Method and limits

Read SCO value bands 3 ($100 to $499) and 4 ($500+) from the all-records download. Keep owners whose name carries an organization marker (LLC, INC, CORP, BANK, DISTRICT, COUNTY OF, HOSPITAL, UNIVERSITY and similar). Drop names with person or fiduciary markers (FBO, C/O, ESTATE, TRUST, TRUSTEE, CUST, IRA, DBA, UTMA) so individuals and family trusts stay out, and drop rows where the holder lists itself as owner. Multi-owner properties collapse to one row. Owner names are normalized and matched to Tensorust Ontology organizations.

Not a list of individuals: person and trust owners are excluded on purpose. Not a claim service: Tensorust does not file claims or act as an investigator or finder. Not other states (California publishes amounts in bulk). Name matching is heuristic; an ontology match is a lead, not proof the property belongs to that organization. Properties under $100 are left out.
