NYC Building Report

Manhattan Upper East Side-Carnegie Hill

820 Park Avenue, Manhattan

Residential units

Inferred from ACRIS recorded transfers (deeds and co-op RPTT filings) that name a unit. Combined apartments replace their former unit letters when a later combined transfer exists. This is still not a complete official roster. Latest owner is the grantee on the most recent transfer, not a current occupancy list. The building total is the sum of those last sale amounts over $1, not an assessed or market value.
