527 West 23rd Street, Manhattan, NY 10011

527 West 23rd Street is a 14-story, 313-unit residential building in Chelsea, constructed in 2001 and currently owned by Christopher Schmidt. The building has experienced recurring indoor air quality issues, with two documented complaints in 2023 (June and March) related to ventilation and chemical vapors, for which the Department of Health and Mental Hygiene sent advisories to the management. In 2021, a significant mold problem was identified in apartment 6F's bathroom, resulting in violations from the Housing Preservation and Development department.

The building has had multiple elevator-related violations, particularly notable in 2019 when three separate violations were issued for failure to correct defects from a 2017 inspection, though these were eventually resolved with penalties paid. The property has maintained an active response to pest control, with regular reporting showing zero bedbug infestations in the most recent reports (2023-2024), despite previous incidents requiring eradication efforts between 2020-2022. Rodent inspections have consistently passed since 2010, showing effective pest management.

The building has faced several complaints regarding illegal after-hours work, with the most recent occurring in August 2023, though no violations were found upon inspection in each instance. Additionally, there were two notable energy efficiency violations in 2021 and 2023 related to the failure to display required energy scores, though both were dismissed. The property has maintained regular permit issuance for various maintenance and repair work, with multiple permits issued throughout 2019 for electrical and plumbing work.
