Do I Need a Permit for Whole-House Rewiring? in Verenigde Staten
Whole-house rewiring almost always requires a permit in every market we operate in. The scope — opening walls, replacing circuits, and upgrading the panel — involves structural and fire-safety considerations that building codes require an inspector to verify.

Country-specific detail
Whole-house rewiring requires an electrical permit in every US jurisdiction. The scope typically means multiple inspections: rough-in inspection before walls are closed, and final inspection after devices are installed. Work must follow the National Electrical Code (NEC/NFPA 70) as adopted locally. Most jurisdictions require a licensed master electrician to pull the permit. Homes built before 1960 with knob-and-tube or pre-1972 with aluminum wiring are the most common candidates.
