Missouri rules that apply here

Building permitLimited

- A county that had not adopted a building code before August 28, 2001 needs voter approval, voted only by voters outside incorporated territory
- Municipalities and other counties must be checked locally
- This claim is about the county enabling authority only; the state septic rule (RSMo 701.031) was not used as a building-permit requirement
“the county commission in all counties of the first and second classification, as provided by law, is for this purpose empowered, subject to the provisions of subsections 2 and 3 of this section, to adopt by order or ordinance regulations to control the construction”
