Prewar Carnegie Hill co-op built in 1925, sitting above a busy stretch of Madison Avenue retail.
This sixty-unit building has been held by its cooperative corporation for decades. Because it is a co-op, building-specific issues typically resolve internally, leaving the public record mostly focused on the surrounding blocks and ground-floor storefronts. Three things to know:
Commercial kitchen venting and exhaust issues crop up around the ground floor. Seven food establishment complaints and three indoor air quality reports were filed within three blocks over the last year, with the most recent air quality call logged on July 21, 2026. Sharing a physical plant with retail can mean vapor or food smells drifting up through common risers.
Double-parking and blocked hydrants crowd the surrounding avenues. The blocks around the building saw 93 illegal parking complaints over the last year. These calls concentrate around fire hydrants and crosswalks—indicating a constant cycle of short-term delivery drop-offs rather than long-term vehicle storage, with the most recent call logged on July 24, 2026.
The cooperative maintains a wide pricing spread between its largest and smallest layouts. Recent transactions show a massive variance in unit sizes and values, with a $5.45M sale closing in late January 2026 and a $995,000 transaction closing just a week later. This means the shareholder base spans highly diverse apartment sizes.
