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

Rewiring a house is not reliably priced per square foot; electricians price it by scope after an on-site inspection. Most costs come from labor to replace circuits and bring the system up to current code, not from the home’s size alone. In practice, footage matters less than circuit count and how easily new cable can be fished through finished walls. Across Brevard County homes, rewiring is commonly coordinated with broader electrical modernization to handle today’s loads.

Key drivers that change the price:

• Whole-house vs partial scope (like a kitchen remodel) and whether walls are open or finished
• Aluminum-to-copper conversions or knob-and-tube replacement requiring added safety work
• Panel, meter, or fuse-to-breaker upgrades for capacity and compliance (100A–400A options)
• Add-ons such as whole-home surge protection or backup generator integration

Request a licensed electrician’s assessment to confirm circuits, panel capacity, and timeline before you decide to repair, replace, or phase the work.
