Knob and Tube Wiring Replacement FAQs – Yosemite National Park

Is knob and tube illegal?

Existing wiring is allowed in many areas, but it cannot be extended and insurers often refuse to cover it.

No. Covering knob and tube with insulation is a fire hazard and a code violation.

We fish new cable through existing paths and make small, patchable openings.
