Knob-and-Tube Wiring Replacement in New Orleans, LA

Why knob-and-tube wiring replacement comes up in New Orleans
New Orleans shotguns, Creole cottages and Victorian doubles in Uptown, the Bywater, the Marigny, Mid-City and Treme often still carry knob-and-tube wiring, sometimes spliced into circuits added after Katrina. Humidity, termites and flooding are hard on old insulation. Raised homes give the electrician a route below the floor, and attics handle ceiling fixtures.
The Historic District Landmarks Commission and other review bodies regulate visible exterior changes. Permits come from the city's Department of Safety and Permits, and Entergy New Orleans coordinates service work. Ask for the rewire to be documented.

Knob-and-Tube Wiring Replacement in New Orleans: questions
Do I need a permit for knob-and-tube wiring replacement in New Orleans?
Usually, yes. Electrical permits in New Orleans are issued by the city's Department of Safety and Permits, and historic districts may need separate review for exterior changes. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in New Orleans?
If the work affects the meter or service, the electrician coordinates with Entergy New Orleans, 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?
An electrician can test it. Many homes have a mix of active and abandoned knob-and-tube.
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.
