518 West 135th Street, Manhattan, NY 10031
The 6-story tenement building at 518 West 135th Street in Harlem, built in 1905, has experienced several significant maintenance and safety issues over the last several years under current ownership by Angel Ortega. Most recently, in 2025, there was an immediate heat/hot water emergency affecting the entire building, following similar incidents in 2020 and 2022.
The building has also faced recurring problems with unsanitary conditions, including a notable mold issue in apartment 3A in 2022, along with rodent sightings, including a March 2021 rat sighting, and multiple rodent activity inspections showing mixed results between 2021 and 2025, with the most recent inspection in May 2025 passing. The property currently has two active violations with the Department of Buildings related to inspection filing requirements - one for the 2018 external low pressure inspection and another for the 2017 boiler inspection.
A 2023 inspection revealed several safety concerns, including an illegal panic bar on the roof access door and obstruction of fire escape egress by flower pots on the 4th-story balcony. In terms of bedbug management, the building has maintained proper reporting requirements, with no reported infestations in the last two filing periods (2021-2022 and 2019-2020). While some repairs have been completed - such as addressing the mold and bathroom issues in apartment 3A - the building continues to experience periodic violations and service disruptions that affect resident comfort and safety.
