How Seattle grades restaurants
Public Health — Seattle & King County posts a word, not a letter: Excellent, Good, Okay, or Needs To Improve. The rating is deliberately not a snapshot — it averages the establishment’s recent routine inspections, so one bad day does not sink a consistently clean kitchen and one good day does not rescue a bad one. Inspectors score violations in red points for things that directly cause foodborne illness and blue points for everything else; around 45 red points triggers a mandatory re-inspection. Newly opened or recently changed spots can show as Not Rated until enough inspections accumulate.
