This is a mid-century Carnegie Hill co-op with one open hazardous violation on the books.
Built in 1962, this 46-unit Carnegie Hill co-op keeps most of its business internal — but there is one open Class C violation the city hasn't seen closed. Three things to know:
One Class C violation has been open since April 2025. Class C is the city's 'immediately hazardous' tier — the same bucket as no heat or lead paint. This one is a mice infestation flagged in a single apartment, and it has not been certified closed in nine months. For a co-op that otherwise resolves things internally, an open C sitting this long is worth naming.
A flurry of complaints came from one unit in April 2025. Six separate issues were called in on a single day: ventilation, a power outage, smoke and carbon monoxide detectors, a window guard, and a radiator paint/plaster issue. They were all closed, but the specific cluster points to a notable single-apartment event.
Rodents are a recurring theme, not a one-off. Beyond the open Class C, a separate rodent call came in November 2025 and unsanitary conditions were logged in June. For a prewar Carnegie Hill co-op this is not unusual, but the pattern is real and worth asking about.
