Augrented Insights Report for 511 West 143rd Street

The 6-story, 31-unit building at 511 West 143rd Street in Hamilton Heights, owned by West 143 Partners LLC, has experienced several significant maintenance issues in recent years. Most notably, in May 2025, multiple open complaints were filed regarding building conditions, including problems with the bell/buzzer/intercom system, various paint/plaster issues, flooring concerns, and pest infestations.

During the same month, there were also heat and hot water complaints that could not be inspected due to access issues. The building has a documented history of elevator-related problems, with multiple complaints between 2019 and 2024 regarding single-device operation and lack of alternate service, though recent inspections in 2023 show no violations. Apartment 54 has multiple open violations from an August 2024 inspection, including issues with plaster surfaces and paint on ceilings and walls, while apartment 53 had violations related to carbon monoxide detector replacement and smoke detector repairs.

The building experienced significant infrastructure issues, with a 2024 Environmental Control Board violation citing large steam leaks in the boiler system affecting the cellar. Historical complaints indicate recurring problems with pest control, building safety systems, and maintenance of common areas, though more recent rodent inspections in 2023 and 2024 passed without incident. The property has maintained a zero-infestation record for bedbugs over the past four reporting periods from 2020 through 2024.
