How permitting works in Missouri
In Missouri, the county's role is strictly limited by its legal "class." Only First and Second-class counties (typically the most populated) have the inherent authority to issue building permits; for the rest of the state, the county has no role in structural permitting, leaving the task entirely to incorporated cities.
Limited to specific County classes; Cities dominant.
