Breaking Down How Much It Costs to Rewire a Whole House

Here’s the question every homeowner eventually asks: how much does it cost to have a house rewired? The honest answer is that no two projects are priced the same — but the factors that drive the number are very consistent, and that’s what this guide covers. What’s not up for debate is whether it’s worth doing — outdated wiring is one of the leading causes of residential electrical fires in the US, and ignoring the signs rarely ends well.

According to HomeGuide, the average cost to rewire a whole house starts from $10,000, scaling up with square footage, accessibility, and system complexity. Forbes puts average projects starting from $1,100 for smaller scopes, while SoFi reports rewiring typically starts from $6 per square foot for full projects. So if you’re still wondering how much does it cost to have a house rewired end-to-end — the range is wide, but the factors driving it are predictable.

Average Cost of Rewiring in the US

What is the average cost to rewire a house? For most homeowners, a full rewire starts from around $10,000. Labor alone runs $50–$100 per hour, and a complete project can take several days. Before signing anything, it helps to understand how much does it cost to have a house rewired in your specific area — California rates, including Monterey County, typically run at the higher end of national averages.

Robert Dietz, Chief Economist at the National Association of Home Builders, points out that skilled trade shortages are pushing baseline labor costs higher across all project sizes — rewiring included.

Permits add $300–$500 each, inspections run $100–$250, and the Fuse Monterey technicians serving Monterey County see similar numbers locally. Every quote should include diagnostics, permitting, and a clear scope — if it doesn’t, ask.

Cost Breakdown by House Size

Square footage is the most direct pricing driver. Here’s what to expect when asking how much does it cost to rewire a whole house based on size:

These figures cover labor and materials. They don’t automatically include panel upgrades, drywall repair, or dedicated circuits — all of which add to the total.

Key Factors That Affect Rewiring Costs

Size and Age of the House

Older homes cost more to rewire — full stop. Anything built before 1980 tends to come with knob-and-tube or aluminum wiring, walls that weren’t designed for modern access, and systems that need replacing from scratch rather than patching. What does it cost to rewire a house like that? More than the initial quote usually suggests — our Fuse Monterey installers have opened walls expecting a two-day job and found a week’s worth of work waiting inside.

Labor Costs and Local Rates

Labor typically accounts for 50–70% of the total project cost. Electricians charge $50–$100 per hour nationally, though rates in California — including Monterey County — trend toward the higher end. A full rewire takes multiple days, sometimes a week for larger homes. That’s why what does it cost to rewire a house varies so much between ZIP codes, and why what is the average cost to rewire a house is almost impossible to answer without knowing the location.

If you’re already dealing with common electrical problems at home like flickering lights or tripping breakers, the labor scope often expands beyond wiring alone.

Materials and Type of Wiring

Copper wiring, modern panels, and GFCI/AFCI outlets are the current standard — and they cost more than older alternatives. But they’re also what meets code and what insurance companies want to see. The cost to install electrical wiring gives a detailed breakdown of what individual components add to the total.

Additional Costs to Consider

Electrical Panel Upgrades

Most older homes run a 60-amp panel — modern living needs at least 150 or 200 amps. Panel replacement starts from around $1,300 and often gets bundled into rewiring projects. See the full breakdown in our guide on how much it costs to install an electrical panel.

Opening Walls and Structural Work

This is the cost that surprises people most. When wiring runs through finished walls, technicians cut access holes, fish new wire through, and the homeowner handles drywall repair and repainting afterward. That extra work adds 25–30% to the project total. If you’re doing a renovation anyway, scheduling a rewire at the same time cuts this significantly — walls are already open.

Signs Your Home May Need Rewiring

Not sure if a full rewire is actually necessary? Watch for:

• Lights flickering or going dim the moment a large appliance starts up
• Circuit breakers that trip repeatedly
• Burning smell or warm outlets
• Two-prong ungrounded outlets throughout the home
• Wiring that hasn’t been touched since before 1980

These are the issues the electricians in Salinas at Fuse Monterey run into constantly — and they rarely fix themselves. Left alone, they become more expensive problems.

Frequently Asked Questions

How long does it take to rewire a house?

Realistically? It varies from three days to a week and a half. Smaller homes with accessible wiring move fast. Older homes with finished walls, tight crawlspaces, or a panel upgrade thrown in — that’s where the timeline stretches. The estimated cost to rewire a house and the schedule both come into focus after someone actually walks through the property.

What does it cost to rewire a house room by room?

Kitchens start from around $1,000 and climb fast — dedicated circuits and GFCI requirements add up. The awkward truth is that partial rewiring gets less and less economical the more rooms you add. Permits, wall access, mobilization — you’re paying for all of it regardless. Four rooms in, a full rewire usually wins on price.

How Much Does It Cost to Rewire a Whole House With Wall Access Issues?

When asking how much does it cost to rewire a whole house with finished walls, add 25–30% to your baseline estimate. A project running from $10,000 with accessible wiring can reach $13,000 or more when drywall needs cutting. The estimated cost to rewire a house almost always surprises people on this point — scheduling the rewire alongside other renovation work is the simplest way to reduce it.
