The local numbers
How old the wiring is likely to be in Edgerton
Of the 2,517 homes in Edgerton, 592 date from 1939 or earlier, 23.5% of the total (Rock County: 19.2%). Knob-and-tube wiring was in common use from about 1880 into the 1940s, so those are the houses where it can still turn up behind plaster or in the attic. It ranks 4th of 5 here.
647 homes in Edgerton (25.7%) were built from 1960 through 1979, close to the county's 27.7%. The CPSC says cable installed from 1965 to the mid 1970s may have aluminum branch wiring, so in that slice of the housing it is worth a look at the cable markings before adding outlets or a bigger panel (aluminum wiring). It ranks 2nd of 5 here.
Edgerton's median year built is 1969 (county 1970), and 38.9% went up before 1960. Many of the newer subdivisions already have 100- or 200-amp service, so the common jobs are added circuits, EV chargers and generators more than full service changes. It ranks 2nd of 5 here.
Wiring eras: InterNACHI on knob-and-tube; U.S. CPSC on aluminum wiring.

Local rules
Electrical permits and power in Edgerton
Edgerton's electrical fees and power company were not on a city page we could read; City Hall can confirm both.
- Permits and inspection
- Edgerton's building code (chapter 192) gives the city jurisdiction over replacing major building equipment, electrical systems included, calls for plan review and on-site inspections of one- and two-family homes and commercial buildings by inspectors certified by the state Department of Safety and Professional Services, and uses the Wisconsin uniform building permit. source
Where Edgerton publishes less, the state rules still apply everywhere in Wisconsin: electrical work has to be done by a licensed electrician unless you own and live in the house, and a new service, feeder or branch circuit needs a permit before work starts. How that plays out in Janesville is in the Janesville permit guide, and what a homeowner may do alone is in can you do your own electrical work.
