Key takeaways

Rewiring usually costs $3 to $5 a square foot of home on HomeAdvisor's numbers and $3 to $6 on Fixr's.
HomeAdvisor puts a 2,000 square foot house at $6,000 to $10,000.
A panel upgrade, permits and inspections are separate lines that add up.
Opening and patching walls is part of the job; plaster walls take longer.

Rewiring cost by home size

Home	Fixr
700 sq ft	$2,318 to $4,218
1,000 sq ft	$3,312 to $6,026
1,700 sq ft	$5,630 to $10,244
2,200 sq ft	$7,286 to $13,257
3,000 sq ft	$9,936 to $18,078

The calculator uses the middle of HomeAdvisor's $3 to $5 and Fixr's $3 to $6 a square foot.

Rough-in and new construction

HomeAdvisor says wiring a new home costs $3 to $5 a square foot and the electrical rough-in alone $2 to $4, because walls are open. Rewiring an old home costs more for the same wire because of the opening and patching.

Panel, permits and inspections

HomeAdvisor puts permits at $250 to $900 and inspections at $150 to $250. A rewire often goes with a panel upgrade; the calculator uses the panel cost guide's combined $1,300 to $3,000.

A worked example

Rewiring a 2,000 square foot home at the US average comes to $6,000 to $11,000, about $8,500 typical. With a panel upgrade and permits, about $11,225. Enter a ZIP to scale the 65% labor share.
