Steps
Dataset f29f-zza5, 'Food Establishment Inspection Data', covers King County Environmental Health inspections from 2006 to present, one row per business/inspection date/violation
Query https://data.kingcounty.gov/resource/f29f-zza5.json with $where on name or business_id, plus an inspection_date range
Read inspection_result and grade for the outcome, and violation_points for severity; description often encodes seating count and risk category text
Group rows by inspection_serial_num to reconstruct all violations belonging to a single inspection visit
Known gotchas
Multiple rows share the same inspection_serial_num when an inspection cites multiple violations - summing violation_points or counting rows without grouping by serial number overcounts inspections
King County was mid-transition to a new permitting system as of late 2025 per the dataset's own notes, so recent months may show a gap or format shift
