- 0Information order
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.
Owner of record

As the assessment roll records it. Only owners that read as a company are shown here; where the roll names an individual, nothing is published.
Lot facts come from NYC Department of City Planning, Primary Land Use Tax Lot Output (PLUTO) (64uk-42ks), accessed Sep 26, 2026. They describe the tax lot, not any single filing. When the rest of New York went up
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 1090764. They should not be read as a single construction project unless the underlying filings say so.
The matched set includes 1 alteration filing. Its latest status categories are 1 approved. Each filing page preserves its own status, dates, scope and source identifier.
