For contractors with at least 5 permits a year or more old, the share that passed final inspection. A permit can stay open because of paperwork or timing, so this isn't a workmanship grade.
How long their permits take from issue to completion, using the city's dates, compared with other Boulder contractors in the trade. Shown for firms with 10+ permits.
Matched by name against the City of Boulder's licensed contractors list. Name matching can miss a license, so always check the number yourself.
About the ranking: The score combines how much of this exact work a contractor has on record, how often their older permits reached completion (where we can measure it), how well their usual job size matches your budget, how recently they've been active, and how much of their work is near you. A measure we can't calculate is left out rather than guessed, and a thin record pulls the score toward the middle. A contractor whose matched license has a problem is listed after everyone else. You set the weights with the sliders on every list.
Boulder specifics: Permits that expire without an inspection count as not finished. The city's license list only holds current licenses, so a firm without a match may have let its license lapse.
