What this can establish
- Which exact NYC tax lot the checked identifiers support.
- Which addresses or building identifiers were observed for that lot in the admitted sources.

Resolve one NYC property without guessing
Understand why PropSignal routes by one exact tax lot while keeping multiple addresses and building identifiers visible.
How does an address or BIN become one property page?
This guide describes the deterministic identity boundary used by Search and canonical property pages.
How PropSignal reads it
- Normalize the submitted address, BBL, or observed BIN without replacing the original meaning.
- Resolve candidates through source-reported parcel and building identifiers.
- Open a canonical property page only after one parcel is established; otherwise return explicit candidates, ambiguity, or no result.
- Preserve one-lot/multiple-building and multiple-address relationships instead of collapsing them.

What this does not establish
- That a nearby or similarly written address is the intended property.
- Legal occupancy, ownership, unit count, or current physical condition.
Dates and missing evidence
- Date meaning
- Identity evidence retains its source release and retrieval time. Later corrections create lineage; they do not silently rewrite the earlier identity result.
- When evidence is missing
- An unresolved or ambiguous identifier means the checked evidence did not establish one parcel. It is never converted to a nearest-address match.
