Missouri has no statewide residential building code, so the rules in Unincorporated Newton County come from whichever city or county code covers the address. Cities adopt and enforce their own codes, and a county may adopt a code for its unincorporated area only under RSMo 64.170, which since 2001 has required voter approval for counties without a prior code. Many rural counties have no county building code, and in those areas no state agency issues residential building permits in its place, although floodplain, utility, septic, and propane rules can still apply. There is no statewide dollar or size exemption from permits. Confirm the rules for Unincorporated Newton County with the city or county building office that has jurisdiction before starting work.
