Why knob-and-tube wiring replacement comes up in Paterson
Paterson's two- and three-family houses in Eastside Park, Riverside and the neighborhoods around the Great Falls were built in the late 1800s and early 1900s, when the city was America's silk capital, and knob-and-tube wiring is still found in many of them. Multi-family homes are usually rewired one unit at a time. In flood-prone areas near the Passaic, rewiring is a good time to move panels and outlets higher.
Eastside Park is a historic district. Permits come from the city's construction office, New Jersey requires a licensed electrical contractor, and PSE&G coordinates service changes.

Knob-and-Tube Wiring Replacement in Paterson: questions
Do I need a permit for knob-and-tube wiring replacement in Paterson?
Usually, yes. Electrical permits come from the city's construction office under New Jersey's Uniform Construction Code. New Jersey licenses electrical contractors through the Board of Examiners of Electrical Contractors. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Paterson?
If the work affects the meter or service, the electrician coordinates with PSE&G, 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.
