About this record
The city's open data lists each violation with the department's standard wording. The inspector's own notes are in the report on the department's lookup: search for the name.
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.
San Francisco gives each inspection a result, not a score, so there is no typical range to show.
San Francisco posts a green, yellow or red placard after each inspection. Green, Pass: zero to 1 major violations at the inspection. Yellow, Conditional Pass: 2 or more major violations, corrected at the inspection, and a reinspection follows. Red, Closure: health hazards or major violations that can't be fixed right away. There is no score or letter grade.
