NYC Property Timeline API and MCP server

No authnyc-property-timeline

One exact BBL timeline across ACRIS, DOB permits, HPD violations, and executed evictions.

NYC Property Timeline is published by NYC Open Data property-history datasets and covers New York City properties matched by exact ten-digit BBL.

It refreshes on a schedule the publisher sets.

Last verified . That is when these facts were last rebuilt from the ParcelOps source registry, not when NYC Open Data property-history datasets last refreshed the data itself.

What this source cannot tell you

  • ⚠ Anything outside New York City properties matched by exact ten-digit BBL. A request past that edge comes back empty rather than approximated.
  • ⚠ Which years it spans, because the covered period is not declared.
  • ⚠ Anything NYC Open Data property-history datasets does not publish. ParcelOps returns this source as it stands and never fills a blank field from a different one.
  • ⚠ The timeline can be incomplete or delayed and is not a title or lien search, legal opinion, appraisal, tenant screen, inspection, or proof of current code status.
  • ⚠ ParcelOps excludes party names, permittee and owner contacts, marshal names, court/docket identifiers, and apartment numbers.
