A road side stand may include a person's home. I would think a simple sign would be enough to qualify as a road side stand. Many of the road side stands that you see for garden produce in the summer are just a sign and a card table.
As far as health inspections, unless the county itself institutes regulations, it would seem that you would be inspected by the state only if there was some problem with your products.
(c) An individual vendor who meets the requirements in subsection (b) is subject to food sampling and inspection if:
(1) the state department determines that the individual vendor's food product is:
(A) misbranded under section 12(b) of this chapter; or
(B) adulterated; or
(2) a consumer complaint has been received by the state department.
(d) If the state department has reason to believe that an imminent health hazard exists with respect to an individual vendor's food product, the state department may order cessation of production and sale of the food product until the state department determines that the hazardous situation has been addressed.
(e) For purposes of this section, the state health commissioner or the commissioner's authorized representatives may take samples for analysis and conduct examinations and investigations through any officers or employees under the state health commissioner's supervision. Those officers and employees may enter, at reasonable times, the facilities of an individual vendor and inspect any food products in those places and all pertinent equipment, materials, containers, and labeling.
Also the state health commisssioner is supposed to publish guidelines for home producers.
The state health commissioner may develop guidelines for an individual vendor who seeks an exemption from regulation as a food establishment as described in subsection (b). The guidelines may include:
(1) standards for best safe food handling practices;
(2) disease control measures; and
(3) standards for potable water sources.
