1601 St Nicholas Avenue, Manhattan, NY 10040
The 40-unit, 6-story apartment building at 1601 St Nicholas Avenue in Washington Heights, built in 1913 and owned by George Huang, has experienced significant maintenance and health-related issues in recent years. The property currently has multiple open complaints and violations, including ongoing concerns about water leaks (opened May 2025), pest issues (insects/pests complaint from June 2025), and unsanitary conditions (garbage/recycling storage violation from June 2025). A notable pattern of mold-related problems has emerged, with six separate complaints recorded between February and March 2025, some designated as emergency situations.
The building has also faced serious infrastructure challenges, including multiple heating, ventilation, and plumbing issues, with at least four separate complaints regarding ventilation systems, water supply problems, and appliance malfunctions between January and March 2025. The building's violation history reveals persistent maintenance challenges, particularly in apartment 54, where violations for roach infestation, lead-based paint hazards, and various repair issues were recorded during a December 2024 inspection. Apartment 31 has documented problems with water leaks, window repairs, and door issues, all noted in October 2024 inspections. The building's management has shown some responsiveness to violations, with several being closed after inspection, though notable issues remain open.
Recent rodent inspections have shown mixed results, with three consecutive inspections in 2024 indicating rat activity, while more recent inspections in 2025 passed. The property has maintained a clean record for bedbug infestations, with zero reported cases from 2021 through 2025. Recent complaints have also been filed regarding elevator service and various building maintenance issues, though some complaints from 2024 regarding work without proper permits and other maintenance matters were closed with no violations found. The owner has complied with some regulatory requirements, as evidenced by the dismissal of multiple violations related to Energy Efficiency Reports (EER) and Benchmarking Reports, though these were only addressed after citations were issued.
