508 West 136th Street, Manhattan, NY 10031

The 25-unit, 6-story tenement building at 508 West 136th Street, owned by Ethan Rozenblatt, has experienced significant maintenance and infrastructure challenges over the past several years. Most recently, in April 2025, there were emergency complaints about unsanitary mold conditions and heavy water leaks, though HPD was unable to complete inspections of these issues. The building has a concerning history of water-related problems, including multiple plumbing issues in 2024 (July) that resulted in violations, and a heat/hot water emergency affecting the entire building in January 2024.

Apartment 14 emerged as a focal point for various maintenance issues in 2024, with violations issued for water leaks, gas supply problems, and damaged plaster and paint affecting both the apartment's interior and hallways. The property has an active violation history with the Department of Buildings (DOB), including three current violations for failure to file external low pressure inspections (2018-2020). A gas utility referral from 2019 also resulted in a violation.

While bedbug reports from 2022-2024 show no infestations, the building has experienced persistent rodent issues, with multiple inspections between 2023 and 2025 consistently showing rat activity. Additionally, there were various housing maintenance code violations in 2024 related to walls, flooring, and pests that were subsequently closed, though the repeated nature of these issues indicates ongoing maintenance challenges. The building's age (constructed in 1905) and these documented issues suggest a pattern of infrastructure and maintenance concerns that have required ongoing attention from both management and city agencies.
