Building details

Present-day data · provided by prospect.nyc. These figures describe the lot today, not in 2001 — building facts only, never owner names, unit lists or sales.

Tests over time

Each dot is a day on which a test candidate page names that substance for this building; bigger dots mean more pages that day. Dates and substances are machine-extracted from the page, and a dot is a page, not a result.

Samples, readings and decisions over time

Candidates extracted by machine can misread scans. Dates, substances, values and labs below occur on the same page; their relationship is not established — a value shown is a number found on the page, not a confirmed reading. Verify the page.
