The five-story residential building at 852 Amsterdam Avenue, owned by Christopher Orpheus, has experienced a notable number of maintenance issues and violations since 2021, with the most recent activity occurring in 2025. As of April 2025, there are multiple open complaints related to building conditions, including issues with doors, flooring, and walls. Recent emergency complaints in 2025 have focused on door problems, with violations issued in April 2025, and there are ongoing concerns about flooring and wall conditions from January 2025. A heating system issue affecting the entire building was reported in February 2025.
The building has a documented history of maintenance violations, including a 2023 violation regarding the front wall's cement stucco and window moldings, and a 2022 violation related to rust on balcony components. Apartment 4N has experienced several specific issues in 2021, including problems with vinyl floor tiles, electrical extension cords, and plaster surfaces. The property has also faced compliance challenges, with multiple inspections between 2021-2023 resulting in "no violation warranted" dispositions, particularly regarding various construction-related complaints in 2023. While there have been no recorded bedbug infestations in recent years (2019-2024), rodent inspections indicate persistent rat activity, with multiple failed inspections in 2023-2024 requiring bait application and indicating ongoing pest control challenges.
The building's maintenance history reveals a pattern of deferred maintenance and ongoing compliance issues, though some violations have been addressed and closed. The property has consistently reported zero bedbug infestations since 2019 and has shown varying results in rodent inspections, with some passing inspections but recurring rat activity noted. The building's environmental control violations from 2023 related to sidewalk shed installation resulted in a penalty of $2,430, though this was later resolved. The property has been subject to multiple building inspections for various issues, with many resulting in "unable to gain access" notations, indicating challenges in addressing certain complaints and violations.
