523 West 121st Street, Manhattan, NY 10027

523 West 121st Street is a 6-story, 24-unit New Law Tenement building located in Morningside Heights, built in 1926 and currently owned by Marsha Kolker. The building has maintained an active approach to pest control, as evidenced by consistent bedbug reporting showing no infestations or eradications since 2019. The most recent bedbug report for the period ending October 2024 was filed in January 2025, continuing a pattern of compliance with bedbug reporting requirements.

The property has experienced some maintenance issues over the years, with violations documented in both the Housing Maintenance Code and the Department of Buildings. Recent inspections in 2022 and 2023 revealed administrative violations related to bedbug reporting, while earlier violations in 2018 involved issues with heating system notice posting. A notable cluster of violations occurred in December 1987, primarily involving fire safety concerns including defective fire egress, obstruction in fireproof passageways, and issues with self-closing doors.

These historical violations, along with concerns about combustible material storage and damaged concrete structures, were properly addressed and closed by September 2018. The building's recent maintenance record (2023-2025) shows generally positive conditions, with rodent inspections consistently passing, though a rat activity note was recorded in June 2023. An unresolved Department of Buildings violation from 2019 was dismissed in December 2022, based on subsequent corrections. The property has demonstrated regular compliance with health and safety requirements, maintaining an active approach to pest control and environmental monitoring, though residents should note the building's history of fire safety maintenance requirements from past violations.
