Questions this answers
5 · best fit firstThe anonymous official SODA product returns address/property-group-keyed violations with authority code, description and ordinance, violation/status dates, inspection context, and OPEN/COMPLIED/NO ENTRY disposition. Records are historical/informational; absence is not a pass and property groups may span buildings.
Exact authority tuples identify smoke-detector installation/relocation requirements, defective or out-of-service detectors, activated closing devices, and fire-pump monitoring requirements with finding date and status. They do not provide complete system inventory, coverage, monitoring arrangement, current operability, or compliant absence.
Exact authority tuples identify sprinkler, pump and standpipe repair/operation findings and an annual fire-pump test requirement with violation/status dates. They do not prove passed tests, complete history, active impairment, correction, or current operability.
Official code tuples classify dated repair findings for exterior walls, parapets, roofs, and stairs, with inspection context, comments, status, and dates. This is defect-only authority evidence, not complete or current exterior condition, and lot ambiguity remains.
An exact roof-defect repair code is emitted with date, inspection context, comments, and authority status. A returned roof violation is useful dated defect evidence; no result is not sound-condition evidence and the record does not prove repair or current condition.
