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.

What is recorded here
Multiple filings, one stable building identifier.
New York City's Building Identification Number helps connect filings that may use different application numbers or describe different scopes of work. The records below are grouped because they publish BIN 1062449. They should not be read as a single construction project unless the underlying filings say so.
The matched set includes 4 alteration filing. Its latest status categories are 2 approved, 2 under review. Each filing page preserves its own status, dates, scope and source identifier.
