House Rewiring Cost: What to Budget
Rewiring costs vary more with access and finishes than with wire. Here's how to think about the budget.
Updated 2026-10-15
Typical ranges
Planning ranges of roughly $3–$8 per square foot are common for whole-house rewiring, with plaster-and-lath homes, multi-story layouts, and high-cost metros at the upper end or beyond. A panel upgrade, if needed, is usually priced separately.
What drives the number
The biggest factors:
- Wall type: drywall vs plaster and lath
- Access from attic and basement or crawl space
- Number of circuits, devices, and fixtures
- Panel and service upgrades
- Wall and ceiling repair (often by another trade)
- Permits and multiple inspections
Phasing to manage cost
Rewire the kitchen and baths during their remodel, then tackle remaining rooms later. Ask the electrician to install a panel with enough spaces for the eventual full scope so you're not paying twice.

Frequently asked questions
Does a rewire include drywall repair?
Often not. Many electricians make access holes and leave patching to a drywall contractor. Confirm in the quote.
Can I reduce cost by opening walls myself?
Sometimes. Discuss it with the electrician first so openings are where they need them.
Is rewiring covered by insurance?
Typically not, unless it's repair after a covered event like a fire.
