Where in town am I allowed to run a short-term rental?

 R2 or Commercial zoning. Refer to the property zoning map. https://jonesanddemille.maps.arcgis.com/apps/webappviewer/index.html?id=3ce4b153ee92459aad05d9a7faaf9ad9

If you are to do a short-term rental you will need a business license for short/long-term business license and fire inspection. The fire inspection can be set up by calling Monticello City Office (435) 587-2271
