About this record

Opens the county's own page for this place.

Most people don't know what a normal result looks like for a place that's open every day. The ranges use each place's last routine inspection in this area. No other county is mixed in.

100 means the inspector found no problems. Santa Clara County takes points off for each problem. Big ones take off more.

The county posts a green, yellow or red placard after each inspection, and gives routine inspections a score. In the county's data, a routine inspection with no violations listed scored 100, and the score drops as violations are found. The county's page does not say which scores or findings give each color: ask the department.
