423 West 144th Street, Manhattan, NY 10031

The 4-story, 4-unit building at 423 West 144th Street in Hamilton Heights, owned by Sandra Griffin, has experienced recurring heat and hot water issues in early 2025, with complaints filed in February and March that were documented as emergencies by the Housing Maintenance Code. The building has persistent violations related to bedbug reporting requirements, with open violations recorded for the years 2021-2024.

In recent years, there have been serious concerns regarding unauthorized transient use of the property, particularly involving illegal hotel rooms; most notably, three active ECB violations from September 2023 involving fire safety and egress requirements for a suspected transient use of apartment 4F, with penalties totaling $37,500. The Department of Buildings also recorded complaints in 2022 and 2023 regarding work without permits and illegal hotel room operation, though access could not be gained during the inspection in 2022.

Despite these issues, the building has consistently passed rodent inspections between 2016 and 2025, indicating no pest-related violations during this period. The property, constructed in 1898, is classified as a "HERETOFORE CONVERTED CLASS A" building and has maintained its Class A Multiple Dwelling status according to its Certificate of Occupancy.
