Home Rewiring Cost Guide, 2026 Pricing Breakdown

The national average cost to rewire a home is approximately $12,000–$18,000 for a mid-size house, with most projects falling between $8,000 and $30,000 depending on home size, scope of work, and regional labor rates. On a per-square-foot basis, complete rewiring typically runs $3–$9 per square foot.

This guide compiles cost data across six dimensions: home size, project scope, labor, materials, add-on costs, and regional variation. It draws from primary sources, including Bureau of Labor Statistics occupational wage data and Gordian’s quarterly construction materials index.

Home Rewiring Cost by Square Footage

Home size is the single largest driver of total rewiring cost. Larger homes require more wire, more outlets, and more labor hours. The table below estimates the total project cost by square footage at the national average rate of $3–$9 per square foot for a complete rewire, including labor and materials. Costs assume copper wiring, standard accessibility, and no panel upgrade.

Home Size (sq ft) Low Estimate Mid Estimate High Estimate Approx. Labor Days
800 sq ft $2,400 $4,800 $7,200 2–4 days
1,000 sq ft $3,000 $6,000 $9,000 3–5 days
1,200 sq ft $3,600 $7,200 $10,800 3–5 days
1,500 sq ft $4,500 $9,000 $13,500 4–6 days
1,800 sq ft $5,400 $10,800 $16,200 5–7 days
2,000 sq ft $6,000 $12,000 $18,000 5–8 days
2,500 sq ft $7,500 $15,000 $22,500 6–10 days
3,000 sq ft $9,000 $18,000 $27,000 7–10 days
3,500 sq ft $10,500 $21,000 $31,500 8–12 days

Note: Labor timeline assumes a 2–3 person crew. Older homes with plaster walls, tight attics, or limited crawlspace access can add 20–30% to both time and cost. Panel upgrades, permits, and drywall repair are not included in these figures.

 

Home Rewiring Cost by Scope of Work

Not all rewiring projects are the same. The table below breaks down typical cost ranges by scope, from a single-room update to a full-house replacement. Costs include labor and materials but exclude permits and panel upgrades unless noted.

Scope of Work Typical Cost Range Notes
Single room (basic update) $600–$2,500 Bedroom, office, or laundry room; minimal wall access needed
Kitchen rewire $1,500–$4,000 Dedicated circuits for appliances increase complexity
Partial rewire (1–2 floors) $3,000–$10,000 Selective upgrade of outdated circuits or knob-and-tube sections
Full house rewire, new construction $4,000–$9,000 Open walls allow faster, lower-cost installation ($3–$5/sq ft)
Full house rewire, existing home $8,000–$30,000 Finished walls increase labor significantly ($5–$9/sq ft)
Full house + panel upgrade $10,000–$35,000 Includes 200-amp service panel replacement
Knob-and-tube replacement $15,000–$40,000 Pre-1940s systems; extensive labor due to access challenges
Aluminum wiring remediation $8,000–$20,000 Homes built 1965–1972; may require pigtailing or full replacement

Why the range is wide: The biggest variable is wall access. If electricians can run wire through an open attic, basement, or crawlspace, labor costs drop significantly. Homes with finished ceilings, concrete block walls, or multiple additions require more cutting, patching, and fishing, which drives costs toward the high end.

 

Home Rewiring Labor Cost Breakdown

Labor accounts for up to 70% of the total cost of a home rewiring project. Electricians bill at different rates depending on license level, whether they are union or non-union, and regional market conditions.

National electrician wage data (BLS, May 2024)

Home Rewiring Materials Cost Breakdown

Materials typically represent 30–60% of total rewiring cost. Copper wire is the primary material expense and has experienced significant price volatility in recent years.

Copper wire pricing trends

According to Gordian’s quarterly construction cost index, copper electric wire prices have risen for five consecutive quarters as of Q4 2025, with costs up approximately 8.9% year-over-year. The national average price for copper electric wire stood at $393.64 per MLF (thousand linear square feet) as of Q3 2025.

Broader market context: copper wire prices are up roughly 15% since Q4 2023, driven by sustained demand from renewable energy projects, EV infrastructure, and data center construction, all of which compete for the same copper supply as residential contractors.

Period Copper Wire Price (National Avg.) QoQ Change YoY Change
Q1 2025 $395.15/MLF +0.76% +8.9%
Q2 2025 Peak quarter +7.86% vs. Q1 +15.2%
Q3 2025 $393.64/MLF -0.37% (slight dip) +8.9%
Q4 2025 (conduit) $127.88/CLF Flat vs. Q3 +1.63%

Common residential wiring materials and cost ranges

The following table covers the primary materials involved in a full home rewire. Prices reflect typical residential-grade materials and do not include labor.

