Whole house electrical wiring typically costs $8,000-$15,000 to replace in a 1,500-square-foot home, with difficult access or extensive code upgrades pushing the bill higher. Whole house electrical wiring cost depends most on home size, wall access, circuit needs, local labor rates, and whether the panel also needs replacement.

| Rewiring rate | $6 per sq ft | $8 per sq ft | $12 per sq ft | Typical existing-home range |
| Panel replacement | $1,500 | $3,000 | $5,000 | May be separate from wiring |
| Permit and inspection | $100 | $400 | $1,000 | Local fees and scope vary |
What a full home rewire costs by square footage
For an existing home, a broad planning range is $6-$12 per square foot, including typical wire, devices, and electrician labor. An 800-square-foot home may cost $4,800-$9,600; a 1,500-square-foot home, $9,000-$18,000; and a 2,500-square-foot home, $15,000-$30,000. Partial rewiring can cost less if only a defined area or a few circuits need replacement.
Quotes vary with finish quality and site conditions. Open walls, accessible basements, and straightforward layouts tend to reduce labor; finished plaster, multiple stories, and limited crawlspace access can increase it. Assumptions: standard copper wiring, ordinary access, and midrange U.S. labor rates. A typical complete rewire often lands near $8,000-$15,000 for a modest-to-mid-sized home.
How wire, electrician labor, and panel work shape the quote
Labor is often the largest line item because electricians must route cable, connect devices, and test circuits throughout the home. Material costs depend on wire length, circuit count, receptacles, switches, and code-required protection. A panel upgrade is not automatically included in a rewire estimate.
| Quote component | Typical range | What changes the price | Unit or scope |
|---|---|---|---|
| Electrician labor | $3,000-$10,000 | Access, crew size, and circuit count | $75-$150 per hour |
| Wire and cable | $800-$3,000 | Gauge, length, and copper pricing | $0.50-$2 per linear ft |
| Outlets, switches, and protection | $500-$2,500 | Device count and GFCI/AFCI needs | $10-$100 per device |
| Panel and breakers | $1,500-$5,000 | Service capacity and relocation | One panel installation |
| Permits and wall repair | $300-$3,000 | Local fees and finish restoration | Project allowance |
Labor estimates can be checked by multiplying the quoted crew hours by the electrician’s hourly rate, while accounting for multiple workers. Ask whether patching, painting, permits, and panel work are included or priced separately.
Why home size and circuit load change rewire pricing
Square footage is a starting point, not a complete measure. A 1,200-square-foot home with a complex layout or many kitchen and laundry circuits can cost more than a larger, simpler house. A second story, detached garage, finished basement, or long cable runs also add time and materials.
Electrical capacity matters too. Homes with a 60-amp or 100-amp service may need a panel or service upgrade if the new circuit plan exceeds available capacity; a 200-amp service may avoid that added work when its condition and load calculation permit. Adding an electric range, heat pump, or EV charger can require dedicated circuits. Each added circuit may add roughly $150-$500, depending on route length and installation difficulty.
Cut costs by controlling access, scope, and finish work
Homeowners can lower the quote by clearing work areas, identifying existing wiring concerns, and deciding in advance which rooms and devices are part of the project. If walls are already open during a renovation, coordinating the rewire with other trades can avoid separate demolition and patching. Avoid paying for upgraded fixtures or unnecessary circuit additions unless the design or code requires them.
Compare at least three detailed estimates using the same scope: number of outlets and circuits, panel work, permit handling, testing, and wall repairs. A low bid that excludes restoration or code-required devices may not be the lowest final price. Keep the quote itemized so optional upgrades remain separate from safety or code work.
How long electricians need for an occupied or empty house
A small, accessible home may take 3-5 working days, while a 2,000-square-foot house with limited access can take 1-2 weeks or longer. A crew of two or three electricians may work in parallel, but inspection timing and drywall repairs can extend the calendar schedule. Occupied homes may require staged work room by room, increasing labor and inconvenience.
Ask how many days the power will be interrupted and whether temporary power or phased reconnection is included. Scheduling the work while the home is vacant or under renovation can reduce setup time and wall-repair expense.
Old plaster, attic access, and disposal add-ons to budget
Removing abandoned wiring, opening plaster walls, or fishing cable through insulated cavities can add several thousand dollars. Wall and ceiling repair commonly adds $500-$3,000, depending on the number and size of openings and whether painting is included. Disposal of old cable is usually modest, but removal of hazardous material requires separate qualified handling and pricing.
Some contractors charge a diagnostic or minimum service fee of $100-$300 before preparing a larger project estimate. Ask whether that fee is credited toward the job. Get written allowances for concealed damage and restoration before work begins.
Regional electrician rates shift whole-house wiring quotes
Labor markets make regional comparisons useful but imperfect. Major coastal cities and high-cost metro areas may run about 15%-30% above national planning ranges, while rural markets may be 5%-15% lower when contractors are available. Remote travel, limited electrician availability, and local permit rules can offset rural savings.
For example, a project estimated at $12,000 in a mid-cost market might reach $13,800-$15,600 in a high-cost city, or fall near $10,200-$11,400 in a lower-cost area before unusual access or code work. Use local written quotes rather than applying a national average as a guaranteed price.
When partial rewiring costs less than replacing every circuit
Replacing damaged or outdated wiring in one room or on selected circuits may cost $1,500-$5,000, depending on access and how much of the circuit must be replaced. A targeted repair can be appropriate when an electrician confirms the remaining wiring is serviceable and the home’s safety needs are addressed. It may not solve widespread deterioration or inadequate capacity.
Ask the electrician to distinguish repair, partial rewire, and full replacement in writing, including the condition and location of wiring left in place. Compare the immediate repair price with the cost of completing a full rewire later, especially before major wall renovations.
