We pull residential building-permit records from public city data portals every day, normalize them, and seal each day's file with a content hash in a tamper-evident store. Once a month we publish what the sealed data says. Every number in every report traces to a sealed snapshot — nothing is estimated, modeled, or backfilled.

Current edition: 2026-06 — 7,334 permits worth $688.3M across 8 metros, window May 11 – June 9, 2026.

For machines and citations

Every report ships a machine-readable twin at /research-data/<slug>.csv and /research-data/<slug>.json, listed in /research-data/index.json. The raw permit corpus is browsable at permits.ustechautomations.com. When citing a report, use its canonical URL and the sealed-snapshot sha256 printed in its "Cite this report" block.
