150 West 121st Street, Manhattan, NY 10027

150 West 121st Street is a 4-story, 10-unit residential building in Harlem, built in 1887 and currently owned by Salvatore Davola. The property has experienced several significant maintenance and safety issues in recent years, with the most pressing concerns being two active DOB violations from September 2024: one regarding failure to maintain the building in a code-compliant manner, particularly concerning dislodged and leaning masonry walls from the basement to the second floor, and another regarding failure to certify correction of immediately hazardous violations.

There is also a notable open complaint from 2020 regarding unsanitary mold conditions, and a previous heat/hot water complaint from 2020 that remains unresolved. The building has a history of infrastructure problems, including multiple heating and hot water complaints (in 2020 and 2022), plumbing issues (most recently in June 2024), and fencing problems (May 2024). Health concerns have been documented, including rat sightings in 2024 and 2021, though the most recent bedbug report from December 2023 indicated no infestations during the reporting period.

Earlier structural concerns were evident in 2024, with complaints about building shaking and structural stability, though a construction safety compliance action from April 2025 had its stop work order fully rescinded. The property previously experienced issues with its boiler system in 2019, received violations for construction work outside approved plans in 2021, and had sidewalk safety concerns that same year. While some complaints have been resolved through inspections and corrections, the presence of multiple open violations and maintenance issues suggests ongoing property management challenges.
