Collin County permits
Building permits from every city in Collin County, as the Collin Central Appraisal District records them: the city, the work, the builder and the ZIP. Cities report to the district monthly, so the last few weeks fill in late — a dip at the right edge is lag.

How this stream is checked
- Pulled straight from Collin Central Appraisal District — no reseller in between — and compared against that file before it is served.
- Null means the source did not report it — never zero.
- A reading lands daily; the interval timestamp is the start of the interval, in UTC.
- The people are not stored. Contractor and applicant names, phones and addresses are never selected; the contractor company is kept, because which firms pull permits where is the point of the feed.
