MASTER LIST · TRUE UNIVERSE

Every condo & co-op in NYC.

Pulled from PLUTO — NYC's tax-roll tax-lot file. Condos identified by umbrella BBL pattern (lot ≥ 7500, building class R*); co-ops by D-class building code plus cooperative-corporation ownership. This is the denominator everything else on this site compares against.

How this list is built

Two PLUTO queries against NYC DOF's tax-lot file (64uk-42ks):

Condos: lot ≥ 7500 AND bldgclass like 'R%' — every condominium umbrella BBL. Returns 10,882 buildings.
Co-ops: bldgclass in ('D0','D1','D3','D4','D5','D6','D7','D8','D9','C8') AND owner contains 'CORP' — every D/C-class building owned by a cooperative corporation. Returns 3,180 buildings.

Known gaps

HDFC co-ops not owned by a "CORP"-suffix entity are missed. Adding HDFC NTAs or other owner-string patterns would close this. Rough estimate: 800–1,200 additional buildings.
Mitchell-Lama co-ops structured as separate corporate entities are mostly captured but some edge cases (housing companies with non-CORP suffixes) miss.
Some condo unit BBLs appear as separate records (lot 1001–7499) for individual unit-level data. Counts above are umbrella-BBL only, which is what you want for "buildings" — but if you click "Sort: Largest first," some R-class records with high unit counts are the umbrella, not a unit.
Brand-new condos with offering plans filed but no PLUTO record yet won't appear until the next PLUTO version (refreshed ~quarterly).
