521 West 149th Street, Manhattan, NY 10031

The 8-unit, 3-story building at 521 West 149th Street in Hamilton Heights, owned by W.149 Acquisition Corp., has experienced several notable maintenance and compliance issues over recent years. The property, constructed in 1900 and classified as HERETOFORE CONVERTED CLASS A, has a concerning pattern of heating and hot water system problems, particularly evident in late 2019 when emergency complaints were filed in both November and December regarding heat and hot water issues affecting the entire building.

These incidents led to multiple violations, including problems with the heating system access and inadequate heat and hot water supply to Apartment 2S. More recently, in 2024, the building was cited for failing to file its annual bedbug report, though previous filings from 2021-2022 and 2019-2020 indicated zero infested units. Significant safety concerns were documented in December 2019 regarding gas system compliance, resulting in an active Environmental Control Board violation for gas being supplied without proper inspection and certification, along with an open DOB violation for failing to file the 2022 external low-pressure inspection.

The building has undergone multiple rodent inspections between 2019 and 2025, with the most recent results showing passing compliance, though there were instances of rat activity noted in 2024 and 2023. The property has maintained up-to-date bedbug reporting requirements in 2023, showing no current infestations, and has addressed various building code compliance issues over the years, though some violations remain open as of 2025. While the building has experienced various maintenance challenges, recent inspections suggest improved conditions, particularly regarding rodent control, with multiple consecutive passing inspections.
