No commercial aeronautical activity shall be conducted by any person at the airport without said person being in possession of a valid aeronautical business permit. Each person holding an aeronautical business permit must hold a valid and current business or privilege tax license issued by the city if such license is required by the city. Issuance of an aeronautical business permit does not entitle the holder to possess, occupy or exclusively use any portion of the airport, grant any exclusive right to conduct any business or activity, or authorize any conduct prohibited by zoning regulations or any other applicable law.