Material Unit Typical Cost Range Notes
NM-B cable (Romex) 14/2 Per linear foot $0.50–$1.20 Standard branch circuit wiring
NM-B cable (Romex) 12/2 Per linear foot $0.80–$1.80 20-amp circuits (kitchens, baths)
NM-B cable (Romex) 10/2 Per linear foot $1.20–$2.50 240V appliance circuits
Electrical conduit (EMT) Per 10-ft section $8–$20 Required in exposed areas by some codes
Standard outlet (duplex) Per unit $2–$8 Material only
GFCI outlet Per unit $15–$35 Required in wet areas by NEC
AFCI circuit breaker Per unit $35–$75 Required in most rooms per 2023 NEC
200-amp service panel Per unit $15–$400 Panel only; installation adds $1,200–$2,600
Light switch (single-pole) Per unit $2–$8 Material only

Tariff impact (2025): New tariffs enacted in 2025 include a 25% duty on steel and aluminum imports. These policies have contributed to copper wire prices rising 14–17% since early 2025, per industry reporting. Budget estimates for projects beginning mid-2025 or later should account for this elevated baseline.

 

Additional Cost Factors for Home Rewiring

Most rewiring quotes do not include every line item a homeowner will ultimately pay. The following costs are commonly added to the base labor and materials estimate.

Cost Item Typical Range Notes
Electrical permit $75–$1,000 Varies widely by municipality; required for all rewiring work
Electrical inspection $100–$400 Usually required before and after; may be bundled with permit fee
200-amp panel upgrade (installed) $1,500–$3,000 Required if existing panel is undersized or outdated
Drywall repair (labor) 20–30% labor surcharge Opening walls for wire access requires patching and painting
AFCI/GFCI breaker upgrades $75 per breaker 2023 NEC requires AFCI protection in most living spaces
Attic/crawlspace access surcharge $500–$2,000 Added if conditions make wire routing significantly harder
Panel relocation $1,000–$3,000 Moving the service panel to a new location
General contractor markup 13–22% of total If a GC is coordinating the electrical subcontractor
Service entrance upgrade $3,000–$5,000 Upgrading utility connection to the home; utility involvement required
Grounding system upgrade $300–$800 Often needed in homes built before modern grounding requirements

Budgeting tip: Industry contractors consistently advise homeowners to add 15–25% to any base rewiring estimate to account for hidden conditions discovered during the project, especially in homes over 30 years old, where access and condition are unknown until walls are opened.

 

Regional Cost Variation by State

2015 24,500 290 850 $1.22B
2016 23,500 310 800 $1.15B
2017 24,100 200 750 $1.31B
2018 25,700 255 825 $1.49B
2019 24,200 225 1,050 $1.44B
2020 23,400 200 975 $1.34B
2021 24,200 295 900 $1.35B
2022 26,100 185 850 $1.55B
2023 (most recent) 23,700 305 800 $1.50B

Source: U.S. Fire Administration / FEMA, “Residential Building Electrical Malfunction Fire Trends (2014–2023),” page last reviewed February 14, 2025. Dollar loss figures adjusted to 2023 constant dollars.

10-year trend summary (2014–2023)

  • Fires: +2% over the 10-year period
  • Deaths: -19% over the 10-year period
  • Injuries: +2% over the 10-year period
  • Dollar loss: +28% over the 10-year period (inflation-adjusted)

The decline in deaths alongside rising fire counts and property loss reflects improved detection technology (smoke alarms, AFCI breakers) but also the increasing value of homes and contents. The data makes clear that while fatalities have trended down, electrical fires continue to cause substantial injury and financial harm.

 

Wiring types associated with elevated risk

Wiring Type Era Risk Profile Recommended Action
Knob-and-tube Pre-1940s Not grounded; insulation deteriorates; not rated for modern loads Full replacement strongly recommended
Aluminum branch circuit wiring 1965–1972 Expands/contracts with heat; connections loosen over time; fire risk at outlets and switches Remediation or full replacement
60-amp service panels Pre-1970s Cannot support modern electrical loads; frequently trips Panel upgrade to 200-amp service
Two-prong (ungrounded) outlets Pre-1960s No ground path; equipment damage and shock risk Grounded outlet upgrade or GFCI protection

 

Key Takeaways

  • The national average cost to rewire a home is $12,000–$18,000 for a mid-size house, with most projects falling between $8,000 and $30,000 depending on size, scope, and location.
  • Regional cost differences can account for up to 2x the total cost of rewiring a home, with projects on the West Coast and in the Northeast averaging roughly double the cost of projects in the South and Midwest.
  • Most base quotes do not include permits, inspections, drywall repair, or panel upgrades, which can add $3,000–$5,000 or more. Budget 15–25% above any base estimate, especially in homes over 30 years old.
  • Copper wire prices are up approximately 15% since Q4 2023 and have risen for five consecutive quarters as of Q4 2025, driven by competition from renewable energy and EV infrastructure projects.
  • Residential electrical malfunction fires caused 23,700 fires, 305 deaths, and $1.5 billion in property loss in 2023 (USFA/FEMA). Homes with knob-and-tube wiring (pre-1940s) or aluminum branch-circuit wiring (1965–1972) pose the highest risk.
  • The 2023 National Electrical Code expanded AFCI breaker requirements to most living spaces. Homes that do not meet current code may face compliance requirements during renovation or sale.
