Key Takeaways
- A full rewiring project in California costs between $8,000 and $30,000, with most homeowners landing around $12,000 to $18,000.
- Home size is the single biggest factor; expect to pay roughly $6 to $10 per square foot for a full rewire in Orange County.
- Knob and tube wiring removal adds cost because it requires special permits and more labor hours.
- Bundling a panel upgrade with rewiring saves money compared to scheduling them separately.
- Licensed electricians pull the required permits, so the work passes inspection and protects your home insurance coverage.
Rewiring an entire house is one of the bigger investments an Orange County homeowner can make, and the cost breakdown for full house electrical rewiring surprises most people the first time they see an estimate. Understanding what drives those numbers puts you in control before you request a single quote.
What Does a Full House Electrical Rewire Actually Cost?
For most homes in Orange County and the broader Southern California area, a full rewire runs between $8,000 and $30,000. The average cost to rewire a 1,500-square-foot home sits closer to $10,000 to $15,000. A larger home of 2,500 square feet or more can push past $20,000 once permits, panel work, and wall repairs are included.
Here is a quick reference by home size:
| Home Size | Estimated Cost Range | Typical Timeline |
|---|---|---|
| Under 1,000 sq ft | $6,000 – $10,000 | 3 – 5 days |
| 1,000 – 1,500 sq ft | $8,000 – $15,000 | 5 – 7 days |
| 1,500 – 2,500 sq ft | $12,000 – $22,000 | 7 – 10 days |
| Over 2,500 sq ft | $20,000 – $30,000+ | 10 – 14 days |
These figures reflect California labor rates, which run higher than the national average. Nationally, the average cost to rewire lands around $10,000 to $17 per square foot. In Southern California, expect to pay toward the upper end of those ranges. For a deeper look at what goes into these estimates, see our guide on understanding the cost to rewire your home.
Why California costs run higher
A few factors push rewiring costs above the national average in this region:
- California electrical codes are stricter than in many other states, requiring more materials and inspection steps.
- Labor rates for licensed electricians in Orange County average $85 to $130 per hour, compared to $50 to $100 nationally.
- Fire-rated materials are often recommended here given Southern California’s wildfire risk.
- Permit fees in cities like Irvine, Anaheim, and Tustin can reach $500 to $1,000 for a full rewire.
The Four Biggest Cost Drivers in Any Rewiring Project
Understanding these four factors helps you know why two similar-sized homes can have very different quotes.
1. Labor costs
Labor costs make up 60 to 70 percent of a typical rewiring project. Most crews work at roughly one hour per 100 square feet of wiring installation, and full rewires almost always require a two-person team. For a 1,500 square foot home, that is 15 or more hours of two-person labor, not counting setup and inspection time.
Older homes take longer because walls are harder to access and the existing wiring systems are more complex to remove safely.
2. Home size and layout
A larger home simply needs more wire, more outlets, more circuits, and more labor hours. But layout matters too. Open floor plans are faster to wire. Homes with multiple stories, finished basements, or complex rooflines take significantly longer. Each additional crawl space or attic section adds time.
3. Type of existing wiring
This is where costs can jump unexpectedly for owners of older homes:
- Knob and tube wiring (pre-1940s homes): Removal requires a special permit in most California cities. The labor involved in safely removing this brittle, ungrounded system adds $2,000 to $5,000 to most projects.
- Aluminum wiring (common in homes built 1965–1972): Must be replaced with copper to meet current safety standards, adding material and labor costs.
- Modern copper wiring in good condition: Some circuits may not need replacement, which can lower the overall scope and cost.
If you are unsure what wiring type your home has, a licensed electrician can inspect and tell you before you commit to any scope of work.
4. Electrical panels and additional costs
Most homes being rewired also need electrical panel work. If your panel is outdated or undersized, a rewire is the ideal time to upgrade it. A panel upgrade adds $2,500 to $4,500, but bundling it with the rewiring project typically saves $500 to $1,500 compared to doing the jobs separately.
