The short answer: Rewiring a house costs between $4,000 and $15,000 for most US homeowners in 2026. A typical 1,500 sq ft home with standard access runs $6,000 to $10,000, while larger or older homes with plaster walls, limited attic access, or knob-and-tube wiring can push costs to $15,000 to $25,000 or more. The national average sits around $8,200 including permits, labor, and materials.
If you are reading this, your home probably has outdated wiring, and you are trying to figure out whether this is a $3,000 problem or a $20,000 problem. The honest answer depends on your home’s age, size, and how much of the existing wiring needs to come out. This guide breaks down every cost factor so you can compare quotes with confidence and avoid overpaying.
Before hiring anyone for this job, make sure you know how to find a trustworthy contractor since electrical work is one of the most commonly botched home improvement projects.
What You Are Actually Paying For
Rewiring a house is not one single job. It involves several components, and understanding each one helps you read quotes accurately and negotiate fairly.
Wire and Materials
The wire itself is the smallest part of the bill, typically 15 to 25 percent of total cost. A full rewire for a 1,500 sq ft home requires roughly 1,500 to 2,500 feet of Romex (NM-B) cable. At current copper prices, that is $800 to $2,000 in materials including outlets, switches, junction boxes, and connectors.
Labor
Labor is the biggest expense, accounting for 60 to 75 percent of the total. Electricians typically charge $65 to $130 per hour depending on your region, and a full rewire takes 3 to 10 days depending on home size and complexity. A straightforward ranch-style home with open attic access might take 3 to 4 days. A two-story colonial with plaster walls and no attic access could take 7 to 10 days.
Electrical Panel Upgrade
Many rewiring projects also require an electrical panel upgrade. If your home still has a 60-amp or 100-amp panel, your electrician will likely recommend upgrading to 200 amps. This adds $1,500 to $4,000 to the project but is often necessary to handle modern electrical loads safely.
Permits and Inspections
Every jurisdiction in the US requires permits for rewiring work. Permit fees range from $75 to $500 depending on your city or county. The inspection process typically involves a rough-in inspection (before walls are closed up) and a final inspection. Never let an electrician skip the permit. Unpermitted electrical work can void your homeowners insurance, create problems at resale, and most importantly, put your family at risk.
Wall Repair and Patching
This is the cost that surprises most homeowners. Running new wire through finished walls requires cutting access holes. After the electrical work is done, someone has to patch and paint those holes. Wall repair typically adds $1,000 to $3,000 to the total project. Some electricians include basic patching in their quote; others leave it to you. Ask upfront.
Cost Breakdown by Home Size
Here is what full rewiring typically costs based on square footage:
| Home Size | Typical Cost Range | Average | Estimated Duration |
|---|---|---|---|
| 1,000 sq ft | $3,500-$7,000 | $5,000 | 2-4 days |
| 1,500 sq ft | $5,000-$10,000 | $7,500 | 3-5 days |
| 2,000 sq ft | $7,000-$13,000 | $9,500 | 4-7 days |
| 2,500 sq ft | $9,000-$16,000 | $12,000 | 5-8 days |
| 3,000 sq ft | $11,000-$20,000 | $15,000 | 6-10 days |
| 3,500+ sq ft | $14,000-$25,000+ | $18,000+ | 8-12 days |
These ranges include standard materials, labor, permits, and basic wall patching. They do not include panel upgrades, which are quoted separately.
How Costs Vary by State
Labor rates drive the biggest regional differences:
| Region | Cost per Sq Ft | 1,500 Sq Ft Home Total |
|---|---|---|
| Northeast (NY, MA, CT, NJ) | $6-$10 | $9,000-$15,000 |
| Pacific Coast (CA, WA, OR) | $6-$11 | $9,000-$16,500 |
| Mid-Atlantic (DC, MD, VA) | $5-$8 | $7,500-$12,000 |
| Midwest (OH, IL, MI, MN) | $4-$7 | $6,000-$10,500 |
| South (TX, FL, GA, NC) | $3.50-$6.50 | $5,250-$9,750 |
| Mountain West (CO, AZ, UT) | $4.50-$7.50 | $6,750-$11,250 |
California and New York homeowners consistently pay the most due to higher labor rates and stricter code requirements. Texas and southeastern states tend to have the lowest rewiring costs.
