How much does it cost to rewire a house per square foot?

House rewiring is usually priced per project, not per square foot, and Big Family lists $8,000–$15,000 for an average-sized home. The biggest price swing comes from your home’s layout and the code-driven scope of work needed for a safe system. Per‑square‑foot math can mislead because fixed tasks like safety upgrades and inspections don’t scale evenly with size; a 1,200‑sf home with a panel change can price like a larger home without one. In our Baton Rouge area, hot attics often influence labor planning and the type of wire we use. Final pricing is confirmed after an on‑site electrical inspection.

If you want a sense of why bids vary, contractors consider:

• Overall square footage and number of circuits
• Access to existing wiring (attic, walls, crawlspaces)
• Panel upgrades, plus GFCI/AFCI and grounding updates
• Drywall patching and finish level after access cuts
