01 / Scope
What this source covers—and what it does not.
Known limit
One permit may appear at more than one address.
Coverage must be read from the source scope—not inferred from the city name.
02 / Handling01 02 03
How the private pilot handles this source.
Use the documented route
The pilot uses the documented socrata api and the source-specific request interval. It does not scrape an interactive portal or bypass access controls.
Filter before storage
Contact datasets are outside this pilot. Personal names, phone numbers, email addresses, and contractor home or mailing addresses are denied before durable storage.
Keep the source trail
Every accepted item must retain source ID sf_building_permits, its official URL, capture time, content hash, and raw-object location.
03 / Verify
Use the publisher for the current official record.
