Similar to a number of western states, the state, cities and counties in Arizona play a significant role in licensing and regulating. Cities often take care of some of the most local issues like valet parking, while counties manage health permitting, particularly food businesses. Arizona itself oversees many industries, particularly professions and businesses that affect public safety.
In Arizona, as the name suggests, auto repair businesses fix cars, trucks and other motorized vehicles. Although a few states such as Texas, have no special licensing requirements to work on cars, most states and some cities and counties require auto mechanics and their businesses to be duly licensed. In California, an auto mechanic may need a professional license, state license to run a repair shop, county auto repair permit, county HAZMAT permits and a city business license. Regulations vary from state to state.
