REFERENCE / 01 / METHOD & SOURCES
Public ingredients.
Accountable files.
The records.
Philadelphia L&I code violations document cited conditions and city case identifiers. Philadelphia OPA property records supply property and owner facts. The City’s ZIP polygons supply this preview’s map geometry.
The matching.
The locked pipeline requires one property record per normalized address. New signals append to the existing history. ZIP tiers count distinct properties, not signals. Hot-property counts are tracked separately.
The interpretation.
Heat bands identify stacked signals and unsafe designations. Distress scores describe distress, not lead quality. Demo-risk and teardown flags keep likely demo/investor opportunities out of restoration delivery. Owner records support a suggested first move; they do not establish permission to contact anyone.
The ingredients are public — the weighting, thresholds, and matching are ours.
The ZIP tiers.
Composite rank is the average of distress-volume rank and home-value rank across 35 ZIPs. Ranks 1–12 are Prime ($150/ZIP/month), 13–24 Standard ($100), 25–35 Emerging ($50). Re-scoring is scheduled for January 1, April 1, July 1, October 1. Subscriber tiers lock at signup.
Dates and freshness.
This preview uses a historical L&I extract through 06 OCT 2026, pulled 10 OCT 2026, and a territory source dated 16 OCT 2026. L&I and OPA live syncs are not connected. No operational refresh cadence or posting-to-delivery latency has been verified. The 7:00 AM Eastern digest is a delivery schedule, not a claim about source freshness.
What remains unverified.
The brief’s 35-ZIP total conflicts with its 36 listed ZIPs. Actual ranks, tiers, prices per named ZIP, and availability are not supplied. No current delivery ledger, enrichment operation, billing connection, or intake endpoint is demonstrated by this preview.
