504 West 136th Street, Manhattan, NY 10031

504 West 136th Street, a 6-story, 29-unit residential building constructed in 2006 and owned by Mitch Unger, has experienced recurring maintenance issues in recent years. Most notably, the building has faced multiple challenges with heating and hot water systems, with at least four documented complaints between 2021 and 2024, including a cluster of related complaints in April 2024 that affected the entire building and individual apartments.

In addition, there have been repeated issues with unsanitary conditions, including a pattern of pest-related complaints, with the most recent complaints filed in December 2024 remaining unresolved as of March 2025. The building has also experienced various infrastructure problems, including electrical issues (lights out) and intercom system failures in April 2024, both classified as emergencies. The property has a history of non-compliance with various regulatory requirements, including multiple failures to file mandatory energy benchmarking reports between 2020-2021, and a failure to submit a required exterior wall inspection report in 2018, which resulted in a $625 penalty.

While the building has maintained a bedbug-free status, with no reported infestations in the past eight reporting periods, it has recently faced challenges with rodent activity, as evidenced by compliance inspections in 2024 and 2025 showing consistent rat activity. A Housing Maintenance Code violation was also recorded in March 2023 regarding the filing of annual bedbug reports. The building's management has generally faced difficulties allowing necessary inspections, as evidenced by multiple HPD complaints being closed due to lack of access to inspect the reported problems.
