Do I need a permit for ev charger installation in Unincorporated Chippewa County?

Most likely yes. Ev charger installation usually requires a permit in Wisconsin. Confirm the specifics with Unincorporated Chippewa County.

As of Sept. 1, 2026, SPS 316.012 requires an electrical permit from the designated inspection agency before installing a new or added electrical service, feeder or branch circuit serving a structure not already covered by an SPS 316 or SPS 320 permit, unless exempted by rule or statute. Electrical work must be done by a state-licensed or registered electrician under a master electrician, except that a residential owner may wire premises the owner owns and occupies as a residence unless a local ordinance requires a license (Wis. Stat. 101.862(4)(a)). EV charging circuits and equipment fall under the Wisconsin Electrical Code, which adopts the 2023 National Electrical Code with state changes (SPS 316.007). Under SPS 316.013, wiring covered by a permit must stay exposed and not energized until inspected, unless the inspection has not been done within 2 business days after notice. 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.
