Do I need a permit for standby generator installation in Unincorporated Benton County?

The requirements below come from Missouri rules. They are not a statement that Unincorporated Benton County issues or does not issue permits.

Permit likely required

Most likely yes. Standby generator installation usually requires a permit in Missouri. Confirm the specifics with Unincorporated Benton 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.
