Augrented Insights Report for 601 West End Avenue

601 West End Avenue is a 14-story, 26-unit residential building located in Manhattan's Upper West Side, constructed in 1916 and currently owned by Robert Ludwig. The building has undergone various regulatory reviews and inspections over the past several years, with the most recent activity centered around construction-related complaints and a stop work order in April 2025, though inspections found no violations.

Between 2019-2022, the property experienced multiple ventilation system issues and indoor air quality concerns, with violations recorded for water damage and plaster issues in the BASEME apartment. Environmental Control Board violations from 2022 noted problems with a rooftop exhaust fan's noise and vibration, while 2020 recorded issues with construction work not following approved plans, resulting in a $625 penalty. The building has maintained a clean record regarding pest issues, with consistent rodent inspection passes from 2018-2025 and no bedbug infestations reported in the last eight annual filings.

Recent service requests include a 2024 complaint about smoke/odor from a mobile food vendor, and earlier complaints in 2021 and 2019 regarding ventilation and indoor air quality. The property has undergone several permitted construction and maintenance projects between 2019-2021, with permits issued for various types of work including elevator modernization (2020) and other general maintenance tasks. Recent compliance inspections have generally shown passing results, and the building has not recorded any bedbug infestations since 2019, though there was one recorded infestation case in 2019 which was reportedly eradicated.
