10031

The 5-story, 79-unit residential building at 521 West 145th Street in Hamilton Heights, owned by Andrew Kleiman, has experienced several recurring maintenance issues, particularly regarding heating systems and window conditions. Most recently, in 2025, there have been three door-related complaints in May and June, with at least one resulting in violations. The building has a documented history of heating problems, with multiple heating and hot water complaints in 2024 and 2025, particularly during winter months, though some of these complaints were marked as resolved or inspected without confirmed violations.

Window maintenance has emerged as a significant issue, with ongoing problems documented in recent Housing Maintenance Code Violations, particularly affecting apartments 3H, 3Q, and 4E, related to defective window components and glass panes. The building has been actively monitored for pest control, with the most recent bedbug reports from 2022-2024 showing minimal infestations (only reported in 2021 and 2022, with eradications confirmed). Recent rodent inspections have varied in results, with the latest inspection in June 2025 passing, though there was a rat activity report in May 2025.

Additional concerns include a 2024 incident involving mold remediation in apartment 2H and ventilation issues documented in early 2023. The property has outstanding Department of Buildings violations from June 2023 related to failure to file external low-pressure inspections. Despite these ongoing maintenance issues, the building has generally maintained compliance with housing regulations, as evidenced by the regular closure of most complaints and violations through HPD and other agencies, though some open violations remain under review.
