Most likely yes. Ev charger installation usually requires a permit in Missouri. Confirm the specifics with Unincorporated Howell County.
A new 240-volt circuit, outlet, or hardwired charger is new electrical work; where the city or county has adopted an electrical code, expect to need a permit, which comes from the local government, not the state. Missouri has no statewide electrical permit or inspection program; electrical permits come from the city or county, and a local government must accept the optional statewide electrical contractor license in place of its own (RSMo 324.925). Whether a homeowner may do their own electrical work is a local rule; Missouri has no statewide homeowner electrical exemption. Many rural Missouri counties have not adopted a county building code, and a county code applies only outside city limits; inside a city, the city's own code governs. This installation adds a 240-volt circuit or a hardwired charger, or changes the electrical panel. New circuits and panel work are electrical work that normally needs an electrical permit and inspection wherever an electrical permit program exists. A panel upgrade or new service usually also involves your electric utility, which may need to disconnect and reconnect power, so call them early. Many places require a licensed electrician for this work. Where a homeowner may do their own wiring, the permit and inspection still apply.
