23 West 123rd Street, Manhattan, NY 10027

23 West 123rd Street is a 5-story, 5-unit Old Law Tenement building in Harlem, owned by Uptown Gambit, Inc. The property, constructed in 1896, has experienced several significant maintenance and safety issues over the past two years, with the most pressing concerns revolving around heating and plumbing systems. From March to May 2025 alone, there were multiple complaints about heat/hot water issues throughout the building, and four separate rodent-related incidents, including one rat sighting and reports of conditions attracting rodents.

These service requests indicate ongoing challenges with building maintenance and sanitation. The building's heating system has been a particularly persistent problem, with multiple boiler-related complaints and problems with access to the heating system documented between late 2023 and 2024. According to the Department of Buildings, there are currently active violations regarding the failure to file required external low-pressure inspections for multiple years (2020-2023), and a notable ECB violation with a penalty of $3,125 relating to failure to provide access to the heating system.

In addition to these issues, there are several open violations from 2024-2025, including problems with self-closing doors, garbage storage, and safety signage requirements. Rodent inspections throughout 2024-2025 have consistently shown evidence of rat activity, though recent bait applications have been noted. The building has also experienced challenges with access for inspections, as evidenced by multiple "Inspector Unable to Gain Access" records during both 2024 and 2025, particularly concerning the boiler system and heat/hot water complaints.
