Coverage: Boulder, Jefferson, Adams, Arapahoe and Douglas counties, 5 of 64 counties. All sources
Adams, Arapahoe and Douglas counties: Tri-County Health Department restaurant inspections from the Colorado Information Marketplace (data.colorado.gov), public domain. GradeLocal counts the violation items marked on the latest inspection: 0 is an A, 1 to 2 is a B, 3 to 5 is a C, and 6 or more is a D. Tri-County Health Department closed at the end of 2022, so these results are from 2019 to 2022.
What Colorado publishes
The agencies behind our Colorado listings publish pass or fail results and violation counts. None of them publish a score out of 100, so every Colorado score on GradeLocal is a GradeLocal score, worked out from the official result.
How GradeLocal grades Colorado restaurants
For pass or fail results, a pass is an A, a pass with conditions or a required reinspection is a C, and a fail or a closure is a D. A pass that lists violations, such as “Pass (2 violations)”, is graded on the violation count instead.
For violation counts, we count every violation in the latest inspection. None is an A, 1 or 2 is a B, 3 to 5 is a C, and 6 or more is a D. An emergency closure order is also a D.
Results with no score of their own get a set score for each letter: A is 95, B is 85, C is 72 and D is 50.
There are four letters, A to D, with no F. The same rule applies in every state, and the cutoffs are never adjusted for a state, county or city. We always use the latest inspection.
