Homeowners typically pay a broad range for a full house rewire due to factors like home size, age, wiring type, labor costs, and permit requirements. This article presents cost estimates in USD, with clear low-average-high ranges and unit pricing where relevant, to help plan a project budget for a house rewire.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Total Project | $5,000 | $9,500 | $20,000 | Assumes mid-sized single-family home, standard access, and typical old-knob-and-theatre wiring replaced |
| Per Square Foot | $4 | $6 | $9 | Includes materials and labor for new wiring, outlets, and panel upgrade if needed |
| Panel Upgrade | $1,000 | $2,500 | $5,000 | Depends on panel type and capacity (main breaker, service disconnect) |
| Labor (Labor-Only) | $3,000 | $6,000 | $12,000 | Includes rough-in, device install, and testing |
| Permits & Inspections | $400 | $1,200 | $2,000 | Varies by jurisdiction and scope |
Assumptions: Midwest labor rates, standard 100-amp service, three-bedroom home, normal attic/crawlspace access, and no special seismic or high-end smart-home wiring.
What Buyers Usually Pay For a House Rewire
Most projects fall in the $5,000–$20,000 range, with mid-size homes near $9,000–$15,000. The main price driver is the square footage wired, the existing electrical system’s complexity, and whether a full panel upgrade is required. For smaller homes under 1,200 square feet, expect toward the lower end; larger homes or those with multiple stories push costs up. Per-square-foot pricing helps compare bids when a contractor quotes a wide total.
| Cost Component | Typical Range | What Drives It |
|---|---|---|
| Materials (cables, devices, breakers) | $2,000–$6,000 | Wire gauge, number of circuits, AFCI/GFCI requirements |
| Labor | $3,000–$12,000 | Crew size, hours, accessibility, attic/crawlspace access |
| Panel Upgrade | $1,000–$5,000 | Service size, main breaker, subpanels |
| Permits/Inspections | $400–$2,000 | Local permit fees, electrical inspection scope |
| Delivery/Disposal | $100–$1,000 | Old wiring disposal, hazardous material handling |
Assumptions: standard 8–12 hour days, electrical crew rates $75–$125 per hour depending on region and crew expertise.
Key Variables That Change the Final Quote
House size, service level, and access conditions are the biggest price levers. A 1,200–1,600 sq ft home with standard attic access and a 100-amp service is far cheaper than a 2,800 sq ft house with difficult crawlspace access and a 200-amp service upgrade. Regional wage differences can add 10–25% to labor. Complex wiring layouts, antique components, or required smart-home integration can push totals higher.
| Driver | Typical Impact | Thresholds |
|---|---|---|
| House Size (sq ft) | Higher by 20–40% as size grows | Under 1,200 vs 2,400+ |
| Panel Capacity | Up to 2x cost when upgrading to 200-amp | 100A vs 200A |
| Access Quality | Can add $1,000–$4,000 | Attic crawlspace vs open attic |
| Old Wiring Type | Knob-and-tube requires more labor | From 1940s wiring |
| Region | Labor cost variance 10–25% | Midwest vs West Coast |
How to Trim the Price Without Compromising Safety
Scope control and upfront planning reduce surprises. Get an itemized quote that separates materials, labor, and permits. If possible, time the project to avoid peak demand, and compare at least three bids that use the same scope. Consider upgrading only essential circuits first and deferring specialty circuits until later if feasible.
- Compare regional bids to reflect local labor costs and permit fees.
- Bundle adjacent electrical upgrades (outlets, switches, lighting) with the rewire for potential savings.
- Ask about phased work: rough-in first, finishes second if budget is tight.
Regional Pricing Nuances for the Average Rewire
Costs vary by region due to labor rates and permit regimes. In the Northeast, a full rewire tends toward the higher end of the range; in the South or Midwest, prices trend lower. Labor-heavy markets with high costs per hour will push the total toward the upper end, especially for homes with limited access or older wiring.
Per-Unit and Per-Square-Foot Comparisons
Per-square-foot pricing helps when bids differ on scope. A mid-range home at 1,600 sq ft might cost $6–$9 per sq ft for basic rewiring, or more if a full panel upgrade and advanced AFCI/GFCI protection are required. For very small homes, a flat-bid can be more economical, while large homes often benefit from a measured, per-square-foot approach.
| Scenario | Low Range | Average Range | High Range | Notes |
|---|---|---|---|---|
| 1,200 sq ft, basic rewire | $5,000 | $8,000 | $12,000 | Mostly new circuits, standard outlets |
| 2,000 sq ft, panel upgrade | $8,000 | $14,000 | $22,000 | 200-amp service |
| 2,800 sq ft, full smart-home wiring | $12,000 | $20,000 | $35,000 | Advanced devices, structured wiring |
Timing and Scheduling Impact on Price
Emergency or rush work carries a premium. If a permit and inspection timeline overlaps with high-demand seasons, expect higher bids. Allow a few weeks for project ramp-up in busy markets to avoid premium scheduling charges. A typical rewire can span several days to a couple of weeks depending on scope and access.
Add-Ons and Common Disposals That Affect Cost
Disposal of old wiring and devices adds modest fees. Expect separate line items for old wiring haul-away, device removal, and cleanup. If any asbestos or other hazardous materials are discovered, costs can increase significantly due to special handling and disposal requirements.
- Old wiring disposal: $100–$600
- Device replacement (outlets/switches): $2–$10 per device
- Smart-home module integrations: $200–$1,000
