Import property records and resolve the legal jurisdiction independently of the mailing address.
THE PROPERTY LAW PASSPORT / DEMO EDITION
ONE ADDRESS.
RULES WITH PROOF.
The rental-law answer for a building—what applies, what changes, what source proves it, and what we still need to know.
THE LIVE JUDGE WALKTHROUGH
FOUR CLICKS.
ONE ENGINE.
Use the guided path to show uncertainty, jurisdiction, effective dates, and portfolio-wide change. Each card opens the real output—not a mock screen.
SEARCH THE SUPPLIED DATA
FIND A BUILDING.
SEE THE PROOF.
Search by sample ID, street or city. Every answer is tied to a date and source.
Choose a result to open its passport. Press Enter to open the first match.
Dates outside the captured challenge period require new source review. Earlier snapshots of amended laws are not available.
FROM DEMO TO OPERATION
One operator action at a time.
Search a building, see the conditional answer, verify the named fact, and re-evaluate. The 500 records test that workflow; they are not 20 million legally verified passports.
Check the highlighted missing building fact with a responsible source; do not silently guess.
Apply reviewed rules by jurisdiction and date; show citations and unresolved conditions.
Monitor official sources, send changes to expert review, then recompute affected homes.
Scale path, measured: the indexed data pipeline imported 20 million synthetic property rows in 133.5 seconds. Production still needs source monitoring, expert review, parcel boundaries, and verified property facts.
