## Method and limits

Open cases are those with status In Violation, In Violation - Court, Under Investigation, or a balance due. Vacant and unsafe are matched on violation code titles. Tax owed sums every open tax period with a positive balance. Owners are kept only when both owner fields are organizations by legal-form and entity words; mailing addresses are not carried.

Not a list of individual homeowners (excluded) and not a determination of liability. L&I fee amounts are not in the open data, so the balance-due count marks the cases, not the dollars.
