Credentials differ by state and city, because the requirement itself does. Each listing says which one it holds.

This is a credential, not a trade. Every state’s general-contractor or builder licence, home-improvement registration and city building-permit history lands here, so a firm listed as a general contractor may frame houses or fit bathrooms. The listing shows exactly which credential it holds; the profile shows what it does.

Ordered by permits pulled, so businesses with a verified record of inspected work come first.

Badges come from public records, not from us or the business. Licence verified: an issued licence number and a city permit record name the same firm. Established: ten or more permits on record. Active this year: a permit dated in the last 12 months. A business without a badge may simply work where we hold no permit records.

These businesses pulled permits that Boulder County recorded, but the permit records do not establish which trade they work in, so we do not file them under one. Ask what they do before you ask for a quote.
