Augrented Insights Report for 621 West End Avenue

At 621 West End Avenue, an Upper West Side building owned by Martin Scharf, significant recent maintenance issues have emerged, particularly related to water and heating systems. Most notably, there is an open water leak complaint from February 2025, following a power outage in May 2025 where the Housing Preservation and Development (HPD) was unable to complete an inspection.

Multiple water-related incidents were documented in 2024, including heavy flow, slow leaks, and damp spots, with some violations issued. The building has experienced recurring heating and hot water system problems, with multiple complaints in 2022 and 2024, though some were resolved with confirmed restoration of services. Apartment 1E has been identified with several maintenance issues as of May 2024, including missing smoke and carbon monoxide detectors, a defective self-closing door, broken wooden floor, damaged plaster surfaces, and bathroom tile issues.

The building has undergone multiple rodent inspections between 2022 and 2025, with the most recent inspections in 2024 and 2025 passing, though earlier inspections in late 2022 showed rat activity and bait application. A sidewalk safety violation was recorded in October 2020, resulting in a penalty, but there have been no recent environmental violations. Importantly, the building has maintained a clean record regarding bedbug infestations over the past several years, with no reported cases between 2019 and 2024.
