- 0Non-hazardous
- 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.
Lot facts come from NYC Department of City Planning, Primary Land Use Tax Lot Output (PLUTO) (64uk-42ks), accessed Sep 15, 2026. They describe the tax lot, not any single filing. When the rest of New York went up
