The Clark County Department of Business License has the authority to investigate complaints regarding licensed and unlicensed businesses in the unincorporated area of Clark County. This authority generally relates to a determination of whether a business has a Clark County business license and whether that license is the proper license for the business activities being conducted.

The Department on the other hand has no jurisdiction to investigate alleged criminal activities, the general business practices of a business, quality of workmanship, pricing of goods and services, monies owed, hours of business operation, and/or of the availability of a business operator to respond to complaints.
