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.
Being one of California and the nation’s major cities means San Diego is home to many businesses. However, the city’s licensing systems are fairly decentralized requiring business owners to apply to numerous departments including the city treasurer, planning and development and the police. Additionally, licenses from San Diego County, the state and sometimes the federal government are required in certain industries. San Diego's major industries include defense, international trade, shipping, tourism, manufacturing, research and real estate. The city's close proximity to Mexico and large natural harbor make it a gateway to commerce with Asia and Latin America.
