How a business gets listed
- Licence pulled from the boardWe read each state's register (Arizona ROC, CSLB) for the licence classes every trade needs.
- Only active licencesSuspended, expired and revoked licences are counted on city pages but never listed.
- Public records addedBond and workers' comp, board disclosures, building permits, EPA lead-safe status, Google rating, reviews and photos, and the business's own website. Each fact names its source and date.
- Ranked by a published formulaYears licensed, complaint record, bond and insurance, and reviews. Claiming a listing or paying never changes the order.
