The only state in the Union with Napoleonic Code and parishes instead of counties has always been a little different thanks to its French roots. However, today's Louisiana has similar business licenses and permits to other states. In fact, it regulates significantly at the state level while even New Orleans, its largest city, remains light on licenses and permits.
In Louisiana, any business that serves food can endanger public health. That’s why restaurants are some of the most regulated businesses out there. Multiple state, county and city environmental health permits are common for restaurants. Those that serve alcohol need even more licensing. Prospective restaurateurs should expect to apply for at least five licenses and permits and in many cases much more.
