Usually, yes. Electrical permits in Toledo come from the city's Division of Building Inspection; surrounding communities issue their own. Ohio licenses electrical contractors through the Ohio Construction Industry Licensing Board. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Toledo?
If the work affects the meter or service, the electrician coordinates with Toledo Edison (FirstEnergy), which owns the meter and service drop.
Is knob-and-tube wiring illegal?
Existing knob-and-tube is generally not illegal, but it cannot be extended, and many insurers and lenders treat it as a reason to replace.
Can knob-and-tube be insulated over?
It is not recommended, and many codes and insulation programs prohibit it, because the wiring relies on open air to cool.
