This is an on-demand research service, not a preloaded citywide inventory. Your verified account can request supported records for a new property. Successful evidence is saved and reused; unavailable sources remain visible. Parcel count does not mean every source has records for every parcel. The latest publication is a catalog-wide date; check each report's source timestamps for its freshness. See the data catalog.

What you get after a search

Every search opens one workspace for that tax lot. Records are grouped by the public source they came from, each row links back to the official record, and categories with no matching records or no published coverage stay visible instead of being quietly dropped.

Demonstration tax lot · BBL and BIN shown here

Demonstration data

  • Approved permit

    DOB NOW Approved Permits · Work type and applicant appear on the record

    record returned

  • Open violation

    HPD Violations · Class, status, and inspection date appear on the record

    record returned

  • No matching rows

    DOB Safety Violations · The source answered and returned nothing for this lot

    no records

  • Not covered

    ACRIS Recorded Documents · No evidence is published for this category; nothing is concluded from the gap

    not covered
Each row keeps the source it came from and the time it was retrieved, and opens the official NYC record. A source that returns no rows is not evidence of compliance, safety, or legality — and missing coverage is recorded as a gap, never as a clean result.

Where records appear

Permits, violations, complaints, zoning, and ownership records for the parcel land in the workspace tabs above. Neighborhood context stays in its own section.

How to follow the evidence

Open any record to see its raw source fields, the retrieval time, and a link to the official NYC dataset it came from.

How gaps are shown

A coverage ledger reports each category as available, empty, stale, conflicting, or not covered, so a partial dossier is never presented as complete.
