The birthplace of country and blues has become far more than the agrarian state it once was. Tennessee's major urban centers are important cities with significant economies. And Tennessee fully supports economic growth and development -- which may be why it doesn't impose too much regulation on business. Unlike many states, Tennessee gives counties and cities significant leeway to decide on their own regulations -- often making state licenses required only at the discretion of local jurisdictions.
In Tennessee, bakeries are typically regulated by county and city environmental health authorities. However, the licenses and permits required vary widely. In some places, licenses specific to bakeries apply, while in others bakeries are treated like other retail food establishments. However, in all cases, bakeries and other food sellers must have one or even several food safety licenses.
