Small Central Harlem HDFC co-op facing active heat, access, and building-wide maintenance violations.
A small 9-unit Central Harlem cooperative operating under the Madison Avenue Housing Development Fund Corp (HDFC) affordable structure. Unlike co-ops that keep operational friction internal, this address carries active code citations for core building systems alongside police calls from the address. Three things to know:
Thirty open housing-code violations, with ten classified as immediately hazardous. The building carries 30 open housing-code citations, with 10 marked Class C immediately hazardous. February 2026 filings detail a locked boiler room blocking access to the heating system, active heat deficiencies in unit 5A, and roach infestations in unit 1A. Additional violations flag broken fire-retardant hall materials, missing mailbox detector notices, and an unrepaired fire door knob.
A concentrated cluster of police-directed complaints logged at the building. Nineteen non-emergency calls were logged directly from this address in mid-2026. Rather than standard apartment noise, these calls cite uncategorized police matters, pointing to ongoing access or security friction around the entrance and public halls.
Indoor air quality and odor calls surface in the three blocks around the building. Within three blocks, 11 indoor air quality calls were logged over the trailing year. While the building's own record focuses on heat and access, air quality and odor signals nearby can indicate HVAC or riser bleed that only becomes apparent after moving in.
