Usually, yes. Building and electrical permits for Memphis and unincorporated Shelby County come from Memphis and Shelby County Code Enforcement; suburbs such as Germantown and Bartlett have their own. Electricians must hold the license the jurisdiction requires. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Memphis?
If the work affects the meter or service, the electrician coordinates with Memphis Light, Gas and Water (MLGW), 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.
How do I know if mine is still live?

How long does replacement take?
From a few days for a small home with good access to a few weeks for larger plaster-walled homes.
