You also have to make sure that the house is zoned for a business. If it is zoned residential, you probably would NOT be able to convert the house for commercial use. But if it is zoned commercial or commercial/residential then you can. At least that is the way it is here in Memphis.

You can't just take a house and turn it into a business without the proper permits/zoning. So check it out with your local permits/licensing offices.
