Open means the Department of Housing Preservation and Development has not recorded it as corrected, which is not the same as nobody having fixed it. The city publishes the apartment each was written against; that is not carried here, because a count says a building has a problem and an apartment number says whose.
The apartments
12 condominium apartments are assessed on this block, and the typical one is 1,148 sq ft (107 m²). They run from 51 to 157 m².
The city values the typical one at $421,875. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.

What is recorded here
Multiple filings, one stable building identifier.

The matched set includes 4 alteration filing. Its latest status categories are 4 approved. Each filing page preserves its own status, dates, scope and source identifier.