Signs Your Home Needs Rewiring
Not every older home needs a complete rewire. Here are the warning signs that indicate a full rewire is necessary rather than targeted repairs:
Immediate safety concerns (get an inspection now):
- Burning smell from outlets or switches with no visible source
- Scorch marks or discoloration around outlets
- Breakers trip frequently even with normal loads
- Lights flicker when appliances turn on
- Two-prong outlets throughout the house (no grounding)
- Visible knob-and-tube or aluminum wiring
Strong indicators (plan for rewiring within 1-2 years):
- Home was built before 1965 and has never been rewired
- Fuse box instead of circuit breaker panel
- Not enough outlets, leading to heavy extension cord use
- Insurance company has flagged the wiring or increased premiums
- You are planning a major renovation or addition
Partial rewire may be enough:
- Only one section of the home has old wiring
- You are adding a room or finishing a basement
- Panel upgrade alone solves the capacity issue
- Previous owner did a partial update that covers the main living areas
A licensed electrician can do a full home electrical inspection for $200 to $400, and this is money well spent before committing to a $10,000+ project.
Knob-and-Tube Wiring: Why It Costs More
If your home was built before 1950, you may have knob-and-tube wiring. This old system runs individual wires through ceramic knobs and tubes rather than bundled cable. It is not inherently dangerous when properly maintained, but it was never designed for modern electrical loads, cannot be grounded, and becomes a fire hazard when insulation covers it.
Removing knob-and-tube wiring and replacing it with modern Romex adds 20 to 40 percent to the cost of a standard rewire. The extra cost comes from the careful removal process and the additional access points needed in walls and ceilings.
Many home insurance companies either refuse to insure homes with active knob-and-tube wiring or charge significantly higher premiums. If your homeowners insurance company is pressuring you about wiring, they may actually be doing you a favor by pushing you toward a safer system.
Partial Rewire vs. Full Rewire
You do not always need to rewire the entire house. A partial rewire focuses on specific areas and can save significant money:
| Scope | Typical Cost | When It Makes Sense |
|---|---|---|
| Single room | $500-$2,000 | Renovation or addition |
| Kitchen only | $1,500-$4,000 | Kitchen remodel, need GFCI and dedicated circuits |
| Bathroom only | $800-$2,500 | Bathroom remodel, need GFCI protection |
| One floor | $2,500-$6,000 | Upper floor has old wiring, main floor was updated |
| Add circuits only | $200-$500 per circuit | Enough outlets, just need more capacity |
A good electrician will be honest about whether a partial rewire is sufficient for your situation. If someone pushes a full rewire when targeted work would solve the problem, get a second opinion.
How to Save Money Without Cutting Corners
Electrical work is not the place to bargain-hunt, but there are legitimate ways to reduce costs:
Get three written quotes. Prices vary significantly between electricians. On a $10,000 job, three quotes could reveal a $2,000 to $4,000 spread.
Time it with other renovations. If you are already gutting a kitchen or remodeling a bathroom, the walls are already open. Rewiring during a renovation can cut labor costs by 30 to 50 percent because the electrician does not have to cut and repair access holes.
Do the wall patching yourself. If you are handy with drywall, doing the patching and painting after the electrician finishes can save $1,000 to $3,000. Just make sure the electrical inspection is completed before you close up any walls.
Ask about phased work. Some electricians will rewire your home in phases if budget is tight. You might do the most critical areas (kitchen, panel, main living spaces) this year and bedrooms next year.
Check for utility rebates. Some utility companies offer rebates for electrical panel upgrades, especially when they support electric vehicle charging or heat pump installation. Check dsireusa.org for programs in your state.
DIY vs. Hiring a Pro
This is straightforward: do not attempt to rewire your house yourself. Electrical work requires a permit and licensed professional in every US state. DIY electrical work that causes a fire will void your homeowners insurance and can result in criminal liability. This is not like painting your interior where DIY is a legitimate money-saving option.
You can do minor tasks like replacing outlets and light switches if your local code allows it, but anything involving running new wire through walls, upgrading panels, or modifying circuits should be done by a licensed electrician.
Questions to Ask Your Electrician Before Hiring
Before signing a contract, ask these questions:
- Are you licensed and insured? (Verify independently through your state licensing board)
- Does your quote include permits and inspections?
- Will you handle wall patching, or do I need to hire someone separately?
- What type and gauge of wire will you use?
- Is a panel upgrade included? If not, do I need one?
- How many new outlets and circuits will be added?
- Do you warranty your work, and for how long?
- What is the timeline, and will I need to leave the house during any part of the work?
A good electrician will answer all of these without hesitation. If someone gets evasive about licensing or permits, move on.
The Federal Tax Credit Angle
While there is no direct federal tax credit for standard rewiring, an electrical panel upgrade to support a heat pump or EV charger can qualify for the Inflation Reduction Act’s energy-efficient home improvement credit. If your rewire includes a panel upgrade for these purposes, you may be able to claim up to $600. Check the IRS energy credits page for current eligibility.
