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

The cost to rewire a house per square foot is only accurate after an on-site inspection because conditions vary from home to home. The biggest factor is how easily we can access and replace existing wiring while bringing everything up to current electrical code. Our licensed team performs these assessments across the Norris area and provides detailed estimates up front. In older homes, more time often goes into tracing hidden junctions than pulling new cable, which changes unit pricing.

What affects per‑sq‑ft pricing:

• Access to attics/crawlspaces and wall material that impacts opening and patching
• Panel capacity and whether a panel upgrade is required
• Required GFCI/AFCI protection and smoke alarm interconnection to meet code
• Occupied versus vacant conditions and finish‑protection needs
• Local permitting and inspection scope
• Partial rewire versus whole‑home, plus add‑ons like lighting or EV chargers
