21 Stanley Avenue is a walkup apartment building built in 1915 in Staten Island with 3 residential units. It carries a Grade F health score, with 10 open Class C hazardous violations and a recurring pattern of habitability complaints (heat, electric, elevator, mold, lead, boiler, or unsanitary conditions) among the recorded concerns. Our analysis reviewed 281 records across 25 public data sources, benchmarked against similar small prewar residential buildings in NYC.
18 open violations are past the city's repair deadline. 10 hazardous (Class C) violations remain open in city records (4 opened in the last 2 years).
The grade measures tenant living conditions from public city records (violations, complaints, litigation). It is not a structural or construction-safety rating.
