What is the purpose of a conditional use permit?

A conditional use permit (CUP) allows the county to consider uses that may be desirable to a particular community, but which are not routinely allowed, through a public hearing process, and to control certain uses which could have detrimental effects on a community or neighboring properties. A 'conditionally permitted use' on a specific property is subject to conditions that ensure compatibility with nearby land uses.

The conditional use permit process allows for consistent evaluation of land use applications and provides clear criteria on which to base a decision. The burden is on the applicant to provide adequate justification supporting a CUP request.
