Do I need a permit for standby generator installation in Unincorporated Caldwell County?
Most likely yes. Standby generator installation usually requires a permit in Missouri. Confirm the specifics with Unincorporated Caldwell County.
Propane tanks and piping must meet Missouri Propane Safety Commission rules, which follow NFPA standards under RSMo 323.020, and a county building code may not conflict with them (RSMo 64.196). A transfer switch is required to keep a generator from back-feeding utility lines; the local electrical code sets the details. Missouri has no statewide residential building code; whether a permit is required depends entirely on the city or county code that covers the address. Missouri has no statewide homeowner electrical exemption; any owner exemption is local.
Local detail for Unincorporated Caldwell County: Caldwell County issues a permit under its county zoning rules, but has not adopted a residential building code for unincorporated areas, so the work may not be inspected to a building code. Ask the office what the permit covers and whether any inspections apply.
