Why knob-and-tube wiring replacement comes up in Richmond
Rowhouses in the Fan, Church Hill, Jackson Ward and the Museum District were built from the 1880s to the 1920s, and knob-and-tube wiring still runs through many of them, often spliced into circuits added when houses were split into apartments. Shared brick party walls limit routes, so electricians work through floors, basements and attics, usually floor by floor. Several of these neighborhoods are old and historic districts with exterior review.
Insurers often ask about knob-and-tube. Permits come from the City of Richmond's permits and inspections office, and Dominion Energy Virginia coordinates service work.

Knob-and-Tube Wiring Replacement in Richmond: questions
Do I need a permit for knob-and-tube wiring replacement in Richmond?
Usually, yes. Inside the city, electrical permits come from the City of Richmond's permits and inspections office; Henrico and Chesterfield counties issue their own. Virginia licenses electricians and contractors through the Department of Professional and Occupational Regulation (DPOR). The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Richmond?
If the work affects the meter or service, the electrician coordinates with Dominion Energy Virginia, 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.
