The mountainous state of Colorado shares regulatory responsibilities with its counties and cities. While Colorado oversees many major industries such as healthcare, counties license health and food and cities frequently regulate local issues such home businesses. Colorado's centralized licensing system makes obtaining state-level licenses easy and efficient.
In Colorado, smog or emission check facilities are common in states with tight air pollution controls. States like California and New York allow facilities that are not auto repair businesses to perform emission tests and issue official reports required for vehicle licensing and renewal. Emissions testing shops must hold special state licenses and in some cases, licensing agreements to operate their computer systems.
