Do I Need a Permit for Whole-House Rewiring? in Polen
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. Unpermitted rewiring can void homeowner's insurance and is a red flag in home sales.
