520 West 23rd Street, Manhattan, NY 10011

520 West 23rd Street is a 15-story, 107-unit residential building constructed in 2003 and managed by 520 West 23rd Street Corp. The property has experienced several significant maintenance issues in recent years, most notably in mid-2024 when violations were issued regarding non-compliant door mechanisms at both the 1st-story public hall fire door and laundry room door, where devices preventing the doors from being self-closing were found. The building has also faced recurring air quality concerns, with complaints recorded in October 2023 and April 2019.

A concerning pattern emerged in 2019 with multiple complaints regarding illegal hotel rooms in residential buildings, blocked egress points, and construction-related issues, though inspections generally resulted in no violations being issued. The building's elevator system underwent inspections in 2019 and 2024, with one violation related to unspecified conditions being resolved by June 2024. More positively, the building has maintained consistent pest control measures, with zero bedbug infestations reported in the most recent four annual filings from 2021-2024, and all rodent inspections since 2010 have resulted in passing grades.

The property had some balcony maintenance issues noted in 2018, involving flower pots and construction materials, though these appear to have been addressed. The building's management has also demonstrated compliance with various housing maintenance requirements, though there have been instances requiring intervention from city agencies, such as the Department of Housing Preservation and Development and the Department of Health and Mental Hygiene. While the building's recent history shows improvements in pest control and rodent management, the air quality issues and door mechanism violations in 2024 suggest ongoing maintenance challenges that warrant attention.
