A four-unit 1901 Upper West Side co-op where resident self-management handles building affairs internally while surrounding blocks carry street-level noise and air quality activity.
Built in 1901, this four-unit Upper West Side co-op operates with a self-managed footprint where the corporate officer listed matches a long-term resident. With so few units splitting operating overhead, internal issues get resolved privately while block-level signals paint the surrounding picture. Three things to know:
Self-managed four-unit setup keeps building issues internal. Direct municipal reports against this building are minimal, showing just one rat sighting in August 2025, one missed paper recycling call in April 2025, and one alarm noise report in January 2025. In a four-unit co-op, low filing counts mean operational maintenance is coordinated directly among neighbors rather than logged through agency channels.
Air quality reports surface on the surrounding blocks. Within three blocks of the building, six indoor air quality complaints were logged over the last year, with the most recent filed on May 1, 2026. Indoor air quality issues in historic pre-war clusters often stem from retail exhaust or shared ventilation shaft drift that surfaces inside individual apartments.
Residential noise and interior banging complaints populate the immediate area. Within three blocks of the property, 93 residential noise complaints were recorded over the trailing 12 months, driven primarily by 66 reports of banging and pounding alongside 20 calls for loud music or parties.