Other additional costs to factor in:
- Permit fees: $200 to $1,000 depending on your city and project scope
- Drywall repair: Electricians open walls to run new wire; patching costs $300 to $1,500 or more
- Electrical inspection: $100 to $200 after work is completed
- Temporary housing: For larger homes where power will be off for several days
Signs Your Home Needs Rewiring
Many homeowners in Orange County live with wiring problems for years without realizing they have a serious safety issue. Here are the clearest warning signs:
- Burning smells near outlets or the electrical panel with no obvious source
- Lights that flicker or dim when you run appliances
- Outlets or switches that feel warm to the touch
- Frequently tripping circuit breakers that reset but trip again
- A home built before 1975 that has never had a full wiring inspection
- Discolored or charred outlet covers
Burning smells in particular should be treated as an emergency. They often signal wire insulation failing inside walls, which is a leading cause of residential electrical fires. Do not delay a professional inspection if you notice this.
Most older homes also benefit from a rewire before adding high-demand loads. Installing an EV charger, a heat pump, or solar panels on a home with outdated wiring systems creates serious safety risks. A licensed electrician can assess whether your current wiring can handle those loads or whether a rewire makes more sense first.

What the Rewiring Process Looks Like
Knowing the steps ahead helps you plan your schedule and budget accurately.
Step 1: Inspection and quote
A licensed electrician inspects your current wiring, notes the panel size, checks for knob and tube or aluminum wiring, and counts your circuits. This inspection is the basis for your quote. Reputable contractors will not give a firm number without seeing the home.
Step 2: Permits
Your electrician pulls the permits required by your city or county. In Orange County, this typically involves the local building department. Work cannot legally begin without a permit in place. Be cautious of any contractor who suggests skipping this step.
Step 3: Wiring installation
The crew opens walls strategically, fishes new wire through cavities, installs new outlets and switches, and connects everything to the panel. A good crew minimizes wall damage by using the attic, basement, or existing access points wherever possible.
Step 4: Inspection and close-out
After the work is complete, a city or county inspector visits to verify the installation meets local codes. Once it passes, the walls are patched and the project is done. Your electrician should provide you with all permit documentation for your records.
How to Get an Accurate Quote
Getting three quotes is standard advice, but here is what makes a rewiring quote actually useful:
- Ask for an itemized breakdown. Labor, materials, permits, and any drywall repair should appear as separate line items.
- Ask about scope. A partial rewire costs less but may not solve the underlying problem. Make sure you understand exactly which circuits and rooms are included.
- Confirm licensing and insurance. In California, electrical contractors must hold a C-10 license from the CSLB. You can verify any contractor’s license at the California Contractors State License Board.
- Ask about bundling. If your panel is aging, ask what it costs to include a panel upgrade in the same project. In some cases, upgrading the panel alone may be enough if your wiring is still in good condition.

FAQ
How much does an electrician charge to wire a whole house?
For a complete rewire in Orange County, most homeowners expect to pay between $8,000 and $30,000, depending on home size, wiring condition, and whether a panel upgrade is needed. Labor costs typically account for 60 to 70 percent of that total. An electrician charges roughly $85 to $130 per hour in Southern California, and most full rewiring projects require a two-person crew working 5 to 14 days.
How much would it cost to rewire a 2,000 square foot house?
A 2,000 square foot home in Orange County typically costs $14,000 to $20,000 to rewire. That estimate assumes standard copper wiring, a two-person crew, and permit fees. If the home has knob and tube wiring or needs a panel upgrade, expect the number to sit toward the higher end or slightly above that range.
How much should a full house rewire cost?
A full house rewire in California generally runs $6 to $10 per square foot, all in. For an average-sized home of around 1,500 square feet, that works out to $9,000 to $15,000 before any additional costs like panel work or drywall repair. The final number depends heavily on labor rates in your area, the age of your wiring systems, and permit requirements.
How long does it take to rewire a 1,000 sq ft house?
A 1,000 square foot home typically takes 3 to 5 days to rewire with a two-person crew. Older homes with knob and tube wiring take longer because of the extra removal work and stricter permitting requirements. The inspection at the end adds one more scheduled visit, usually within a day or two of project completion.
