Before opening your business, you might need a county business license, and if you will be working within a city, a city business license. Businesses that perform work in several cities, such as builders, may need to obtain a license from each city in which they work. This does not have to be done until you actually begin to provide services in a particular city.
County business licenses can often be obtained from the tax collector or in the county courthouse. City licenses are usually available at city hall. Be sure to find out if zoning allows your type of business before buying or leasing property because the licensing departments will check the zoning before issuing your license.
