Before you move a slider, the list is in a default order built only from the permit record: how much of each firm’s record is this kind of job (weight 30), how often its permits reached completion (25), how many permits it filed in the last 12 months (15) and how quickly its permits closed (10). Each measure is ranked against the other 53 firms and pulled toward the middle when a record is short; a firm with a matched license problem is listed last.
The order comes from the Boulder permit file, not from reviews: 20 of 53 home builders filed a permit in the last 12 months and 68% of their permits a year or more old were finished.
