643 West 171st Street, Manhattan, NY 10032

643 West 171st Street is a 5-story, 31-unit New Law Tenement building located in Washington Heights and is currently owned by Michael Aryeh. The building, constructed in 1914, has experienced several recurring maintenance issues in recent years, most notably related to unsanitary conditions and plumbing problems. In April 2025, multiple complaints about pest infestations were logged and resulted in violations, while plumbing issues involving the bathtub/shower remain unresolved as of July 2025.

The building has also faced water-related problems, with complaints about damp spots and mold recorded between January and March 2025, though these were not found to violate housing laws during inspections. The property has a documented history of violations and maintenance concerns dating back to 2022, including problems with self-closing doors in the vestibule and common areas, and an open violation regarding roach infestation in Apartment 54 from September 2022. An active ECB violation from October 2022 involving illegal key lock hardware was recorded, and there remains an open violation related to the 2017 boiler inspection.

The building's bedbug reports from 2019 through 2025 show no documented infestations, and it has consistently passed rodent inspections from 2018 to 2025, with only one incident of rat activity noted in July 2021. Recent housing code compliance has improved, with multiple violations from previous years being resolved, though some recent maintenance issues remain outstanding as of July 2025. The building underwent some permitted work in late 2018, indicating ongoing maintenance and improvement efforts by management.
